CARE AND MAINTENANCE
Always turn off the air conditioner and the main power supply before clean the unit.
Switch off the power supply if the unit is not going to be used for a long period of time.
CAUTION
Clean the cabinet, front grille with a mild soap or detergent and lukewarm water.
The front intake grille can be easily removed for cleaning purposes. Gently wash it with water and a sponge.
The filter can be easily cleaned using a vacuum cleaner. Vacuum the front of the filter and then wash the rear with water. If it is
badly soiled, wash with a mild household detergent.
It is recommended to replace the (part no.CZ-SF6P) every 3 months.
Do not clean with benzene, thinner, scouring powder or cloth soaked in caustic chemicals.
If the unit is extremely dirty, heat transfer is less efficient and the unit may not cool effectively. Contact your nearest servicenter
for an annual check.
If the air filter becomes clogged with dust, the cooling capacity will drop, and 6% of the electricity used to operate the air
conditioner will be wasted.
NOTE
Do not dry the front panel or the air filter in direct sunlight. (Exposure to direct sunlight may discolor or deform the panel.)
PRE-SEASON INSPECTION
Is the discharged air cold?
After 15 minutes of operation, it is
normal for the temperature
difference between intake and outlet
air to be more than 14.4°F for
cooling.
Are the air intake and outlet vanes
of the indoor and outdoor side
obstructed?
RECOMMENDED INSPECTION
Usage over several seasons will reduce performance as the
unit becomes dirty.
A dirty unit may produce foul odors and dust may clog the
dehumidifying drainage.
Seasonal inspection is recommended in addition to regular
cleaning. Consult your nearest servicenter.
