(5) Drain pump control
The drain pump works in COOL or DRY operation. When operation stops or changes to HEAT mode, the drain pump con-
tinues to operate for 3 more minutes. The drain pump does not work in check mode.
<Drain sensor>
When both the drain pump and unit are operating, the drain sensor detects the temperature. This temperature tells whether
the drain water level is above or under the drain sensor. If the drain water level rises above the drain sensor due to a drain
pump malfunction, the unit will stop operating in order to prevent drain from overflowing. The check code "P5" on the
remote controller will display this occurrence. When both of the following conditions are satisfied, the drain sensor is deter-
mined to be under water.
Though the drain sensor has been heated by the drain sensor heater for more than 40 seconds, its temperature rise is
less than 20 degrees.
The drain sensor temperature is below 63°C.
