<Outline>

Defrosting carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor heat exchanger
temperature must be more than its fixed value when finishing.

<Detail>

•

Conditions for Starting Defrost

The starting condition must be made with the outdoor air temperature and heat exchanger temperature.

Under the conditions that the system is in heating operation, 6 minutes after the compressor is started and

more than 44 minutes of accumulated time pass since the start of the operation or ending the defrosting.

•

Conditions for Canceling Defrost

The judgment must be made with heat exchanger temperature.( 4 °C to 22 °C)

7-2-8. Defrost Control

<Outline>

Fan control is carried out according to the following priority.
(1) Fan ON control for electric component cooling fan
(2) Fan control when defrosting

(3)

Fan OFF delay when stopped

(4)

ON/OFF control in cooling operation

(5) Tap control when drooping function is working.

(6)

Fan control in forced operation

(7)

Fan control in indoor / outdoor unit silent operation

(8)

Fan control in powerful mode

(9) Fan control in normal operation

<Detail>

Fan OFF Control when Compressor is Stopped.

•

Fan OFF delay for 60 seconds must be made when the compressor is stopped.

Tap Control in indoor / outdoor unit silent operation

(1) Cooling Operation

When the outdoor air temperature is lower than 37 °C, the fan tap must be set to L.

(2) Heating Operation

When the outdoor air temperature is higher than 4 °C, the fan tap must be turned to L.
