OPERATING TIPS
AUTO Restart
In Event of Power Interruption
If the power supply to the air conditioner is interrupted by a
power failure, the air conditioner will restart automatically in
the previously selected mode once the power is restored.
Notice
* 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 Display is displayed, inspection of the air conditioning system is necessary. Please consult
authorized service personnel.
TEMPERATURE AND HUMIDITY RANGE
Permissible ranges of temperature and humidity are as follows:
Cooling / Dry
Operation
Heating
Operation
If the unit is used under higher temperature conditions than those noted here, the automatic protection circuit may operate, interrupt-
ing the operation.
If the unit is used under lower temperature conditions than those noted here, the heat exchanger may freeze, causing water leakage
or other malfunction.
Do not use the air conditioner for any purpose other than room cooling/dry, room heating, or fan.

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.
