Unit operation

Protection devices inside the unit will activate to stop unit operation, when ambient

temp. is extremely low or high.

When unit is running under high humidity in cooling or dehumidifying mode, condensate

might appear at outlet grill.

3-min delay protection

Fan speed changes

Unit will not restart until 3 min have elapsed for the protection of the unit.

room temp. is approaching temp. setting.

In dry mode, fan speed will change automatically.

Operation hints

Cold draft prevention

Use objectively

efrosting

In heating mode, indoor fan will not run for the first 2 5 min. due to cold draft prevention.

When frost accumulates on heat exchanger in heating mode, unit will start defrosting

automatically.

During defrosting, both indoor and outdoor fan stop.

After defrosting, unit resumes running.

Heat pump works by means of absorbing outside heat to warm room air, so outdoor

temp. degree will affect unit's heating efficiency.

Energy saving

Keep proper room temp.

Too cold or too warm is no good

to your health, and power

consumption will be increased as

well.

Air filter should be periodically cleaned

If air filter is clogged:

It will cause poor cooling and

heating efficiency, higher power

consumption and even problem

may occur. In cooling operation,

water will flow out.

Use Timer effectively

You may use Timer mode to keep

a comfortable room temp.when

you wake up or come home from

outside.

Avoid direct sunlight

and air flow

Adjust air flow

properly

Proper temp.

There might be certain power consumption even

if unit is stopped.

Clean air filter and indoor unit, cover outdoor

unit after cleaning.

Indoor and outdoor cleaning

Trouble shooting

Followings are not problems

Sound of water flowings are not

problems.

Sound of cracking is heard.

Smells are generated.

During operation, white fog or steam

comes out of indoor unit.

In cooling operation, unit switches to fan

operation.

Unit will not restart after stop.

Won't start?

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

dry mode.

In heating operation, water or

steam are blown out of indoor

unit.

In heating operation, indoor fan won't stop even

if unit is stopped.

During unit start and 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 temperatuer changes.

This is because the system circulates smells from the

interior air such as the smell of cigarettes or the painting

on the unit.

When unit is running at places like restaurant where dense

edible oil fumeis always exist, this will happen.

To prevent frost from accumulating on indoor heat

exchanger, unit will switch to fan 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.

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 stops, indoor fan will go on running until indoor

unit cools down.
