2-1. Drain pump control

 

 

 

 

 

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

 

 

 

following conditions is satisfied:

 

 

 

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

 

 

 

 

another operation mode (FAN).

 

 

 

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

 

 

using the liquid level detection method given below.

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

room temperature [ -18°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.)

2-2. 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 [ -18°F

3 Indoor piping (liquid piping) temperature or indoor room temperature is at the short or open level temperature.

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

3. Vane

Same as the control performed during the COOL operation, but with no restriction

(up/ down vane change)

on the vane's downward blow setting.
