The best protection for the wiring is the lowest rated
fuse or circuit breaker which will supply power to the
unit during normal operation without nuisance trips.
Such a device will provide maximum circuit protection.
DO NOT EXCEED THE MAXIMUM OVERCURRENT
DEVICE SIZE SHOWN ON UNIT DATA PLATE.
All line voltage connections must be made through
weatherproof fittings. All exterior power supply and
ground wiring must be in approved weatherproof con-
duit. Low voltage wiring from the unit control panel to
the thermostat requires coded cable.
Flexible Set-Up For Wiring On The Left Or Right
Side
Even though the electrical box is on the left side of the
unit, both line voltage and low voltage wiring can enter
the unit according to the following (see dimension draw-
ing on the Specification Sheet for knockout locations):
• Line voltage, electrical heater wiring, and low volt-
age on the right side.
• Line voltage and low voltage wiring on the left side
with electrical heater wiring on the right side.
• Line voltage and electrical heater wiring on the right
side with low voltage wiring on the left side.
• Low voltage wiring on the left side and line voltage
and electric heater wiring on the right side.
Using the single-point wiring kit adds further flexibility to
installation wiring.
Unit Voltage
The unit transformer is factory connected for 230V
operation. If the unit is to operate on 208V, reconnect
the transformer primary lead as shown on the unit
wiring diagram.

Ductwork
Duct systems and register sizes must be properly de-
signed for the C.F.M. and external static pressure rating
of the unit. Ductwork should be designed in accordance
with the recommended methods of Air Conditioning
ContractorsofAmericaManual D(Residential)orManual
Q (Commercial). All ductwork exposed to the outdoors
must include a weatherproof barrier and adequate insu-
lation.
A duct system should be installed in accordance with
Standards of the National Board of Fire Underwriters for
the Installation of Air Conditioning, Warm Air Heating
and Ventilating Systems. Pamphlets No. 90A and 90B.
The warm air supply duct from the unit through a wall
fabricated of combustible material may be installed
without clearance. However, minimum clearances for
the unit must be observed as shown in Specification
Sheet.
The outlet duct should be provided with an access
panel.
For vertical airflow, the ductwork should be attached to
the roof curb prior to installing the unit. Ductwork di-
mensions are shown in the Amana PRC roof curb instal-
lation manual.
If desired, supply and return duct connections to the unit
may be made with flexible connections to reduce
possible unit operating sound transmission.
Filters
CAUTION
To prevent property damage due to fire
and loss of equipment efficiency or
equipment damage due to dust and lint
build up on internal part, never operate
unit without a filter installed .
Even though a return air filter is not supplied with this
unit, there must be a means of filtering all return air.
Refer to Specification Sheet provided with unit for filter
size information.
If using the Over/Under Transition Kit, the filter(s) may
be located in the return air duct(s) or return air filter
grille(s). Filters installed external to the unit should be
sized in accordance with their manufacturer recommen-
dations. A throwaway filter must be sized for a maxi-
mum face velocity of 300 feet per minute.
Filter Installation
Important: When installing a filter, the air flow arrows
on the filter must point toward the indoor blower.

Operating Instructions
1. Turn on the electrical power supply to the unit.
2. Place the room thermostat selector switch in the
COOL or HEAT position (or AUTO if available, and
if automatic changeover from cooling to heating is
desired).
3. Set the room thermostat to the desired tempera-
ture.
X. Maintenance
WARNING
To avoid death or personal injury due to
electrical shock, disconnect electrical
power before performing any mainte-
nance.
Replacing Or Cleaning Filter
A return air filter is not supplied with this unit; however,
there must be a means of filtering all of the return air.
The filter(s) may be located in the return air duct(s),
return air filter grille(s). Consult with your installing
dealer for the actual location of the return air filter(s) for
your unit.
Dirty filters are the most common cause of inadequate
heating or cooling performance. Filter inspection should
be made at least every two months; more often if
necessary because of local conditions and usage.
Dirty throwaway filters should be discarded and re-
placed with a new, clean filter. Dirty permanent filters
should be washed with water, thoroughly dried and
sprayed with a filter adhesive before being reinstalled.
(Filteradhesivesmaybe foundatmanyhardware stores.)
Permanent filters should last several years. However,
should one become torn or uncleanable, it should be
replaced.
Maintaining Cabinet Finish
Use a fine grade automotive wax on the cabinet finish
to maintain the finish’s original high luster. This is espe-
cially important in areas with high ultraviolet radiation.
Clean Outside Coil (Qualified Servicer
Only)
The coil with the outside air flowing over it should be
inspected annually and cleaned as frequently as neces-
sary to keep the finned areas free of lint, hair and
debris.
VII. Condensate Drain
Condensate Drain Connection
This unit has a built-in trap - no external trap is required;
the drain may be extended using 3/4” PVC piping.
VIII. Sequence of Operations
Normal Sequence of Operations
NOTE: There is a fan delay on initial power to unit
before the low voltage board resets and is operational.
1. Thermostat calls for heating or cooling. The com-
pressor and outdoor fan are energized.
2. Approximately 30 seconds later, the indoor fan
starts.
3. The unit will deliver heating or cooling to the condi-
tioned space until the thermostat is satisfied.
4. The compressor and outdoor fan will be de-ener-
gized when the thermostat opens.
5. The indoor fan continues to run for approximately
30 seconds after the thermostat is satisfied. This
allows additional cooling from the indoor coil to be
transferred to the conditioned space. Then, the in-
door fan stops.
IX. Startup and Adjustment
CAUTION
This unit must not be used as a “con-
struction heater” during the finishing
phases of construction on a new struc-
ture. This type of use may result in pre-
maturefailureoftheunitduetoextremely
low return air temperatures and expo-
sure to very dirty atmospheres.
Compressor Protection Devices
The PHB**C and PHD**C compressor includes compo-
nents which are designed to protect the compressor
against abnormal operating conditions.
WARNING
To avoid death or personal injury, al-
ways disconnect electrical power before
inspecting or servicing the unit. All com-
pressor protection devices reset auto-
matically, energizing the contactor and
outdoor fan.
