Proximity to Evaporator
Locating the condenser as close as possible to the evaporator
will increase the system capacities by reducing the line set
refrigerant pressure drop, and will make the system less
susceptible to liquid migrations due to less refrigerant charge.
INSTALLATION
Condensing Unit Location
The condensing unit should be located outdoors as close as
possible to the evaporator. Consider the following factors:
Clearances
Electrical Connections
The air inlet should be located at least 12" from a wall or other
obstruction for unrestricted air flow.
WARNING
The air outlet should be located so as to direct discharged air
away from the building. Three feet of clearance around the
unit and a minimum of six feet clearance above the unit is
required to avoid recirculation of condenser discharge air on
vertical discharge models. Avoid locating unit under low
overhanging roofs.
BEFORE PERFORMING ANY WORK ON THIS EQUIPMENT,
POWER SUPPLY MUST BE TURNED OFF AT THE HOUSEHOLD
SERVICE BOX TO AVOID THE POSSIBILITY OF SHOCK,
INJURY, DEATH OR DAMAGE TO EQUIPMENT.

Rooftop installation is acceptable in areas of low snow
accumulations, provided the roof will support the unit and
provisions are made for water drainage and the noise or
vibration through the structure.
1. The installer shall check available power to make certain it
matches the unit rating plate (located inside control box
cover) and that constant voltage can be maintained to the
unit. Unsatisfactory performance would otherwise result.
The local power company should be contacted regarding
any problems or questions concerning power supply.
Exposure
If practical, unit should be located on the south side of the
structure away from northerly winds to minimize the effects of
blowing snowdrifts and freezing rain. A wind screen or wind
block can also be used.

Electrical Connections (cont.)
Evacuation
Connect control wiring
The outdoor unit is factory charged. Evacuation is necessary
on the uncharged portions of the total system. Purge the
system with dry nitrogen. Then connect a vacuum pump and
a vacuum gage capable of accurately measuring below
1,000 microns vacuum depth. The deep vacuum method is
the most positive way of assuring a system is free of air and
liquid water.
1. Route 24 volt control wires through control wiring grommet
and connect leads to control wiring.
2. Use No. 18 AWG color coded, insulated wire. If thermostat is
located more than 100 ft. from unit, as measured along the
control voltage wires, use No. 16 AWG wire to avoid
excessive voltage drop.
3. All wiring must be NEC Class 1 and must be separated from
incoming power leads. Use furnace transformer, fan coil
transformer, or accessory transformer for control power.
WARNING
Note: Use of available 24 volt accessories may exceed the
minimum power requirement. Determine total transformer
load and increase the transformer capacity or split the load
with an accessory transformer as required.
IF THE INSTALLER IS MAKING UP HIS OWN LINE SETS,
HE MUST MAKE SURE THE TUBING IS CLEAN OF ANY
IMPURITIES OR MOISTURE.
Opening the Service Valve (Step Valve)
Final Wiring Check
NOTE: This is not a back-seating valve.
Check factory wiring and field wire connections to ensure
terminations are secured properly. Check wire routing to
ensure wires are not in contact with tubing, sheet metal, etc.
1. Remove the valve cap using an adjustable wrench.
2. Open the valve by inserting a hex wrench (3/16" for the
liquid line, 5/16" for the vapor line) into the stem and back
out counter-clockwise until the valve stem just touches the
retaining ring. Do not over tighten.
SERVICE VALVE CONNECTIONS
Braze Joints
1. Remove the valve core from the schrader port. Wrap a
quenching cloth around the service valve. Clean and flux the
joint and braze with brazing rod containing at least 10%
silver (such as silphos type brazing rod). DO NOT USE SOFT
SOLDER. Replace the schrader valve core after brazing has cooled.
3. Replace the valve cap finger-tight, then tighten an
additional 1/12 turn or 1/2 hex flat. A metal-to-metal seal is
now complete.

