SECTION II: SAFETY

This is a safety alert symbol. When you see this symbol on

labels or in manuals, be alert to the potential for personal

injury.

Understand and pay particular attention to the signal words DANGER,

WARNING, or CAUTION.

DANGER indicates an imminently hazardous situation, which, if not

avoided, will result in death or serious injury.

WARNING indicates a potentially hazardous situation, which, if not

avoided, could result in death or serious injury.

CAUTION indicates a potentially hazardous situation, which, if not

avoided may result in minor or moderate injury. It is also used to

alert against unsafe practices and hazards involving only property dam-

age.

INSPECTION

As soon as a unit is received, it should be inspected for possible dam-

age during transit. If damage is evident, the extent of the damage

should be noted on the carrier’s delivery receipt. A separate request for

inspection by the carrier’s agent should be made in writing. See Local

Distributor for more information.

Requirements For Installing/Servicing R-410A Equipment

• Gauge sets, hoses, refrigerant containers, and recovery system

must be designed to handle the POE type oils, and the higher

pressures of R-410A.

• Manifold sets should be high side and low side with low side

retard.

• All hoses must have a 700 psig service pressure rating.

• Leak detectors should be designed to detect HFC refrigerant.

• Recovery equipment (including refrigerant recovery containers)

must be specifically designed to handle R-410A.

• Do not use an R-22 TXV.

LIMITATIONS

The unit should be installed in accordance with all National, State and

Local Safety Codes and the limitations listed below:

1. Limitations for the indoor unit, coil, and appropriate accessories

must also be observed.

2. The outdoor unit must not be installed with any duct work in the air

stream. The outdoor fan is the propeller type and is not designed

to operate against any additional external static pressure.

3. The maximum and minimum conditions for operation must be

observed to ensure a system that will give maximum performance

and service life.

The unit should not be operated in cooling mode at outdoor temperatures below

50°F without an approved low ambient operation accessory kit installed.

The maximum allowable line length for this product is 80 feet. To install more

than the maximum allowable line length, consult the Piping Application Guide

(P/N 247077).

SECTION III: UNIT INSTALLATION

LOCATION

Before starting the installation, select and check the suitability of the

location for both the indoor and outdoor unit. Observe all limitations and

clearance requirements.

The outdoor unit must have sufficient clearance for air entrance to the

outdoor coil, air discharge, and service access. See Figures 1 & 2.

If the unit is to be installed on a hot sun exposed roof or a paved ground

area that is seasonally hot, the unit should be raised sufficiently above

the roof or ground to avoid taking the accumulated layer of hot air into

the outdoor unit.

If the system is being installed during seasonally cold weather of 55°F

or below, the preferred method is to weigh in the charge. For charging

or checking the system charge at 55°F or below, refer to the “Optional

Cold Weather Charging” procedures near the end of SECTION VI:

SYSTEM CHARGE. There is an “Optional Cold Weather Charging”

accessory kit to prevent the outdoor unit from taking in cold air below

55°F. The kit part number can be found in the list of accessory kits on

the UPGNET web site.

Provide adequate structural support for the unit.

ADD-ON REPLACEMENT/RETROFIT

When this unit is being used as a replacement for an R-410A unit, it is

required that the outdoor unit, indoor coil, and metering device all be

replaced. The following steps should be performed in order to insure

proper system operation and performance. Line-set change out is also

recommended.

1. Change-out of the indoor coil to an approved R-410Acoil/ condens-

ing unit combination with the appropriate metering device.

2. Change-out of the line-set when replacing an R-22 unit with an

R410-A unit is highly recommended to reduce cross-contamina-

tion of oils and refrigerants.

3. If change-out of the line set is not practical, then the following pre-

cautions should be taken.

• Inspect the line set for kinks, sharp bends, or other restrictions,

and for corrosion.

• Determine if there are any low spots which might be serving as oil

traps.

• Flush the line set with a commercially available flush kit to

remove as much of the existing oil and contaminants as possible.

• Install a suction line filter-drier to trap any remaining contami-

nants, and remove after 50 hours of operation.

4. If the outdoor unit is being replaced due to a compressor burnout,

then installation of a 100% activated alumina suction-line filter

drier in the suction-line is required, in addition to the factory

installed bi-flow liquid-line drier. Operate the system for 10 hours.

Monitor the suction drier pressure drop. If the pressure drop

exceeds 3 psig, replace both the suction-line and liquid-line driers.

After a total of 10 hours run time where the suction-line pressure

drop has not exceeded 3 psig, replace the liquid line drier, and

remove the suction-line drier. Never leave a suction-line drier in

the system longer than 50 hours of run time.

WARNING

Improper installation may create a condition where the operation of

the product could cause personal injury or property damage.

Improper installation, adjustment, alteration, service or maintenance

can cause injury or property damage. Refer to this manual for assis-

tance or for additional information, consult a qualified contractor,

installer or service agency.

