GENERAL INSTRUCTIONS

IMPORTANT

The equipment covered in this manual is to be installed by
trained, experienced service and installation technicians.
Any heat pump is more critical of proper operating charge
and an adequate duct system than a straight air
conditioning unit. All duct work, supply and return ducts,
must be properly sized for the design air flow requirement
of the equipment. ACCA is an excellent guide to proper
sizing. All duct work or portions thereof not in the
conditioned space should be properly insulated in order to
both conserve energy and prevent condensation or
moisture damage.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked
for external signs of shipping damage. If damage is found,
the receiving party must contact the last carrier
immediately, preferably in writing, requesting inspection
by the carrier’s agent.

GENERAL

The refrigerant system is completely assembled and
charged. All internal wiring is complete.

The unit is designed for use with or without duct work.
Flanges are provided for attaching the supply and return
ducts.

These instructions and any instructions packaged with any
separate equipment required to make up the entire heat
pump system should be carefully read before beginning the
installation. Note particularly “Starting Procedure” and
any tags and/or labels attached to the equipment.

While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation is
made.

FIELD INSTALLED HEATER PACKAGES
(OPTIONAL)

These packaged heat pumps are manufactured without
supplementary electric heaters. Supplementary heaters are
available for simple, fast field installation.

A separate power circuit is required for the supplementary
heaters.

IMPORTANT: Refer to Table 1 when designing duct
work for maximum available static pressure with heater
installed.

Refer to electrical data shown in Tables 3 and 4 for proper
application information on all available heater
combinations and what units they can be used with. It also
shows the applicable circuit ampacities, fuse size, and wire
size for each heater combination.

These instructions explain the recommended method to
install the air cooled self-contained unit and the electrical
wiring connections to the unit.

INSTALLATION

LOCATION

GENERAL

The unit must be located outside, or in a well ventilated
area. It must not be in the space being heated or cooled. A
sound absorbing material should be considered if the unit
is to be installed in such a position or location that might
cause transmission of sound or vibration to the living area
or adjacent buildings.

SLAB MOUNTING

In areas where winter temperatures DO NOT go below
32° F for periods over twelve hours, the unit may be slab
mounted at grade level. When installing unit at grade
level, install on a concrete slab at least four inches above
finished grade level. Slab should have a slope tolerance
away from the building structure of at lease 1/4 inch per
foot, while being level from side to side. This will prevent
ice buildup under the unit during defrost cycles. Place slab
in a location where runoff water from higher ground will
not collect around unit. See Figure 2.

A minimum of 18 inches should be provided between the
coil inlet and any building surfaces. Provide at least four
feet between coil outlet and any building wall, fences or
other vertical structures. Provide a minimum of three feet
clearance on the service access side of the unit. See
Figure 3

ROOF MOUNTING

When a unit is installed in areas where low ambient
temperatures or strong winter winds exist, it should be
placed so prevailing winter winds are not in direct line
with the heat pump coil. If this is not possible, a wind
barrier should be constructed. Place barrier 24 inches
from the coil inlet side of the unit and in the direction of
prevailing winds. Size barrier at least the same height and
width as the unit. This may be necessary on ground level
installations, also. See Figure 4.

WINTER INSTALLATION BELOW 32°F

In areas where winter conditions go below 32°F for
extended periods, the unit must be elevated above the
mounting surface to prevent snowfall or defrost ice
accumulation from interfering with the operation of the
unit. A minimum of twelve inch elevation is
recommended, while greater elevation may be required for
areas of high snow accumulation. Poured concrete, steel
framework, brick, cement block, etc., can be utilized to
construct a suitable raised mounting platform. See
Figure 5.

TYPICAL INSTALLATIONS

1.

ROOF MOUNTED

sturdy base on the roof of the building. Return air to
the unit is brought through a single return grille (grilles
with built-in filters are best since they enable easy
access for filter changing). Return air ducts are
attached to the lower section of the front panel.
Supply air is brought from the unit to attic duct work
or to a furred down hall. Supply air duct is attached to
the top of the front panel.