Precautions
CONNECT REFRIGERANT PIPING
Refer to the chart below for the minimum recommended tube
outside diameter sizes on liquid and suction lines. Ensure that
vapor and liquid tube diameters are appropriate for unit
capacity. Run refrigerant tubes as directly as possible by
avoiding unnecessary turns and bends.
The following should be followed when installing refrigerant
piping. Comply with all local, state, and federal codes and/or
regulations pertaining to this type of equipment and its
installation.
1.
Run the tubing by the most direct route and support
every few feet. Do not run the lines underground unless
they are in a chase. Leave enough material between
structure and unit to absorb vibration.
2.
Insulate the vapor line to prevent sweating and line loss.
In underground chases, the vapor line should be
insulated to provide vibration isolation between the
vapor and liquid line. A minimum of 3/8” insulation is
recommended in conditioned space and 1/2” to 3/4” in
unconditioned space. Ensure that tubing insulation is
pliable and completely surrounds vapor tube.
3.
• Undersized line sets will increase the refrigerant pressure
drop between the indoor evaporator and outdoor unit,
resulting in a decrease in system capacity. Oversizing the line
sets may result in excessive refrigerant charge, thereby
making the system more susceptible to liquid migration.
• When passing refrigerant tubes through the wall, seal
opening with RTV or other pliable silicon based caulk
• Avoid direct tubing contact with water pipes, duct work,
floor joists, wall studs, floors, and walls
• Do not suspend refrigerant tubing from joists and studs with
a rigid wire or strap which comes in direct contact with
tubing
In general, the piping should be sloped toward the
outdoor unit to prevent oil trapping. Where vertical
risers occur, a suction line trap should be located at the
base of the riser to assure proper oil return.
• When necessary, use hanger straps which are 1 in. wide and
conform to shape of tubing insulation
• Isolate hanger straps from insulation by using metal sleeves
bent to conform to shape of insulation
WARNING
• Condensing units are available with pre-charged, sweat-type
copper connecting fittings
REFRIGERANT LINE LENGTH MUST NOT EXCEED 75’ ON
HORIZONTAL RUNS AND 40’ ON VERTICAL RISERS.

SUB-COOLING CHARGING
FINAL CHECKS FOR INSTALLER
For proper sub-cooling readings, a standard high side gauge is
required for pressure readings.
Use the charts below to determine the required sub-cooling value.
INSTRUCTIONS
1. Measure the outdoor air temperature. (T1)
2. Measure the liquid line pressure and determine the liquid
refrigerant temperature by the scale on the high side
pressure gauge. (T2) In cooling mode take reading at the
indoor coil before TXV. In heating mode take reading at the
liquid line service valve on outdoor unit.
3. Measure the liquid line temperature on the liquid line. (T3) In
cooling mode take reading at the indoor coil before TXV. In
heating mode take reading at the liquid line service valve on
outdoor unit.
4. Subtract T3 from T2. (T2 – T3) This is the subcooling value.
Compare this value and the outdoor temperature (T1), to the
charts below. If the value is below the line, add refrigerant. If
the value is above the line, remove refrigerant charge. When
removing refrigerant, always use standard reclaim procedures.
Adjusting TXV
For the majority of installations no adjustment to the TXV
setting is required. However, if the measured superheat at the
indoor coil is less than 4° or greater than 8° an adjustment is
required. The adjustment stem is at the base of the valve under
the flare nut. To increase superheat, tighten the stem clockwise
and to decrease superheat, back-out the stem counterclockwise. Use a 1/4” refrigeration service wrench for this
function.
1. Ensure that all wiring is routed away from tubing and sheet
metal edges to prevent rub-through or wire pinching.
2. Ensure that all wiring and tubing is secure in unit before
adding panels and covers.
3. Tighten service valve stem caps to 1/12 turn past
finger tight.
4. Leave this manual with owner. Explain system operation
and periodic maintenance requirements outlined in manual.
COOLING OPERATION
Turn the thermostat heat/cool switch to the cool position.
Set the desired temperature on the thermostat dial. Do not
operate the cooling unit for extended periods at indoor
temperatures over 85°F. The unit indoor design temperature
range is between 70°F and 80°F in the cooling mode.
It is not recommended to vary the temperature settings
more than 5°F. Varying the temperature more than 5
degrees or turning the thermostat off for periods less than
12 hours can actually cost you more in energy consumption
than keeping the temperature constant. Consider indoor
plants and pets when varying the temperature from the
normal comfort level.
HEATING OPERATION
Turn the thermostat heat/cool switch to the heat position.
Set the desired temperature on the thermostat dial. Do not
operate the heating unit at indoor temperatures over 80°F.
The unit indoor design temperature range is between 65°F
and 80°F in the heating mode.
11
9 SUB-COOLING CHARTS FOR UNITS WITH TXV
Never operate the unit in the cooling mode at outdoor
temperatures below 60°F without a low ambient control.
Never operate the unit in the heating mode at outdoor
temperatures above 70°F.