CAUTION

This product must be installed in strict compliance with the enclosed

installation instructions and any applicable local, state, and national

codes including, but not limited to building, electrical, and mechanical

codes.

CAUTION

R-410A systems operate at higher pressures than R-22 systems. Do

not use R-22 service equipment or components on R-410A equip-

ment. Service equipment Must Be Rated for R-410A.

5878890-UIM-A-0220

4 Johnson Controls Ducted Systems

GROUND INSTALLATION

The unit may be installed at ground level on a solid base that will not

shift or settle, causing strain on the refrigerant lines and possible leaks.

The unit must be installed in as level a position as possible while main-

taining the clearances shown in Figures 1 & 2.

Normal operating sound levels may be objectionable if the unit is placed

directly under windows of certain rooms (bedrooms, study, etc.).

Condensate will drain from beneath the coil of the outdoor unit during

the defrost cycle. Normally this condensate may be allowed to drain

directly on the ground.

Elevate the unit sufficiently to prevent any blockage of the air entrances

by snow in areas where there will be snow accumulation. Check the

local weather bureau for the expected snow accumulation in your area.

Isolate the unit from rain gutters to avoid any possible wash out of the

foundation.

ROOF INSTALLATION

When installing units on a roof, the structure must be capable of sup-

porting the total weight of the unit, including a pad, lintels, rails, etc.,

which should be used to minimize the transmission of sound or vibra-

tion into the conditioned space.

WALL MOUNT INSTALLATION

Care must be taken to mount the outdoor unit on a solid base that is

sloped to shed water, secure from settlement, and is isolated from the

structural foundation or walls to prevent sound and vibration transmis-

sion into the living space.

On occasion, site conditions may require direct wall mounted brackets

to be used to locate and support the outdoor unit. In these applications,

care must be taken to address unit base pan support, structural integ-

rity, safe access and serviceability, as well as the possible sound and

vibration transmission into the structure. These applications are best

served by a properly engineered solution.

UNIT PLACEMENT

1. Provide a base in the pre-determined location.

2. Remove the shipping carton and inspect for possible damage.

3. Ensure that compressor tie-down bolts remain tightened.

4. Position the unit on the base provided.

LIQUID LINE FILTER-DRIER

The heat pumps have a solid core bi-flow filter/drier located on the liquid

line.

PIPING CONNECTIONS

The outdoor unit must be connected to the indoor coil using field sup-

plied refrigerant grade (ACR) copper tubing that is internally clean and

dry. Units should be installed only with the tubing sizes for approved

system combinations as specified in tabular data sheet. The charge

given is applicable for total tubing lengths up to 15 feet (4.6 m). See

Piping Application Guide (P/N 247077) for installing tubing of longer

lengths and elevation differences.

PRECAUTIONS DURING LINE INSTALLATION

1. Install the lines with as few bends as possible. Care must be taken

not to damage the couplings or kink the tubing. Use clean hard

drawn copper tubing where no appreciable amount of bending

around obstruction is necessary. If soft copper must be used, care

must be taken to avoid sharp bends which may cause a restriction.

2. The lines should be installed so that they will not obstruct service

access to the coil, air handling system, or filter.

3. Care must also be taken to isolate the refrigerant lines to minimize

noise transmission from the equipment to the structure.

4. The vapor line must be insulated with a minimum of 1/2” foam rub-

ber insulation (Armaflex or equivalent). Liquid lines that will be

exposed to direct sunlight, high temperatures, or excessive humid-

ity must also be insulated.

5. Tape and suspend the refrigerant lines as shown. DO NOT allow

tube metal-to-metal contact. See Figure 3.

6. Use PVC piping as a conduit for all underground installations as

shown in Figure 4. Buried lines should be kept as short as possible

to minimize the build up of liquid refrigerant in the vapor line during

long periods of shutdown.

7. Pack fiberglass insulation and a sealing material such as perma-

gum around refrigerant lines where they penetrate a wall to reduce

vibration and to retain some flexibility.

WARNING

The outdoor unit should not be installed in an area where mud or ice

could cause personal injury. Remember that condensate will drip from

the unit coil during heat and defrost cycles and that this condensate

will freeze when the temperature of the outdoor air is below 32°F.

NOTICE

Heat pumps will defrost periodically resulting in water drainage. The

unit should not be located where water drainage may freeze and cre-

ate a hazardous condition - such as sidewalks and steps.

CAUTION

Failure to use the same as the original factory drier or using a substi-

tute drier or a granular type may result in damage to the equipment.

NOTICE

Replacements for the liquid line drier must be exactly the same as

marked on the original factory drier. See Source 1 for O.E.M. replace-

ment driers.

