SECTION 2. MEETING CODES
Before installing this equipment, make sure you know
all applicable codes. Installation shall be made in
accordance with the applicable National Electric Code,
local codes and recommendations made by the National
Board of Fire Underwriters, or authorities having
jurisdiction.
Electrical wiring must conform with local building codes
or in the absence of local codes, with the current National
Electrical Code, ANSI/NFPA 70 and/or current Canadian
Electrical Code, CSA C22.1.
WARNING: The United States Environmental
Protection Agency (EPA) has issued various regulations
regarding the introduction and disposal of refrigerants in this unit.
Failure to follow these regulations may harm the environment
and can lead to the imposition of substantial nes. Because
regulations may vary due to passage of new laws, we suggest a
certied technician perform any work done on this unit. Should
you have any questions please contact the local ofce of the
EPA.
SECTION 3. DETERMINING CONDENSER
LOCATION
Several important factors must be considered before
selecting the site for the outdoor unit:
• Distance to indoor coil
• Ability to service
• Proximity to the structure
• Proximity to vents and exhaust systems
• Air circulation
• Sound transmission
• Wind direction
• Relationship between structure, sun, and unit
• Distance from power source
• Water drainage
• Local codes
Locating the condenser as close as possible to the evaporator
will avoid lengthy refrigeration line runs and will increase
the system capacities. Do not locate the outdoor unit so it
discharges air under eaves or gutters. Rain or snow melt-off
should not be able to run off a roof and down upon the unit.
Be sure vents are not located upwind from the outdoor unit.
Installer’s Information Manual Page 3

A minimum clearance of 18” is required for service at
the control panel access. A 12” clearance is required
for the air inlet to the outdoor coil around the perimeter
of the unit. The air discharge of the unit requires a 60”
clearance between the top of the unit and any obstruction.
See Pictorial below.
The length of the refrigerant tubing, between the outdoor
unit and indoor coil, should be as short as possible to
avoid capacity and efciency loss. Excessive spacing of
the outdoor unit from the home can lead to the refrigerant
lines being restricted by trampling or by being punctured
by lawn mowers. Locate the outdoor unit away from
bedroom windows or other rooms where sound might
not be desirable.
Provide sufcient clearance from shrubs to allow adequate
air to pass across the outdoor coil without leaves or branches
being pulled into the coil.
Consideration should be given to the distance and routing of
electrical service that would have to be run to connect the
outdoor unit.
The outdoor 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. Isolate the base from the structure
to avoid noise or vibration transmission. When installing
units on a roof, a structure should be used to minimize the
transmission of sound or vibration into the conditioned space.
Thought should be give to water drainage away from the
outdoor unit. Drain holes in the base pan must be kept clear.
SECTION 4. REFRIGERANT PIPING
CONNECTIONS
Undersized line sets will increase the refrigerant pressure
drop between the indoor evaporator and outdoor unit,
resulting in a decrease in system capacity. Over sizing
the line sets may result in excessive refrigerant charge,
thereby making the system more susceptible to liquid
migration. Slope horizontal vapor lines at least 1” every
20 feet toward the outdoor unit to facilitate proper oil
return.
Use only refrigerant grade (dehydrated and sealed)
copper tubing of the size indicated in Table 1 to
interconnect the condensing unit with the indoor
evaporator. Take extreme care to keep refrigerant
tubing clean and dry prior to and during installation.
All outdoor unit and evaporator coil connections are copper to
copper and should be brazed with a copper alloy material such
as Silfos-5 or equivalent instead of soft solder. The outdoor
units have re-usable service valves on both the liquid and
vapor connections. Precautions should be taken to prevent
heat damage to the valve by wrapping a wet rag around it
when brazing. Do not remove plugs from ends of tubing
until connection is ready to be made. Suction line insulation
is necessary to prevent condensation from forming on and
dropping from suction line. Apply suction line insulation by
sliding it on the sealed tubing before cutting and making
connections. See Table 1 for correct vapor line size.

