CAUTION

Do not screw into the side of the drain pan, or into the
indoor coil or heat strip.

Air Filter

All indoor return air must be ltered. A washable lter is

furnished with the unit, located in the return air opening.
If return duct is installed, provisions must be made to

accommodate lter servicing. If a lter is installed at a

separate central return location, then the factory furnished

lter must be removed from the unit.

Condensate Drain

Provisions must be made to properly drain the indoor and
outdoor drain pans of this appliance.

Indoor drain connection: 1/2” NPT to 3/4” PVC tting

(schedule 40). Outdoor drain connection: 3/4” NPT to 3/4”

PVC tting (schedule 40 minimum). Both drains must be

trapped as shown in Figure 5. The drain line should pitch
gradually downward at least 1” per 10’ of horizontal run to
open drain.

If local codes require the use of metal condensate lines, do

not thread metal ttings into the unit drain pan. A 1/2” x 3/4”

threaded plastic nipple is available from the manufacturer
as a kit (see the Accessories section). Thread the 1/2”

end of the nipple into the unit drain pan and make the eld

connection to the 3/4” end.

CAUTION

Use thread sealant on the threaded ttings. Install
threaded ttings by hand only. Do not over torque the

ttings.

Do not thread metal condensate ttings to unit drain

pan.

The lter should be cleaned at least three times during

each of the heating and cooling seasons, or more
frequently if unusual conditions are encountered. To clean

the washable lter, shake lter to remove excess dirt and/
or use a vacuum cleaner. Wash lter in soap or detergent
water and replace after lter is dry. It is not necessary to oil
the lter after washing.

If an installation is made in which it is more desirable to

mount the lter exterior to the unit, in the return duct work
or elsewhere, the washable lter can be used or replaced
with a disposable lter. If a disposable lter is used, use the

information provided in Table 3 when sizing the disposable

lter.

Fresh Air Intake (Fresh Air Models Only)

On fresh air capable models (designated by the FA in the
model number – e.g. 7MHP4-10-301FP), up to 5% fresh
air is drawn into the unit from outside when the indoor
blower comes on.

To access the fresh air intake feature, the threaded cap
must be removed from the fresh air intake pipe (see Figure

6). The fresh air intake pipe is located at the rear of the unit
return air intake. When not in use, cap should be placed
nearby in the air intake area in case it is needed in the
future.

WARNING

Fresh Air Intake Pipe

Threaded Cap

The location of fresh air capable models must conform to
the requirements of National Fire Protection Association
NFPA No. 54 in regards to proximity of forced air inlets

to ue gas terminals. Improper installation could result

in personal injury or death.

Thermostat

The room thermostat should be located on an inside
wall where it will not be subject to drafts, sun exposure,

or heat from electrical xtures or appliances. Follow

manufacturer’s instructions enclosed with the thermostat
for general installation procedures. Color-coded insulated
wires (#18 AWG) should be used to connect the thermostat
to the unit.

Electrical Connections

All wiring must be done in accordance with the National
Electrical Code (NEC), ANSI/NFPA No. 70 (latest edition);
Canadian Electrical Code CSA C22.2 Part 1 (latest edition);
or local codes, where they prevail. Any alteration of internal

wiring will void certication and warranty.

Units are factory wired for a 230 volt power supply. If power
supply is 208 volts, it will be necessary to change a wire
connection on unit transformer from 240 volt terminal to
208 volt terminal as shown on the wiring diagram.

Power supply to the unit must be NEC Class 1 and must
comply with all applicable codes. A fused disconnect switch

should be eld provided for the unit. The switch must be

separate from all other circuits. 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 wiring
must be sized to minimum circuit ampacity marked on the
unit. Use copper conductors only. Each unit must be
wired with a separate branch circuit and be properly fused.

NOTE: Some MHP4 models require two separate power
supply circuits. See the unit wiring diagrams and rating

plates for specications.

Operation

Sequence of Operation

Upon initial “power up” to unit, there is a 3-minute time delay
to the compressor contactor (R to Y). Any 24V interrupt (R,
C) to the defrost control will initiate the 3-minute delay to
the contactor.

Cooling

When the thermostat is in the cooling mode, the O circuit
is powered which energizes the reversing valve. Upon
cooling demand, the thermostat closes circuit R to Y and
G. Closing R to Y closes the unit contactor, starting the
compressor and outdoor fan. The thermostat automatically
closes R to G circuit which also brings on the indoor
blower at the same time. Upon satisfying cooling demand,
the thermostat will open the above circuits and open the
main contactor, stopping the compressor and outdoor
fan. The unit is equipped with a time delay; the blower will
continue to operate for 90 seconds which improves system

efciency.

