OPERATING INSTRUCTIONS
NOTE: Thermostat styles vary. Some models may not include
the AUTO mode and others will have the AUTO in place of the
HEAT and COOL. Others may include all three. Please refer
to the thermostat manufacturer’s User manual for detailed
programming instructions.
Cooling Operation
1. Set the thermostat’s system mode to COOL or AUTO and
change the fan mode to AUTO. See Figure 1
2. Setthetemperatureselectortothedesiredtemperaturelevel.
The outdoor fan, compressor, and blower motor will all cycle
on and off to maintain the indoor temperature at the desired
cooling level.
NOTE: If the temperature level is re-adjusted, or the system
mode is reset, the fan and compressor in the outdoor unit
may not start immediately. A protective timer circuit holds the
compressorandtheoutdoorfanoffforapproximately5minutes
following a previous operation or the interruption of the main
electrical power.
Heating Operation
1. Set the thermostat’s system mode to HEAT or AUTO and
change the fan mode to AUTO. See Figure 1.
2. Setthetemperatureselectortothedesiredtemperaturelevel.
The optional heating equipment (furnace or electric heat)
will cycle on & off to maintain the indoor temperature at the
desired heating level.

Unbalanced 3-Phase Supply Voltage
Voltageunbalanceoccurswhenthevoltagesofallphases
of a 3-phase power supply are no longer equal. This
unbalance reduces motor efficiency and performance.
Some underlying causes of voltage unbalance may
include: Lack of symmetry in transmission lines, large
single-phase loads, and unbalanced or overloaded
transformers. A motor should never be operated when a
phase imbalance in supply is greater than 2%.
Perform the following steps to determine the percentage
of voltage imbalance:
1.Measurethelinevoltages
of your 3 phase power
supplywhereitentersthe
buildingandat alocation
thatwillonlybededicated
to the unit installation (at

In this example, the measured line voltages were
236,240,and237.Theaveragewouldbe228volts
(236 + 240 + 237 = 713 / 3 = 238).
The amount of phase imbalance (0.84%) is satisfactory
since the amount is lower than the maximum allowable
2%. Please contact your local electric utility company if
your voltage imbalance is more than 2%.
Example:
Fromthevaluesgiven instep 1,theBCvoltage
(240V) is the greatest difference in value from

the fan mode should be set to AUTO. Close all electrical
disconnects to energize the system.
Air Circulation - Indoor Blower
1.Set the thermostat system mode on OFF and the fan
mode to ON.
2.Verifytheblowerrunscontinuously.Checktheairdelivery
at the supply registers and adjust register openings for
balanced air distribution. If insufficient air is detected,
examine ductwork for leaks or obstructions.
3.Set the thermostat fan mode to AUTO and verify the
blower stops running.
NOTE: On 3 phase air handler models only - If blower

power to the unit and switch any two field wires at the
disconnect. DO NOT alter unit wiring.
Anti-Short Cycle Timer Protection
(Single Phase Models Only)
1.Set the thermostat system mode to COOL. Note the
temperaturesettingofthethermostatandgraduallyraise
the set-point temperature until the unit de-energizes.
2.Immediately lower the set point temperature of the
thermostat to its original setting and verify that the
indoor blower is energized and outdoor unit remains
de-energized.

System Cooling
1.Set the thermostat’s system mode to COOL and the
fan mode to AUTO. Gradually lower the thermostat
temperature setpoint below room temperature and
verify the outdoor unit and indoor blower energize.
2.Verifyblowerwheelis spinning indirectionindicated by

Listen for any unusual noises.If unusual sounds occur,
determine the source of the noise and correct as
necessary.
3.Verify HI and LO refrigerant pressures.
NOTE:On3phasemodelsonly-Ifrefrigerantpressures

Verify the fan and compressor cycle off with the
thermostat.NOTE:The blower should also stop unless
fan mode is set to the ON position.
System Heating (optional)
1.Set the thermostat's system mode to HEAT and the
temperature mode above room temperature.
2.Verify the optional heating equipment (furnace or
electric heat) and indoor blower energize. Feel the air
being circulated by the indoor blower and verify that
it is warmer than ambient temperature. Listen for any

COMPONENT FUNCTIONS
High Pressure Switch (HPS) - Factory-installed and
located in the liquid line internal to the outdoor unit. The
switch is designed to protect the system when very high
pressuresoccurduringabnormalconditions.Undernormal
conditions,theswitchisclosed.Iftheliquidpressurerises
above3102 kPa (450 psig), then the switchwillopenand
de-energize the outdoor unit. The switch will close again
once the liquid pressure decreases to 2413 kPa (350
psig).Pleasenotethattheswitchinterruptsthethermostat
inputs to the unit. Thus, when the switch opens and then
closes,there will be a 5 minute shortcyclingdelaybefore
the outdoor unit will energize.
Low Pressure Switch (LPS) - Factory-installed and
locatedin thesuctionlineinternal totheoutdoorunit. The
switch is designed to protect the compressor from a loss
of charge. Under normal conditions, the switch is closed.
If the suction pressure falls below 34.4 kPa (5 psig), then
the switch will open and de-energize the outdoor unit.
The switch will close again once the suction pressure
increases above 138 kPa (20 psig). Please note that the
switch interrupts the thermostat inputs to the unit. Thus,
when the switch opens and then closes, there will be a
5 minute short cycling delay before the outdoor unit will
energize.
AIR CONDITIONER MAINTENANCE
WARNING:
To prevent electrical shock, personal injury, or
death,disconnect all electrical power to the unit
before performing any maintenance or service.
Theunitmayhavemorethanoneelectricalsupply.
Proper maintenance is important to achieve optimum
performancefromtheairconditioner.Theabilitytoproperly
perform maintenance on this equipment requires certain
mechanical skills and tools. If you do not possess these
skills, contact your dealer for maintenance. Consult your

APPLICATION NOTES FOR USING R22 REFRIGERANT
Application Notes on the Use of Charging Charts
• This equipment’s cooling system contains refrigerant under high pressure. Always use safe and
environmentally sound methods when handling refrigerant handling or servicing the unit. Review the
factory literature and safety warnings prior to servicing.

and weigh in the refrigerant to the amount specified on the unit rating label.
• Theserefrigerantchargingchartsarevalidforawidevarietyofindoorreturnairconditions(temperatureandairow)
and are most influenced by the outdoor ambient temperature, outdoor fan operation, and unit operating voltage.
Before using these charging charts, make sure the unit is in a steady operating mode.As shown in Figures 6-14
(pages 14-18) the ideal sub-cooling can vary over the range of operation. Reference these charts to determine
the ideal amount of sub-cooling for a given liquid pressure. Units charged to other values will not perform at the
rated unit capacity and/or efficiency (EER).
• Toinspectasystemsoperationusingqualityinstruments,matchthemeasuredliquidtemperaturetotheunits
