INSTALLATION RECOMMENDATIONS

The GB Water-to-Air Heat Pumps are performance certified to

American Heating and Refrigeration Institute (AHRI) ISO

Standard 13256-1. All GB Water-to-Air Heat Pumps conform to

UL1995 standard and are certified to CAN/CSA C22.1 No 236 by

Intertek-ETL. The Water-to-Air Heat Pumps are designed to

operate with entering fluid temperature between 20°F to 90°F in

the heating mode and between 30°F to 120°F in the cooling mode.

Safety devices are built into each unit to provide the maximum

system protection possible when properly installed and maintained.

IMPORTANT: 50 ° Min. EWT (entering water temperature) for

well water applications with sufficient water flow to prevent

freezing. Antifreeze solution is required for all closed loop

applications. Earth Coupled (Geothermal) applications should have

sufficient antifreeze solution to protect against extreme conditions

and equipment failure. Frozen water coils are not covered under

warranty.

IMPORTANT: This product should not be used for temporarily

heating or cooling during construction. Doing so may effect the

unit's warranty.

UNIT OPERATION HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.

Discharge air configuration change is not possible on Heat

Pumps equipped with Electric Heat Option.

Check Equipment and Job Site

Movinu and Storage

If the equipment is not needed for immediate installation upon its

arrival at the job site, it should be left in its shipping carton and

stored in a clean, dry area. Units nmst only be stored or moved in

the normal upright position as indicated by the :'UP" arrows on

each carton at all times.

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage.

If unit stacking is required for storage, stack units as follows:

Do not stack units larger than 6 tons!

Vertical units: less than 6 tons, no more than two high.

Horizontals units: less than 6 tons, no more than three high.

Inspect Equipment

Be certain to inspect all cartons or crates on each unit as received at

the job site before signing the freight bill. Verify that all items have

been received and that there are no visible damages; note any

shortages or damages on all copies of the freight bill. In the event

of damage or shortage, remember that the purchaser is responsible

for filing the necessary claims with the carrier. Concealed damages

not discovered until after removing the units from the packaging

must be reported to the carrier within 24 hours of receipt.

Location /Clearance

Locate the unit in an indoor area that allows easy removal of the

filter and access panels, and has enough room for service personnel

to perform maintenance or repair. Provide sufficient room to make

fluid, electrical, and duct connection(s). If the unit is located in a

confined space such as a closet, provisions nmst be made for return

air to freely enter the space. On horizontal units, allow adequate

room below the unit for a condensate drain trap and do not locate

the unit above supply piping.

[]NIT OPERATION HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.

These units are not approved for outdoor installation;

therefore, they must be installed inside the structure being

conditioned. Do not locate in areas that are subject to

freezing.

[]NIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in equipment

damage and/or improper equipment operation.

It is extremely important to take the proper precautions to

insure that the heat pump unit is installed in the proper

location and that measures have been taken to prevent

rupturing the water coil due to freezing conditions.

Frozen water coils are not covered under the limited

product warrant,v.

APPLICATION CONSIDERATIONS

Earth Coupled (Geothermal) Systems

Closed loop and pond @plications require specialized design

knowledge. No attempt at these installations should be made unless

the dealer has received specialized training.

Well Water Systems

IMPORTANT: Table 1 must be consulted for water quality

requirements when using open loop systems. A water sample must

be obtained and tested, with the results compared to the table.

Scaling potential should be assessed using the pH/Calcium

hardness method. If the pH is <7.5 and the calcium hardness is

1<100 ppm, the potential for scaling is low. For numbers out of the

range listed, a monitoring plan must be implemented due to

probable scaling.

Other potential issues such as iron fouling, corrosion, erosion and

clogging must be considered. Careful attention to water conditions

must be exercised when considering a well water application.

Failure to perform water testing and/or applying a geothermal heat

pump to a water supply that does not fall within the accepted

quality parameters will be considered a mis-application of the unit

and resulting heat exchanger failures will not be covered under

warranty. Where a geothermal system will be used with adverse

water conditions, a suitable plate-frame heat exchanger MUST be

used to isolate the well water from the geothermal unit.

