DUCTWORK

NOTICE

All units are shipped in the horizontal supply/return configuration. It is
important to reduce the possibility of any air leakage through the bot­tom duct covers (resulting from cut, torn, or rolled gasket) due to
improper handling or shipping processes. To ensure a good tight
seal, it is recommended that silicone caulk and/or foil tape be applied
along the cover edges.

These units are adaptable to downflow use as well as rear supply and
return air duct openings. To convert to downflow, use the following
steps:

1. Remove the duct covers found in the bottom return and supply air
duct openings. There are four (4) screws securing each duct cover
(save these screws to use in Step 2).

2. Install the duct covers (removed in step one) to the rear supply and
return air duct openings. Secure with the screws used in step one.

3. Seal duct covers with silicone caulk.

Duct work should be designed and sized according to the methods of
the Air Conditioning Contractors of America (ACCA), as set forth in their
Manual D.

A closed return duct system shall be used. This shall not preclude use
of economizers or ventilation air intake. Flexible duct connectors are
recommended in the supply and return duct work to minimize the trans­mission of vibration and noise.

!

CAUTION

When fastening duct work to the side duct flanges on the unit, insert
the screws through the duct flanges only. DO NOT insert the screws
through the casing. Outdoor duct work must be insulated and water­proofed.

NOTICE

Be sure to note supply and return openings.

Refer to Figures 4 and 5 for information concerning rear and bottom
supply and return air duct openings.

FILTERS

Proper filter size is very important. Filter size, type and pressure drop
should always be considered during duct system design.

All 3 phase units include a filter frame kit which is shipped inside the
unit from production. Field installation is required.

A filter rack and high velocity filters are standard on three phase units.
Filters must always be used and must be kept clean. When filters

become dirt laden, insufficient air will be delivered by the blower,
decreasing your units efficiency and increasing operating costs and
wear-and-tear on the unit and controls.

Filters should be checked monthly; this is especially important since this
unit is used for both heating and cooling.

CAUTION

This system uses R-410A refrigerant which operates at higher pres­sures than R-22. No other refrigerant may be used in this system.
Gauge sets, hoses, refrigerant containers and recovery systems
must be designed to handle R-410A. If you are unsure, consult the
equipment manufacturer. Failure to use R-410A compatible servicing
equipment may result in property damage or injury.

!

WARNING

Wear safety glasses and gloves when handling refrigerants. Failure
to follow this warning can cause serious personal injury.

Refer to Figure 13 for the R-410A Quick Reference Guide.

THERMOSTAT

The room thermostat should be located on an inside wall approximately
60" above the floor where it will not be subject to drafts, sun exposure
or heat from electrical fixtures or appliances. Sealant should be used
behind thermostat to prevent air infiltration. Follow manufacturer's
instructions enclosed with the thermostat for general installation proce­dure. Color coded insulated wires (minimum #18 AWG) should be used
to connect thermostat to unit. See Figure 6.

If a field supplied electric heat kit is installed, this unit requires the use
of a 3 heat / 2 cool (3H/2C) heat pump thermostat for proper operation.
For units installed with 6HK heat kits of 18 kW and larger, a 4H/2C heat
pump thermostat should be used. Do not use power stealing thermo­stats.

POWER AND CONTROL WIRING

Field wiring to the unit must conform to provisions of the current N.E.C.
ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be
electrically grounded in accordance with local codes or, in their
absence, with the N.E.C./C.E.C. Voltage tolerances which must be

maintained at the compressor terminals during starting and running
conditions are indicated on the unit Rating Plate and Table 1.

The wiring entering the cabinet must be provided with mechanical
strain relief.

A fused disconnect switch should be field provided for the unit. If any of
the wire supplied with the unit must be replaced, replacement wire must
be of the type shown on the wiring diagram.

Electrical service must be sized properly to carry the load. Each unit
must be wired with a separate branch circuit fed directly from the main
distribution panel and properly fused.

Refer to Figures 6 and 7 for typical field wiring and to the appropriate
unit wiring diagram for control circuit and power wiring information.

Unit comes wired for 230 volt power. If supply power is 208 volt, wires
connected to the control transformer 230V tap must be moved to the
208V tap.

Minimum wire size of 18 AWG wire should be used for all eld
installed control wiring.

COMPRESSORS

!

