Figure 2

Auto Shut-Off

This light glows when the bucket is full, or when the bucket is removed or not placed in the proper position. In these cases the Water Level Control Switch shuts off the dehumidifier.

When the light glows, check the bucket condition.

Humidity Control

When you first use the dehumidifier, turn the humidity control to 5 or 6. If you still have moisture, turn the humidity control to a higher setting.

MAX is the highest setting.

When excess moisture and dampness odors are gone, adjust the control to a lower setting. Use the dehumidifier as long as excess moisture is present.

Fan Speed

The fan control adjusts the fan speed.

Set the fan control to HIGH for maximum moisture removal. When the humidity has been reduced and quiet operation is preferred, set the fan control to

LOW.

Fan Speed

This controls the speed of the airflow.

High: Fan speed is set to high.

Low: Fan speed is set to low.

When Fan Speed button is pressed, the fan speed mode is changed.

Timer

Press this button to select type of operation.

Select continuous On for uninterrupted operation.

Select either 2 or 4 hr. On/Off for cycled operation: The unit will operate for 2 or 4 hours, and then shut off completely for 2 or 4 hours.

The cycle repeats until you change the setting.

When Timer button is pressed, the Timer indicator lights shift as follow from 2hr.On/Off to 4hr.On/Off.

Bucket Full Indicator

This light glows when the water bucket is full and needs to be emptied.

Power

Operation starts when this button is pressed and stops when the button is pressed again.

Auto Restart

Once power is restored after a power outage, the unit returns to its previous operation setting after a 2 minute delay.

The fan runs immediately when the power is restored.

Humidity Control

• This button controls the humidity in the room.

• Press

button to raise the humidity setting.

• Press

button to lower the humidity setting.

The humidity setting can be set to a permanent "On" setting or to a specific humidity setting between 35% and 70% in 5% increments.

"On" setting: Dehumidifier runs continuously regardless of humidity condition.

35% - 70% setting: Dehumidifier runs on and off according to surrounding humidity conditions.

1.6HOW TO OPERATE DEHUMIDIFIER

1.6.1HOW DOES THE DEHUMIDIFIER WORK?

Moist, humid air is drawn over a cold refrigerated dehumidifying coil. Moisture in the air condenses on this coil and drains into a bucket (or through the bucket into a hose and drain).

Dry, clean air is drawn over the condenser where it is actually heated several degrees and discharged out the rear grill into the room. (See Figure 4)

It is normal for the surrounding air to become slightly warmer as the dehumidifier operates.

This warming effect further reduces the relative humidity of the surrounding air.

1.6.2 LOCATION FOR THE DEHUMIDIFIER

Allow at least 12 inches of space on all sides of the unit for good air circulation. (See Figure 5)

The dehumidifier must be operated in an enclosed area to be most effective.

Close all doors, windows and other outside

openings to the room.

Place the dehumidifier in a location that does not restrict air flow into the front grille or out the rear grille.

The operation of dehumidifier in a basement will have little or no effect in drying an adjacent enclosed storage area, such as a closet, unless there is adequate circulation of air in and out of the area.

1.6.3 MICRO SWITCH

The micro switch assembly, which is located on the drain pan of inside unit, automatically shuts off the dehumidifier when the bucket is full (note, the Auto Shut Off lights, to indicate bucket must be emptied). The bucket replaces in its place, the unit again turns itself on.

1.6.4 AUTO DEFROST

When frost builds up on the cooling coils, the unit will automatically cycle off until the frost disappears. The fan continues to run.

NOTE: The unit will not operate satisfactorily if the room temperature is below 65˚F(18˚C). If the dehumidifier is operated in low temperature conditions frost can form in the evaporator coil and the unit will cycle ON/OFF repeatedly. In this case, please check your room temperature conditions and stop the unit.

NOTE: The low temperature operation feature in the DH504EL, DH50EL and DH65EL models will continuously cycle up to a temperature of 42°F(6°C).

1.6.5 HUMIDITY CONTROLLER

1.6.5.1 Mechanical Type

The humidity control can be set anywhere between Off and Max for normal operation.

If you need more dehumidification, turn the Humidity Control toward Max. If you need less dehumidification, turn the Humidity Control toward Off.

The relative humidity range is from 20% to 80%. (See Figure 6)

Turn the Humidity Control to Off to stop the unit manually.

1.6.5.2 Electronic Type

The humidity control can be set 'on' or 35%-70%RH(Relative Humidity) for normal operation. (See Figure 7)

If you need drier air, press theHumidity Control button.

If you need moister air, press theHumidity Control button.

Press the Power button to stop the unit manually.
