8. MAINTENANCE & UPKEEP
8.1 Importants
Only the professionals can perform repair.
Before performing operation for the electric connectors or
cleansing the filter, turn off the main power switch.
Do not use water or air with a temperature higher than 50°C to
cleanse the filter or panel.
Check and maintain the ventilating slot once every half years,
wash and maintain with corresponding disinfection shall
process once
every two years are recommended. The filter can expel dust and
other particles in the air. If it is blocked, the effect of the air
conditioner will be degraded.Therefore, clean it every another
two weeks if you use the air conditioner for a long period.
If the indoor unit is installed in a place with heavy dust, clean the
filter more often.
If the stain is heavy and difficult to clean, replace the filter (the
substitute filter is an optional assembly in the sale).
Do not replace the power cable without permission. If the power
cable is damaged, specialized power cable must be used as
substitute. No not repair the air conditioner without permission.
The foregoing operations must be performed by the local
distributor or aftersales service office of manfacturer.
8.2 Maintenance & Upkeep Of Outdoor Unit
The edge of some sheet metal assemblies and the fin of the
condenser are very sharp. Incorrect operation may cause harm.
Be cautious when cleaning them up.
Check the air inlet and outlet of the outdoor unit periodically to
see whether they are blocked by stain or lampblack.
Contact the distributor or the aftersales service center of
manfacturer.
8.3 Operation Required Before Leaving The Air
Conditioner Idle For A Long Period:
Let the air conditioner run in the air supply mode for about half a
day, and let its interior be fully dry.
Switch off the power by the button in remote controller, and then
cut off the power supply.
When the main power switch is turned on, a certain extent of
electric power is consumed even if the air conditioner does not
run. Turning off the main power switch can save energy.
Remove the batteries out of the remote controller.
After the air conditioner has been in service for several seasons,
foreign substance accumulates inside the unit to an extent
dependent on the working conditions. Therefore, shut down the
air conditioner through the ON/OFF button of the remote control-
ler, and then cut off the power supply.
8.4 Startup After A Long Period Out Of Service
Check the following issues:
Check whether the air inlet or outlet of the indoor unit and
outdoor unit is blocked. Remove foreign substance if any.
Check whether the ground wire is connected properly.
Check whether the condensate water is discharged normally.
(Cooling operation season)
Check whether the insulation work of refrigerant circuit and
ventilating duct is on sound status.
Check whether the installing seat is corroded or rusted.
Startup
Connect the indoor unit 12 hours after connect the outdoor unit
to power supply.
Switch on the power control of remote controller or wire control-
ler, and than startup the air conditioning.
