OPERATING TIPS
Notice
*l During use of the heating mode, the outdoor unit will
occasionally 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 "EE" in Temperature Display is displayed, inspection of the air conditioning system is necessary. Please consult
authorized service personnel.
