AIR FILTER
The air filter behind the air intake grille should be checked and
cleaned at least once every two weeks.
HOW TO REMOVE THE FILTER
Hold the air filter by the tab at the top of the intake grille. And then
pull upwards.
TEST OFF ON
Storage
If you are not going to use the air-conditioner for a long
period, clean the air filters, evacuate the condensate from
the indoor unit through the drain hose at the unit back side.
Do not disconnect the flexible tube, unless you are obliged
to do it: in that case protect the open halves of the couplings
with the plugs supplied as accessories, that must be
tightened with a spanner. Do not put heavy objects on the
top of the unit, and protect it with a cloth or a plastic bag.
FILTER CLEANING
Use a vacuum cleaner to remove light dust. If there is sticky dust
on the filter, wash the filter in lukewarm, soapy water, rinse it
in clean water, and dry it.
TIPS FOR ENERGY SAVING
DO NOT:
●
Block the air intake and outlet of the unit.
If they are obstructed, the unit will not work well, and may be
damaged.
●
Let direct sunlight into the room. Use sunshades, blind or
curtain.
DO:
●
Always try to keep the air filter clean. A clogged filter will impair
the performance of the unit.
●
To prevent conditioned air from escaping, keep windows, doors
and any other openings closed.

CONDENSATE DRAIN PIPE
TROUBLESHOOTING
• The use of portable telephones near the air-conditioner may
cause disturbance to its normal operation and must be avoided.
In case abnormal operation is noticed, (OPR operation lamp
lights but outdoor unit will not run) to restore normal operation
turn-off electric supply for 60 seconds at least, by disconnecting
the main switch or the wall plug, then start again the air-
conditioner.
• The lighting-up of the lamp, together with the stop of the
air conditioner for a short time, 1 - 2 minutes, are due to the
exceeding condensate drainage. Otherwise, the lighting-up of
the same lamp and the definitely stop of the air conditioner
indicate that the condensate pump is not working or that the
condensate drain pipe in the flexible connection pipe is
obstructed; in this case contact the AFTER SALE SERVICE.
In case of emergency the air conditioner can work by draining
the condensate from the back little pipe into a rather short
container, extract the little pipe and remove the cap.

following points before requesting service.
If it still does not work properly, contact your dealer or service
center.
