*
• 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.
*
• 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.

9-4. Temperature and humidity range

Permissible ranges of temperature and humidity are as
follows;
• Cooling / Dry operation
Outdoor temperature About –5°C to 46°C

If the unit is used under higher temperature conditions than
those noted here, the automatic protection circuit may
operate, interrupting 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.
• If the air conditioner is used outside of the specified
