◆Instructions for Use
Principle and Special Functions during Cooling Mode
Principle:
The air conditioner absorbs heat from indoor air and transmits it outdoors for discharge, hence to decrease the indoor
ambient temperature. The cooling capacity decreases with the rise of outdoor ambient temperature.
Anti-freeze Function:
If the air conditioner is running under low-temperature cooling mode, frost will appear on the surface of indoor heat
exchanger. When the temperature of indoor heat exchanger is decreased to 32°F or below, the microcomputer of indoor
unit will stop the compressor to protect the complete unit. A low ambient kit [not supplied] is required to make unit
operate at lower than 32°F.
Principle and Special Functions under Heating Mode
Principle:
＊ The air conditioner absorbs heat from outdoor air and transmits it indoors for emission, hence to increase the
air temperature in the room. The heating capacity decreases with the reduction of the outdoor ambient
temperature.
＊ It takes only a short time for this type of hot air circulating system to increase the indoor temperature.
＊ Use this air conditioner with other heating equipment if the outdoor temperature is extremely low.
Defrost:
＊ When the outdoor temperature is low but the humidity is high, the heat exchanger of outdoor unit may freeze
after the air conditioner has run for a period of time. This will decrease the heating effect. In this case, auto
defrost function will be activated and the heating mode will temporarily stopped for 8-10 minutes.
＊ Both the indoor fan and outdoor fan will be stopped during auto defrost.
＊ During defrost, the indicator on indoor unit will blink and steam might flow from the indoor unit. This is
caused by quick defrost other than fault.
＊ Heating mode will automatically resume upon completion of defrost process.
Anti-freeze Function:
Under heating mode, if the indoor heat exchanger fails to reach a specific temperature under the following conditions,
the indoor fan will not be started, so as to avoid blowing of cold air (within 3 minutes):
1. Start of heating mode. 2. End of auto defrost. 3. Heating under low-temperature environment.
★Conditions that the Air Conditioner will be unable to run normally:
The protection device will be activated within such temperature range as specified below, so that the unit will be shut
down.

◆Cleaning and Maintenance
•Be sure to cut off the power supply before cleaning the air conditioner; otherwise electric shock might
occur.
•Liquids on the air conditioner may cause the risk of electric shock. Make sure not to spray wash your
air conditioner in any case.
•Volatile liquids such as thinner or gasoline will cause damage to the appearance of air conditioner.
(Only use soft dry cloth or wet cloth soaked with neutral detergent to clean the air conditioner
cabinet).
Clean the front panel (Don’t remove the front panel when
cleaning).
When the indoor unit front panel is dirty, please use the cloth which is soaked in the warm water
under 104°F, then dry it and wipe the dirty places.
NOTE:
There are microcomputer components and circuit board on the displayer of the indoor unit front
panel, never let it dip in the water.
Clean filter (Approximately every three months)
Note: Clean the air filter more frequently if the air conditioner is used under dusty environment. To avoid
injury, do not touch the fins of indoor unit with your finger after removing
the filter.
① Remove the air filter
Hold the groove on two ends of the front panel. Along arrow direction,
pull with force to open the front panel for an angle. Then pull the air filter
downward for removal. See Fig. 5 (a, b, c)
② Clean the air filter
Wash the filter with vacuum cleaner or water. If the filter is too dirty,
wash with warm water (below 113°F) with neutral detergent. Then air dry it
at a cool place.
Note: To avoid discoloring or deformation, do not wash
with hot water over 113°F. Never dry on the fire, as the
filter may be burnt or deformed.

- 11 -
◆Cleaning and Maintenance
③Installing the air filter
Mount the air filter in the direction of the arrows. Then, clamp the cover
of front panel securely.
Check before Seasonal Use
① Check the air inlet/outlet on indoor and outdoor units for any blockage.
② Check the grounding cable for reliability.
③ Check the batteries of remote control for replacement.
④ Check the mounting frame of outdoor unit for damage. If damaged,
please contact the Authorized Service Center.
Check after Seasonal Use
①Cut off the power supply to air conditioner.
②Clean the filter and the indoor/outdoor unit.
③Clear off the dust and foreign particles on outdoor unit.
④If the outdoor unit is rusted, paint on the rusty portion to prevent corrosion.

◆Trouble-Shooting
Do not repair by yourself. Incorrect repair may cause electric shock or fire, so please contact the
Authorized Service Center for professional repair.
Fault Cause Analysis
Air conditioner does not run upon immediate restart after a
stop.
To protect the air conditioner upon immediate restart
after a stop, the microcomputer control will delay the
unit for 3 minutes before the air conditioner will run.
Air conditioner blows out a bad odor when it is initially
started.
The air conditioner itself has no bad odor. If any, it is the
bad odor accumulated from the environment.
Solution: Clean the air filter (Refer to Page 10). If the
problem persists please call the Authorized Service
Center.
You may hear a “water flowing” noise when the air
conditioner is running.
The noise you hear is the refrigerant in the system.
Sometimes a thin fog will flow out of the outlet when the air
conditioner is running under cooling mode.
This might occur when indoor temperature and humidity
are high. This is because the indoor air is quickly cooled
down.
After a period of time, the fog will disappear with the
decrease of indoor temperature and humidity.
You may hear a slight crack when the air conditioner is
started or stopped.
This is the sound of friction caused by expansion of panel
or other parts due to the change of temperature.

- 13 -
◆Trouble-Shooting
Fault Cause Analysis
Air conditioner does not run.
•Power failure?
•Circuit protection device tripped?
•The voltage is too high or too low?
(Refer to Page 15). (To be tested by
professional technicians).
•Timer function is correctly used?
(Refer to Page 7).
Air conditioner is poor in cooling (or heating) effect.
•Is temperature setting proper? ( Refer to Page 7)
•Is the air inlet or outlet of outdoor unit blocked?
•Is the air filter clogged by dust? ( Refer to Page
10).
•Are all doors and windows closed?
•Is air flow set to “LOW FAN”?
•Is any other heating source in the room?
Remote control cannot execute control.
•Remote control sometimes cannot execute control if
the air conditioner is subject to abnormal interference
or frequent switching of functions. To resume normal
operation, just pull out the battery and reinsert it
properly.
•Is remote within receivable range or blocked by any
obstacles? ( Refer to Page 7)
•Check the battery in remote control for power level.
If low power, replace the battery. ( Refer to Page
9)
•Is the remote control is damaged.
Water leaks from indoor unit. •Room air humidity is excessively high.
•Condensation water overflowing.
•Connection of indoor unit drain pipe is leaking.
Water leaks from outdoor unit. •Under cooling mode, water might condense on pipe
or pipe joint due to cooling.
•Defrosted water flows out under heating or defrost
(auto defrost) mode.
•Under cooling mode, water attached on heat
exchanger will drip.
Indoor unit has unusual noise. •The sound that the fan or compressor relay is
switching (close/open).
•Air conditioner may give out sounds under defrost
or when it is stopped. This is caused due to inverse
flow of refrigerant in the unit.

- 14 -
◆Trouble-Shooting
Fault Cause Analysis
No air blows out from indoor unit.
•When the temperature of indoor heat exchanger is
low during heating process, the indoor unit will stop
blowing to prevent blowing of cold air (within 3
minutes).
•Under dehumidify mode, the fan of the indoor unit
might be stopped to prevent evaporation of
condensing water and inhibit the rise of temperature.
Moisture exists on outlet grill.
•If the unit is run for extended periods under high
humidity condensation will be present at the outlets.
In the event of any of the following, please contact Authorized
Service Center.
