8 Opertion tips
Kelvinator Air Conditioning
Operation tips
Cooling Operation
Principle
Air conditioners absorb heat from the room and transmit it to
the outdoor unit, so that the room temperature is decreased.
The cooling capacity will increase or decrease according to
the outdoor ambient temperature.
Antifreezing Function
If the unit is operating in COOL mode and in low ambient
temperature, frost may be formed on the heat exchanger.
When indoor heat exchanger temperature decreases below
zero, compressor will stop operation to protect the unit.
Heating Operation
Principle
Air conditioners absorb heat from outdoors and transmit it
to the indoor unit, increasing the indoor room temperature.
The heating capacity will decrease at low ambient temperature.
Defrosting
When outdoor temperature is low but humidity is high, ice
may form on the outdoor unit during extended operation,
affecting the heating efficiency. The air conditioner may
stop operation during an auto defrosting operation to
remove this ice. During auto defrosting, the fan motors of
indoor unit and outdoor unit will stop. During defrosting,
the indoor indicator flashes “H1” and the outdoor unit may
emit water vapor. This is not a malfunction. After defrosting
is finished, the heating operation will recover automatically.
Anti-cold Air Function
In HEAT mode, the indoor fan will not operate in order to
prevent cold air being blown into the room (within 2 minutes).
If the indoor heat exchanger doesn't reach a minimum
temperature under the following three states:
1 Heating operation starts;
2 After Auto Defrosting is finished;
3 Heating at low temperature.

Tips for energy saving
• Do not overcool or overheat.
Setting temperature at a moderate level helps
energy saving.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors is favourable
for cooling (heating).
• Clean air filters once a month.
Clogged air filters lead to inefficient operation and
energy waste.
Tip for relative humidity
Condensate water is likely to form at the air outlet if cooling
or drying for a long time when the relative humidity is more
than 80% (with doors and windows open).