Table 2. Electrical Specications
BRAZING JOINTS
1. Remove the valve core from the Schrader port. Wrap
a wet rag around the valve body and copper stub
before brazing.
2. Flux the copper tube and the stub with silphos rod
containing at least 10% silver. Braze the joint, and then
use a second wet rag to cool joint before removing rst
rag wrapped around service valve.
3. Replace the valve core to the Schrader port.
4. All joints and ttings must be properly leak
tested at all braze joints as per EPA guidelines.
NOTE: Do not use air to leak test braze joints. Dry
nitrogen should be used.
5. Purge and evacuate the lines to 29.96” Hg (1000
microns) or lower when all joints and ttings are leak
free.
6. This is not a back-seating valve. To open the valve cap,
use an adjustable wrench. To open the valve, insert an
adjustable wrench. To open the valve, insert a hex
wrench (3/16” for the liquid line, 5/16” for the vapor
line) into the stem and back out counterclockwise until
the valve stem just touches the retaining ring. Do not
over tighten. This opens the valve completely. The
gauge port is (open) accessible at all times.
CAUTION: Extreme care should be used
when brazing joints. Keep torch away from condenser
cabinet, aluminum coil and plastic top.
WARNING: If the valve stem is backed out
past the retaining ring, system pressure could force the
valve stem out of valve body and possibly cause personal
injury. In the event the retaining ring is missing, do not
attempt to open the valve.
7. Replace the valve cap nger-tight, then tighten an additional
1/12” turn or 1/2” hex at. A metal-to-metal seal is now
complete.
SECTION 5. ELECTRICAL CONNECTION
1. The installer shall check available power to make certain it
matches the unit (Name Plate Rating) and that constant voltage
can be maintained to the unit. Unsatisfactory performance
would otherwise result. The local power company should be
contacted on any problems or questions concerning power
supply.
2. Install a line service disconnect switch within sight of the
condensing unit. The line voltage service wiring for the
condensing unit should include a fused disconnect switch.
3. Use correct wire size and fuse size. To ensure that adequate
voltage will be available at the condensing unit, the line
voltage service wiring MUST be of adequate size. Minimum
recommended wire ampacities and maximum fuse sizes are
listed on the unit name plate (See also Table 2).
4. Two holes are provided in the control box.
• One is for the connection of the line voltage
conduit or cable. The hole is sized for 1 1/8” conduit.
• One is for low-voltage wiring. (Refer to the
wiring diagram attached to the electrical box
cover for connection)
5. Be sure to ground the condensing unit by securing the ground
wire to the grounding lug inside the control box.
6. Be sure to follow National Electrical Code and all local codes.
NOTE: Use copper conductors only.
WARNING: Electrical equipment should be
installed by a qualied, licensed electrician. Disconnect
all power to the unit before installing or servicing. Failure
to follow this warning may result in property damage,
personal injury or death due to electrical shock.

WARNING: Casing or cabinet must be
permanently grounded in accordance with National
Electric Code or other applicable local codes.
SECTION 6. REFRIGERANT CHARGE
MEASUREMENT
If a calibrated charging cylinder or accurate weighing
device is available, add refrigerant accordingly.
FIELD CHARGING
Depending on the type of restricting device that is
installed on the system (TXV, piston, capillary tubes,
etc.), the sub-cooling or superheat charging method
can be used for eld charging or checking the existing
refrigerant charge in a system. Because each installation
is different in terms of indoor air ow, refrigerant line
length, and duct variations, etc., the factory charge may
not be correct for every application. To assure the best
performance from the air conditioner, the refrigerant
charge should be checked and adjusted when needed
on each installation.
CAUTION: Refrigerant charging
should only be carried out by a qualied air
conditioning contractor.
CAUTION: Compressor damage will occur
if system is improperly charged. On new system
installations, charge the system per refrigerant charge
information label and follow guidelines in these
instructions.
WARNING: Refrigerant is under pressure.
Guard against refrigerant spraying into the face or on skin.
