Left and Right Control
If you want to adjust the direction of the discharge air to left or right, adjust the vertical
louver with the handle after opening the flap.
HANDLE
NOTE
• Please do not fix the flap at position
for a long time, as this position minimizes air
circulation resulting in uneven room temperature.
• Please avoid the discharge air being directed towards the occupants for a long period
of time.
• Do not adjust the flap by the hand during SWING operation because it may damage
the air swing function.
(6) Unit Protection Devices
3 min. Time Delay and 3 min. minimum operation time of compressor
– In normal operation, there is a time delay of three minutes (42HQG024/HWG605H : 5
minutes during heating mode) between compressor turning off and turning back on includ-
ing initial power up.
– After compressor turns on, it will operate for 3 minutes independent of temperature condi-
tion.
Time Delay When changing the operation mode
– The unit operates immediately when changing mode from ON to OFF or from OFF to ON,
or indoor fan speed without the change of operation mode.
– The unit operates after 10-second time delay when changing operating mode.
– The unit operates after 3-second time delay when changing the set temp. without the
change of operation mode.
Frost Prevention of Indoor Unit.
– When the unit operates at low ambient temperature, frost may appear on the evapo-
rator. When the indoor coil temperature is less than 0ºC for 10 minutes of continu-
ous compressor operation from the start, microcomputer of the unit stops the compres-
sor to protect the unit from the frost.
– The system performs this function only in COOL and DRY mode.
– The control procedure for indoor coil freeze protection.
1) The compressor and outdoor fan turn off.
2) Indoor fan operates according to user set speed.
3) The normal operation returns when the indoor coil temperature is greater than or equal
to 7ºC.
