Draining the Unit
When the portable air conditioner is in cooling mode, dehumidify mode, or heat mode on certain models, it
will remove moisture from the air. The condensed water from the air will be collected in an internal
reservoir and will be evaporated and exhausted out of the exhaust hose. However, in very humid conditions,
the internal reservoir may fill completely. This causes the air conditioner to turn off to avoid overflowing the
internal reservoir. The WATER indicator will light up on the Control Panel.
Direct Drainage
1. Remove the rubber drain plug from the drain port.
2. Connect a drain hose to the drain port.
The portable air conditioner will now drain through the drain hose.
DRAINAGE OPTIONS
Your Koldfront portable air conditioner comes with several different options for draining the water
accumulated during operation. The most common will be the self-evaporative mode. The unit will do this
automatically. This mode will be sufficient for most environments. If you are operating the unit in an
environment with higher levels of humidity you may choose one of the other drainage options to help
remove the excess water.
Continuous Drain
This unit has the capacity for continuous drainage. It includes an internal pump to help remove water.
This means the unit will push the water to the drain instead of relying on gravity to bring the water to
the drain. If there is an obstacle in between the unit and the drain, the pump will push the water over
that obstacle and through the water line. In order to run the continuous drain function you will need to
do the following:
1. Connect the included water line to the unit. You will need to attach the quick connect adapter on the
end of the water line to the back of the unit.
2. Place the other end of the water line (drainage end) into a drain. The unit will recognize that the
quick adapter is attached and will automatically engage the water pump. The pump will turn on once
the water reservoir becomes full.