R-410A Filter-Drier Source 1 Part No. Apply with Models

S1-32649682000 All

NOTICE

Using a larger than specified line size could result in oil return prob-

lems. Using too small a line will result in loss of capacity and other

problems caused by insufficient refrigerant flow. Slope horizontal

vapor lines at least 1" (2.5 cm) every 20 feet (6.1 m) toward the out-

door unit to facilitate proper oil return. If more than the 75 foot line

length is necessary, facilitate proper refrigerant velocity with adjusted

line diameter in accordance with the Piping Application Guide (P/N

247077).

CAUTION

This system uses R-410A refrigerant which operates at higher pres-

sures than R-22. No other refrigerant may be used in this system.

Gauge sets, hoses, refrigerant containers, and recovery system must

be designed to handle R-410A. If you are unsure, consult the equip-

ment manufacturer.

WARNING

Never install a suction-line filter drier in the liquid line of an R-410A

system. Failure to follow this warning can cause a fire, injury or death.

8. For systems with total line length exceeding 75 feet (22.86 m), see

Piping Application Guide (P/N 247077) for vapor and liquid line

sizing, calibration of liquid line pressure loss or gain, determination

of vapor line velocity, elevation limitations, TXV connections, sys-

tem charging, traps, etc.

PRECAUTIONS DURING BRAZING OF LINES

All outdoor unit and indoor coil connections are copper-to-copper and

should be brazed with a phosphorous-copper alloy material such as Sil-

fos-5 or equivalent. DO NOT use soft solder. The outdoor units have

reusable service valves on both the liquid and vapor connections. The

total system refrigerant charge is retained within the outdoor unit during

shipping and installation. The reusable service valves are provided to

evacuate and charge per this instruction.

Serious service problems can be avoided by taking adequate precau-

tions to assure an internally clean and dry system.

PRECAUTIONS DURING BRAZING SERVICE VALVE

Precautions should be taken to prevent heat damage to service valve

by wrapping a wet rag around it as shown in Figure 5. Also, protect all

painted surfaces, insulation, and plastic base during brazing.After braz-

ing, cool joint with wet rag.

Valve can be opened by removing the service valve cap and fully insert-

ing a hex wrench into the stem and backing out counter-clockwise until

valve stem just touches the chamfered retaining wall.

Connect the refrigerant lines using the following procedure:

1. Remove the cap and Schrader core from both the liquid and vapor

service valve service ports at the outdoor unit. Connect low pres-

sure nitrogen to the liquid line service port.

2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure

to wrap the valve body with a wet rag. Allow the nitrogen to con-

tinue flowing.

3. Carefully remove the plugs from the indoor liquid and vapor con-

nections at the indoor coil.

4. Braze the liquid line to the indoor coil liquid connection. Nitrogen

should be flowing through the indoor coil.

5. Slide the grommet away from the vapor connection at the indoor

coil. Braze the vapor line to the indoor coil vapor connection. After

the connection has cooled, slide the grommet back into original

position.

6. Protect the vapor valve with a wet rag and braze the vapor line con-

nection to the outdoor unit. The nitrogen flow should be exiting the

system from the vapor service port connection. After this connec-

tion has cooled, remove the nitrogen source from the liquid fitting

service port.

7. Replace the Schrader core in the liquid and vapor valves.

8. Go to SECTION IV for TXV installation.

9. Leak test all refrigerant piping connections including the service

port flare caps to be sure they are leak tight. DO NOT OVER-

TIGHTEN (between 40 and 60 inch - lbs. maximum).

10. Evacuate the vapor line, indoor coil, and liquid line to 500 microns

or less. See Section V.

11. Replace cap on service ports. Do not remove the flare caps from

the service ports except when necessary for servicing the system.

12. Release the refrigerant charge into the system. Open both the liq-

uid and vapor valves by removing the service valve cap and with

an allen wrench back out counter-clockwise until valve stem just

touches the chamfered retaining wall. If the service valve is a ball

valve, use a Crescent wrench to turn valve stem one-quarter turn

counterclockwise to open. Do not overturn or the valve stem may

break or become damaged. See “PRECAUTIONS DURING

BRAZING SERVICE VALVE”.

FIGURE 4: Underground Installation

CAUTION

Dry nitrogen should always be supplied through the tubing while it is

being brazed, because the temperature required is high enough to

cause oxidation of the copper unless an inert atmosphere is provided.

The flow of dry nitrogen should continue until the joint has cooled.

Always use a pressure regulator and safety valve to insure that only

low pressure dry nitrogen is introduced into the tubing. Only a small

flow is necessary to displace air and prevent oxidation.

WARNING

This is not a backseating valve. The service access port has a valve

core. Opening or closing valve does not close service access port.

If the valve stem is backed out past the chamfered retaining wall, the

O-ring can be damaged causing leakage or system pressure could

force the valve stem out of the valve body possibly causing personal

injury.

CAUTION

Do not install any coil in a furnace which is to be operated during the

heating season without attaching the refrigerant lines to the coil. The

coil is under pressure which must be released to prevent excessive

pressure build-up and possible coil damage.

