Heating Performance

Microcomputer-controlled Automatic Defrosting

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.

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).

Clean the air filter

Pull the filters upward to remove them from the Intake Grill.

Clean the air filter: Remove the dust from the filters by vacuum cleaner or washing

them. After washing, allow the air filters to dry thoroughly in an area protected from

sunlight.

Re-attach the air filters to the Intake Grill. Press the two buttons on the filters until

you hear a sound of click.

Maintenance

When used for extended periods, the unit may accumulate dirt inside, which reduces its performance. We recommend

that the unit is inspected regularly, in addition to your own cleaning and care. For more information, consult authorized

service personnel.

When cleaning the unit's body, do not use water hotter than 40 C, harsh abrasive cleansers, or volatile agents like

benzene or thinner.

Do not expose the unit body to liquid insecticides or hairsprays.

When shutting down the unit for one month or more, first allow the Fan mode to operate continuously for about half a

day to allow internal parts to dry thoroughly.
