interpretation or misuse of the information provided, nor does it assume any
liability in connection with its use.
The safeguards and warnings indicated in this manual do not cover all possible
conditions which may occur. Common sense, caution, and care must be
exercised.
To prevent electric shock, always unplug an appliance from the power supply before attempting
any service.
Disconnect the power cord by grasping the plug, not the cord.
Do not bypass, cut, or remove the grounding plug.
Prevent water from spilling onto electric elements or the machine parts.
Always refer to the rating label on the appliance for rated current and voltage.

6 Modes and Operating Conditions
6.1 Cooling mode
When Tambient ≥ Tpreset +1ºC(2ºF) the unit operates in cooling mode. The compressor runs and the
indoor fan operates at the set fan speed. If the indoor fan operates at high or medium speed, the outdoor
fan operates at high speed. If the indoor fan operates at low fan speed, the outdoor fan operates at low
speed.
When Tambient ≤ Tpreset -1ºC(2ºF) the compressor and outdoor fan stop, while the indoor fan operates
at the set fan speed.
When Tpreset-1ºC(2ºF) < Tambient < Tpreset+1ºC(2ºF) the unit stays in the original operation mode.
Under cooling mode the 4-way valve is de-energized. The temperature can be set between 61 and 86ºF
(16-30ºC).
6.2 Dry mode
Under this mode the set temperature and ambient temperature won’t be displayed. The indoor fan
operates at low fan speed. The compressor and outdoor fan operate continuously.
6.3 Heating mode (AP13500HG only)
When Tambient ≤ Tpreset+3ºC(6ºF) the unit operates in heating mode. The 4-way valve energizes, the
compressor runs, and the indoor fan operates at the set fan speed. If the indoor fan operates at high or
medium speed, the outdoor fan operates at high speed. If the indoor fan operates at low speed, the
outdoor fan operates at low fan speed.
When Tpreset+3ºC(6ºF) < Tambient < Tpreset+5ºC(10ºF) the unit stays in the original operation mode.
When Tambient ≥ Tpreset+5ºC(10ºF) the compressor and outdoor fan stop. The 4-way valve will de-
energize after the compressor has stopped for 2 minutes. The indoor fan operates to disperse any
residual heat.
In heating mode the temperature can be set between 61 and 86ºF (16-30ºC).
6.4 Fan mode
In this mode the set temperature and ambient temperature won’t be displayed. The indoor fan operates at
the set fan speed.
6.5 Auto mode
Under auto mode standard cooling Tpreset=77ºF(25ºC); standard heating Tpreset=68ºF(20ºC)
6.5.1 AP13500G
When Tambient > 79ºF(26ºC) the unit runs in cooling mode. When Tambient < 68ºF(20ºC) the unit runs
in fan mode.
If the unit is operating in fan mode and 68ºF(20ºC) ≥ Tambient ≥ 73ºF(23ºC), the unit will stay in fan
mode. If the is not running in fan mode it will change to dry mode.

14
6.5.2 AP13500HG
When Tambient > 79ºF(26ºC) the unit runs in cooling mode. When Tambient < 68ºF(20ºC) the unit runs
in heating mode.
If the unit is operating in heating mode and 73ºF(23ºC) ≥ Tambient ≥ 68ºF(20ºC), the unit will stay in
heating mode. If the unit is not operating in heating mode the unit will change to dry mode.
6.6 Timer Mode
Timer ON is set with the unit OFF. The unit will turn ON when the set time is reached. The timer set range
is 0.5-24hr in 30-minute increments.
Timer OFF is set with the unit ON. The unit will turn OFF when the set time is reached. The timer set
range is 0.5-24hr in 30-minute increments.
6.7 Sleep Mode
Press the Sleep Button to enter sleep mode. The Sleep Mode can be activated when in Cool Mode or
Heat Mode and will not operate when in Fan Mode. When operating in Cool Mode, the Sleep function will
slowly raise the Temp Control by 4° Fahrenheit over the initial 2 hour Sleep Mode period. When operating
in Heat Mode (AP13500HG only), the Sleep function will slowly lower the Temp Control by 4° Fahrenheit
over the initial 2 hour Sleep Mode period. When the Sleep Mode is active, the LCD will continue to display
the Sleep Mode status.
6.8 Freeze Prevention Mode
Under freeze prevention mode the compressor stops running and the indoor fan operates at set fan
speed. After the evaporator thaws the unit will return to normal operation.
6.9 Compressor Protection Mode
If power is interrupted, the compressor will only restart after a 3 minute delay.

7 Troubleshooting
7.1 Troubleshooting Guide
Problem
Possible Cause
Solution
Unit does not turn on.
Wall plug is disconnected.
Insert plug firmly into proper wall outlet.
House fuse blown or circuit breaker
tripped.
Replace fuse with time delay type or reset circuit
breaker.
Power cord is tripped.
Press the RESET button on the power cord. If
power cord is damaged replace power cord.
Unit is turned OFF.
Turn unit ON and set to desired setting.
Ribbon cable to control panel is
disconnected.
Remove outer shell and reconnect cable.
Loose or disconnected wiring on main
PCB.
Remove outer shell. Check all connections to the
PCB and reconnect any loose or disconnected
leads.
Condensate water tray is full and/or
display shows H8 error code.
Drain condensate water. Make sure water level
switch is operating correctly and not stuck in “full”
position or being interfered with.
Ambient temperature sensor has
malfunctioned and/or display shows
F1 error code.
Check sensor wiring connection on PCB. Replace
sensor if defective.
Poor cooling (or
heating)
performance.
Room temperature is below
61ºF(16ºC) or above 86ºF(30ºC).
Cooling will not occur until room temperature rises
above 61ºF(16ºC.) Heating will not occur until
room temperature falls below 86ºF(30ºC).
Fan speed is set too low.
Increase fan speed to improve air flow.
Set temperature is too high (or too
low.)
Set to a Lower (or higher) temperature.
Filter is dirty.
Clean filter.
Refrigerant leak. Display shows F0
error.
Find leak and repair. Recharge with refrigerant.
Evaporator is frosted.
The unit needs to defrost and will resume normal
operation after defrost mode is finished.
Unit continues to
operate after water
tray is full or water full
protection (H8 error)
occurs frequently.
Water level switch is open or short
circuited.
Check water level switch connections or replace
water level switch if defective.
Water level switch is stuck in “empty”
position.
Make sure water level switch is operating correctly
and not stuck or being interfered with.
Water flinger motor is defective.
Replace water flinger motor.

16
Fan louvers do not
swing.
Wire connections faulty.
Check wire connections. Repair or tighten any
broken or loose connections.
Fan swing motor damaged.
Replace motor.
Sounds or vibration.
When unit is turned on or off the outer
shell “pops” or “clicks.”
Normal sound. Outer shell is contracting or
expanding and will stop after a few minutes.
When unit is turned on or off “boiling”
or “running water” is heard.
Normal sound. The cause is refrigerant flowing
inside the system and will stop after a few minutes.
Foreign objects inside the unit are
interfering with fans or other moving
parts.
Remove foreign objects.
Compressor vibration.
Tighten bolts holding compressor to chassis.
Room too cold (or too
hot.)
Set temperature is too low (or high.)
Adjust the set temperature.