Heating

Upon heating demand, the thermostat closes circuit R to
Y, which closes the unit contactor, starting the compressor
and outdoor fan. The reversing valve is not energized in
the heating mode. The thermostat again automatically
brings on the indoor fan at the same time. The second
stage of the thermostat closes circuit R to W, which closes
the unit sequencers, bringing the auxiliary electric heat on.
Upon satisfying heating demand, the thermostat opens the
above circuits and stops unit operation.

Use wiring with a temperature limitation of 75°F minimum.
Run the 208 or 230 volt, 60 hertz electric power supply
through a fused disconnect switch to the control box of the
unit and connect as shown in the wiring diagram located
on the inside of the control access panel.

The unit must be electrically grounded in accordance with
local codes or, in the absence of local codes, with the
National Electrical Code ANSI/NFPA No. 70 (latest edition)
or CSA C22.2 Part 1 (latest edition).

506325-01 Issue 1734 Page 7 of 15

NOTE: The 7.2 and 10 kW heats strips offer a W1 and
W2 thermostat connection. Taking advantage of the two
heat strip circuits requires a 3-stage thermostat (Y for heat
pump, W1 for electric heat stage 1, and W2 for electric
heat stage 2). If a 2-stage thermostat is used, “pigtail” W1
and W2 wires together when connecting the thermostat
wires at the unit.

TEST

NORM

DLY

NOPS

If the outdoor ambient conditions are such that frost forms
on the outdoor coil, the defrost control monitors the need
for, initiates, and terminates defrost cycles as necessary to
maintain system performance. The defrost control is time/
temperature initiated and temperature terminated with
a maximum defrost time (time-out) of 10 minutes. Time
between defrost cycles is preset at 60-minute intervals at

the factory, but can be eld adjusted between 30, 60, or 90
minutes. To eld adjust time between defrost cycles, place

defrost time plug in the proper position (see Figure 8).

Figure 7. Defrost Control

The defrost control is also equipped with a set of pins to aid
in the troubleshooting of the defrost system (see Figure 8).
The following is a brief outline of the testing of the defrost
system.

1. Defrost sensor must be closed, 32°F or below. If
temperatures are such that the switch will not close,
jumper between defrost sensor terminals on the
defrost control.

2. Start system in heating operation.

3. Jumper test pins. A 1/4” quick connect terminal
crimped onto a solid wire or brazing rod works well for
a test jumper. Closing test pins speeds up time interval
by a factor of 256.

Defrost Control Setting Defrost Test Cycle Time

30 minutes 7 seconds

60 minutes 14 seconds

90 minutes 21 seconds

Table 4. Defrost Test Cycle Time

After closing test pins and appropriate cycle time has
elapsed, the reversing valve should shift to defrost mode
and the outdoor fan should stop. After 2 seconds of defrost
operation, the reversing valve should shift back to heating
operation and the outdoor fan should start.

Figure 8. Defrost Jumpers

Defrost control will initiate a defrost cycle if the time period
has elapsed and the defrost sensor sees a temperature
below freezing. At the start of a defrost cycle, the defrost
control will energize the reversing valve solenoid, shifting
the reversing valve and de-energizing the outdoor fan. The
defrost relay will also close, energizing auxiliary heat for
increased comfort during defrost. The unit will remain in
defrost until the defrost sensor has determined that the
frost has been removed from the coil or a 10-minute time
period has elapsed.

Quiet Defrost Feature

The defrost control in this appliance is equipped with a
quiet defrost feature. With the jumper pin set at the DLY
position, at the start of the defrost cycle, the defrost control
will energize the reversing valve solenoid and de-energized
the outdoor fan, and de-energize the compressor circuit a
period of 10 seconds. The result is a much quieter defrost
cycle.

All units have the jumper pin set at the NORM position.
PS1 and PS2 terminals: These appliances are not
equipped with a pressure switch in the refrigeration system.
Therefore, the jumper on the NOPS pin is factory installed
and required.

System Performance

For maximum performance of this electric cooling system,
the operating temperatures and pressures should be
checked and superheat determined at Standard ARI test
conditions of 82°F outdoor – 80°F indoor dry bulb/67°F
wet bulb. If superheat measured deviates from the values
given in Table 5, refrigerant charge should be adjusted
accordingly for maximum performance.

clean the washable lter as necessary (a minimum of three

times each heating or cooling season is recommended).

Do not replace washable lter with a disposable lter
unless an installation was made in which the lter was

mounted exterior to the unit.

Motors

The indoor and outdoor fan motors are permanently
lubricated and require no maintenance.

Outdoor Coil

Foreign material 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. To clean the coil, remove the lower access panel
and blow out debris by using compressed air or water. Be

sure power to unit is shut off before using water to
clean the coil.

Care should be used when cleaning the coils so that

the coil ns are not damaged.
