OPTIONAL PARTS

13-1. REFRIGERANT PIPES

The air conditioner has flared connections its indoor and outdoor sides.
Please use the optional extension pipe as follows.

13-2. AIR CLEANING FILTER

●

AIR CLEANING FILTER removes fine dust of 0.01 micron from air by means of static electricity.

●

Normal life of AIR CLEANING FILTER is 4 months. However, when it becomes dirty, replace it as soon as possible.

●

Clogged AIR CLEANING FILTER may reduce the air conditioner capacity or cause frost on the air outlet.

●

DO NOT reuse AIR CLEANING FILTER even if it is washed.

●

DO NOT remove or attach AIR CLEANING FILTER during unit operation.

13-3. DEODORIZING FILTER

●

DEODORIZING FILTER removes ammonia and hydrogen sulphide emitted from tobacco, and odor of pets.

●

Clean DEODORIZING FILTER every two weeks. If the filter is particularly dirty, clean the filter more often.

●

For cleaning, soak the filter in warm water for a while, and then wash and rinse it. Dry the filter in the shade
thoroughly.

●

When the filter color is still dark even after cleaning, replace the filter with a new one.
Replace the filter at least once a year.

●

DEODORIZING FILTER and AIR CLEANING FILTER can be attached on either side.
