HELPFUL INFORMATION
Random Auto Restart
• Operation will automatically
resume under the previous
operation mode.
• If the unit was set to TIMER
mode, operation will not resume
automatically.
Timer Setting
• When power failure occurs, the
timer setting is canceled. Once
power returns, reset the timer.
ENERGY SAVING HINTS
• Setting the temperature 1°F higher save
10% electricity costs.
• Clean the air filter every 2 weeks. Regular
cleaning of the air filter preserves efficiency.
• Keeping openings closed keeps cool air in
and hot air out.
• Avoid direct sunlight and heat.
• For health reasons do not overcool your
room.
• Your air conditioner’s cooling capacity
should match your room size.
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 (refer to
Remove the front intake grille
procedures). 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. (Annual check is not covered under warranty)
• 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?
•
Are the remote control batteries weak?
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 service center.
