PARTS IDENTIFICATION

NOTE: DO NOT OBSTRUCT THE AIR INLET OR OUTLET.

OPERATION INSTRUACTIONS

Position Your Dehumidifier

• Install the dehumidifier horizontally to minimize vibration and or noise.
• You can adjust the feet to level the dehumidifier.

To adjust the feet

• Turn the nut in a clockwise direction to get the nut loosen;
• Turn the foot in a clockwise direction to get the foot down or turn the foot in a counterclockwise direction to get the foot up;
• Turn the nut in a counterclockwise direction to fix the foot.

NOTE

• For best results, operate your dehumidifiers in an enclosed area.
• Close all doors and windows that open to the outside to maximize water removal efficiency.
• Place your dehumidifier away from obstructions, and keep it away from anything that could block airflow into and out of the unit.

Connect the Drain Hose

• Connect the drain hose to the Gravity Drain Outlet;
• Place the unattached end of the hose to a suitable drainage facility.

Note: The drainage facility should be lower than the drain outlet of the dehumidifier.

(Ensure there are no kinks or other obstructions that will stop the water to flow.)

Picture 1: Example of improper installation.

• The water pipe is in upward arch position (point D) above point B. Inside of the water pipe is prone to air and accumulation, which leads to a low discharge through the pipe.

Picture 2: Example of improper installation.

• The water container (point D) is lower than the continuous drain pipe (point A) but higher than the point B. Inside the pipe is prone to air and water leading to a low discharge of water through the Pipe.
• Do not place pipe outlet (point C) into water.

Picture 3: Example of proper installation.

• The water pipe is positioned from high to low leading the water to smoothly flow on the continuous drainage port (point A through point C) which can be discharged into the sewers or a water container. (Note: The outlet, point C, is placed 3.97inches above point A. Extensions or adding additional pipes is not recommended.)

Plug in

IMPORTANT: Please let the dehumidifier sit outside the box for 24 hours before initial plugging in.

• Uncoil the power cord and plug it firmly into a properly grounded 110-120 volt AC outlet.
• After plugged in, the control panel will light up for 1-2 seconds and then goes off, which is the normal self-diagnose process and does not require any user intervention.

Understand the Control Panel

• The control panel on the dehumidifier has an LCD screen and 4 buttons. Press the ON/OFF Button to turn the dehumidifier on. The LCD screen will light up and display the readouts as below.

What is on the LCD Screen?

• Big Font Digital Number (43 RH% on the above illustration) is humidity percentage reading of the inlet air that the dehumidifier detects which is similar to the room humidity level. When you are pressing the ▲ or ▼ button to set a desired humidity percentage value, the big font digital number will turn to display the setting value and flash.
• Small Font Digital Number (77°F on the above illustration) is temperature reading of the inlet air which is similar to the room temperature. However, if the timer function is being set or has been activated, the small font digital number will turn to display the timer setting value or time remaining.
• Running Icon： Running icon flickers typically because the compressor has not kicked in. It usually happens ① when the dehumidifier is under the 3-minute compressor delay status; ② when the dehumidifier is programmed to delay-start (AUTO ON TIMER).
• Wet Controller Icon: Wet Controller Icon flickers when the room humidity level (inlet humidity reading) is 3% lower than the set humidity. When you see the “wet controller” icon illuminating while setting up, it typically means the set humidity level is not 3% lower than the inlet humidity reading. Please make sure the set humidity value is at least 3% (10% recommended) lower than the inlet humidity reading. In Humidistat Mode, if you see “wet controller” icon illuminating after running the dehumidifier for a while, it means the dehumidifier has got the room humidity down to the set point and the dehumidifier enters into standby mode.
• Defrosting Icon: The dehumidifier begins to defrost when the frost has accumulated on the interior of the dehumidifier. When the dehumidifier is defrosting, the fan is running, but the compressor is not, the defrost icon is flashing. The dehumidifying function will cease until the frost has melted. When defrosting is complete, the defrosting Icon will disappear and the dehumidifier begins to dehumidify again automatically.
  • Note: The frequent defrost process indicates that the room temperature is too cold. Therefore, if the room temperature is lower than 60°F, please consider adding heat to promote proper drying.
• Fan Icon: The fan icon illuminates when the fan is running.
• Water Droplets Icon: The water droplets icon illuminates when the compressor kicks in, which means the dehumidifier is dehumidifying. When the compressor delays to start due to the 3-minutes delay system, this icon flickers.
• Timer Icon: Timer icon illuminates when the timer function is enabled.

