Operation ranges
The table below indicates the temperature and humidity ranges the air
conditioner can be operated within. Refer to the table for efficient use.
Maintaining your air conditioner
If the air conditioner operates in cooling mode for long period of time in high humidity area, dew may be formed.
If the outdoor temperature goes down to -5°C, heating capacity may decrease as much as 60%~70% of
specified capacity according to the using conditions.

Internal protections via the unit control system
This internal protection operates if an internal fault occurs in the air conditioner.
Type
Description
Against cold air
The internal fan will be off to against cold air when the heat pump is heating.
De-ice cycle
The internal fan will be off to defrost ice when the heat pump is heating.
Anti-protection of
internal battery
The compressor will be off to protect internal battery when the air conditioner operates
in Cool mode.
Protect compressor
The air conditioner does not start operating immediately to protect the compressor of
the outdoor unit after it has been started.
• If the heat pump is operating in Heat mode, De-ice cycle is actuated to remove frost from an outdoor unit that may
have deposited at low temperatures.
The internal fan is switched off automatically and restarted only after the de-ice cycle is completed.
Checking before use
The standardizedtemperature for heating is 7˚C. If the outdoor temperature drops to 0˚C or below, the heating capacity can
be reduced depending on the temperature condition.
If the cooling operation is used at over 32˚C(indoor temperature), it does not cool at its full capacity.
