•Automatic 3-minute compressor lockout -After the com-
pressor cycles off, it will not restart for three minutes.
•Automatic 2nd stage electric heat - If the room tempera-
ture falls to 4°F below the set point temperature, the
reverse cycle heat is shut off and the electric strip heat is
turned on.
•Automatic freeze protection - Whenever power is sup-
plied to the unit and the master switch is in the ON posi-
tion, automatic freeze protection is active. If the unit
senses temperature below 40°F, the fan motor and elec-
tric strip heat are turned on. Freeze protection can be
turned off, if required.
•Random restart delay - To help eliminate power surges
after a power outage, the unit is equipped with a two to
four minute random restart delay feature. Whenever the
unit is plugged in with the master switch turned on and
the mode switch set in the cool or heat mode, a random
restart will occur. A random restart condition can be
avoided by setting the mode switch in the fan only or off
position before applying power to the unit.
•Fuse holder - On all 265 volt units, fuse holders are fac-
tory installed. Check for blown fuse if unit does not oper-
ate. Fuse holder is located behind the front. Replacement
fuses may be purchased from the Parts Department or
contact your sales representative for part numbers.

•Indication LEDs - The touch pad has LEDs that correspond
to fan operation and to indicate unit status. The LEDs
next to the selections OFF, COOL, and HEAT indicate which
operational mode is active. The LED located in the lower
left corner is a status LED. This LED indicates the status of
the unit. See Diagnostic Maintenance & Status Report sec-
tion for further details.

•Load shedding - When input terminals have been config-
ured for load shedding operations. If at any time a switch
is closed between the IN1 and COM or IN2 and COM termi-
nals as configured, the compressor and electric heater
will lockout until the switch is opened.
NOTE: ThePTACWireHarnessKit(PWHK01G70)isrequiredwhen
using or load shedding option.
•Transfer fan - A daughter board allows for an external
(transfer) fan connection. Auser-supplied relay is required
and, depending upon the type used, an approved external
transformer kit may be required for installation.
•Front mounting hole - A mounting hole location is pro-
vided to give the owner the option of securing the front to
the chassis. The mounting hole must be drilled at the
dimple indicating the correct location below a louver. The
owner must supply one 1/2 inch long #8 sheet metal screw
per unit. The screw must be removed before the front can
be removed.

•Energy Management System Features
Temperature Setback - This option can save energy dol-
lars for unrented or unoccupied rooms by automatically
setting back the operational temperatures. This mode of
operation is selected through the configuration routine
(see Configuration Settings section). NOTE: Temperature
setback does not work with a wired remote thermostat.
Door Switch and Motion Sensor Low VoltageTerminals (IN1,
IN2, COM) - The door switch and motion sensor operate as
a unit, the terminals allow for wired connection of a door
sensor to the control board. The motion sensor interprets
any door movement as a signal of occupancy. If the switch
between IN* and COM is closed, the door control will in-
terpret the room door as closed. If the switch between
IN* and COM terminals is opened (or closed if unit is con-
figured for normally open) the control will interpret the
action as a signal of occupancy. If thirty minutes pass with-
out any door activity, Energy Management Temperature
setback activates.
Serial Port Interfaces - A serial port, located on the con-
trol board, provides easy access for two-way communica-
tions to the control board from an optional RF antennae
can be attached for wireless communications.

THERMOSTAT LOCATION
This unit is designed to be operated with remote wall mounted
thermostats. For further information on thermostats approved
for use with this unit, contact your sales representative.
For best performance results, the thermostat should be located
approximately five feet above the floor on a vibration free,
inside wall in an area with good air circulation.
Do not install the thermostat where it may be affected by the
following:
• Dead spots behind doors, in corners or under cabinets
• Hot or cold drafts from air ducts
• Radiant heat from the sun, appliances, or fireplaces
• Concealed pipes and chimneys
• Unheated (uncooled) areas behind the thermostat, such
as an outside walls
Consult the instruction sheet packaged with the thermostat for
further details on mounting and operation.

descriptionpertainstoapprovednonprogrammablethermostats
that energize G in Heat and Cool mode.
HEAT/OFF/COOL Switch
• OFF - cooling and heating functions are defeated.
• HEAT - the selected room temperature is maintained by
cycling either in the heat pump mode or electric strip
heat. A PTH unit is switched from the heat pump mode to
electric strip heat when the coil temperature is 20°F or
when the heat pump cannot keep up with the heating load
and a two stage thermostat is used.
• COOL - the selected room temperature is maintained by
cycling the air conditioner.

