Humidity Control; For Maximum Dehumidification; To Remove Collected Water - Haier AHD25 Use & Care Manual

Humidity Control

A Humidity Control, built into your dehumidifier,
automatically maintains a selected humidity level. It
starts the dehumidifier when the humidity is high and
shuts it off when the humidity is low.

For maximum dehumidification

The Humidity Control has settings from "1" to " 10."
Turning the control knob to " 10" provides the greatest
amount of dehumidification, turning it to "1" provides
the least.
Even when the Humidity Control is set at " 10," the
dehumidifier will run continuously during particularly
humid periods due to seepage of humid air into the
room through the walls, around doors and windows and
through the use of clothes dryers and similar equipment
that add moisture to the air. The continuous operation
of the dehumidifier during such humid periods is
normal and necessary to maintain desired conditions.
The first 3 or 4 days that you have your
dehumidifier, run it at "10" to allow it to remove
large amounts of accumulated moisture from the
room. When the room has reached the desired
humidity level, the amount of moisture removed from
the air will be considerably less. Rotate the Humidity
Control knob toward "1" until the dehumidifier shuts
off. The Humidity Control will automatically
maintain the desired dryness in the room.

To remove collected water

Your dehumidifier has a plastic bucket that catches
the water that is removed from the air, an automatic
water overflow control, and a signal light that glows
when the bucket is full.
Before removing the bucket to empty it, turn the
Humidity Control knob to "OFF." This will prevent
the dehumidifier from operating when the bucket is
not in place.
On some models, after emptying the bucket, push it
all the way back into place and on other models hang
it on the bucket supports on each side.
(continued)
When the dehumidifier is first turned on and the
dehumidifying coil is dry, a light coating of frost will
appear. This is normal. The frost will usually disappear
in 30 to 45 minutes.
If room temperature goes below 65°F., frost may
accumulate on the dehumidifying coil, reducing the
unit's operating efficiency. The Auto Defrost control
will shut the compressor off automatically until the
coil reaches the correct operating temperature. The
fan will continue to run to aid in the defrosting.
The Auto Defrost feature is also designed to prevent
excessive on-off cycling, and under certain conditions
may allow the frost to remain on the coil for some time
before the compressor shuts off and the frost is
cleared. This is not unusual.
After replacing the bucket, be sure to turn the
Humidity Control knob back to the desired setting.
For continuous drain-off of water, attach a standard
garden hose (not supplied). A male thread is provided
on the drain or water bucket.
