21. OFF DEFROST OPEARTION CONTROL

01-15

1. OFF DEFROST OPERATION CONDITION

When operation stops in the [Heating operation] mode, if frost is adhered to the outdoor unit heat

exchanger, the defrost operation will proceed automatically. In this time, if indoor unit operation

lamp flashes slowly (7 sec ON / 2 sec OFF), the outdoor unit will allow the heat exchanger to defrost,

and then stop.

In heating operation, the outdoor heat exchanger temperature is less than 24.8°F(-4°C), and

compressor operation integrating time lasts for more than 30 minutes.

OFF Defrost Flow Chart

and

Compressor integrating operation :

Over 30 minutes

Defrost start

Defrost Indicater:

[Operation lamp]

7 sec ON / 2 sec OFF

Outdoor heat exchanger temperature : Over

55.4°F(

2. OFF DEFROST RELEASE CONDITION

Release Condition

Outdoor heat exchanger temperature is higher than 55.4°F(13°C)

Compressor operation time has passed 15 minutes.

( Table 18 : OFF Defrost Release Condition )

OFF defrost operation is released when the conditions becomes as shown in Table 18.
