OPERATING THE UNIT

Positioning the unit
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.

Casters(At four points on the bottom of the unit)

• Casters can move freely.

• Do not force casters to move over the carpet, nor move the unit with water in the bucket. (The unit may tip over and spill water.)

• Do not use outdoors.

• This dehumidifier is intended for indoor residential applications only. This dehumidifier should not be used for commercial or industrial applications.

• Place the dehumidifier on a smooth, level floor strong enough to support the unit with a full bucket of water.

• Allow at least 20cm of air space on all sides of the unit for good air circulation (at least 40cm of air space on air outlet).

• Place the unit in an area where the temperature will not fall below 5 C(41 F). The coils can become covered with frost at temperatures below 5 C(41°F), which may reduce performance.

• Place the unit away from the clothes dryer, heater or radiator.

• Use the unit to prevent moisture damage anywhere books or valuables are stored.

• Use the dehumidifier in a basement to help prevent moisture damage.

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

• Close all doors, windows, and other outside openings to the room.

When using the unit

• When first using the dehumidifier, operate the unit continuously for 24 hours. Make sure the plastic cover on the continuous drain hose outlet install slightly properly so there are no leaks.
• This unit is designed to operate in a working environment between 5t/41 °F and 35t195 °F.
• If the unit has been switched off and needs to be switched on again quickly, allow approximately three minutes for the correct operation to resume.
• Do not connect the dehumidifier to a multiple socket outlet, which is also being used for other electrical appliances.
• Select a suitable location, making sure you have easy access to an electrical outlet.
• Plug the unit into an electrical socket-outlet with an earth connection.
• Make sure the Water bucket is correctly fitted otherwise the unit will not operate properly.
  NOTE: When the water in the bucket reaches a certain level, please be careful to move the machine to avoid it falling down.

Removing the collected water

There are three ways to remove collected water.
1. Use the bucket

• When the unit is off, if the bucket is full, the Full indicator light will light.
• When the unit is on, if the bucket is full, the compressor and the fan turn off, and the Full indicator light will light, the digital display shows P2.
• Slowly pull out the bucket. Grip the left and right handles securely, and carefully pull out straight so water does not spill. Do not put the bucket on the floor because the bottom of the bucket is uneven. Otherwise, the bucket will fall and cause the water to spill.
• Throw away the water and replace the bucket. The bucket must be in right place and securely seated for the dehumidifier to operate.
• The machine will re-start when the bucket is restored to its correct position.

NOTES:

• When you remove the bucket, do not touch any parts inside of the unit. Doing so may damage the product.
• Be sure to push the 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 hose drops when you remove the bucket (see Fig.7), you must reinstall the pump hose properly to the unit before replacing the bucket in the unit (see Fig.8).
• When you remove the bucket, if there is some water in the unit you must dry it.
• When the unit is on, if the bucket is removed, the compressor and the fan turn off, then the unit will beep 8 times and the digital display shows Eb.
• When the unit is off if the bucket is removed, the unit will beep 8 times and the digital display shows Eb.

2. Continuous draining

• Water can be automatically emptied into a floor drain by attaching the unit with a water hose (Id..-1:15/16″, not included) with a female threaded end (ID: M=1″, not included)
• Remove the plastic cover from the back drain outlet of the unit and set it aside, then insert the drain hose through the drain outlet of the unit and lead the drain hose to the floor drain or a suitable drainage facility. (See.Fig.9 and Fig.10)
• When you remove the plastic cover if there is some water in the back drain outlet of the unit you must dry it. Make sure the hose is secure so there are no leaks and the end of the hose is level or down to let the water flow smoothly.
• Direct the hose toward the drain, making sure that there are no kinks that will stop the water from flowing.
• Select the desired humidity setting and fan speed on the unit for continuous draining to start.

NOTE: When the continuous draining feature is not being used, remove the drain hose from the outlet, and dry the water in the continuous drain hose outlet.

1. Pull out the bucket a little.
2. Hold both sides of the bucke• with even strength, and pull i out from the unit.

Removing the collected water
3. Pump draining (on some models)
Water can be automatically emptied into a floor drain or a suitable drainage facility by attaching the pump drain out with a pump drain hose (4’od=114″ , supplied).

• Remove the continuous drain hose from the unit and install the plastic cover to the continuous drain hose outlet of the unit by clockwise rotation.(See Fig.11)

• Resort the pump drain hose into the pump drain hose outlet for a depth of 15mm at least (See Fig.11), then lead the water hose to the floor drain or a suitable drainage facility.

• Press the pump pad of the unit to activated the pump operation. When the bucket is full the pump starts to work.
  NOTE: The pump may cause big noise when it starts to work for 3-5 minutes. It is a normal phenomenon.

• Make sure the hose is secure so there are no leaks.

• Direct the hose toward the drain, making sure that there are no kinks that will stop the water from flowing.

• Place the end of the hose into the drain and make sure the end of the hose is level or down to let the water flow smoothly. Do never let it up.

• Select the desired humidity setting and fan speed on the unit for pump draining to start.
  NOTE: The pump operation on light blinks at 1Hz when the pump is an operational failure. Please tum off the unit and plug the power cord out. Check the following things:

• Cleaning the filter of the pump. -Remove the bucket from the unit, take down the pump and clean the filter of the pump (See Fig.12).

• Check that the pump drain hose does not link or block.

• Empty the water of the bucket.

• Reinstall the pump hose if it drops and reinstall the 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 0°C (32°F), otherwise water becomes ice that will cause the water hose to block up and the unit failure. Make sure to empty the bucket once a week when using the pump draining feature. When the pump draining feature is not being used, remove the pump drain hose from the outlet.

• Press the pump drain hose outlet in and take the pump drain hose out from it (See Fig.13). Make sure to not let the water in the pump hose drip to the floor.
