Whynter RPD-501WP Energy Star 50 Pint Portable Dehumidifier

INTRODUCTION

How it Works

When the dehumidifier is started, the fan begins to pull moisture-laden air across the dehumidifying coils. The coils condense or draw moisture from the air, and air flows through the top louver into the room as dry, warm air. Moisture removed from air is collected in a drain bucket on the front of the dehumidifier.

The appliance is designed to operate between 41°F (5°C), and 96°F (35°C). The "Compressor" circuit has an automatic 3 minute time delayed start if the appliance is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Make sure the drain bucket is fitted correctly otherwise appliance will not turn on.

WATER DRAINAGE INSTRUCTIONS

Using a portable dehumidifier requires that collected water be emptied frequently. Draining water from this unit can be done in 3 different methods:

1. DRAIN BUCKET METHOD

1. The drain bucket can hold up to 14 pints of water. When the buck- et is full, the Full indicator light will light. The compressor and fan will turn off, the Full indicator will light, and a P2 code will be displayed.

2. It is recommended to turn the unit off before removing the drain bucket.

3. Grip the left and right handles of the drain bucket securely and carefully pull out the drain bucket. Do not put the drain bucket on the floor because the bottom of the bucket is not even which may cause the water to spill. See Fig.5 and Fig.6.

4. Remove the water from the drain bucket and replace it back to the dehumidifier. The drain bucket must be installed properly and se- curely seated for the dehumidifier to operate.

5. The machine will restart when the drain bucket is restored in its correct position. If the unit was turned off prior to the removal of the drain bucket, press the Power button to restore operation.

NOTES:

• Be sure to push the drain bucket gently all the way into the unit. Banging the bucket against anything or failing to push it in securely may cause the unit not to operate.
• If the pump filter drops when you remove the bucket (see Fig.7), you must reinstall the pump filter properly to the unit before replacing the drain bucket into the unit (see Fig.8).
• Upon replacing the bucket, firmly push the bucket in place until it locks. There should be no gaps between the bucket and the dehumidifier.
• When the drain bucket is removed, the unit will beep 8 times and the digital display shows Eb. Eb is an error code that indicates that the drain bucket is removed or not positioned correctly. Make sure that the drain bucket is properly installed and the in right position.

2. CONTINUOUS / GRAVITY DRAIN METHOD

Water can be automatically emptied into a floor drain by attaching the 20” continuous/gravity drain hose to the continuous/gravity drain outlet. To use gravity to drain your portable dehumidifier, it must be installed on a level surface or at least 12 inches above the ground, on a sturdy table or shelf unit. When using the function of continuous/gravity drainage, your drain hose must be placed horizontally below the drainage hole. Avoid uneven ground and folding the hose.

1. Install the continuous/gravity drain hose (short hose) onto the continuous hose adapter (See Fig.9) .

2. Remove the rubber drain cover from the continuous/gravity drain outlet at the back of the unit.

3. Remove the drain bucket.

4. Insert the continuous/gravity drain hose assembly through the continuous/gravity drain outlet (See Fig.10).

5. From the front of the unit and with the drain bucket removed, make sure the continuous/gravity drain hose is securely inserted to the internal connector (See Fig.11).

6. Install the two screws provided to the continuous/gravity drain hose adapter from the back of the unit.

7. Attach the 20” continuous/gravity drain hose. Make sure the hose is securely fastened to prevent leakage (See Fig.12).

8. Direct the drain hose toward a drain or other suitable drainage outlet. Make sure that there are no distortions with the hose that may stop the water flow.

9. Place the drain bucket back into the unit and make sure that it is installed correctly.

10. Select the desired humidity setting and fan speed on the unit for continuous draining to start.

3. WATER PUMP METHOD

One of the key features of this dehumidifier is that it has a water pump that pushes water up or over a longer distance. Using this feature will enable your unit to run maintenance free.

NOTE: The water pump will ONLY engage when the drain bucket is full.

1. Make sure the continuous/gravity drain assembly is removed from the continuous/gravity drain outlet and the plastic cover is installed.

2. Insert the 16 ft. pump drain hose (included) into the bottom pump drain outlet (See Fig.14), then lead the drain hose to a suitable drainage facility. Make sure that the hose is fully inserted to avoid water leakage and no kinks which will cause the water to stop flowing.

3. Press the Pump button to activate the pump operation.

NOTE: The water pump will ONLY engage when the drain bucket is full.

4. The water pump may make some noise when it starts to work within the first 3 - 5 minutes. This is a part of the unit’s normal operation.

5. Select the desired humidity setting and fan speed on the unit.

NOTE: The Pump Indicator Light will flash when there is a failure in the pump operation. Please turn off the unit and unplug the power cord and check the following points:

Clean the pump filter - remove the drain bucket from the unit, pull down the pump filter, and clean (See Fig.15).

Check the pump drain hose for kinks or obstructions Reinstall the pump filter and drain bucket properly. Turn on the unit. If the error repeats, call for service.

NOTE: Do not use this operation when the outdoor temperature is equal to or less than 32°F. Otherwise, water hose may be blocked as the water will turn to ice and cause the unit to fail. When the pump drain feature is not being used, remove the pump drain hose from the outlet.
