7. Auto Restart
   Auto Restart will turn the unit on automatically when the power returns

8. Auto-Defrost Sensor(Built-in)
   When the temperature gets down to 60 F or lower, ice may form on the evaporator coils preventing the removal of moisture. The IC stops the compressor when this happens but allows the tank to continue running. When the ice is no longer present it starts the compressor.

9. Current Temp/Timer set Display
   When the machine is running, it displays the current temperature. Press the”Timer” button to set the machine to shut off or turn on automatically after a specified amount of time, it will be the collagraph

    • Setting humidity range: 40%RH~70%RH
    • Display humidity range: (LO)30%RH~(HI)90%RH

Humidity Control
When starting the dehumidifier, turn the knob to the right until the unit turns on. Adjust the knob to the desired level of dryness – turn the control knob clockwise for more drying. In the MAX position, the unit will run longer and extract more moisture from the air.

Red Indicator Light
(BUCKET FULL indicator)

When light comes on, automatic flow control turns the unit off. Turn the humidity control off before emptying the bucket.

Fan Speed

• High speed for higher moisture removal.
• Low speed for quieter operation.

Auto Frost Sensor
(Built-in)

When the temperature gets down to 60°F or lower, ice may form on the evaporator coils preventing the removal of moisture. The FROST CONTROL stops the compressor when this happens but allows the fan to continue running. When the ice is no longer present it starts the compressor.

Features/Care & Cleaning

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.

There are 2 ways to remove collected water.

1. Using the bucket
   When the bucket is full, the red indicator light, “BUCKET FULL,” will go on. You must turn the humidity control off before removing the bucket. Wait a few minutes to allow the water to stop dripping. Use both side handles to lift and remove the bucket. Pour water through the opening and replace the bucket. (See Fig. 1)
   Note: All models are equipped with built-in water overflow control. The unit will shut down when the water level reaches a maximum level in the bucket. This prevents the bucket from overflowing. The maximum water level can be adjusted by lifting the red plunger located on the top of the bucket.
   Turning the plunger clockwise about two turns will raise the water level. Turning it anti-clockwise will lower the maximum water level.

   • Warning:
     Make sure the drain cap be tightened before running the unit.

2. Use continuous drainage:
   The water can be drained out continuously through a long hose that connects to the bottom of the bucket.

   • Remove the bucket and remove the plastic cap on the bottom of the bucket.
     Then take the rubber insert out of the cap (Keep the rubber insert well for use later).
     See Fig.#1

   • Using the supplied hose, Thread the hose through the cap opening and add the washer to the cap.\ Screw the cap to the threaded mating connector on the bucket. Make sure to use the washer or the connection may leak.
     See Fig#2.

   • Thread the hose through the round hole and extend the hose to the back of the unit.
     See Fig#3

Place the bucket in its original position.

Proper use and care

• Place the dehumidifier in a location that does not restrict airflow into the rear coil or out the front grille.
• The dehumidifier must be operated in an enclosed area to be most effective. Close all doors, windows and other outside openings to the room.
• A dehumidifier operating 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.
• When you use the new model the first time, if the “BUCKET FULL” light highlights, then you can take the bucket out and put it in again, the light will die.
• Turn the dehumidifier off and remove the plug from the wall outlet before cleaning. Use water and a mild detergent to clean the inlet and outlet grilles. Do not use bleach or abrasives. The air filter is on the front of the dehumidifier. It should be checked and cleaned at least every 2 to 3 weeks or when needed.
  • To remove the filter: Unplug the unit, remove the bucket and lift out the filter. Clean the filter with a vacuum cleaner or wash it with clean water and dry it with a dry cloth.

TROUBLESHOOTING

If your Dehumidifier does not work as expected

• Before calling read the following section first.
• It will help you solve the most common problems that might occur and which can be easily corrected.
• If all efforts fail and you need service, a toll-free number is available please use it to contact our customer service.

Items to check before calling for service:

Unit not operating

• Make sure the plug is pushed completely into the outlet.
• The fuse is blown or the circuit is tripped. Check the house fuse/circuit breaker. Replace the fuse or reset the circuit breaker.
• The bucket is full. The dehumidifier automatically turns off when this occurs. The drain bucket needs to be emptied.
• When the ambient temperature is above 122F or below 32F, the model will restart after shutting off for 3 minutes to protect the compressor.

The dehumidifier is icing up during the initial stage of operation

• This is normal. Frost will usually disappear within 60 minutes unless the temperature is below 60°F. This is normal for the dehumidifier.

Airflow is restricted

• Make sure there are no curtains, blinds or furniture blocking the front or back of the dehumidifier.
• Additional note: After prolonged usage, the condenser coils behind the filter may develop a buildup of residual. Unless cleaned regularly with a soft brush, this residual will harden through time and may require special cleaning methods by a refrigeration/air-conditioning serviceman.

Unsatisfactory dehumidification
When first installed, allow at least 3 or 4 days to remove the moisture from the room to maintain the desired dryness.

• The area to be humidified is too large. Check with the dealer that the model is suitable for room size and moisture level.
• The controls may not be set correctly. Adjust controls according to instructions.
• Doors and windows may not be closed. Check that all doors, windows and other openings are closed tightly and not open.
• The clothes dryer may be in operation in the same room. Install the dehumidifier away from the moisture-laden air generated by the dryer. The dryer should be vented to the outside.
• The room temperature is too low. The unit will not operate satisfactorily if the room temperature is below 60°F.