Auxiliary heat
10
Most heat pump installations include electric resistance heat
for auxiliary heat (when the outdoor temperature is too low
for the heat pump to provide enough heat) and for
emergency heat (the outdoor unit is not working). On a
properly-sized installation the heat pump will supply all the
heat needed during cool weather. As the temperature drops,
the heat output from the heat pump will be reduced. The
auxiliary heat installed in the system will come on as needed
to make up for this reduction of heat output.

OUTDOOR TEMPERATURE °F (T1)
The need for auxiliary heat is detected by the thermostat. If
the thermostat senses a temperature fall of more than 2°F
below the set point, the auxiliary heat will turn on. For this
reason, setting the thermostat to the desired temperature
and not changing the temperature during the day can be
more economical than varying the thermostat setting.

If it is intended to set the temperature back at night,
consider that, when the temperature is turned back up to
the normal setting, the system will be operating during the

OUTDOOR TEMPERATURE °F (T1)
All values are for reference only and may vary up or down.
All heating values are with frost-free outdoor coil. When the
outdoor temperature is below 40°F manually defrost the
unit before reading.

DEFROST OPERATION
MAINTENANCE INSTRUCTIONS
The heat pump has a control system designed to defrost the
outdoor coil by warming it up to keep it clear of ice and
operating efficiently. When the temperature drops below 40°F,
the control system will sense that conditions are right for the
formation of ice. After a time period of 60 to 90 minutes, the
heat pump will go into the defrost mode. At this time, the
outdoor coil may be heavily iced or no ice may be visible,
depending on the outdoor humidity. When the unit starts the
defrost mode, the outdoor fan will turn off and a hissing noise
may be heard that disappears as defrost continues. As the
outdoor coil warms, you may notice steam coming off the coil.
When the coil reaches a predetermined temperature (usually
within 7 minutes), the defrost cycle will end. You may hear a
hiss as the unit switches back to the normal heating mode.
For continuing high performance and to minimize possible
equipment failure, periodic maintenance must be performed on
this equipment. Frequency of maintenance may vary depending
upon geographic areas, such as coastal applications.
WARNING
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.
1. Keep the outdoor unit clean. Wash it down with a garden
hose if necessary.
WARNING
SERIOUS PERSONAL INJURY OR DEATH MAY RESULT IF
WATER SPRAY IS DIRECTED TOWARD LIVE ELECTRICAL
CONNECTIONS OR POWER SOURCES.
CAUTION
Wait at least 3 minutes after turning the heat pump off
before trying to restart. If an attempt is made to start the
compressor before the refrigerant pressures are equalized,
the unit may fail to restart. An additional waiting period will
then be required before restarting.
2. Remove any loose grass, leaves, papers, etc., from the area
around the condenser coil. These could reduce the air supply
through the coil and reduce the amount of cooling.
3. Always install and keep system filters clean. Consult your
licensed Contractor for filter replacement schedules and
instructions.