NOTICE

Line set and indoor coil can be pressurized to 250 psig with dry nitro-

gen and leak tested with a bubble type leak detector. Then release

the nitrogen charge.

Do not use the system refrigerant in the outdoor unit to purge or leak

test.

CAUTION

Do not connect manifold gauges unless trouble is suspected. Approx-

imately 3/4 ounce of refrigerant will be lost each time a standard man-

ifold gauge is connected.

SECTION IV: INDOOR EXPANSION DEVICE

THERMOSTATIC EXPANSION VALVE (TXV)

INSTALLATION

The following are the basic steps for installation. For detailed instruc-

tions, refer to the Installation Instructions accompanying the TXV kit.

Install TXV kit as follows:

1. Relieve the holding charge by depressing Schrader core on the

suction manifold stub out.

2. After holding charge is completely discharged, loosen and remove

the Schrader core.

3. Place a backup wrench on distributor, loosen and remove brass

distributor nut. Retain brass nut for use on liquid line. Keep Teflon

washer in place and discard clear disk.

4. Install the thermal expansion valve to the distributor assembly with

supplied fittings. Ensure Teflon washer is seated in distributor.

Hand tighten and turn an additional 1/4 turn to seal. Do not over-

tighten fittings. See Figure 6.

5. Slide the nut removed in step 3 over the supplied liquid line. Place

supplied Teflon washer from TXV kit in place on TXV, and install liq-

uid line to the top of the thermal expansion valve. Adjust assembly

so liquid line aligns with hole in access panel. Hand tighten the liq-

uid line, and apply an additional 1/4 turn to seal.

6. Install the TXV equalizer line onto the vapor line by hand tightening

the 1/4” SAE coupling nut to the equalizer fitting, and apply an

additional 1/3 turn to seal. See Figure 7.

7. Pass the TXV temperature sensing bulb through the suction line

split grommet in the access panel.

WARNING

Never attempt to repair any brazed connections while the system is

under pressure. Personal injury could result.

CAUTION

Outdoor unit model numbers ending with an “H” have a factory

installed hard start kit which is required when a TXV is installed on the

indoor unit. Outdoor unit model numbers with no “H” ending do not

require a hard start kit unless a TXV is being installed on the indoor

unit or unless local regulations dictate it. The Tabular Data Sheet

which comes with the unit specifies whether or not a hard start kit is

required. When a TXV Kit is needed, it should be ordered from

Source 1.

IMPORTANT: Refer to the Technical Guide for the unit to determine

the proper TXV kit to be used on this product.

CAUTION

Do not overtorque. Do not use slip joint pliers. This will distort the alu-

minum distributor and the brass fitting (potentially causing leaks).

FIGURE 6: TXV Installation

WARNING

Schrader valve core MUST NOT be installed with TXV installation.

Poor system performance or system failure could result.

FIGURE 7: TXV Bulb and Equalizer Line Installations

CAUTION

In all cases, mount the TXV bulb after vapor line is brazed and has

had sufficient time to cool. Failure to use suction line grommet may

result in premature TXV failure.

8. Install the TXV bulb to the vapor line near the cabinet, using the

bulb clamp(s) furnished with the TXV assembly. Ensure the bulb is

making maximum contact. See Figures 7 and 8.

a.If possible, install the temperature bulb on a horizontal run of the

vapor line. Ensure that the bulb is installed at a 10 o’clock or

2 o’clock position. See Figure 8.

b.If bulb installation is made on a vertical run, ensure that the bulb

is a minimum of 8 inches (20.3 cm) away from elbow coming

out of the coil. Position the bulb with the tail of the bulb at the

top, so that the bulb acts as a reservoir.

c.Insulate the bulb using thermal insulation provided to protect it

from the effect of the surrounding ambient temperature.

Cover completely to insulate.

9. After line set is installed, leak test the system.

SECTION V: EVACUATION

It will be necessary to evacuate the system to 500 microns or less. If a

leak is suspected, leak test with dry nitrogen to locate the leak. Repair

the leak and test again.

To verify that the system has no leaks, simply close the valve to the

vacuum pump suction to isolate the pump and hold the system under

vacuum. Watch the micron gauge for a few minutes. If the micron

gauge indicates a steady and continuous rise, it’s an indication of a

leak. If the gauge shows a rise, then levels off after a few minutes and

remains fairly constant, it’s an indication that the system is leak free but

still contains moisture and may require further evacuation if the reading

is above 500 microns.

SECTION VI: SYSTEM CHARGE

To ensure that your unit performs at the published levels, it is important

that the indoor airflow is determined and refrigerant charge added

accordingly.

MEASURE INDOOR AIR FLOW

To determine rated air flow for a specific match, consult the technical lit-

erature at www.upgnet.com. When attempting to match this air flow,

select the lowest possible speed tap, measure the actual flow, and

adjust as necessary.

To measure actual air flow, it is not an acceptable method to just

check the jumper pin setting tables and is to assume 0.5” water

column total external static pressure.