Proper testing is required to assure the well water quality is suitable

for use with water source equipment.

In conditions anticipating moderate scale formation or in brackish

water, a cupronickel heat exchanger is recommended. Copper is

adequate for ground water that is not high in mineral content.

In well water applications, water pressure must always be

maintained in the heat exchanger. This can be accomplished with

either a control valve or a bladder type expansion tank.

When well water is used exclusively for supplying water to the

heat pump, the pump should operate only when the heat pump

operates. A 24 volt double pole single throw (DP/ST) contactor

(Fig. 2) can be used to operate the well pump with the heat pump.

Pressure/temperature ports are recommended in both the supply

and return lines for system flow balancing. The water flow can be

accurately set by measuring the water-to-refrigerant heat

exchangers water side pressure drop. See the unit specification

sheets for the water flow and pressure drop information in the back

of this manual.

The discharge water from the heat pump is not contaminated in any

manner and can be disposed of in various ways depending on local

codes (i.e. discharge well, dry well, storm sewer, drain field,

stream, pond, etc.)

When using a single water well to supply both domestic water and

the heat pump care must be taken to insure that the well can

provide sufficient flow for both. In well water applications a slow

closing solenoid valve must be used to prevent water hammer.

Solenoid valves should be connected across Y and C on the

interface board for all. Make sure that the VA draw of the valve

does not exceed the contact rating of the thermostat.

Pressure/temperature ports are recommended in both supply and

return lines for system flow balancing. Water flow can be

accurately set by measuring the water-to-refrigerant heat

exchangers water side pressure drop. See specification sheets for

water flow vs. pressure drop information in the back of this

manual.

MOUNTING VERTICAL UNITS

GB Vertical units up to five tons are available in left or right air

return configurations. Vertical units should be mounted level on a

vibration absorbing pad slightly larger than the base to nfininfize

vibration transmission to the building structure. It is not necessary

to anchor the unit to the floor. See Fig. 5.

MOUNTING HORIZONTAL UNITS

While horizontal units may be installed on any level surface strong

enough to hold their weight, they are typically suspended above a

ceiling by threaded rods. The manufacturer recommends these be

attached to the unit corners by hanger bracket kits (see Fig. 6). The

rods nmst be securely anchored to the ceiling. Refer to the hanging

bracket assembly and installation instructions for details.

A14165

Fig. 6 -Hanger Bracket Kit

IMPORTANT: Horizontal units installed above the ceiling

must conform to all local codes. An auxiliary drain pan, if

required by code, should be at least four inches larger than the

bottom of the heat pump.

Plumbing connected to the heat pump must not come in direct

contact with joists, trusses, walls, etc. Some applications require an

attic floor installation of the horizontal unit. In this case, the unit

should be set in a full size secondary drain pan on top of a

vibration absorbing mesh.

The Secondary drain pan prevents possible condensate overflow or

water leakage damage to the ceiling.

The secondary drain pan is usually placed on a plywood base

isolated from the ceiling joists by additional layers of vibration

absorbing mesh.

In both cases, a 3/4"drain connected to this secondary pan should

be run to an eave at a location that will be noticeable. If the unit is

located in a crawl space, the bottom of the unit must be at least 4"

above grade to prevent flooding of the electrical parts due to heavy

rains.

A14118

Fig. 7 -Condensate Drain

A drain line nmst be connected to the heat pump and pitched away

from the unit a minimum of 1/8" per foot to allow the condensate

to flow away from the unit,

IMPORTANT: This connection must be in conformance with

local plumbing codes. A trap must be installed in the

condensate line to insure free condensate flow. Heat Pumps are

not internally trapped.

A vertical air vent is sometimes required to avoid air pockets (see

Fig. 7). The length of the trap depends on the amount of positive or

negative pressure on the drain pan. A second trap must not be

included.