Always wear protective equipment, i.e. safety glasses or
goggles and gloves when working with refrigerant.
SUB-COOLING CHARGING METHOD
The sub-cooling charging method is to be used on units
which have Thermostatic Expansion Valve (TXV) as the
expansion device. For proper sub-cooling readings, a
standard high side gauge is required for pressure readings.
1. Measure the outdoor air temperature. (T1)
2. Measure the liquid line pressure at the outdoor unit and
determine condenser refrigerant temperature by the scale
on the high side pressure gauge. (T2)
3. Measure the liquid line temperature on the liquid line at the
outdoor unit. (T3)
4. Subtract T3 from T2. (T2 - T3). This is the sub-cooling value.
Compare this value and the outdoor temperature (T1), to the
chart on page 8 (Figure 3). If the value is below the line, add
refrigerant. If the value is above the line, remove refrigerant
charge.
NOTE: When removing refrigerant, always use standard
reclaim procedures.
NOTE: On cooler days (65°F or lower), attempts to
operate the air conditioner and take gauged pressure
readings may be unsuccessful, as unusually low pressures
will be observed on the suction line. This type of operation
may give the impression of an undercharged unit. Such
is NOT necessarily the case. The low-pressure reading
may exist because of the large condenser surface area
and the cold ambient air removing so much heat from the
refrigerant. Sub-cooling occurs and results in very low
pressures. Adding refrigerant in cold weather will result
in an overcharged unit, which may then trip out on high
pressure limit during warm or hot weather. Line pressures
should not be taken for test purposes when the outdoor
temperature is below 70°F since a false reading may occur.
Do not attempt to operate the air conditioner on a day of
45°F or cooler.

SECTION 7. CHECKOUT PROCEDURE
CHECKOUT PROCEDURE
Use the following list to see that nothing was over looked:
1. Have all braze joints on refrigerant lines been leak checked?
2. Line set ttings leak checked?
3. Have base valves been opened?
4. Have all refrigerant lines been secured and isolated
properly?
5. Is the indoor coil drain hooked up and draining freely?
Pour water in drain pan.
6. Is air lter installed and clean?
7. Is the blower motor speed set correctly?
NOTE: Installer should place unit data sheet and
installation instruction in customer packet and give to
home owner after installation is complete.
SYSTEM OPERATION CHECKOUT
1. With thermostat set to the OFF position, close disconnect
switch or switches to complete circuits to condensing unit
and furnace. Set thermostat to call for cooling.
2. After the system starts, check the voltage and amperage at
the condensing unit contractor.
3. If voltage is not within 10% of rated voltage, or amperage
greatly exceeds nameplate amperage, shut down the
system and contact the local power company for corrections;
otherwise unsatisfactory performance may result.
4. With the system in operation, check the condensing unit for
unusual noise and undue vibration.
5. Allow the system to operate until it is balanced or stabilized
(approximately 30 minutes), before making further checks.
6. Remove manifold gauge hoses, and install cap on Schrader
valves.
Installer’s Information Manual Page 7
SECTION 8. MAINTENANCE
The following maintenance points should be reviewed
annually:
INDOOR
• The evaporator coil should be inspected for blockages
• Vacuum or spray the coil ns with water to remove
dust and dirt.
OUTDOOR
• Remove leaf or debris blockage from the condenser.
• Clean the condenser coil by spraying it with clean
water from a garden hose.
• Spray water from inside of the coil outward. Avoid
wetting any electrical controls.
NOTE: Change air lters monthly to keep the airow path
clean.
If unit is not operating properly, check the following items:
• The indoor section for dirty lter and outdoor section
for leaf or debris blockage.
• If the compressor has shutdown on thermal-overload
due to dirty lter or blockage, it may be necessary to
wait 2 hours to cool before the unit will restart.
• If the temperature setting on the thermostat is low
enough to bring the air conditioner on and system still
does not start, call a service technician.
CAUTION: Be sure the unit disconnect is in
the OFF position and that all electrical power to the unit is
turned off before cleaning the system.