To determine indoor air flow, first measure the static pressure with a

manometer between the filter and return air opening of the indoor

equipment. On a single-piece or modular air handler, take a second

reading in the supply air ductwork leaving the indoor equipment. On a

gas furnace, take the second reading after the heat exchanger, but

before the indoor coil. Add the negative return static to the positive sup-

ply static to determine the system total static pressure. Treat the nega-

tive return static as a positive pressure (even though it is a negative

reading). If there is static pressure on the blower (i.e. -.10) return, add it

to a supply static (.40) which equals a (.50) total system static pressure.

Compare this value to the indoor blower performance charts ensuring

air flow is between 350 - 450 CFM per ton of cooling.

CHARGING THE UNIT

The factory charge in the outdoor unit includes enough charge for the

unit, 15 ft. (4.6 m) of refrigerant piping, and the smallest indoor coil/air

handler match-up. Some indoor coil/air handler matches may require

additional charge.

See Tabular Data Sheet provided in unit Customer Booklet for charge

requirements. The “TOTAL SYSTEM CHARGE” must be permanently

marked on the unit data plate.

TOTAL SYSTEM CHARGE DETERMINED

1. Determine outdoor unit factory charge from Tabular Data Sheet.

2. Determine indoor coil adjustment (if any) from Tabular Data Sheet.

3. Calculate the additional charge for refrigerant piping using the Tab-

ular Data Sheet if line length is greater than 15 feet (4.6 m).

4. Total system charge = item 1 + item 2 + item 3.

5. Check the unit against the pressure value listed on the cooling chart

on the unit or the appropriate heat charging chart on the following

pages of this Installation Manual. Make any adjustment necessary.

6. Add or subtract refrigerant to obtain the pressure listed on charging

chart. Make sure to adjust the total system charge by the amount

added or removed to obtain charging chart pressures. Permanently

mark the unit data plate with the total amount of refrigerant in the

system.

FIGURE 8: Proper Bulb Location

CAUTION

If a field installed device is placed in the inner-connecting refrigerant

lines that can store a significant refrigerant charge (ex: refrigerant

mass flow meter, liquid receiver, etc.) the unit may not perform as

designed. If such a performance affecting device is installed and it is

possible to check the unit in heating mode, the unit pressures should

be confirmed in heating mode. Refer to the heating charging charts

located in this installation manual.

CAUTION

Refrigerant charging should only be carried out by a licensed quali-

fied air conditioning contractor.

CHARGING WITH GAUGES

All units include a cooling charging chart for cooling. The heating

charging charts in Table 13 through Table 24 in this document use the

chart corresponding to the installed indoor coil. It can also be obtained

at www.simplygettingthejobdone.com under the Service Application

Data section.

Before using gauges, confirm that your gauges are accurate by

comparing the gauges against a calibrated pressure gauge that

has been calibrated against a national standard. If a calibrated

pressure gauge is not available, place a R-410A virgin refrigerant

container in a conditioned space long enough to come to tempera-

ture equilibrium with the surroundings. Then measure the tem-

perature of the air and the pressure of the refrigerant and compare

it to the following table:

Before measuring the pressures, use the method above to check the air

flow and then consult the table and match the liquid pressure to that air

flow.

Reference the cooling/heat charging charts in Table 4 through Table

24.

*Models do not require subcooling adjustments for approved indoor matches.

SUBCOOLING CHARGING CHARTS

CAUTION

Refrigerant charging should only be carried out by a qualified air con-

ditioning contractor.

CAUTION

Compressor damage will occur if system is improperly charged. On

new system installations, charge system per tabular data sheet for

the matched coil and follow guidelines in this instruction.

GENERAL INFORMATION & GROUNDING

The control box cover is held in place with 3 screws (one screw in each

lower corner and one screw at the top center post). The control box can

swing open by removing the screw from the center of each side of the

control box and allowing the control box to lower an inch or so into a

pivotal position.

The control box can then swing open from the left by rotating on the

right side pivots for easy service of refrigeration components. If no wir-

ing is in or routed through the control box, it can be removed from the

unit by lifting slightly, tilting the top hinge out, and lifting the bottom

hinge out. During the installation, it is recommended to route the low

voltage wiring for the thermostat along the unit high voltage wiring to

help facilitate the swing away feature of the control box. Refer to Figure

Check the electrical supply to be sure that it meets the values specified

on the unit nameplate and wiring label.

Power wiring, control (low voltage) wiring, disconnect switches and over

current protection must be supplied by the installer. Wire size should be

sized per NEC requirements.

The complete connection diagram and schematic wiring label is located

on the inside surface of the unit service access panel.

3. Replace the control box cover removed in Step 2 of the FIELD

CONNECTINS POWER WIRING procedures.

4. All field wiring to be in accordance with national electrical codes

(NEC) and/or local-city codes.

