switch system. Proper installation of the water tank is crucial to maintaining reliable

 

dehumidifier operation.

 

The water tank holds accumulated condensed water and by means of a safety switch, controls both the water level and operation of the dehumidification process- i.e. When the water tank is full and/or accidentally displaced inside the cabinet, the float switch actuator (inside the tank) breaks contact with the safety switch. This condition results in the immediate shut down of the compressor and fan motor system, preventing moisture from being condensed.

DEHUMIDIFYING is a means of removing moisture from the air. A dehumidifier will help to protect your home and valued possessions from damage (swelling) caused by moisture in the air. Essentially a dehumidifier removes moisture from air as moist air passes over a dehumidifying (evaporator) coil. Moisture is condensed on the evaporator coil, drained, and collected inside an internal (removable) water tank located at the front of the unit. The exhausted air being returned into the room environment is elevated several degrees causing the surrounding air temperature to increase (slightly). This process also contributes to lowering the relative humidity of the surrounding air.

DEHUMIDIFYING

When the unit is first connected to the electrical outlet, the (green) power light

MODE INSTRUCTIONS

will not light until the “on/off” button is pressed.

When the “on/off” button is activated (pressed), the power light turns to a state “on” condition and the dehumidifier automatically defaults to:

Display: Current Ambient Room Humidity (RH%)

Humidity Setting:60% RH Fan Speed: High

IMPORTANT NOTE: Depending on humidity conditions of the surrounding environment, the dehumidifier may not start automatically under the default setting (this is an indication that the humidity level of the surrounding environment is lower than the “default” setting of 60% RH). Therefore, it may be necessary to scroll through each of the different dehumidifier settings 35% - 80% until the “humidstat” (sensor) recognizes conditions that will allow the unit to operate.

DEHUMIDIFYING MODE SELECTION:

1)To turn the unit on press the ON/OFF button.

2a) Press the humidity “UP” or “DOWN” button to select a desired RH operating value (35% -80%)

OR

2b) Press the CONTINUOUS button. When CONTINUOUS mode is selected, the humidistat (sensor) will be by-passed and the compressor will operate non-stop regardless of humidity conditions.

FAN SPEED SELECTION:

3)Select a fan speed on the keypad. The speed you select is identified by the (illuminated) indicator light located directly above the selection made.

 

Your dehumidifer features a removable Air Filter, located at the front of the unit (behind the

AIR FILTER

 

air intake grill) directly above the water tank compartment.

The air filter plays an important role in helping to reduce (minimize) dust/dirt particles from the surrounding environment. A blocked/clogged air filter reduces air intake, impacting negatively on operating efficiency.

To maintain maximum operating efficiency:

•The filter must be checked and cleaned regularly (every 2 weeks)

•More frequent cleaning may be required depending upon indoor air quality. IMPORTANT: Never operate the unit without the air filter in place.

AIR FILTER REMOVAL:

1)Grasp the filter handle, and pull the filter out. The filter will slide out easily (see Fig. 2)

2)Clean the filter thoroughly using a vacuum cleaner or wash using lukewarm water and mild detergent. Dry thoroughly before re-installing.

3)To re-install the air filter, slide the filter back inside the tracks and push inward.
