Drainage Instructions
Draining the unit manually:
Note:
Please move the AC carefully, do not spill the
water in the water pan at the bottom of the unit.
1. When the machine stops after the water is full, turn
off the machine power and unplug the power plug.
2. Place a water container larger than the sump
capacity (at least 1-1/2 quart) below the lower rear
water outlet on the back side of unit.
3. Unscrew the drainage cover and unplug the water
plug, the water will automatically flow into the water
container.
Note
: During drainage, the body can be tilted slightly
backwards. If the water container cannot hold all the
water, before the water container is full, replace the water
plug as soon as possible to prevent water from flowing on
to the floor or the carpet.
4. When the water is discharged, secure the water
plug, and tighten the drainage cover.
Note
: Restart the AC after the water plug is installed,
otherwise condensate water from the AC will drain onto
the floor or carpet.
Continuous drainage (optional, and only in dry mode)
1. Remove the upper drain plug.
2. Connect a drain hose with an outside diameter of
1/2” to the water outlet.
3. Route drain hose to a bucket or floor drain.
4. Be sure to use a large container (3 gallons or larger
is recommended) and monitor the water level in the
container continuously. The unit will not shut off when
the container is full. An overflowing container can
cause flooding and damage to the floor.
