3.4 OPERATION WITH CONTINUOUS DRAINAGE

On the rear of the unit, remove the rubber plug carefully. 

Remove the water tank first, then push the hose onto the connector located inside of the hole. 

The hose should go down smoothly without bends or kinks.

Place the end of the hose into a suitable drainage location for condensate removal.

3.5 MAINTENANCE

3.5.1

 

Precaution

Be sure to unplug the unit before cleaning.

Do not use harsh detergents, thinners or other chemical agents to clean the unit as this may damage the unit.

Do not wash the unit directly under a tap or hose. The electrical components inside may be damaged and the unit 

become unsafe as a result.

3.5.2 Air filter

Clean the air filter at least once every two weeks to prevent impaired performance of the unit.

Pull the air filter out and Wash the air filter with clean water, and then carefully dry (see figure below).

3.5.3 Unit enclosure

Use a soft, clean cloth to wipe the surface. Do not use water as this may cause an electrical fault or shock hazard.

3.5.4 Water tank

Wash the tank using warm water 104°F (about 40°C) with neutral detergent. Rinse and allow 

to air dry. Replace tank when dry.