aluminum fin stock.
Routine Scheduled Maintenance
To achieve continuing top performance and high efficiency,
establish a “once a year” cleaning/inspection schedule for the
unit. Take the unit out of the sleeve and thoroughly clean and
rinse. Be sure to include in the yearly cleaning the evaporator
coils, and condenser coils, basepan, and drain passages. Sched-
uled maintenance can be accomplished by either qualified local
maintenance staff or by an authorized servicer. They must
follow the instructions described in this manual.
Adverse Operating Conditions Maintenance
Units operating in dusty or corrosive locations; i.e. dusty con-
struction site or sea coast, must be cleaned more often. A
minimum of four (4) times a year will maintain proper opera-
tional conditions and protect unit components.
Wall Sleeve
Clean the wall sleeve while cleaning the unit. The caulking
around the sleeve should be checked to make sure that any
potential air and water openings around the sleeve are properly
sealed. Thewallsleeve’slevelshouldalsoberechecked. Proper
leveling for most installations are a ¼ bubble tilt to the outside
and level from right to left. Contact your sales person for
detailed maintenance or cleaning instructions.
Basepan and Condenser Coil
CAUTION
DO NOT USE COMMERCIAL GRADE COIL CLEANERS. SOME OF THESE
CLEANERS MAY CONTAIN ETHYLENE DIAMINE TETRACETIC ACID (EDTA)
WHICH CAN SHORTEN THE LIFE OF THE CONDENSER COIL.
Before cleaning the basepan and condenser coil, turn OFF unit
mode switch and disconnect power to the unit. To disconnect
power, either unplug the power cord at the wall outlet or
subbase, or disconnect power at the fuse box or circuit breaker.
1. Create a water-tight seal by tightly covering the entire

14
control panel area and fan motor with plastic. Creating
this seal prevents water from entering the control area or
the fan motor and damaging the unit.
2. Spray condenser coil and basepan down with water. Next
spray a mild biodegradable detergent such as Simple
Green™onto the condenser coil and basepan. Let set for
five (5) minutes.
3. Rinse condenser coil and basepan with water again.
NOTE: Ensure water pressure is no higher than that of an
ordinary garden hose and the water temperature no higher
than 120°F.
4. Tilt the non-compressor side of the unit up no higher than
45 degrees and allow water to drain out the other side of
the unit.
5. Remove excess water left in the basepan by wiping the
basepan with a dry cloth.
6. Remove the water-tight seal from the motor and control
panel area.
7. Reinstall unit back into wall sleeve.
8. Allow unit to dry for 24 hours before reapplying power.
When power is reapplied test unit for proper operation.
9. Place a non-acidic algaecide in the basepan to inhibit bac-
teria growth. Ensure the algaecide is compatible with wet
coil operation and is not corrosive to the coil.
CAUTION
HIGH PRESSURE AND HIGH TEMPERATURE CLEANING IS NOT RECOMMENDED.
DOING SO COULD DAMAGE THE ALUMINUM FIN STOCK AND ELECTRICAL
COMPONENTS.
Clearance Check
Clearances around the unit should also be checked to make sure
that the intake air and discharge air paths have not become
blocked or restricted. A minimum of eight inches clearance is
neededfrom unit to furniture , beds,or other objectsfor proper
operation. Restricted discharge or intake air will reduce the
unit’s operational performance. In severe airflow restrictions
damage can occur to unit components such as the compressor,
electric heater or fan motor.
OBTAINING SERVICE
In the event this unit requires repair or servicing beyond what is
covered in this manual, contact an authorized service organiza-
tion.
To obtain an authorized servicer, contact your sales representa-
tive or agency.
NORMAL OPERATING
SOUNDS AND CONDITIONS
Water trickling sounds
Water is picked up and distributed over the coil. This
improves the efficiency and helps with water removal.
Water dripping
Water will collect in the base pan during high humidity days.
This can cause overflow and drip from the outside of the unit.
Air sounds
The fan cycle switch sets the operational mode of the fan in
the ON position. The fan will run continuously whenever
power is applied in this mode. In the AUTO position, the fan
will cycle on and off with the compressor or electric heater.
Starting delay
You may notice a few minutes delay in the starting if you
try to restart the unit too soon after turning it off or if you
adjust the thermostat right after the compressor has shut
off. This is due to a built in delay to protect the compres-
sor.

DIAGNOSTIC MAINTENANCE
& STATUS REPORT
The Diagnostic Maintenance & Status Report provides detailed
information on PTAC control operation and operational status
includingpresentmodes, failures, airflow restriction warnings,
operating temperatures, and past failures. The lower right
hand dot on the center display flashes in this mode. In some
casesthe green LED located inthelower left hand corner ofthe
touchpad below the OFF key will also be lit. This Green LED
“StatusLight“onlyilluminatesifthereisanstatuscodethathas
beenactivatedandshouldbereviewed. Inmostcases,thislight
indicates that the indoor room filter is dirty should be cleaned
orreplaced. NOTE: Dirtyfilterscausetheunittoconsumemore
energy than normally needed to condition a room. Once the
filter has been cleaned or replaced, the LED should go out. If
the LED is still illuminated after the filter has been cleaned,
activate the Diagnostic and Status mode to view any active
codes. The unit may need additional cleaning or maintenance
of the evaporator or condenser coils. Please perform this step
before calling a servicer. A servicer should be called only if
