box cables to the corresponding terminators of the main body.
CLEANING THE AIR OUTLET AND THE PANEL
• Use a dry and soft cloth to wipe it.
• Pure water or mild detergent may be used if it is very dirty.
CAUTIONS
• Do not use benzene, thinner, polishing power, or similar solvents for cleaning. These may
cause the surface to crack or deform.
• To avoid the risk of electrical shock or fire, do not let water fall into the indoor unit.
• Never wipe the air flow louver violently.
• An air conditioner without air filter can not expel the dust out of the room, which would cause
malfunctions by accumulation.
MAINTENANCE OF THE OUTDOOR UNIT
1. Injures may happen by improper operations because of the sharp blade of some plates and
the freezer.
2. Check the air outlet and the air inlet of the outdoor unit regularly to ensure that they are not
choked by filth or soot.
3. The coil and other parts of the outdoor unit should also be checked regularly. Please contact
with your local dealer.
IF YOU DO NOT PLAN TO USE THE UNIT FOR A LONG TIME
• Operate the fan for about half a day to dry the inside of the unit.
• Turn off the unit with the "ON/OFF" button on the remote controller,then disconnect the power.
NOTE
• When the power switch is connected, some energy will be consumed, even if the unit is not
in operation. So please disconnect the power to save energy.
• A degree of filth will be accumulated due to certain performance after several seasons of
operation. So special maintenance is advised.
• Take out of the batteries from the remote controller.
RESTART AFTER A LONG TIME
1. Check before operation
• Check the air outlets or inlets of the indoor/ outdoor unit are not blocked.
• Check the grounding wire is not broken off and is connected well.
2. Restore the air filter and the front panel
The air filter and the front panel must be fixed to the original position after having been cleaned.
3. Connect the main power switch
To protect the air conditioner, power should be provided 12 hours before operation. Then the
OPERATION lamp on the control box of the indoor unit will flash once a second.