Understand the Control Buttons

• ON/OFF Button: Press to turn the dehumidifier ON or OFF.
• ▲ Button: Press ▲to increase the set-point of humidity level or timer.
• ▼ Button: Press ▼ to decrease the set-point of humidity level or timer.
• Timing/Function Button: Press once to check the settings. Press and hold for 3 Defrost seconds to enter Timer setting system.

General Operation Instructions

1. Turn the Dehumidifier On
   • Press the ON/OFF button to turn the dehumidifier on. Typically, the dehumidifier will run in the default setting with set humidity 30%.
2. Set a Desired Humidity Percentage Value
   • Press ▲ or ▼ button to set your desired humidity percentage value between 10%-98% in increment of 1 %. 40%-60% is a general humidity setting guide. After selected the target value, press Timing/Function Button to confirm your setting, or let the setting be registered automatically after 5 seconds of no operations on the control panel.

Note

The dehumidifier with a humidistat will stop and start automatically to maintain room humidity level within a range of ±3% of the set point.
For example, if the set humidity is 50%,

• when the inlet humidity level the dehumidifier detects is 47%, 3% lower than the set humidity, the dehumidifier will automatically stop and enter into “wet controller” mode.
• when the inlet humidity level the dehumidifier detects raises to 53%, 3% higher than the set humidity, it will automatically restart.
• However, if the set humidity level is equal to or lower than 30, the dehumidifier will enter CONTINUOUS MODE where the dehumidifier will run continuously.

Turn the Dehumidifier Off

• Press the ON/OFF to turn the dehumidifier off.

Note: To protect the compressor, the fan will continue to operate for 5 seconds after the dehumidifier has shut off. So please do not disconnect the power cord to force the dehumidifier to stop. Always use the power button.

Water Drainage

During normal operation, this dehumidifier will automatically drain by the force of gravity. If you want to move or store your dehumidifier, wait at least 10 minutes to allow the dehumidifier to completely defrost, then lean the dehumidifier gently towards drain to ensure that it is completely drained.

Timer Setting

The TIMER function enables you to either delay AUTO-ON or delay AUTO-OFF the dehumidifier in the choice from 1 hour to 24 hours.

• Setting an AUTO-ON timer: When the dehumidifier is off, selecting Timer will turn the dehumidifier on in the hours that will be set.
• Setting an AUTO-OFF timer: When the dehumidifier is on, selecting Timer will turn the dehumidifier off in the hours that will be set.

Follow the below steps to set the TIMER:

• Press and hold the Timing/Function Button for about 3 seconds, until you see the TIMER icon lights up and the small font digital number changes into 00 H and flashes.
• Adjust the timer setting by pressing ▲ or ▼ button repeatedly to change the delay timer at 1-hour increments, up to 24 hours.
• After selected the target timer value, press Timing/Function Button to confirm your setting, or let the setting be registered automatically after 5 seconds of no operations on the control panel.
• The small font readout will count down the time remaining (8,7,6, etc.) until the dehumidifier either starts or stops.
• To disable the timer function, manually turn ON/OFF the dehumidifier, or set the timer to 00 H.

Note

• Before entering the AUTO ON TIMER setting, make sure power is being supplied to the dehumidifier.
• For the AUTO ON setting, please turn on the dehumidifier to select a desired humidity level.
• Otherwise, the humidity maintained will be the same as the previous setting.
• You can only set AUTO ON timer when the dehumidifier is off or set AUTO OFF timer when the dehumidifier is on, but not be able to set both AUTO ON and AUTO OFF timer at the same time.
• The TIMER will ONLY function one time instead of cycling the dehumidifier on or off indefinitely.
• The TIMER function will be disabled when the dehumidifier has been powered on/off manually.
• Set the timer as 00, the timer function will not be activated.

