VI. Drainage Instructions
1. Manual Drainage:
• When the water tank is full and the air conditioner is off, unplug the unit.
• Move the machine carefully, so as not to spill water into the bottom of the body.
• Place the water container below the side water outlet, behind the body.
• Unscrew the drainage cover and unplug the water plug; water will begin to flow into the
water container.
• During drainage, the air conditioner body can be tilted slightly.
• If the water container cannot hold all the water, stuff the water outlet with the water plug
before the water container becomes full to prevent water from flowing onto the floor or
carpet.
• When the water is completely discharged, stuff the water plug back and tighten the drainage
cover.
• Restart the machine after the water plug and drainage cover are reinstalled, otherwise water
will leak onto the floor.
2. Continuous Drainage:
(Optional and only applicable to Cool and Dry modes)
• Unscrew the drainage cover and unplug the water plug.
• Set the drainage pipe into the water outlet.
• Connect the drainage pipe to the bucket.

hands. Force down from the outside to remove the EVA Filter screen frame. Unscrew four
screws of the EVA Filter screen and the rear housing to remove the filter screen (Fig. 7).
Put the filter screen into warm water with neutral detergent (104°F), rinse and leave to dry in
a shaded area.

Postseason Storage:
• Unscrew the drainage cover, unplug the water plug and empty the water from the water tank
into other water containers, or directly tilt the body to discharge water into a drain.
• Turn on the machine, adjust it to low speed ventilation mode and maintain this state until the
drainage pipe becomes dry. This will keep the inside of the body in a dry state and prevent
mildew.
• Turn off the machine, unplug the power plug and wrap the power cord around the wrapping
post. Then reinstall the water plug and drainage cover.
• Remove the exhaust pipe before storage.
• Cover the air conditioner with a plastic bag. Store all components in a dry place, away from
dust and out of the reach of children.
• Remove batteries of the remote control and store for later use.
