OPERATING TIPS

In Event of Power Interruption

Should the power supply to the air conditioner be interrupted

●

by a power failure, the air conditioner will restart automatically

in the previously selected mode once the power is restored.

Notices

During use of the heating mode, the outdoor unit will oc-

●

casionally commence the defrost operation for brief periods.

During the defrosting operation, if the user sets the indoor unit

for heating again, the defrosting mode will continue, and the

heating operation will begin after completion of defrosting, with

the result that some time may be required before warm air is

emitted.

SELF-DIAGNOSIS

When "Er" in temperature indicator is displayed, inspection of the air conditioning system is necessary. Please consult authorized

service personnel.

ex. Self-diagnosis check

Use of other electrical appliances (electric shaver, etc.) or

nearby use of a wireless radio transmitter may cause the air

conditioner to malfunction. In this event, temporarily discon-

nect the power supply, reconnect it, and then use the remote

controller to resume operation.

During use of the heating mode, the top of the indoor unit

may become warm, but this is due to the fact that coolant is

circulated through the indoor unit even when it is stopped; it

is not a malfunction.
