Features
Electric Heater
Electric heaters are used in cold regions when instant heating is
required in the room.
In such cases, electric heater is preferred over heat pump models which
sometimes require long times to achieve the desired heating effect.
Coil Heater (208-230V,265 V) has different heater capacity according to
models.
Type/Capacity 2kW / 3kW / 5kW

Defrost Control
When the unit starts operating in the heating mode outdoor unit start freezing, to protect from freezing, Defrost Control is
used. Defrost operation take place when pipe temperature reaches
0℃(32℉). Defrost condition operates minimum 3minutes and maximum 9minutes for complete one cycle.
Air Ventilation
Air ventilation is carried out by means of a ventilation lever from time
to time to induct outdoor air into the room. For the air conditioner to
maintain the best cooling conditions, the lever must be in the
closed position. And when the ventilation lever is set in the open
position, the damper opens and the room air is exhausted while
at the same time fresh air from outside enters the room.
Air flow during vent door open condition for different capacity
as follows.

Energy saving Gold Fin
Heat exchangers are coated with anti-corrosive and Hydrophilic layers. It prevents the corrosion of heat exchanger.
Fins remain new for a long time and the efficiency of the heat exchanger remains constant thereby saving power and
maintenance cost.