CAUTION: All outdoor duct work must be

thoroughly insulated and weatherproofed. All
attic duct work must be thoroughly insulated.
Two inch thick insulation with suitable vapor
barrier is recommended for both outdoor and
attic runs.

In roof top installation, as in all installations, the heat
pump must be level from side to side. However, the
unit should have a pitch along the length to assure
complete external drainage of precipitation and of
defrost condensate. See Figures 6 and 7, and Tables 6
and 7.

CRAWL SPACE

2.
space must be well insulated and provided with a
vapor barrier. In addition, the crawl space must be
thoroughly ventilated and provided with a good vapor
barrier as a ground cover. It is most desirable to install
the unit outdoors rather than inside the crawl space, so
that it will be readily accessible for service. In
addition, it is necessary to dispose of the condensate
from the outdoor coil on the heating cycle, and this is
virtually impossible with the unit installed inside the
crawl space.

SLAB MOUNTED AT GROUND LEVEL

3.
type installation is ideal for homes with a slab floor
construction where a roof mounted unit is not desired.
The supply and return duct work can be run through a
furred closet space.

THROUGH THE WALL

4.
requires a suitable framework to be fabricated capable
of withstanding the unit weight. Normally the unit will
be insulated so as to minimize supply and return duct
work.

OTHER INSTALLATIONS

5.

– Many other
installations are possible with the packaged heat pump.
No matter what the installation, always consider the
following facts:

A. Insure that the discharge air is not obstructed inany

way so as to cause operation difficulties.

B. The indoor coil drain pan is equipped with a

coupling that must be piped through a condensate
drain trap to a suitable drain.

C. Always mount the unit is such a position that it

may be easily reached for servicing and
maintenance.

D. Insure that the unit is clear so that proper air flow

over the outdoor coil will be maintained.

If this unit is operated in cooling below a 65° outdoor
ambient temperature, the installation of low ambient
controls (CMA-6) to unit is required.

CONDENSATE DRAIN TRAP

It is very important to provide a trap in the condensate
drain line to allow a positive liquid seal in the line and
assure correct drainage from the coil condensate pan.

Install condensate drain trap shown in Figure 8. Use drain
connection size or larger. Do not operate unit without
trap. Unit must be level or slightly inclined toward drain.

With a trap installed on a unit located in an unconditioned
area, water in the trap may freeze. It is recommended that
the trap material be of a type that will allow for expansion
of water when it freezes.

AIR FILTERS

Air filters for the return air side of the system are not
provided as part of the various types of applications for
these models, and must be field supplied and installed as
part of the final installation.

Prior thought should be given to return air location and
placement of the air filter(s). The air filter(s) must be of
adequate size and readily accessible to the operator of the
equipment. Filters must be adequate in size and properly
maintained for proper operation. If this is not done,
excessive energy use, poor performance, and multiple
service problems will result. It is impossible to oversize
air filters. Generous sizing will result in cleaner air and
coils as well as lower operating costs and extend the time
between required changes. Table 8 shows minimum filter
areas and recommended filter sizes. Actual filter sizes can
vary with the installation due to single or multiple returns
utilizing a filter/grille arrangement or being placed
immediately ahead of the indoor coil face in the return air
duct.

WIRING – MAIN POWER

Refer to the unit rating plate for wire sizing information
and maximum fuse size. Each outdoor unit is marked with
a “Minimum Circuit Ampacity”. This means that the field
wiring used must be sized to carry that amount of current.
If field installed heaters are added to the basic unit, a
second separate power supply circuit will be required. The
heater rating plate located adjacent to the basic unit rating
plate will show the appropriate circuit ampacity fuse size,
etc. (Also see “Electrical Data” on pages 3, 4 and 5.) All

models are suitable for connection with copper wire only.

