COMPRESSORS
The compressor used in this product is specifically designed to operate
with R-410A Refrigerant and cannot be interchanged.
!
CAUTION
Procedures which risk oil leakage include, but are not limited to, compressor replacement, repairing refrigerant leaks, replacing refrigerant
components such as filter drier, pressure switch, metering device or
coil.
Units are shipped with compressor mountings which are factoryadjusted and ready for operation.
This system uses R-410A Refrigerant which operates at higher pressures than R-22. No other refrigerant may be used in this system.
The compressor uses polyolester (POE oil), Mobile 3MA POE. This oil
is extremely hygroscopic, meaning it absorbs water readily. POE oil can
absorb 15 times as much water as other oils designed for HCFC and
CFC refrigerants. If refrigerant circuit is opened, take all necessary precautions to avoid exposure of the oil to the atmosphere.
!
CAUTION
Do not leave the system open to the atmosphere. Unit damage could
occur due to moisture being absorbed by the POE oil in the system.
This type of oil is highly susceptible to moisture absorption
POE (polyolester) compressor lubricants are known to cause long term
damage to some synthetic roofing materials.
!
CAUTION
!
CAUTION
Do not loosen compressor mounting bolts.
PHASING
Three-phase, scroll compressors operate in only one direction. If the
scroll is drawing low amperage, has similar suction and discharge pressures, or is producing a high noise level, the scroll is out of phase.
Change the incoming line connection phasing to obtain the proper rotation.
!
CAUTION
Scroll compressors require proper rotation to operate
properly. Failure to check and correct rotation may result
in property damage.
Exposure, even if immediately cleaned up, may cause embrittlement
(leading to cracking) to occur in one year or more. When performing
any service that may risk exposure of compressor oil to the roof, take
precautions to protect roofing.

NOTE: Filter pressure drop based on standard filter media tested at velocities
not to exceed 300 ft/min.
1. The pressure drop through the economizer is greater for 100% outdoor air
than for 100% return air. If the resistance of the return air duct is less than
0.25 IWG, the unit will deliver less CFM during full economizer operation.
SECTION VI: OPERATION
The following sequences of operation are based on using a singlestage heat pump thermostat.
COOLING SEQUENCE OF OPERATION
1. When the fan switch on the thermostat is in the “ON” position, the 24
volts at “G” will bring on the indoor blower motor at the selected airflow. When the fan switch on the thermostat is in the “AUTO” position, the blower operates only when there is a call for cooling or
heating by the thermostat.
2. On a call for cooling, the thermostat sends 24 volts to “Y” and “O” to
the defrost control board. The reversing valve solenoid is energized, and after the antishort cycle period is complete contactor coil
M is energized. Power is supplied to the compressor and outdoor
fan motor, and the reversing valve switched to the cooling position.
When the fan switch on the thermostat is in the “AUTO” position the
indoor blower motor is energized at the YSPD airflow.
3. When the demand for cooling has been satisfied, the 24 volt “Y”
signal is removed, and the M contactor is de-energized. When the
fan switch on the thermostat is in the “ON” position, the indoor
blower motor continues to run at GSPD. If the fan switch is in the
“AUTO” position. the indoor motor ramps down after a 60 second
delay.
Johnson Controls Unitary Products
1. When the fan switch on the thermostat is in the “ON” position, the 24
volts at “G” brings on the indoor blower motor at the GSPD. When
the fan switch on the thermostat is in the “AUTO” position, the blower
operates when there is a call for heating by the thermostat.
2. On a call for heating, the thermostat sends 24 volts to “Y” on the
defrost control board. After the anti-short cycle period is complete,
the 24 volt signal energizes contactor coil M and power is supplied
to the compressor and outdoor fan motor. The reversing valve
remains in the heating position. When the fan switch on the thermostat is in the “AUTO” position, the indoor blower is energized at the
YSPD.
3. For units equipped with supplementary electric heat, when the heat
pump cannot meet the demand, the thermostat “W” sends 24 volts.
This signal is sent through the defrost control terminals “W” to
“Wout” an energizes the WSPD. The 24 volt signal energizes 1st
stage of optional electric heat (if installed).
4. When the heating demand is satisfied, the electric heat is de-energized when the 24 volt “W” signal is removed, and the M contactor
is de-energized when the 24 volt “Y” signal is removed. When the
fan switch on the thermostat is in the “ON” position, the indoor
blower continues to run. When the fan switch is in the “AUTO” position, the indoor blower motor ramps down after a 60-second delay.
Please refer to Table 13 for more information.
DEFROST OPERATION
The demand defrost control implements a temperature differential
(”delta-T”) demand defrost algorithm. The heat pump is allowed to operate in the heating mode until the combination of outdoor ambient and
outdoor coil temperatures indicate that defrosting is necessary. When
coil temperature is below the initiate point for the ambient temperature
continuously for 4-1/2 minutes, the heat pump is put into a defrost cycle.
This 4-1/2 minute timer eliminates unnecessary defrost cycles caused
by refrigeration surges such as those that occur at the start of a heating
cycle.
A timed inhibit feature prevents the system from responding to a call for
defrost less than 40 minutes after the initiation of the previous defrost.
After the 40 minute inhibit time has expired, temperature conditions
must call for defrost continuously for 4-1/2 minutes before a defrost
cycle is initiated. A temperature inhibit feature prohibits defrost if the coil
temperature is above 40°F.
A forced-defrost feature puts the system into a defrost period every 6
hours and 4 minutes of accumulated compressor run-time to recirculate
lubricants, unless the coil temperature is above 40°F and the ambient
temperature is above 50°F. All defrost timing occurs only while the compressor is on. Defrost curve selection maybe switched to pin 4 if a more
aggressive defrost cycle is necessary.
During the defrost mode, the reversing valve is energized, the outdoor
fan is de-energized, the compressor is energized, and the defrost control will provide a 24 volt signal from terminal “W out” to energize electric heat stage 1, if the unit is so equipped.
For trouble shooting purposes, the defrost cycle can be manually initiated by shorting the “TEST” pins together for 5 seconds while “Y” is
energized. After removing the short, defrost will terminate normally
during the “TEST” mode.

