During periods of normal use, the Air Filters should be cleaned every two weeks.

Operation Tips

Operation and Performance

*Heating Performance

This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.

Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

Instructions relating to heating (*) are applicable only to "HEAT & COOL TYPE".

*Microcomputer-controlled Automatic Defrosting

When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.

In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for about 7 to 15 minutes).

Trouble Shooting

Followings are not problems

Sound of water flowing is not a problem.

Sound of cracking is heard.

Smell are generated.

During operation, white fog or steam comes out from the indoor unit.

In cooling operation, unit switches to blowing operation.

Unit will not restart after stop.

Won't start?

During unit operation or at stop, a swishing or gurgling noise may be heard. This noise is generated by refrigerant flowing in the system.

During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperature changes.

This is because the system circulates smells from the interior air such as the smell of cigarettes or the painting on the furniture.

When unit is running at places like restaurant, etc. where dense edible oil fumes always exist, this will happen.

To prevent frost from accumulating on indoor heat exchanger, unit will switch to blowing operation for a while then resume cooling operation.

Though ON/OFF button is set to ON, unit won't resume cooling, dry or heating operation in 3 min after it is stopped, this is because of 3-min-delay protection circuit.

Please wait 3 minutes

No outlet air or fan speed can't be changed in dry mode.

In heating operation, water or steam are blown out of outdoor unit.

In heating operation, indoor fan won't stop even if unit is stopped.

Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry operation.

This occurs when frost accumulated on the outdoor unit is removed. (during defrosting operation)

After unit stop, indoor fan will go on running until indoor unit cools down.
