Air-conditioner operating conditions
■
Use within the following operational range. Operating outside of this range may result in the protection devices being activated, preventing the
unit from working.
Cooling operation
Heating operation
Outside temperature Approximately 21 to 43 °C
Approximately -5 to 21 °C
Inside temperature
Approximately 21 to 32 °C
Approximately 15 to 30 °C
Below approximately 80%
The long-term use of the unit with a humidity level
Inside humidity
exceeding 80% may result in condensation forming on the
—
surface of the indoor unit, leading to water drips.
Characteristics of HEAT mode operation
Mechanism and capacity of HEAT mode operation
■
Mechanism
•
The unit draws in heat from the cold outside air, transfers it indoors and heats the room. The heating capacity of the heat pump mechanism decreases
when the outside air temperature gets colder.
•
The hot air circulation system takes a while before warming up the room temperature.
•
If the outside temperature becomes extremely low, it would be better to use an additional source of heating.
Defrosting
If the outside temperature becomes low and humidity is high, the heat exchanger in the outdoor unit may frost over, which prevents efficient heating.
If this happens, the automatic defroster is activated and during defrosting the heating operation stops for 5 to 10 minutes.
•
Both indoor and outdoor fans stop and the RUN light (green) blinks slowly (1.5 sec. ON, 0.5 sec. OFF) during defrosting.
•
The outdoor unit may give off some steam during defrosting. This is to help the defrosting process and is not a defect.
•
The HEAT operation resumes as soon as defrosting has been completed.
Press the FAN SPEED button
Set the fan speed as desired.
