•
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.
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.