CAUTION

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 used in this product is specifically designed to operate
with R-410A refrigerant and cannot be interchanged. Compressors
used in PHE6 models contain two internal bypass ports which enable
the compressor to operate at 67% part load capacity.

!

CAUTION

Scroll compressors require proper rotation to operate properly. Fail­ure to check and correct rotation may result in property damage.

NOTICE

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 misphased.

Check compressor rotation. If the scroll is misphased, change the
incoming line connection phasing to obtain the proper rotation.

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

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.

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.

!

CAUTION

Do not loosen compressor mounting bolts.

Units are shipped with compressor mountings which are factory­adjusted and ready for operation.

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.

2. Filter pressure drop based on standard filter media tested at velocities not
to exceed 300 ft/min.

SECTION VI: OPERATION

The unit is controlled by a heat pump heating/cooling thermostat.
If an electronic thermostat is used, make sure it has a common connec-

tion. DO NOT use a power stealing thermostat.
This unit has a multi-stage compressor, therefore the unit has two

stages of mechanical heat, and two stages of mechanical cooling. The
unit may be controlled using a single stage heat / single stage cool (1H/
1C) heat pump thermostat, but the second stage cooling or heating is
not available unless the unit control is physically wired for full capacity
operation. For optimum performance, it is recommend to use a four
stage heat / two stage cool (4H/2C) heat pump thermostat. If a 15 kW or
smaller heat kit is installed, use a three stage heat / two stage cool (3H/
2C) heat pump thermostat.

COOLING SEQUENCE OF OPERATION

A call for a compressor cooling signal from the thermostat is initiated at
the “Y1” terminal (for OD compressor) and the “O” terminal (for revers­ing valve).

The control cycles the compressor and indoor blower to second stage
cooling speed anytime a second stage cooling “Y2” call is received
during a first stage cooling “Y1” call. The control does not operate on
second stage cooling without a call on the “Y2” thermostat input.

1. On a call for cooling, the thermostat sends 24 volts to “Y” and “O” on
the defrost control board. The reversing valve solenoid is energized.
After the antishort cycle period is complete, the contactor coil “M” is
energized. Power is supplied to the compressor and outdoor fan
motor, and the reversing valve is switched to the cooling position.
The indoor blower is controlled by the indoor blower control board. It
operates on the “LOW COOL” or “HIGH COOL” speed based on the
24 VAC input from the defrost control board. If the control receives an
“O” input without a “Y” input, it energizes the reversing valve only.

2. When the demand for cooling has been satisfied, the 24 volt “Y”
signal is removed, and the contactor is de-energized. The indoor
blower motor continues to run and ramps down after a 60 second
delay.

Dehumidification/Humidity Switch Input

This model unit features a built in de-humidification feature for
advanced dehumidification during cooling operation. The unit indoor
blower control is designed to work with a humidity control that closes
when the humidity is below the set-point. The control is open when the
humidity is above the set-point. This humidity control may be referred to
as a humidistat or dehumidistat.

To use this feature, the control HUM STAT jumper must be set to YES
and a humidistat is connected from the low voltage R and HUM color
coded leads. During cooling operation if the humidity level is above the
humidistat set point, the indoor blower speed is reduced by approxi­mately 15%.

Safety Controls

!

WARNING

The ability to properly perform maintenance on this equipment
requires certain expertise, mechanical skills, tools and equipment. If
you do not possess these, do not attempt to perform any mainte­nance other than those procedures recommended in this Installation
Manual. Failure to heed this warning could result in serious injury
and possible damage to this equipment.

The control circuit includes the following safety controls:
High Pressure Switch (HPS) - The switch protects against excessive

discharge pressures and the defrost control locks out compressor oper­ation.

Loss of Charge Switch (LCS) - The switch protects against loss of
charge due to a leak in the system.

The above pressure switch is specifically designed to operate with R­410A systems. R-22 pressure switches must not be used as replace­ments for the R-410A pressure switches.

Indoor Circulating Blower

When the thermostat calls for “FAN,” the thermostat terminal “G” is
energized signaling the indoor blower control board to operate the cir­culating blower to run continuously.

If a call for “COOL” occurs on “Y1,” the indoor blower runs at the “LOW
COOL” speed based on the “COOL” jumper setting. If a call for cool is
present on “Y1”+”Y2,” the indoor blower runs at the “HIGH COOL”
speed based on the “COOL” jumper setting.

If a call for “HEAT” occurs “W1” or “W1”+“W2”, the circulating blower
runs at the heat speed based on the “HEAT” jumper setting.

