5.4 Clearances
The unit clearance from a combustible surface may be
0”. However, service clearance must take precedence. A
minimum of 24” in front of the unit for service clearance
is required. Additional clearance on one side or top will
be required for electrical wiring connections. Consult all

All cut ends are to be round, burr free, and clean. Failure
to follow this practice increases the chances for refrigerant
leaks. The suction line is spun closed and requires tubing
cutters to remove the closed end.

5. The outdoor temperature must be 60°F or higher.
6. Set the room thermostat to COOL, fan switch to
AUTO.
7. Set the temperature control well below room
temperature.
Superheat adjustments should not be made until indoor
ambient conditions have stabilized. This could take up to
24 hours depending on indoor temperature and humidity.
Before checking superheat run the unit in cooling for 10
minutes or until refrigerant pressures stabilize. Use the
following guidelines and methods to check unit operation
and ensure that the refrigerant charge is within limits.

1. Purge gauge lines. Connect service gauge manifold to
base-valve service ports.
2. Temporarily install a thermometer on the liquid
line at the liquid line service valve and 4-6” from
the compressor on the suction line. Ensure the
thermometer makes adequate contact and is insulated
for best possible readings. Use liquid line temperature
to determine subcooling and vapor temperature to
determine superheat.
3. Check subcooling and superheat. The system should
have a subcooling of 8°F +/- 1°F and two-stage
compressor systems should have a Subcooling of 6°F
+/- 1°F. and superheat of 8°F +/- 1°F. If subcooling
and superheat are low, adjust TXV to 8°F +/- 1°F
superheat, then check subcooling.
a. If subcooling is low and superheat is high,
add charge to raise subcooling to 8°F +/- 1°F.
Two-stage compressor systems should have a
Subcooling of 6°F +/- 1°F then check superheat.
b. If subcooling and superheat are high, adjust
TXV valve to 8°F +/- 1°F superheat, then check
subcooling.

1. Attach a pipe clamp thermometer near the suction line
service valve at the outdoor unit.
a. Ensure the thermometer makes adequate contact
for the best possible readings.
2. TXV-based systems should have a Superheat value of
8°F +/- 1°F.
3. Adjust Superheat by turning the TXV valve stem
clockwise to increase and counterclockwise to
decrease. Adjustments should be made opening or
closing the valve by no more than ¼ turn at a time.
Allow the system to stabilize 15 to 20 minutes before
making additional adjustments if necessary.
4. After adjustments are complete replace cap on
adjustment stem and tighten 1/6 turn.
5. Remove gauges and check the Schrader ports for
leaks and tighten valve cores if necessary. Install caps

operation thus preventing condensate from draining, and
if connected to a sewer line to prevent sewer gases from

12.1 Building Electrical Service Inspection
This unit is designed for single-phase electrical supply
only. DO NOT OPERATE ON A THREE-PHASE POWER
SUPPLY. Measure the power supply to the unit. The supply
voltage must be measured and be in agreement with the
unit nameplate power requirements and within the range
shown.
12.2 Wire Sizing
Wire size is important to the operation of your equipment.
Use the following check list when selecting the appropriate
wire size for your unit.
• Wire used must carry the Minimum Circuit Ampacity

optional electric heat kit can be found on the unit
Series and Rating Plate.
• Wire must be sized to allow no more than a 2%
voltage drop from the building breaker/fuse panel to
the unit.

Refer to the latest edition of the National Electric Code or in
Canada the Canadian Electric Code when determining the
correct wire size.

The building supply connects to the stripped black and red
wires contained in the air handler electrical compartment
cavity. A ground screw is also contained in this area.
Attach the Supply wires to the air handler conductors as
shown in the unit wiring diagram using appropriately sized
solderless connectors or other NEC or CEC approved
means.
12.4.2 Air Handler - Non-Circuit Breaker Heat Kits
A terminal block is provided with the HKS and HKTSD kit
to attach the power supply and air handler connections.
Follow the HKS and HKTSD Installation Manual and wiring
diagram for complete wiring details.
12.4.3 Air Handler With Circuit Breaker Heat Kit
The air handler has soft plastic cover on the upper access
panel and can be removed to allow the heater kit circuit
breaker to be installed. The circuit breakers have lugs
for power supply connection. See the HKS and HKTSD
Installation Instructions for further details.
12.5 Low Voltage Connections
Several combinations of low voltage schemes are possible,
depending on the presence of a heat kit and whether the
heat kit is single-stage or multi-stage, whether the outdoor
section is an air conditioner or heat pump, and whether
the outdoor section is single-stage or two-stage. The
24V-control voltage connects the air handler to the room
thermostat and condenser. Low voltage wiring must be
copper conductors. A minimum of 18AWG must be used
for installations up to 100 feet. Low voltage wiring must
be connected through the top of the cabinet or either side.
See the “Thermostat Wiring” section of this manual for
typical low voltage wiring connections.
12.5.1 Thermostats
Second-stage heat can be accomplished by a multi-stage
heating thermostat or the addition of an outdoor thermostat
as shown in wiring schematics on page 19. Follow the
thermostat manufacturer’s instructions for installation.