The horizontal unit should be pitched approximately 1/4" towards

the drain in bot directions to facilitate condensate removal (see Fig.

8).

A14152

Fig. 8 -Horizontal []nit Pitch

DUCT SYSTEM

A supply air outlet collar and return air duct flange are provided on

all units to facilitate duct connections. Refer to the individual

Product Data for physical dimensions of collar and flange.

NOTE: Supply air duct and return air duct flanges are shipped

unfolded with unit.

A flexible connector is recommended for supply and return air duct

connections on metal duct systems. All metal ducting should be

insulated with a minimum of one inch duct insulation to avoid heat

loss or gain and prevent condensate from forming during the

cooling operation.

Application of the unit to uninsulated duct work is not

recommended as the unit's performance will be adversely affected.

UNIT OPERATION HAZARD

Failure to follow this caution may result in improper

equipment operation.

Do not connect discharge ducts directly to the blower

outlet.

The factory provided air filter must be removed when using a filter

back return air grill. The factory filter should be left in place on a

free return system.

If the unit will be installed in a new installation which includes new

duct work, the installation should be designed using current

ASHRAE procedures for duct sizing.

If the unit is to be connected to existing duct work, a check should

be made to assure that the duct system has the capacity to handle

the air required for the unit application.

If the duct system is too small, larger duct work should be installed.

Check for existing leaks and repair.

The duct system and all diffusers should be sized to handle the

designed air flow quietly. To maximize sound attenuation of the

unit blower, the supply and return air plenums should be insulated.

There should be no direct straight air path through the return air

grille into the heat pump. The return air inlet to the heat pump must

have at least one 90 degree turn away from the space return air

grille. If air noise or excessive air flow are a problem, the blower

speed can be changed to a lower speed to reduce air flow. Refer to

Table 2 for ECM motor speeds and settings.

UNIT OPERATION AND SAFETY HAZARD

Failure to follow this warning could result in personal iniury

and/or death as well as equipment damage.

Always disconnect power to the unit before changing motor

speed to prevent electrical shock and/or damage to the motor.

PIPING

Supply and return piping must be as large as the unit connections

on the heat pump (larger on long runs).

UNIT OPERATION HAZARD

Failure to follow this caution may result in improper

equipment operation.

Never use flexible hoses of a smaller inside diameter than

that of the fluid connections on the unit.

GB units are supplied with either a copper or optional cupronickel

condenser. Copper is adequate for ground water that is not high in

mineral content.

NOTE: Proper testing is recommended to assure the well water

quality is suitable for use with water source equipment. When in

doubt, use cupronickel.

In conditions anticipating moderate scale formation or in brackish

water, a cupronickel heat exchanger is recommended.

Both the supply and discharge water lines will sweat if subjected to

low water temperature. These lines should be insulated to prevent

damage from condensation.

All manual flow valves used in the system must be ball valves.

Globe and gate valves must not be used due to high pressure drop

and poor throttling characteristics.

EQUIPMENT DAMAGE

OPERATION HAZARD AND/OR UNIT

Failure to follow this caution may result in equipment

damage and/or improper operation.

Never exceed the recommended water flow rates as serious

damage or erosion of the water-to-refrigerant heat

exchanger could occur.

Improper heat exchanger water flow due to piping, valve

arrangement or improper pump operation is hazardous to

the unit and constitutes abuse which will void the heat

exchanger and compressor warranty.

Always check carefully for water leaks and repair appropriately.

[]nits are equipped with female pipe thread fittings. Consult

Product Data for sizes.

NOTE: Teflon tape sealer should be used when connecting water

piping connections to the units to insure against leaks and possible

heat exchanger fouling.

Flexible hoses should be used between the unit and the rigid

system to avoid possible vibration. Ball valves should be installed

in the supply and return lines for unit isolation and unit water flow

balancing.

No unit should be connected to the supply or return piping until

the water system has been completely cleaned and flushed to

remove any dirt, piping chips or other foreign material. Supply and

return hoses should be connected together during this process to

ensure the entire system is properly flushed. After the cleaning and

flushing has taken place the unit may be connected to the water

loop and should have all valves wide open. Do not over-tighten

connections.

