NOTE: For multi-split type air conditioners, one outdoor unit can be matched to different
types of indoor units. All of the pictures in this manual are for demonstration purposes
only. Your air conditioner may be slightly different, if similar in shape. The following pages
introduce several kinds of indoor units that can be matched with the outdoor units.

Operating Conditions

Use the system under the following temperatures for safe and effective operation. If the air
conditioner is used under different conditions, it may malfunction or become less efficient.

Features
Protection of the air conditioner
Compressor protection
• The compressor cannot restart for 3 minutes
after it stops.
Anti-cold air (Cooling and heating
models only)
• The unit is designed not to blow cold air on
HEAT mode, when the indoor heat exchang-
er is in one of the following three situations
and the set temperature has not been
reached.
A) When heating has just started.
B) During defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running
when defrosting (Cooling and heating
models only).
Defrosting (Cooling and heating models
only)
• Frost may be generated on the outdoor
unit during a heat cycle when outdoor
temperature is low and humidity is high re-
sulting in lower heating efficiency in the air
conditioner.
• Under these conditions, the air conditioner
will stop heating operations and start de-
frosting automatically.
• The time to defrost may vary from 4 to 10
minutes, depending the outdoor tempera-
ture and the amount of frost buildup on the
outdoor unit.