5. Mount the thermostat about 5 ft. above the floor, where it will be

exposed to normal room air circulation. Do not place it on an out-

side wall or where it is exposed to the radiant effect from exposed

glass or appliances, drafts from outside doors or supply air grilles.

6. Route the 24-volt control wiring (NEC Class 2) from the outdoor unit

to the indoor unit and thermostat.

DEHUMIDIFICATION CONTROL (Typical)

The indoor unit Installation Manual instructions for the air handler or fur-

nace describe the interface with the outdoor heat pump. A dehumidifi-

cation control accessory SI-2HU16700124 may be used with variable

speed air handlers or furnaces in high humidity areas. This control

works with the variable speed indoor unit to provide cooling at a

reduced air flow, lowering evaporator temperature and increasing latent

capacity. The humidistat in this control opens the humidistat contacts as

the humidity increases. Installation instructions are packaged with the

accessory. Prior to the installation of the dehumidification control, the

humidistat jumper must be set to ‘YES” on the indoor variable speed air

handler or furnace control board.

During cooling, if the relative humidity in the space is higher than the

desired set point of the dehumidification control, the variable speed

blower motor will operate at lower speed until the dehumidification con-

trol is satisfied. A 40-60% relative humidity level is recommended to

achieve optimum comfort.

If a dehumidification control is installed, it is recommended that a mini-

mum air flow of 325 cfm/ton be supplied at all times.

To see connection diagrams of all UPG equipment, the “Low Voltage

System Wiring” document is available online at www.upgnet.com in the

Product Catalog Section.

FIGURE 10: Outdoor Unit Control Box (208/230V Single Phase)

NOTICE

A Start Assist Kit is available and recommended for long line set

applications or in areas of known low voltage problems. The kit may

be required when a TXV is used (reference the Tabular Data Sheet to

determine if applicable).

NOTICE

INDOOR CUBIC FEET PER MINUTE (CFM) SELECTION

BOARD SETTINGS (Typical)

Refer to the indoor unit Installation Manual instructions for the air han-

dler or furnace interface with the outdoor heat pump. Refer to the Out-

door Technical Guide for the recommended indoor air flow settings of

each specific heat pump. For the system to operate correctly, ensure

that the indoor CFM Selection control jumpers are properly set. Set the

indoor cooling fan speed per the instructions for the air handler or fur-

nace by selecting the correct COOL and ADJUST (or ADJ) taps. Verify

the indoor airflow by using the LED display on the indoor CFM selection

board.

SECTION VIII: SYSTEM START-UP

ENERGIZE CRANKCASE HEATER (CCH)

In order to energize the crankcase heater, set the indoor cooling ther-

mostat to the OFF position. Close the line power disconnect to the unit.

The outdoor unit has a CCH thermostat that opens at 45°F and closes

at 35°F outdoor ambient temperature.

WITH POWER TO UNIT AND THERMOSTAT IN COOLING

POSITION:

1. In the cooling cycle, discharge gas is pumped to the outdoor coil

which is the condenser. The indoor coil is the evaporator.

2. If fan switch is in ON position, a circuit is made through the blower

relay to provide continuous blower operation.

3. With fan switch in AUTO position, a circuit is made from thermostat

cooling contact through blower relay to provide blower operation.

4. System will cycle with thermostat demand to provide cooling as

needed.

SECTION IX: SYSTEM OPERATION

ANTI SHORT-CYCLE DELAY

The control includes a five-minute anti short-cycle delay (ASCD) timer

to prevent the compressor from short-cycling after a power or thermo-

stat signal interruption. The ASCD timer is applied when the control is

first powered from the indoor unit thermostat and immediately following

the completion of a compressor run cycle. The compressor and the out-

door fan will not operate during the five minutes that the timer is active.

The ASCD timer can be bypassed by shorting the TEST terminals for

three seconds while the thermostat is calling for compressor operation

(Y input signal energized).

LOW VOLTAGE DETECTION

The control monitors the transformer secondary (24 VAC) voltage and

provides low voltage protection for the heat pump and its components.

In particular, the control prevents contactor chatter during low voltage

conditions. If the voltage drops below approximately 19 VAC, the con-

trol will continue to energize any relays that are already energized but

will not energize any additional relays until the voltage level increases.

If the voltage drops below approximately 16 VAC, the control will imme-

diately de-energize the relay outputs and will not energize any relays

until the voltage level increases.

TEST INPUT

The control includes a TEST input connector that can be used for vari-

ous testing functions during installation and service. The TEST input

connector is shown in Figure 13. The following table summarizes the

behavior of the control when the two TEST pins are connected. More

detailed descriptions of the various functions are included in other sec-

tions of this document.

NOTICE

An attempt to start the compressor without at least 8 hours of crank-

case heat may damage the compressor.

since active error codes were last cleared) starting with the most recent. If there are no error codes stored

in memory, the STATUS LED shall flash 3 times (0.1 sec ON / 0.1 sec OFF).

