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 the 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 the appliance will not turn on.
- Do not cover the air intake and outlet.
- Do not place the appliance in front of curtains or drapes – to ensure they do not obstruct the air intake.
- Keep curtains, blinds or drapes closed during the sunniest part of the day.
- Close all windows and doors.
- Indoor relative humidity should ideally be kept between 35%RH and 60%RH depending on the ambient temperature.
- Make sure the appliance is on a hard and level surface.
- To prolong the compressor’s life, please wait at least 3 minutes before turning the appliance back on after shutting it off.
- Inspect and keep the air filter clean by cleaning regularly.
- Perform routine maintenance.

Energy Saver
When the unit is running on normal operation, once the RH% is reached, the fan
will still run continuously to avoid high start-up amperage which makes the
unit energy-efficient. Please note that the fan may run continuously or shut
off intermittently depending on the RH% and set humidity.
PARTS AND CONTROLS
Bucket Full Indicator
The appliance will run continuously until the set RH% is reached or when the
drain bucket is full. When the drain bucket is full, the Full indicator light
will illuminate and the dehumidifier will stop operating. Remove the water in
the bucket with two hands, then place the drain bucket back to it’s proper
position and the machine will start operating
again.
Auto Defrost Indicator
In the event frost builds up on the evaporator coils, the compressor will
cycle off and the fan will continue to run until the frost is evaporated. This
happens when the appliance is operating in low temperatures (less than 53°F or
12°C), which affects the efficiency of the dehumidifier. When this happens,
the Auto Defrost light will turn on and the machine will go into periodic
defrost mode automatically.
Defrost time may vary. If the dehumidifier freezes up, turn the appliance off
for a few hours and then restart. The appliance will not operate
satisfactorily if the room temperature is below 41°F

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:
-
DRAIN BUCKET METHOD
1. When the bucket 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.3 and Fig. 4.
4. Remove the water from the drain bucket and replace it back to the dehumidifier. The drain bucket must be installed properly and securely 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. -
CONTINUOUS / GRAVITY DRAIN METHOD
Water can be automatically emptied into a floor drain by attaching a standard 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. Remove the continuous drain cover and then attach a continuous/gravity
drain hose. Make sure the hose is securely fastened to prevent leakage.|
