1-1. Drain pump control

 

 

The drain pump turns ON for the specified amount of time when any of the

 

 

following conditions is satisfied.

 

 

(regardless of whether the compressor is ON or OFF)

 

 

1 ON for 3 minutes after the operation mode is switched from COOL or DRY to

 

 

another operation mode (HEAT mode).

 

 

2 ON for 6 minutes after the drain sensor is determined to be submerged using the

 

 

liquid level detection method given below.

 

 

3 ON for 6 minutes after indoor piping (liquid piping) temperature – indoor room

 

 

temperature [ 14°F, and the drain sensor input is at the short or open level.

 

 

(If condition 2 or 3 is still being met after the drain pump has been turned ON for 6

 

 

minutes, the drain pump is kept ON for a further 6 minutes.)

 

1-2. Liquid level detection method

The liquid level is detected by determining whether or not the drain sensor is submerged, based on the amount the temperature rises after self-heating the sensor.

This process is performed if any of the following conditions is satisfied:

1Drain pump is ON.

2Indoor piping (liquid piping) temperature – indoor room temperature [ 14°F (except during defrosting)

3Indoor piping (liquid piping) temperature or indoor room temperature is at the

short or open level temperature.

4Every 1 hour after the drain pump has been switched from ON to OFF.