These instructions must be adhered to. Refer to the
National Electrical Code for complete current carrying
capacity data on the various insulation grades of wiring
material.

LOW VOLTAGE WIRING

The unit rating plate lists a “Maximum Time Delay Fuse”
or “HACR” type circuit breaker that is to be used with the
equipment. The correct size must be used for proper
circuit protection and also to assure that there will be no
nuisance tripping due to the momentary high starting
current of the compressor.

WIRING – 24V LOW VOLTAGE CONTROL
CIRCUIT

Ten (10 ) wires should be run from thermostat subbase to
the 24V terminal board in the unit. A nine conductor,
18 gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in
Figure 9.

THERMOSTAT INDICATOR LAMPS

The red lamp marked “EM. HT.” comes on and stays on
whenever the system switch is placed in Em. Ht. position.
The green lamp marked “Check” will come on if there is
any problem that prevents the compressor from running
when it is supposed to be.

EMERGENCY HEAT POSITION

The operator of the equipment must manually place the
system switch in this position. This is done when there is a
known problem with the outdoor section, or when the green
“Check” lamp comes on indicating a problem.

TRANSFORMER TAPS

230/208V, 1 phase and 3 phase equipment employ dual
primary voltage transformers. All equipment leaves the
factory wired on 240V tap. For 208V operation, reconnect
from 240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:

TAP RANGE
240 253 – 216
208 220 – 187

NOTE: The voltage should be measured at the field

power connection point in the unit and while the
unit is operating at full load (maximum
amperage operating condition).

COMPRESSOR CUTOFF THERMOSTAT
and OUTDOOR THERMOSTAT WIRING

Heat pump compressor operation at outdoor temperatures
below 0° F are neither desirable not advantageous in terms
of efficiency. Since most equipment at time of
manufacture is not designated for any specific destination
of the country and most of the equipment is installed in
areas not approaching the lower outdoor temperature
range, the compressor cutoffs are not factory installed.

Outdoor thermostats are available to hold off various
banks of electric heat until needed as determined by
outdoor temperature. The set point of either type of
thermostat is variable with geographic region and sizing of
the heating equipment to the structure. Utilization of the
Heating Application Data and the heat loss calculation of
the building are useful in determining the correct set
points. Refer to Installation Instructions of CMH-14
Outdoor Thermostat Kit for more information.

ST ART UP AND OPERA TION

THREE PHASE SCROLL COMPRESSOR
START UP INFORMATION

Scroll compressors, like several other types of
compressors, will only compress in one rotational
direction. Direction of rotation is not an issue with single
phase compressors since they will always start and run in
the proper direction.

However, three phase compressors will rotate in either
direction depending upon phasing of the power. Since
there is a 50-50 chance of connecting power in such a way
as to cause rotation in the reverse direction, verification of
proper rotation must be made. Verification of proper
rotation direction is made by observing that suction
pressure drops and discharge pressure rises when the
compressor is energized. Reverse rotation also results in
an elevated sound level over that with correct rotation, as
well as, substantially reduced current draw compared to
tabulated values.

Verification of proper rotation must be made at the time
the equipment is put into service. If improper rotation is

corrected at this time there will be no negative impact on
the durability of the compressor. However, reverse
operation for over one hour may have a negative impact on
the bearing due to oil pump out.

SEQUENCE OF OPERATION

COOLING

compressor contactor starting the compressor and outdoor
motor. The G (indoor motor) circuit is automatically
completed on any call for cooling operation, or can be
energized by manual fan switch on subbase for constant air
circulation.