> 5 The control shall immediately clear the stored error code array, reset the 6 hour PS timer and flash the

STATUS LED 6 times (0.1 sec ON / 0.1 sec OFF) to indicate that the error memory has been cleared.

FAULT CODE DISPLAY

The control shall provide status codes using the LED. Status codes

indicate the state of operation of the unit but do not represent a fault.

The table below describes the LED displays during status codes. Status

codes will not be displayed when a fault code is present.

The control shall provide fault codes using the Status LED. The table

below describes the LED displays during fault codes. Unless otherwise

specified, the control shall provide flashes that are a 1/3 second on and

1/3 second off for fault codes. The control shall only display a single

fault code on the LED. The control shall display the fault code on the

LED repeatedly with a 2 second off period between repetitions of the

fault code. If multiple fault codes are present at the same time, the LED

shall display only the most recent fault.

The table below shows a number that represents the number of flashes

for the specified code. For instance, a flash code entry of 3 indicates

that the control will energize the output for three 1/3 second on, 1/3 sec-

ond off flashes, wait two seconds, then energize the output for three

more 1/3 second on, 1/3 second off flashes and repeat.

Demand Defrost

The control maintains proper airflow through the outdoor coil during

heating operation by melting frost and ice that may form on the coil.

Frost may accumulate unevenly in different sections of the coil because

of the arrangement of the refrigeration circuit within the coil. The control

may initiate a defrost cycle even when the coil is not completely cov-

ered with frost. This is normal operation.

The control regulates the defrost operation of the heat pump based on

accumulated compressor run time, outdoor coil temperature, and out-

door ambient temperature. The control will cause the heat pump unit to

operate in the normal heating mode until it determines that a defrost

cycle is needed.

All defrost timings are based on accumulated compressor run time.

Operation

The defrost mode is equivalent to the cooling mode except that the out-

door fan motor is de-energized. The control shall do the following to ini-

tiate a defrost cycle.

• De-energize the outdoor fan.

• Energize the reversing valve.

• Energize the auxiliary heat output through the Wout terminal.

• Begin the maximum defrost cycle length timer.

If the call for heating (Y) is removed from the control during the defrost

cycle, it will terminate the defrost cycle and de-energize the compres-

sor. The control will also stop the defrost cycle length timer but not reset

it. When the control receives another call for heating, it will restart the

defrost cycle and the timer at the point at which the call for heating was

removed. This will happen only if the coil sensor temperature conditions

allow defrost to occur.

Defrost Curves

The control uses a set of defrost curve parameters that are selected

using the defrost curve selection jumper. The location of the defrost

curve selection jumper is shown on the Tabular Data sheet for each

heat pump model.

Defrost Curve Selection

The second page of the tabular data sheet indicates the proper jumper

setting for the specific heat pump model.

The control only reads the jumper input when the Y and W thermostat

inputs are de-energized. If a jumper position is changed while either of

these inputs is energized, the control will not act upon the jumper

changes until the thermostat calls are de-energized or power (24 VAC)

to the control is cycled.

Defrost Cycle Initiation

The control will allow the heat pump to operate in the heating mode until

the combination of outdoor ambient and outdoor coil temperatures indi-

cate that a defrost cycle is necessary.

The control will initiate a defrost cycle when the coil temperature is

below the initiate point for the measured ambient temperature (See Fig-

ure 14) continuously for 4-1/2 minutes. This delay eliminates unneces-

sary defrost cycles caused by refrigeration surges such as those that

occur at the start of a heating cycle.

The control will initiate a defrost cycle every 6 hours (accumulated com-

pressor run time) to recirculate refrigerant lubricants. This forced

defrost timer will be reset and restarted following the completion or ter-

mination of a defrost cycle.

The control shall initiate a defrost cycle when the Defrost Inhibit Time

Limit has elapsed if the previous defrost cycle was terminated based on

the Maximum Defrost Cycle Time. This shall occur regardless of the liq-

uid line (coil) temperature reading. The coil does not have to be cold for

the unit to be forced into defrost. Once the defrost cycle begins the con-

trol shall follow the normal defrost cycle routine.

The control will also initiate a defrost cycle when the TEST terminals

are shorted. This feature allows an installer or service technician to start

a defrost cycle immediately as required. When the TEST terminals are

shorted for more than 5 seconds with a Y input energized and the pres-

sure switch input is closed, the ASCD will be bypassed, the reversing

valve will be energized, the ODF will be de-energized and the compres-

sor and the Wout terminal to auxiliary heat will be energized.

When the TEST inputs are used to force a defrost cycle, the control will

ignore the state of the coil temperature and outdoor ambient tempera-

ture inputs. The coil does not have to be cold and the outdoor tempera-

ture does not have to be within a certain range for the heat pump to be

forced into a defrost cycle. After the TEST input jumper is removed, the

defrost mode will be terminated as normal. The defrost cycle length

timer will not be started until the TEST input is removed. If the TEST ter-

minals remain shorted, the control will keep the unit in defrost mode.

