7. AIR FILTERS CLEANING
Cleaning the air filter
The air filter can prevent the dust or other particulate from going inside. In case of blockage of the
filter, the working efficiency of the air conditioner may greatly decrease.
Therefore, the filter must be cleaned once every month during long time usage.
If the air conditioner is installed in a dust place, clean the air filter frequent.
If the accumulated dust is too heavy to be cleaned, please replace the filter with a new one
(replaceable air filter is an optional fitting).
(1) Open the air-in grill
Push the grill switches towards the middle simultaneously as
indicated in.
Then pull down the air-in grill.
The control box cables ,which are originally connected with the
main body electrical terminators must be pulled off before
doing as indicated above.
(2) Take out the air-in grill
( together with the air filter shown in )
Pull the air-in grill down at 45 and lift it up to take out the
grill.
(3) Dismantle the air filter.
(4) Clean the air filter
Vacuum cleaner or pure water may be used to clean the air
filter. If the dust accumulation is too heavy , please use soft
brush and mild detergent to clean it and dry out in cool place.
The air-in side should face up when using vacuum cleaner.
The air-in side should face down when using water.
(5) Re-install the air filter.
(6) Install and close the air-in grill in the reverse order
of step 1 and 2 and connect the control box cables
to the corresponding terminators of the main body.
8- INDOOR UNIT CLEANING
Before indoor unit cleaning, turn the system off and switch the mains supply off.
Use only a clean, damp and soapy cloth.
Do not use water to flush the unit.
Do not use flammable liquid, solvents or abrasive powders: these
can damage the casing.
Use household neutral detergent to clean the fingerprints or oil
stains.
Avoid any contact with sources of heat, as hot air can damage the
unit casing.
Clean the infrared control using a damp cloth.