Fig. 9 -Safety Device and UPM Controller

Each unit is factory provided with a Unit Protection Module

(UPM) that controls the compressor operation and monitors the

safety controls that protect the unit (see Fig. 9).

Safety controls include the following:

• High pressure switch located in the refrigerant discharge line and

wired across the HPC ternfinals on the UPM

• Low pressure switch located in the unit refrigerant suction line

and wired across ternfinals LPCI and LPC2 on the UPM.

• Freeze protection sensor, mounted close to condensing water coil

(see Fig. 10), monitors refrigerant temperature between

condensing water coil and thermal expansion valve. If

temperature drops below or remains at freeze linfit trip for 30

seconds, the controller will shut down the compressor and enter

into a soft lockout condition. The default freeze linfit trip is 26°F,

however this can be changed to 15°F by cutting the R30 resistor

located on top of DIP switch SWI.

• The condensate overflow protection sensor is located in the drain

pan of the unit and connected to the "COND" ternfinal on the

UPM board. ...............................................................i}

A14156

Fig. 10 - Freeze Protection Sensor Location

• Evaporator freeze protection sensor, mounted after the thermal

expansion device and the evaporator, monitors refrigerant

temperature between the evaporator coil and thermal expansion

valve. If temperature drops below or remains at freeze limit trip

for 30 seconds, the controller will shut down the compressor and

enter into a soft lockout condition. The default freeze limit trip is

30°F. See Fig. 11.

A14122

Fig. 11 - Evaporator Freeze Protection Sensor Location

The UPM includes the following features:

• ANTI-SHORT CYCLE TIME--5 minute delay on break timer

to prevent compressor short cycling.

• RANDOM START--Each controller has a unique random start

delay ranging from 270 to 300 seconds to reduce the chances of

multiple units simultaneously starting after initial power up or

after a power interruption, creating a large electrical spike.

• LOW PRESSURE BYPASS TIMER--If the compressor is

running and the low pressure switch opens, then the control will

keep the compressor on for 120 seconds. After 2 minutes, if the

low pressure switch remains open, the control will shut down the

compressor and enter a soft lockout. The compressor will not be

energized until the low pressure switch closes and the anti-short

cycle time delay expires. If the low pressure switch opens 2-4

times in 1 hour, the unit will enter a hard lockout and need to be

reset.

• BROWNOUT /SURGE /POWER INTERRUPTION

PROTECTION--The brownout protection in the UPM board

will shut down the compressor if the incoming power falls below

18 VAC. The compressor will remain off until the voltage goes

above 18 VAC and the anti short cycle timer (300 seconds) times

out. The unit will not go into a hard lockout.

• MALFUNCTION OUTPUT--Alarm output is Normally Open

(NO) dry contact. If24 VAC output is needed, R must be wired to

the ALR-COM terminal; 24VAC will be available on the

ALR-OUT terminal when the unit is in alarm condition. If pulse

is selected the alarm output will be pulsed. The fault output will

depend on the dip switch setting for "ALARM". If it set to

"CONST", a constant signal will be produced to indicate a fault

has occurred and the unit requires inspection to determine the type

of fault. If it is set to "PULSE", a pulse signal is produced and a

fault code is detected by a remote device indicating the fault. See

LED Fault Indication below for blink code explanations. The

remote device must have a malfunction detection capability when

the UPM board is set to "PULSE".

TEST DIP SWITCH--A test dip switch is provided to reduce all

time delay settings to 10 seconds during troubleshooting or

verification of unit operation. Note that operation of the unit while

in test mode can lead to accelerated wear and premature failure of

the unit. The "TEST" switch must be set back to "NO" for normal

operation.

