2. Pinch the handle under the air filter and make the air filter arched, remove it from the slot from the underside to the upside(Model A). Grasp the handle of the filter, then slide it downwards to remove the filter(Model B).
3. Clean the filter with warm, soapy water. The water should be below 40°C (104°F) to prevent distortion of the filter.4. If your filter has a small air freshening filter, clean this air freshening filter with a hand-held vacuum.
4. Rinse the air filter with fresh water, then shake off excess water.
5. Dry it in a cool, dry place, and refrain from exposing it to direct sunlight.

If your filter has a small air freshening filter(optional), it can be installed at any of the four positions, install it at the position you like. Clean it with a hand-held vacuum.

CAUTION
NEVER operate the air conditioner without the air filter, as dust/dirt particles can contribute to equipment failure.

Winter Storage
If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.

WATER DRAINAGE

The condensed water can be treated as follows: Bottom drainage (Applicable for the units designed with a bottom drain hole only. )
– Remove the rubber plug from the bottom of the cabinet(if any)
– Take out the drain pan and screws from the accessory.
– Fix the drain pan onto the bottom of the cabinet with screws.
– Connect an extension drain hose (locally purchased) to the outlet of the drain tray.
NOTE: The bottom drainage will slightly affect cooling performance, but it can reduce the noise caused by spraying the condensed water. For pump heating, the bottom drainage must be chosen.

Back drainage

– Fit the seal onto the drain joint(provided as an accessory).
– Insert the drain joint into the back drainage hole, and rotate it by 90° to be well fitted.
– Connect an extension drain hose (locally purchased according to the installation length request) to the drain joint.