HEATING

controls heating cycle operation. Two thermostat options,
one allowing “AUTO” changeover from cycle to cycle and
the other constantly energizing solenoid coil during heating
season and thus eliminating pressure equalization noise
except during defrost, are to be used. On “AUTO” option,
a circuit is completed from R-W1 and R-Y on each heating
“On” cycle energizing reversing valve solenoid and pulling
in compressor contactor starting compressor and outdoor
motor. R-G also make starting indoor blower motor. Heat
pump heating cycle now in operation. The second
energizes the reversing valve solenoid constantly whenever
the system switch on subbase is placed in “Heat” position,
the “B” terminal being constantly energized from R. A
thermostat demand for heat completes R-Y circuit, pulling
in compressor contactor starting compressor and outdoor
motor. R-G also make starting indoor blower motor.

– Circuit R-Y makes at thermostat pulling in

– A 24V solenoid coil on reversing valve

NOTE: If compressor is allowed to run in reverse

rotation for several minutes the compressor’s
internal protector will trip.

All three phase ZR*3 compressors are wired identically
internally. As a result, once the correct phasing is
determined for a specific system or installation, connecting
properly phased power leads to the same Fusite terminals
should maintain proper rotation direction.

The direction of rotation of the motor may be changed by
reversing any two line connections to the unit.

Manual 2100-354
Page 19

DEFROST CYCLE

The defrost cycle is controlled by temperature and time on
the solid state heat pump control. See Figure 12.

When the outdoor temperature is in the lower 40° F
temperature range or colder, the outdoor coil temperature
is 32° F or below. This coil temperature is sensed by the
coil sensor mounted near the bottom of the outdoor coil.
Once coil temperature reaches 30° F or below, the coil
sends a signal to the control logic of the heat pump control
and the defrost timer will start.

After 30 minutes at 30° F or below, the heat pump control
will place the system in the defrost mode.

During the defrost mode, the refrigerant cycle switches
back to the cooling cycle, the outdoor motor stops, electric
heaters are energized, and hot gas passing through the
outdoor coil melts any accumulated frost. When the
temperature rises to approximately 57° F the coil sensor
will send a signal to the heat pump control which will
return the system to heating operations automatically.

If some abnormal or temporary condition such as a high
wind causes the heat pump to have a prolonged defrost
cycle, the heat pump control will restore the system to
heating operation automatically after 10 minutes.

There are three settings on the heat pump control – 30
minute, 60 minute and 90 minute. Models are shipped
wired on the 60 minute setting for greatest operating
economy. If special circumstances require a change to
another time, remove wire connected to terminal 60 and
reconnect to desired terminal. Refer to Figure 12. The
manufacturer’s recommendation is for 60 minute defrost
cycles.

FIGURE 12

HEAT PUMP CONTROL BOARD

There is a cycle speed up jumper on the control. This can
be used to reduce the time between defrost cycle operation
without waiting for time to elapse.

Use a small screwdriver or other metallic object, or another
1/4 inch QC to short between the SPEEDUP terminals to
accelerate the HPC timer and initiate defrost.

Be careful not to touch any other terminals with instrument
used to short the SPEEDUP terminals. It may take up to
10 seconds with the SPEEDUP terminals shorted for the
speedup to be completed and the defrost cycle to start.

As soon as the defrost cycle kicks in remove the
shorting instrument from the SPEEDUP terminals.

Otherwise the timing will remain accelerated and run
through the 1 minute maximum defrost length sequence in
a matter of seconds and will automatically terminate the
defrost sequence.

There is an initiate defront jumper (sen jump) on the
control that can be used at any outdoor ambient during the
heating cycle to simulate a 0° coil temperature. This can
be used to check defrost operation of the unit without
waiting for the outdoor ambient to fall into the defrost
region.

By placing a jumper across the SEN JMP terminals (a 1/4
inch QC terminal works best) the defrost sensor mounted
on the outdoor coils is shunted out and will activate the
timing circuit. This permits the defrost cycle to be checked
out in warmer weather conditions without the outdoor
temperature having to fall into the defrost region.