FREEZE SENSOR_The freeze sensor input is active all the

time, if a freeze option is not selected the freeze terminals will

need a jumper. There are 2 configuraMe freeze points, 26°F &

15 °F. The unit will enter a soft lock out until the temperature

climbs above the set point and the anti-short cycle time delay has

expired. The freeze sensor will shut the compressor output down

after 90 seconds of water flow loss and report a freeze condition. It

is recommended to have a flow switch to prevent the unit from

running if water flow is lost.

UNIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in unit damage

and/or improper equipment operation.

If unit is employing a fresh water system (no anti-freeze

protection), it is extremely important to have the "Freeze"

jumper R30 resistor set to 26°F in order to shut down the

unit at the appropriate leaving water temperature and

protect your heat pump from freezing if a freeze sensor is

included.

• EVAPORATOR FREEZE SENSOR--Evaporator freeze

protection sensor, mounted after the thermal expansion device

and the evaporator, monitors refrigerant temperature between the

evaporator coil and thermal expansion valve. If temperature drops

below or remains at freeze limit trip for 30 seconds, the controller

will shut down the compressor and enter into a soft lockout

condition. The default freeze limit trip is 30°F.

• INTELLIGENT RESET--If a fault condition is initiated, the 5

minute delay on break time period is initiated and the unit will

restart after these delays expire. During this period the fault LED

will indicate the cause of the fault. If the fault condition still exists

or occurs 2 or 4 times (depending on 2 or 4 setting for Lockout dip

switch) before 60 minutes, the unit will go into a hard lockout and

requires a manual lockout reset. A single condensate overflow

fault will cause the unit to go into a hard lockout immediately, and

will require a manual lockout reset.

•LOCKOUT RESET--A hard lockout can be reset by turning

the unit thermostat off and then back on when the "RESET" dip

switch is set to "Y" or by shutting off unit power at the circuit

breaker when the "RESET" dip switch is set to "R".

NOTE: The blower motor will remain active during a lockout

condition.

•UPM BOARD DEFAULT SETTINGS--Your UPM board will

come from the factory with the following default settings:

-- Freeze--"Terminals not jumped" on all the time

-- Temp--26°F refrigerant temp set-point

-- Lockout--2

-- Reset--"Y"

-- Alarm--"Pulse"

-- Test--"NO"

-- Hot/Dry Alarm-- "Normally Open (NO)"

Considerations

1. Always check incoming line voltage power supply and sec-

ondary control voltage for adequacy. Transformer primaries

are dual tapped for 208 and 230 volts. Connect the appro-

priate tap to ensure a minimum of 18 volts secondary con-

trol voltage. 24 volts is ideal for best operation.

2. Long length thermostat and control wiring leads may create

voltage drop. Increase wire gauge or up-size transformers

may be required to insure minimum secondary voltage sup-

ply.

3. The following guidelines are recommended for wiring be-

tween a thermostat and the unit: 18 GA up to 60 foot, 16

GA up to 100 ft and 14 GA up to 140 ft.

4. Do not apply additional controlled devices to the control

circuit power supply without consulting the factory. Doing

so may void equipment warranties.

5. Check with all code authorities on requirements involving

condensate disposal/over flow protection criteria.

SEQUENCE OF OPERATION

Cooling Mode

Energizing the "0" terminal energizes the unit reversing valve thus

placing the unit into cooling mode. The fan motor starts when the

"G" terminal is energized.

When the thermostat calls for cooling (Y), the loop pump or

solenoid valve, if present, is energized and compressor will start.

Once the thermostat is satisfied, the compressor shuts down

accordingly and the fan ramps down to either FAN ONLY mode or

OFF over a span of 30 seconds (ECM Motors).

NOTE: A fault condition initiating a lockout will de-energize the

compressor.

Heating Mode

Heating operates in the same manner as cooling, but with the

reversing valve de-energized. The compressor will run until the

desired setpoint temperature on the thermostat is achieved.

Once the thermostat is satisfied, the compressor shuts down and the

fan ramps down in either FAN ONLY mode or turns off over a

span of 30 seconds. Auxiliary electric heating coils are not

available on the GB units.

