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 manufacturer.
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
manufacturer.
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.
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.
8.2 Maintenance & Upkeep Of Outdoor Unit
8.3 Operation Required Before Leaving The Air
Conditioner Idle For A Long Period:
8.4 Startup After A Long Period Out Of Service
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.
The following phenomena do not indicate exception of air
conditioner
The system does not run.
After pressing the ON/OFF button, the system does not run
immediately.
If the RUN indicator is on, it indicates the air conditioner runs in
the normal status.
It does not run immediately because the safety device in the
system is active to prevent overload.
Three minutes later, the air conditioner compressor will run
automatically.
If the RUN indicator and the Defrost/Preheat indicator are on, it
indicates you have selected the heating mode. At the beginning
after startup, since the compressor does not run, the tempera-
ture of the indoor unit is too low. See the chapter headed
“Cooling/Heating/Supply Air Operation Procedure".
The indoor unit gives out white aerosol
This phenomenon may occur when the indoor relative humidity
is too high and the unit runs in the cooling mode (in a place
where there is much oil mist or dust).
If the internal stain of the indoor unit is heavy, the temperature in
the room will be distributed unevenly. In this case, the interior of
the indoor unit must be cleaned.
Contact the local distributor or the aftersales service center of
manufacturer to inquire about the methods of cleaning the
indoor unit. This job must be performed by professional
maintainers.
This phenomenon may also occur when the air conditioner
shifts from defrosting operation to heating operation.
That is because the moist generated by defrosting is expelled as
steam.
Noise of air conditioner
When the air conditioner runs in the cooling, dewetting or
heating mode automatically, grave continuous sizzles may
occur.
That is the sound of flow of refrigerant between the indoor unit
and the outdoor unit.
The sizzles may be heard shortly after the unit stops running or
when the unit runs in the defrost mode. That is the sound raised
because the refrigerant stops flowing or changes the volume of
flow.
Squeak may occur when the air conditioner starts or stops
running. That is the sound raised because the plastic assem-
blies inflate or deflate when the temperature changes.