In order to terminate the defrost test in the SEN JMP
jumper must be removed. If left in place too long the
compressor could stop due to the high pressure control
opening because of the high pressure condition created by
operating in the cooling mode with outdoor fan off.
Pressure will rise fairly fast as there is likely no actual frost
on the outdoor coil in this artificial test condition

There is also a 5 minute compressor
time delay function built into the
HPC, This is to protect the
compressor from instances it is
helpful to the service technician to
override or speed up this timing
period, and shorting out the speedup
terminals for a few seconds can do
this.

4. Set system switch to heat or cool. Adjust thermostat
to call for heat or cool. The indoor blower,
compressor, and outdoor fan should start.

NOTE: If there is no power to 24 volt transformer, the

compressor and outdoor fan motor will not start
for 5 minutes. This is because of the
compressor short cycle protection.

CHECKING TEMPERATURE SENSOR
CHECK OUT

1. Disconnect temperature sensor from board and from
outdoor coil.

2. Use an ohmmeter and measure the resistance of the
sensor. Also use ohmmeter to check for short or open.

3. Check resistance reading to chart of resistance; use
sensor ambient temperature. (Tolerance of part is
± 10%.)

4. If sensor resistance reads very low, then sensor is
shorted and will not allow proper operation of the heat
pump control.

5. If sensor is out of tolerance, shorted, open, or reads
very low ohms then it should be replaced.

SERVICE HINTS

1. Caution homeowner to maintain clean air filters at all
times. Also, not to needlessly close off supply and
return air registers. This reduces air flow through the
system which shortens equipment service life as well
as increasing operating costs.

2. Switching to heating cycle at 75°F or higher outside
temperature may cause a nuisance trip of the manual
reset high pressure switch.

3. The heat pump wall thermostats perform multiple
functions. Be sure that all function switches are
correctly set for the desired operating mode before
trying to diagnose any reported service problems.

4. Check all power fuses or circuit breakers to be sure
that they are the correct rating.

5. Periodic cleaning of the outdoor coil to permit full and
unrestricted airflow circulation is essential.

PRESSURE SERVICE PORTS

High and low pressure service ports are installed on all
units so that the system operating pressures can be
observed. Pressure tables can be found in Tables 16
through 23 in this manual covering all models on both
cooling and heating cycles. It is imperative to match the
correct pressure table to the unit by model number.

REFRIGERANT CHARGE

The correct system R-22 charge is shown on the unit rating
plate. Optimum unit performance will occur with a
refrigerant charge resulting in a suction line temperature
(6” from compressor) as shown in Table 13.

The above suction line temperatures are based upon
80°F dry bulb/67°F wet bulb (50% RH) temperature and
rated airflow across the evaporator during cooling cycle.

FAN BLADE SETTINGS

Shown in Figure 13 are the correct fan blade setting
dimensions for proper air delivery across the outdoor coil.

Any service work requiring removal or adjustment in the
fan and/or motor area will require that the dimensions in
Table 14 be checked and blade adjusted in or out on the
motor shaft accordingly.

SUCTION AND DISCHARGE TUBE
BRAZING

Compliant Scroll compressors have copper plated steel
suction and discharge tubes. These tubes are far more
rugged and less prone to leaks than copper tubes used on
other compressors. Due to different thermal properties of
steel and copper, brazing procedures may have to be
changed from those commonly used.

•

To disconnect: heat joint Areas 2 and 3 slowly and
uniformly until braze material softens and the tube can
be pulled out of suction fitting. (See Figure 14.)

•

To connect:
– Recommended brazing materials: silfos with

minimum 5% silver or silver braze material with
flux.

BRAZING DIAGRAM

– Reinsert tube into fitting.
– Heat tube uniformly in Area 1 moving slowly to

Area 2. When joint reaches brazing temperature,
apply brazing material. (See Figure 14.)

– Heat joint uniformly around the circumference to

flow braze material completely around the joint.

– Slowly move torch into Area 3 to draw braze

material into joint. (See Figure 14.)

– Do not overheat joint.