Fig. 13 - Heat Recovery Package

A14157

HEAT RECOVERY PACKAGE

The Heat Recovery package is afactory mounted option. It

consists of aforced pumped unit that employs a circulating pump

to move water through a double wall/vented heat exchanger and

returns the heated water to the water tank. The water is heated by

superheated refrigerant discharge gas from the compressor. This

waste heat of the cooling mode, captured by the heat recovery,

increases the capacity and efficiency of the heat pump unit. If the

air temperature is uncomfortable coming from the air vents in

heating mode the heat recovery may need to be turned off. In

heating mode, the heat recovery captures heat that would normally

be used for space heating.

UNIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in unit damage

and/or improper equipment operation.

If heat recovery unit is installed in an area where freezing

may occur, the unit must be drained during winter months

to prevent heat exchanger damage. Heat exchanger

ruptures that occur due to freezing will void the heat

recovery package warranty along with the heat pump

warranty.

Water Tank Preparation

1. Turn off electrical or fuel supply to the water heater.

2. Attach garden hose to water tank drain connection and run

other end of hose out doors or to an open drain.

3. Close cold water inlet valve to water heater tank.

4. Drain tank by opening drain valve on the bottom of the

tank, then open pressure relief valve or hot water faucet.

5. Once drained the tank should be flushed with cold water

until the water leaving the drain hose is clear and free of

sediment.

6. Close all valves and remove the drain hose,

HR Water Piping

All hot water piping MUST be aminimum of 3/8" O.D. copper

tube to a maximum distance of 15 feet. For distances beyond 15

feet, but not exceeding 60 feet, use 1/2" copper tube. Separately

insulate all exposed surface of both connecting water lines with

3/8" wall closed cell insulation. Install isolation valves on supply

and return to the heat recovery. (See Fig. 13)

Water Tank Refill

1. Open the cold water supply to the tank.

2. Open a hot water faucet to vent air from the system until

water flows from the faucet, then close.

3. Depress the hot water tank pressure relief valve handle to

ensure there is no air remaining in the tank.

4. Carefully inspect all plumbing for water leaks. Correct as

required.

5. Purge all air from HRP by depressing the Schrader valve on

the HR unit. Allow all air to bleed out until water appears at

the valve.

IMPORTANT: All piping from HRP to domestic water tank

must be copper or any metal of stronger alloy.

6. Before restoring the power or fuel supply to the water

heater, adjust the temperature setting on the tank

thermostat(s) to ensure maximum utilization of heat

available from the refrigeration system and to conserve the

most energy.

On tanks with thermostats and both upper and lower ele-

ments, the lower element should be turned down to 100°F,

while the upper element should be adjusted to 120°F. De-

pending upon the specific needs of the customer, you may

need to adjust the upper element differently.

On tanks with a single thermostat, lower the thermostat

setting to 120°F or the "LOW" position.

7. After thermostat adjustments are completed, replace access

cover and restore electrical or fuel supply to water heater.

7. Install HR water piping.

INITIAL START-UP

UNIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in unit damage

and/or improper equipment operation.

Make sure all valves in heat recovery water piping system

are open. NEVER OPERATE HR PUMP DRY.

1. Turn on the heat pump. The HR pump should not run if the

compressor is not running.

2. Turn HR switch to the "ON" position. The pump will

operate if entering water temperature to HR is below 120 ° F.

3. The temperature difference between the water entering and

leaving the heat recovery should be 5°F to 15°F.

4. Allow the unit to operate for 20 to 30 minutes to ensure it is

functioning properly. The pump should shut off when the

water temperature entering the heat recovery reaches 120°F.

SYSTEM CHECKOUT

After completing the installation, and before energizing the unit,

the following system checks should be made:

1. Verify that the supply voltage to the heat pump is in accor-

dance with the nameplate ratings.

2. Make sure that all electrical connections are tight and se-

cure.

3. Check the electrical fusing and wiring for the correct size.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Ensure cabinet and electrical box are properly grounded

4. Verify that the low voltage wiring between the thermostat

and the unit is correct.

