Special Features
Dry mode
•
Select this mode when the standard Cool mode does not
provide sufficient dehumidification. The compressor and
indoor low fan will cycle together and will operate for
longer periods of time to provide the increased rate of
dehumidification. As a result, the room temperature dif-
ferential may increase slightly.
Heat mode (heat pump only)
•
When the unit is switched on from cold start or defrosting
cycle, the indoor fan will start to operate only after the
indoor coil becomes warmer.
•
When the set temperature is achieved, the indoor fan will
stop as the indoor coil starts to cool.
Air Flow Control
•
For more effective air circulation, you can manually
adjust the air discharge grille to the left or right.
•
During cool and dry mode operation, do not direct the air
discharge louver downwards as it may cause condensate
to drip. (See Figure 21).
Hot Keep (for heat pump only)
•
With the Hot Keep switch OFF, the indoor fan will stop
when coil temperature drops to 86°F. With the switch ON,
the fan will not stop unless coil temperature drops below
65°F. With the switch in INTERVAL, and the unit is not
heating, the fan is on for 30 seconds and off for 2
min.(See Figure 21).
•
In cool mode, fan runs continuous at selected speed.
•
The switch is located on front of the indoor unit, above
the ON/OFF switch. (See Figure 21).

Overheating protection (heat pump only)
•
If the indoor coil temperature exceeds 145°F because of
high ambient conditions, dirty air filter, etc., the compres-
sor will turn off.
Frost prevention
•
If the indoor coil starts to frost in cooling mode, the com-
pressor will stop and the Power indicator light will blink.
•
If the outdoor coil becomes frosted, heating will stop for a
few minutes while the unit goes into defrost and the Heat
indicator light blinks.
Fan speed and rated cooling capacity
•
The rated cooling capacity is provided at the maximum
fan speed.
•
The cooling capacity is slightly lower when the unit is
operating at MEDIUM and LOW fan speed.
Main Filters - Permanent and Washable
Air filters must be cleaned at regular intervals. Twice annu-
ally may be adequate in some areas, while twice monthly
may be required in others. Areas with high dirt and lint con-
tent or heavy usage of units require more frequent filter
maintenance than those areas of relatively clean operating or
low usage conditions. Unit malfunction will occur if air fil-
ters are not kept clean. Vacuum the filters from the dirty side
or wash with hot water and a mild detergent. Allow the filters
to dry thoroughly before replacing them. See Figure 22.
Electrostatic Air Purifying Filter
Pre-charged electrostatic polypropylene filter removes
microscopic dust, smoke and small invisible particles to keep
the room air clean.
Deodorizing Filter
Activated carbon filter removes unwanted smells and odors
in the air and keeps the room air fresh.