When the thermostat ends the call for “FAN,” the thermostat terminal
“G” is de-energized, and the indoor blower control board stops the cir­culating blower operation.

Delay Profiles

The Delay Profiles for each Delay jumper setting are shown in Table 16.
The levels shown in the Pre-Run, Short-Run, and Run Periods are a
percentage of the fan speed corresponding to the thermostat call. The
Post-Run and Off Delay levels are derived from the level of the previous
state, not the fan speed corresponding to the thermostat call. If in Delay
Profile B and in the Short-Run Period (82% of capacity) and the thermo-

stat call is removed, this causes control to enter the Post-Run state.
The Post-Run state level for Delay Profile B is 100% of the previous
level, so the level during the Post-Run state is 82%.

HEATING SEQUENCE OF OPERATION

1. On a call for heating, the thermostat sends 24 volts to “Y1” or
“Y1”+“Y2” on the defrost control board. After the anti-short cycle
period is complete, the 24 volt signal from “Y1” energizes contactor
coil “M” to supply power for the compressor and outdoor fan motor.
The indoor blower control operates the indoor blower motor at the
“LOW COOL” speed. If the 24 volt signal from “Y2” is present, the
defrost control board energizes the 2nd stage compressor solenoid
and signals the indoor blower control to operate the indoor blower
motor at the “HIGH COOL” speed. The reversing valve remains in
the heating position. Indoor blower speeds are selected by the
“COOL” jumper on the indoor blower control board.

2. If the heat pump cannot meet the heating demand using mechanical
(compressor) heating, the indoor thermostat may energize axillary
(electric) heating to supplement the mechanical heating if an electric
heat kit was field installed. The room thermostat sends a 24 VAC sig­nal on “W1” or “W1”+“W2.” The “W1” signal is received by the indoor
blower control board which then energizes the “HT1” output for elec­tric heat. When a call for mechanical heating and supplemental heat­ing is present, the indoor blower control operates the indoor blower at
either the “Y1”+”Y2” or the “W1” speed whichever is higher based on
the “COOL” and “HEAT” jumper selection.

NOTICE

The “W1” must be energized with “W2” in order to enable indoor air
flow.

nd

A 2

stage auxiliary electric heating “W2” from the thermostat is to

be wired directly to the second stage heat kit input.

3. 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 switches 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 the
blower off delay.

4. Refer to Table 13 for more information on electrical heat blower
OFF delay.

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.

During the defrost mode, the reversing valve is energized, the outdoor
fan is de-energized, the compressor is energized, and the defrost con­trol provides a 24 volt signal from terminal “W1OUT” to energize electric
heat stage 1 if the unit is equipped with electric heat.

By selecting “LO” on the “DEFROST HEAT” jumper, “W1 OUT” is ener­gized during defrost. By selecting “HI” on the “DEFROST HEAT”
jumper, “W1 OUT” and “W2 OUT” are energized during defrost.

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

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.

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.

Demand Defrost Fault Code Display

The control provides fault codes using the Status LED display. Table 19
describes the LED displays for fault codes. On the LED display, the
control displays a single fault code only. The control displays the fault
code on the LED display repeatedly with a 2 second off period between
repetitions of the fault code. If multiple fault codes are present at the
same time, the LED displays only the highest priority fault. The other
active faults may be accessed via the LAST ERROR button on the con­trol board.

STARTUP

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. If unit is connected to 208 volt supply power, the control transformer
must be wired accordingly.

4. Turn unit electrical power on.

5. Set the room thermostat to COOL mode and lower the desired tem­perature setting lower than the room temperature to create a call for
cooling.

!

CAUTION

Scroll compressors require proper rotation to operate properly. Fail­ure to check and correct rotation may result in property damage.

NOTICE

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 misphased.

6. Check compressor rotation. If the scroll is misphased, change the
incoming line connection phasing to obtain the proper rotation.

7. Measure the total system duct static, and set the blower motor cool­ing speed appropriately per airflow performance tables.

8. Make sure all unit panels are in place and secure and that an air fil­ter is installed.

EXTERNAL STATIC PRESSURE SETUP

To measure external static pressure:

• Measure the supply air static pressure

• Record this positive number

• Measure the return air static pressure

• Record this negative number

• Treat the negative number as a positive and add the two numbers
together

• This is total system static

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 lter driers.