Heat Pump Safety Switch Operation
Electric Heat Limit Switch Operation
The unit is equipped with a safety package. The refrigeration system
will be protected against high refrigerant pressure and a loss of charge
switch. If either of these safety switches open, the unit will be shut off
for the 5 minute anti-short cycle time. Once this has expired, a six hour
elapsed run timer begins. If a second opening of a safety switch occurs
during this six hour period, the compressor will be locked out.
6HK three phase heat kits utilize a normally closed low voltage limit
switch, normally closed line voltage limit switch, and a normally closed
fusible link. If the fusible link opens, it must be replaced with the appropriate OEM part and the cause must be investigated and corrected.
Resetting the lockout function is accomplished by:
1. Removing power from the control's thermostat 1st stage (Y) input for
longer than 2 seconds.
2. Removing power from “R” for more than 2 seconds.
3. Shorting the “TEST” pins together for more than 2 seconds while
“Y” is energized.
4. Shorting the “TEST” pins together for more than 5 seconds while
“Y” is de-energized.

When the limit switch opens, the heating elements will turn off. The
indoor blower will continue to run. The limit switch will automatically
reset when the temperature has fallen to a normal level, at which time
the heating elements will be turned on again.

STARTUP
Compressor Rotation
1. Check the electrical supply voltage being supplied. Be sure that it is
within the specified range on the unit data plate.
2. Make sure all electrical connections are tight.
3. Turn unit electrical power on.
4. Set the room thermostat to COOL mode and lower the desired temperature setting lower than the room temperature to create a call for
cooling.
5. Measure the total system duct static and set the blower motor cooling speed appropriately per airflow performance tables.
6. If an optional electric heat kit was installed make sure the minimum
blower speed required per Table 10 is set.
7. Make sure all units panels are in place and secured, and that an air
filter is installed.
Three-phase, scroll compressors operate in only one direction. If the
scroll is drawing low amperage, has similar suction and discharge pressures, or is producing a high noise level, the scroll is out of phase.
Change the incoming line connection phasing to obtain the proper rotation.
EXTERNAL STATIC PRESSURE SETUP
To measure external static pressure:
•

OUTDOOR COIL - Dirt should not be allowed to accumulate on the outdoor coil surface or other parts in the air circuit. Cleaning should be as
often as necessary to keep the coil clean. If water is used to clean the
coil, be sure that the power to the unit is shut off prior to cleaning.
NOTICE
!
CAUTION
Exercise care when cleaning the coil so that the coil fins are not damaged.
Do not permit the hot outdoor air discharge to be obstructed by overhanging structures or shrubs.
TROUBLESHOOTING
!
WARNING
Troubleshooting of components necessarily requires opening the
electrical control box with the power connected to the unit. Use
extreme care when working with live circuit! Check the unit nameplate for the correct range before making any connections with line
terminals.
!
CAUTION
The wire number or color and terminal designations referred to may
vary. Check the wiring label inside the control box access panel for
the correct wiring.
DO NOT use a pressure washer as coil fin damage will occur.

R-410A QUICK REFERENCE GUIDE
Refer to Installation Instructions for specific installation requirements
R-410A refrigerant operates at 50 - 70 percent higher pressures than R-22. Be sure that servicing
equipment and replacement components are designed to operate with R-410A.
R-410A refrigerant cylinders are rose colored.
Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400, or DOT BW400.
Recovery equipment must be rated for R-410A.
DO NOT use R-410A service equipment on R-22 systems. All hoses, gages, recovery cylinders, charging
cylinders and recovery equipment must be dedicated for use on R-410A systems only.
Manifold sets must be at least 700 psig high side, and 180 psig low side, with 550 psig retard.
All hoses must have a service pressure rating of 800 psig.
Leak detectors must be designed to detect HFC refrigerants.
Systems must be charged with liquid refrigerant. Use a commercial type metering device
in the manifold hose.
R-410A can only be used with POE type oils.
POE type oils rapidly absorb moisture from the atmosphere.
Vacuum pumps will not remove moisture from R-410A refrigerant oils.
Do not use liquid line driers with a rated working pressure rating less than 600 psig.
Do not install suction line driers in the liquid line.
A liquid line drier is required on every unit.
Do not use a R-22 TXV. If a TXV is to be used, it must be a R-410A TXV.
Never open system to atmosphere when under a vacuum.
If system must be opened for service, evacuate system then break the vacuum with dry nitrogen
and replace all filter driers.