Defrost Inhibition

The control will not initiate a defrost cycle if the liquid line temperature is

above 40°F unless the defrost cycle is forced using the TEST input, or

the previous defrost exited on maximum time (12 minutes).

The control will also prevent a defrost cycle from being initiated too

soon after the initiation of the previous defrost cycle. When power is

applied to the control and after the completion or termination of each

defrost cycle, the control will start a 40-minute timer. When this timer

expires, the control will allow another defrost cycle when needed. The

timer is based on accumulated compressor run time.

Defrost Termination

The control will terminate the defrost cycle immediately after the liquid

line temperature reaches the terminate temperature or after 12 minutes

of defrost operation. See Figure 14.

The control will do the following to terminate a defrost cycle:

• Energize the outdoor fan.

• De-energize the reversing valve.

• De-energize the auxiliary heat output through the Wout terminal.

• Reset and restart the 40-minute defrost inhibit timer.

COOLING OPERATION

During cooling operation, the control will receive thermostat signals at

the Y and O input terminals. The control will energize the M compressor

output terminal. This signal energizes the coil of the compressor con-

tactor causing the compressor to run. The control also delivers power to

the COND FAN terminals causing the outdoor fan to operate. The con-

trol energizes the REV VALVE terminal with 24VAC to switch the

reversing valve.

HEATING OPERATION

During normal heating mode, the control will receive a thermostat signal

at the Y input terminal. The control will energize the M compressor out-

put terminal. This signal energizes the coil of the compressor contactor

causing the compressor to run. The control also delivers power to the

COND FAN terminals causing the outdoor fan to operate. The reversing

valve is not energized in heating mode.

EMERGENCY HEAT

When the thermostat calls for emergency heat operation (W signal with-

out a Y signal), the control will de-energize the compressor and ener-

gize the Wout terminal immediately.

PRESSURE SWITCH FAULT & LOCKOUT

The heat pump is equipped with a high pressure switch and low pres-

sure switch that are connected to the control at the pressure switch ter-

minals. If one of these switches input opens for more than 40

milliseconds, the control will de-energize the compressor. If the switch

closes and a thermostat call for compressor operation is present, the

control will apply the five-minute anti short-cycle delay timer and start

the compressor when the timer expires.

When the compressor is started following a switch fault, the control will

start a six-hour timer based on accumulated compressor run time. If the

control senses another opening of the switch before the timer expires, it

will cause a soft lockout condition. The second opening of the switch

must be greater than 160 milliseconds for the lockout to occur. If the

second opening is between 40 and 160 milliseconds, the control will de-

energize the compressor but not cause a soft lockout condition. If the

control does not sense a second switch opening before the six-hour

timer expires, the timer and counter will be reset.

During the soft lockout mode, the control will de-energize the compres-

sor and energize the LED output with the appropriate flash code.

The control will reset the soft lockout condition when any of the follow-

ing occur after removal of the fault condition.

1. Power is cycled to the R or Y inputs of the control. This will cause

the soft lockout condition to be reset when the thermostat is satis-

fied or when the thermostat is set to SYSTEM OFF and back to

HEAT or COOL mode.

2. The TEST terminals are shorted for more than two seconds.

When the soft lockout condition is reset, the control will stop displaying

the fault code and will respond to thermostat inputs normally.

SECTION X: INSTRUCTING THE OWNER

Assist owner with processing warranty cards and/or online registration.

Review Owners Guide and provide a copy to the owner and guidance

on proper operation and maintenance. Instruct the owner or the opera-

tor how to start, stop and adjust temperature setting.

When applicable, instruct the owner that the compressor is equipped

with a crankcase heater to prevent the migration of refrigerant to the

compressor during the OFF cycle. The heater is energized only when

the unit is not running. If the main switch is disconnected for long peri-

ods of shut down, do not attempt to start the unit until 8 hours after the

switch has been connected. This will allow sufficient time for all liquid

refrigerant to be driven out of the compressor.

The installer should also instruct the owner on proper operation and

maintenance of all other system components.

MAINTENANCE

1. Dirt should not be allowed to accumulate on the outdoor coils or

other parts in the air circuit. Clean as often as necessary to keep

the unit clean. Use a brush, vacuum cleaner attachment, or other

suitable means.

2. The outdoor fan motor bearings are permanently lubricated and do

not require periodic oiling.

3. If the coil needs to be cleaned, it should be washed with Calgon

Coilclean (mix one part Coilclean to seven parts water). Allow solu-

tion to remain on coil for 30 minutes before rinsing with clean water.

Solution should not be permitted to come in contact with painted

surfaces.

4. Refer to the furnace or air handler instructions for filter and blower

motor maintenance.

5. The indoor coil and drain pan should be inspected and cleaned reg-

ularly to prevent odors and assure proper drainage.
