When defrost operation 

begins, frost has formed 

on the outdoor unit 

(when the ambient air 

temperature is low).

Defrost operation begins based on outdoor heat 

exchanger temperature and outdoor air 

temperature conditions.

Non-stop defrost (Refer to Fig. 1)

1. After HEAT operation begins, the temperature 

of the outdoor heat exchanger is at or below the 

L1 line for 35 minutes.

(If outdoor air temperature is less than –3 °C,

the time is 48 minutes) 

2. After HEAT operation begins, the temperature 

of the outdoor heat exchanger is at or below the 

L2 line for 120 minutes.

The 4-way valve remains ON during defrost.

The outdoor fan stops and the solenoid 

valve turns ON, allowing the refrigerant to

bypass the indoor unit.

Indoor fan : Stopped
Outdoor fan : Stopped
Compressor : 80 Hz
Solenoid valve (for hot gas bypass): ON
4-way valve : Remains ON
Operation lamp : Red and orange ON 
                            alternately

Defrost release

Indoor fan turns ON.
After 10 seconds, the solenoid valve 

(for hot gas bypass) turns OFF.

When the cold air feel has disappeared, 

the indoor fan starts and gradually increases 

speed until it reaches the set speed.

STOP
[Clean defrost]
Defrost is performed 

when the outdoor unit is 

stopped, and the 

temperature of the 

outdoor unit coil is at or 

below the L1 line. 
(Refer to Fig. 1.)

All indicator lamps turn OFF. The indoor and 

outdoor units stop.

The operating frequency during defrost is 

80 Hz. (Frequency is lowered if the current 

peak cut-off function is activated.)
The maximum length of a single defrost 

operation is 12 minutes.
For the outdoor heat exchanger temperature 

conditions for ending defrost, refer to Table 1.

Operation is restarted 

within 4 hours (only when 

AUTO mode is selected 

with the remote 

controller).

Within 4 hours after operation was stopped, it is 

assumed that there has been no significant 

change in the indoor and outdoor temperatures, 

and the previous conditions (HEAT) are stored.

Starts operating in the same operating mode 

(HEAT) and with the same temperature 

settings as before operation was stopped.

Operation starts after 4 

hours or more have 

passed.