Connect the Dehumidifier to an External Pump to Drain

Make sure your dehumidifier is turned off and unplugged before the following operations:

• Run the drain hose from the Gravity Drain Outlet down into the external pump (The drain hose nor the external pump can be above the Gravity Drain Outlet).

NOTE

• If the pump has a water full signal cable, connect it to the External Pump Terminal on the dehumidifier, then the dehumidifier will auto stop when the pump is full to avoid leakage. However, connecting a water full signal cable is not a must for using an external pump to drain.
• Not all the output signal of the external pump compatible with this dehumidifier.

If the external pump output signal compatible with our dehumidifier

When the pump is full, the dehumidifier stops working and displays E5 and the external pump starts to drain the water out. After the pump drained, the dehumidifier will automatically restart. When the dehumidifier displays an E5 error after confirming the compatibility with the pump signal, it typically because the drain hose or the water pump is blocked. Please turn off the dehumidifier and troubleshoot, and then restart the dehumidifier after troubleshooting.

If the external pump output signal NOT compatible with our dehumidifier

• After connecting the output signal cable to the dehumidifier, the dehumidifier does not work and displays an E5 error and the pump does not work, which indicates the external pump output signal is not compatible with our dehumidifier.
• In this case, please disconnect the signal cable from the dehumidifier, turn off the dehumidifier and then restart the dehumidifier. The dehumidifier will automatically eliminate the Error code and resume working.

Smart Functions

1. 3 Minutes Compressor Delay Mechanism
   • To avoid any damage to the dehumidifier, the dehumidifier will not start operation following a complete cycle until after 3 minutes. Operation will automatically start after 3 minutes. In other word, if you turn the dehumidifier off and then restart it immediately, the compressor will not kick in until 3 minutes later. During this period, you can see the RUNNING icon flashing on the LCD screen until the compressor kicks in.
2. Auto Defrost
   • When the frost builds up on the evaporator coils, the compressor will cycle off and the fan will continue to run until the frost disappears. When the dehumidifier is defrosting, you can see the DEFROSTING icon light up on the LCD screen.
3. Auto-Restart
   • If the dehumidifier shuts off unexpectedly due to power outage, the dehumidifier will restart with the previous function settings automatically when the power resumes.
4. Temperature Protection Function
   • When the room temperature is higher than 113°F, the dehumidifier will automatically enter into HIGH-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays an “HH” message and the compressor stops.
   • When the room temperature is lower than 40°F, the dehumidifier will automatically enter into LOW-TEMPERATURE PROTECTION SYSTEM where the LCD screen displays an “LL” message and the dehumidifier stops working.

Note: When you see HH or LL message under normal circumstances, please contact the customer service at service@moiswell.com to get technical support.

MAINTENANCE

To avoid possible electric shock, ensure to turn the dehumidifier off and disconnect the plug from the power source before performing any cleaning or maintenance.

Cleaning the Dehumidifier

Clean the dehumidifier housing with a soft damp cloth. Do not submerge or place water on the dehumidifier or control panel. Water may damage the electronic components of the dehumidifier. Do not use chemical solvents such as benzene, alcohol, gasoline or other heavy-duty cleaners. The surface may become damaged or deformed.

Cleaning the Air Filter

The working performance of the dehumidifier will be greatly reduced if the filter becomes blocked. The air filter should be cleaned approximately every 2 weeks and may require more frequent cleaning if there is significant dander or fur in the air. The air filter is located behind the inlet grill.

Follow the steps below to clean the filter:

• Unscrew the hand screw on the top of the inlet grill, open the inlet grill and take the filter out.
• Use a vacuum cleaner with a soft brush attachment to remove any large debris or dust build-up from the filter.
• Wash the filter in lukewarm, soapy water, below 40°C (104°F), or use a neutral cleaning agent.
• Rinse the filter with clean water and dry thoroughly.
• Re-install the filter.

NOTE: DO NOT operate the dehumidifier without a filter because dirt and lint will clog it, hence reducing performance.
