Cleaning the air inlet grille
1. Remove the air inlet grille.
Hold the both sides of the air inlet grille and open
upward.
Move the center arm to the left and remove the grille.
2. Wash it with water using a soft sponge or towel.
(Do not use metallic scrubbing brush or other hard
brushes.)
• Use of such hard objects will cause scratches on the
surface of the air inlet grille, and the coating to peel
off.
• If very dirty, clean the air inlet grille with a neutral
detergent, and rinse it off with water after removing it
from the unit.
3. Wipe out water from the air inlet grille and dry.
4. Fit the left and right arms of the air inlet grille to the
shafts on the two sides of the air conditioner and push in
completely, and then push in the center arm.
5. Check that the center arm has been completely inserted
and close the air inlet grille.
• Push the arrow locations (four) at the bottom of the air
inlet grille to check whether the grille is completely
closed.
AIR CONDITIONER OPERATIONS AND PERFORMANCE
3 minute protection function
A protection feature prevents the air conditioner from being activated for approximately 3 minutes when it is
restarted immediately after operation or when the power supply switch is turned on. This will protect the
machine.
Heating operation characteristics
Preheating operation
The air conditioner will not deliver warm air immediately after it is started.
Warm air flows out after approximately 5-minutes when the indoor heat exchanger warms up.
(The PRE.-DEF. lamp is on during the preheating operation.)
Warm air control
When the room temperature reaches the set temperature, the indoor fan speed is automatically reduced to
prevent cold draft.
The outdoor unit will stop.
Defrosting
If the outdoor unit is frosted during heating operation, defrosting is started automatically (for approximately 5
to 10 minutes). To maintain the heating effect, the PRE.-DEF. lamp is on.
• The fans on the indoor and outdoor units stop during the defrost operation.
• During defrost operation, defrosted water drains from the bottom plate of the outdoor unit.
