5 Modes and Operating Conditions
5.1 Terms and Definitions
TA: Ambient indoor temperature.
TS: Set temperature.
5.2 Cooling Mode
The cooling temperature can be set from 61 to 89℉(16 to 32℃.)
The timer function works in cooling mode.
The compressor will run when the difference between the set temperature and the actual ambient
room temperature conforms to the chart below:
When TA≤TS (for 1 minute) the compressor turns off.
When TA>TS+2℉the compressor turns on.
5.3 Fan Only Mode
If the temperature can’t be controlled by the selected mode and the room ambient temperature is
shown on the display the unit will default to fan only mode.
The readout can only display a temperature of 32 to 99 ℉(0 to 37℃.) lf the temperature is out of that
range the display will show LO or HI.
The Timer function works in fan only mode.

5.4 Dehumidify Mode
In this mode, the air conditioner will operate as a dehumidifier. Because the conditioned space is
closed or sealed, some degree of cooling will continue to occur.
If the room temperature is below 77ºF, the fan will always run on low speed while in dehumidify
mode.
If you do not use the exhaust hose in Dehumidifying mode, you must manually drain the water from
the unit. Additionally, the ambient temperature in the room will probably rise by a few degrees if you
do not use the exhaust hose.
You will be not be able to change the thermostat temperature or fan speed while in dehumidify mode.
5.5 Heat Mode (AP12000HS Only)
Your air conditioner can work as a heat pump and provide supplementary heating.
It must be vented so that it can expel the cold air out of the exhaust.
Press the Mode button until the LED indicator next to “Fan” lights up red.
5.6 Overflow Prevention
When water is detected in the reservoir for 3 seconds overflow prevention will occur.
The water light turns on.
5.7 Compressor Protection
If power is interrupted, the compressor will only restart after a 3 minute delay.

water light is on.
Drain condensate water. Make sure water level
switch is operating correctly and not stuck in “full”
position or being interfered with.
Unit does not blow
cold air.
Room temperature is below
61ºF(16ºC.)
Cooling will not occur until room temperature rises
above 61ºF(16ºC.)
Unit is not in cooling mode.
Set the unit to cooling mode –blue light is on.
Set temperature is too high.
Set to a Lower temperature.
Air filter is dirty.
Clean filter.
Exhaust air duct is installed
incorrectly or blocked.
Connect exhaust duct so if functions correctly. Clear
blockage.
Refrigerant leak.
Find leak and repair. Recharge with refrigerant.
Evaporator is frosted.
The unit needs to defrost and will resume normal
operation after it is finished.
Unit blows cold air
but does not lower
room temperature.
Fan speed is set too low.
Increase fan speed to improve air flow.
Exhaust air duct is not installed, is
installed incorrectly or blocked.
Connect exhaust duct so if functions correctly. Clear
blockage.
Room area is too large.
Reduce room size, add another unit or larger unit.
Open windows or doors.
Close all open windows and doors.
Ambient temperature is too high.
The unit may not work if the room temperature is
above 90°F.
Room has too many heat sources.
Remove or shut off additional heat sources. Close
curtains or blinds to minimize the amount of direct
sunlight entering the room.

17
Filter is dirty.
Clean filter.
The condenser coils are dirty.
Carefully vacuum the coils clean.
Unit continues to
operate after water
tray is full or water full
protection 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.
Unit leaks.
Drain plug is removed.
Attach the drain plug.
Base plate is cracked.
Replace base plate.
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.
Unit is not level.
Make sure unit is on a level surface.
Compressor vibration.
Tighten bolts holding compressor to chassis.
Room too cold.
Set temperature is too low.
Adjust the set temperature.
