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.

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,

(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 blinking OPERATION lamp, together with the stop

•

of the air conditioner for a short time are due to the

exceeding condensate drainage. (see table "AUTO-

DIAGNOSIS")

If the OPERATION lamp goes on blinking and the air

conditioner definitely stops means 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.

If your air conditioner does not work properly, first check

•

the following points before requesting service.

If it still does not work properly, contact your dealer or

service center.