5. Verify that the water piping is complete and correct.

6. Check that the water flow is correct, and adjust if necessary.

7. Check the blower for free rotation, and that it is secured to

the shaft.

8. Verify that vibration isolation has been provided.

9. Unit is serviceable. Be certain that all access panels are

secured in place.

10. Verify that blower support has been removed.

11. Verify that ductwork has been properly fastened to supply

and return duct collars.

12. Make sure return air filters are positioned correctly in the

filter rack.

UNIT START-UP

NOTE: A unit Start-Up checklist is included in the unit packet.

Complete the Checklist and place it in the customer file at your

dealership.

1. Set the thermostat to the highest setting.

2. Set the thermostat system switch to "COOL", and the fan

switch to the "AUTO" position. The reversing valve

solenoid should energize. The compressor and fan should

not run.

3. Reduce the thermostat setting approximately 5 degrees

below room temperature.

4. Verify the heat pump is operating in the cooling mode.

5. Turn the thermostat system switch to the "OFF" position.

The unit should stop running and the reversing valve should

de-energize.

6. Leave the unit off for approximately five (5) minutes to

allow for system equalization.

7. Turn the thermostat to the lowest setting.

8. Set the thermostat switch to "HEAT".

9. Increase the thermostat setting approximately five (5)

degrees above room temperature.

10. Verify the heat pump is operating in the heating mode.

11. Set the thermostat to maintain desired space temperature.

12. Check for vibrations, leaks, etc.

MAINTENANCE

1. Filter changes or cleanings are required at regular intervals.

The time period between filter changes will depend upon

type of environment the equipment is used in.

In a single family home, that is not under construction,

changing or cleaning the filter every 60 days is sufficient. In

other applications such as motels, where daily vacuuming

produces a large amount of lint, filter changes may need to

be as frequent as biweekly.

NOTE: Horizontal units containing two filters are taped together

at the factory to facilitate removal. This should be done by end user

as new filters are installed.

UNIT DAMAGE AND/OR OPERATION HAZARD

Failure to follow this caution may result in unit damage

and/or improper equipment operation.

Equipment should never be used during construction due

to likelihood of wall board dust accumulation in the air

coil of the equipment which permanently affects the

performance and may shorten the life of the equipment.

2. An annual "checkup" is recommended by a licensed

refrigeration mechanic. Recording the performance

measurements of volts, amps, and water temperature

differences (both heating and cooling) is recommended.

This data should be compared to the information on the

unit's data plate and the data taken at the original startup of

the equipment.

3. Lubrication of the blower motor is not required, however

may be performed on some motors to extend motor life.

Use SAE-20 non-detergent electric motor oil.

4. The condensate drain should be checked annually by

cleaning and flushing to insure proper drainage.

5. Periodic lockouts are commonly caused by air or water flow

problems. The lockout (shutdown) of the unit is a normal

protective measure in the design of the equipment. If contin-

ual lockouts occur, call a mechanic immediately and have

them check for the following:

- Water flow problems

- Water temperature problems

- Air flow problems

- Air temperature problems.

Use of the pressure and temperature charts for the unit may

be required to properly determine the cause.

TROUBLESHOOTING

Ent re un t Power Supply Off Apply power, close disconnect

" Vo tage Supp y Low If voltage is below m nimum voltage specified on unit data plate

' contact local power company.

Thermostat Set the fan to "ON" the fan should run. Set thermostat to "COOL'

and owest temperature setting the unit should run in the cooling

mode (reversing valve energized). Set unit to "HEAT" and the highest

temperature setting, the unit shou d run in the heating mode (reversing

valve deenergized).

If neither the blower or compressor run in all three cases the

thermostat Could be miswired or faulty. To ensure miswired or faulty

thermostat verify that 24 volts is available at the low voltage terminal

strip between 'R" and C' 'Y" and "C" and "O" and "C". If the blower

does not operate verify 24 volts between terminals "G" and 'C".
