WORKING PRINCIPLE
The Dehumidier utilizes its integral humidistat to monitor the conditioned space. When the
relative humidity goes above the selected set point, the dehumidier will energize. Air is drawn
across an evaporator coil, which is cooler than the dew point of air. This means moisture will
condense out of the air. The air is then reheated through the condenser coil and distributed
back into the room.
INSTALLATION REQUIREMENTS
1. The workspace should be enclosed.
2. Ensure at least a 6-inch clearance for intake and exhaust vents.
3. Position centrally for optimal eciency.
4. Operate only in an upright, level position.

How to Set the Humidity Level
Turn on the machine, then press the “SET” button. The humidity display will ash, showing
the current set humidity level.
Adjust the Humidity
While the display is ashing (within 3 seconds), press the “SET” button repeatedly to
change the setting:
• Humidity range: CO → 35% to 90% → CO (1% steps)
• Moisture content: CO → 25% to 200% → CO (5% steps)
• Tip:
Hold the button to scroll faster.
Once you reach the desired setting, release the button. After 3 seconds, the display will
stop ashing and show the current room humidity.
When the target humidity is reached, the machine will enter standby mode and the power
light will ash. If humidity rises again, the unit will automatically resume operation based
on the set level.
Enabling Continuous Dehumidication Mode
To set the unit to Continuous Dehumidication Mode, start by turning the machine on.
Press either the “SET” button, and the display will begin to blink, indicating that the
humidity setting can be adjusted. Within three seconds, keep pressing the “SET” button
until the display shows “CO.” This stands for continuous operation mode.
If no further buttons are pressed, the display will stop blinking after three seconds and will
show the current humidity level. At this point, the continuous mode light will turn on. In this
setting, the dehumidier will run nonstop, regardless of any changes in room humidity.
Power-o memory function
When the machine unexpectedly loses power during operation and is then reconnected
to power, it will automatically resume operation in the same mode and state as before
the power loss. However, due to a three-minute compressor protection function, the
compressor will not start running until three minutes have passed. There will be a brief
switch (approximately 3 seconds) between the fan’s on and o states, which is normal.
Please note:
Any settings made before power loss must be successfully set in order to be
remembered; otherwise, the memory function will not be activated.
The settings that are stored in memory include:
• Set humidity
• Continuous mode
• GPP function
• Water pump function (on or o)
• Temperature unit switch
Note:
The timer function and defrosting settings are not stored in memory.

GPP Function (Grains Per Pound)
By default, the unit starts in humidity mode, displaying RH% on the screen.
To switch to GPP mode, press the GPP button. The display will change to show gr/lb, and
the GPP indicator will light up. This mode displays the current moisture content. Press the
GPP button again to return to humidity display mode. While in GPP mode, the machine
operates based on the set moisture content value.
Defrost Function
This unit features an automatic defrost function.
When the ambient temperature is too low and frost builds up on internal components, the
system will enter defrost mode.
During this process, the defrost indicator light stays on, and the Power light ashes slowly.
Once defrosting is complete, the unit will return to its previous operating mode, the defrost
light will turn o, and the Power light will stop ashing.
Timer Function
To set the timer, power on the unit and press the TIMER button. The display will blink
“00H” or show the remaining time from a previous setting. Use the TIMER button within 3
seconds to cycle through time settings from 00H to 24H, increasing by one hour with each
press. Once the desired time is selected, stop pressing. After 3 seconds of no input, the
display will stop blinking and show the remaining time, conrming the timer is active.
When the countdown ends, the machine will automatically shut o, and the timer setting
will clear. If the timer is set to 00H, it will cancel the previous timer. Turning o the machine
manually will also cancel the timer. In the case of a malfunction, the timer setting will be
retained.
Temperature Display Function
The display shows the ambient temperature. By default, the unit displays in Celsius,
indicated by the “°C” light. Press the UNIT button to switch the display to Fahrenheit (“°F”
light will appear). Press the UNIT button again to return to Celsius.
Drainage Function
When using gravity drainage:
1. First, remove the water plug to empty any residual water from the machine.
2. Insert the gravity drainage hose and ensure it is securely fastened before turning on the
dehumidier. Ensure the end of the hose is not higher than the gravity drainage outlet.
3. If the unit begins to leak while elevated and properly leveled, check the drainage outlet
to ensure it is not clogged, and verify that the hose is not bent or kinked.

Drainage Function
When using gravity drainage:
Remove the water plug to release any remaining water from the unit before setup.
Securely attach the gravity drain hose. Ensure the end of the hose is lower than the
drainage outlet before turning on the dehumidier.
If the unit stops running and the operation light blinks slowly with an E4 error on the
display, check the hose for clogs, kinks, or bends. Clear any obstructions—once the
drainage path is clear, the error will reset and the unit will resume normal operation.
If the unit leaks while elevated and level, inspect the drainage outlet for blockages and
verify the hose is properly connected and free of bends or kinks.

Using the Pump Drainage Function
1. Plug the gravity drainage outlet with the water plug. This is required when using the
pump drainage option.
2. Unscrew the nut on the pump drainage outlet. Pass the drainage hose through the nut,
insert the hose into the outlet, and securely tighten the nut onto the unit’s metal nozzle.
3. Press and hold the DRAIN button for 3 seconds. The unit will beep, and the pump mode
indicator will light up, conrming activation of the water pump function.
4. While in pump mode, briey press the DRAIN button to manually activate a 28-second
drainage cycle.
If an E4 error appears, check if the pump hose is blocked, kinked, or bent. Clear any
obstructions or disable the pump mode. Once the issue is resolved, the E4 error will clear
and the unit will resume normal operation.

Dehumidier Storage:
If the device will be stored for an extended period, follow these steps:
1. Turn o the machine and allow it to dry.
2. Coil the power cord and store the drainage hose.
3. Place the dehumidier in a clean, dry location.
ENERGY SAVING TIPS
1. Adjust the humidity setting to the highest comfortable level to reduce the amount of
time the dehumidier runs. If it feels humid or “musty”, lower the humidity setting. To save
energy, turn o the dehumidier when you open the windows, just as you would turn o
the air conditioner.
2. If you’re going to be away from home for an extended period of time in the summer,
set the relative humidity to 55% and set the thermostat to the highest temperature you’re
comfortable with in cooling mode. This will keep humidity at a manageable level while
minimizing cooling energy consumption.
OPTIONAL REMOTE CONTROLLER
This dehumidier supports remote control through a dedicated external controller,
connected to the dehumidier via a network cable, enabling you to manage the unit
remotely.
The remote controller is especially useful when the dehumidier is located in a hard-to-
access area, allowing convenient monitoring.

• Dehumidier Lock-On A/C Sensor Feature:
Automatically activate the dehumidifier when the air conditioner runs.
When using A3-A4 function, first to open the machine cover board will switch the
motherboard, to the position of “ON”.
• Activate Dehumidication When the A/C is Running
To enable the Lock-On dehumidifier function, follow these steps using a voltmeter to
ensure correct wiring from the A/C transformer:
1. Connect the common wire from the existing A/C transformer (usually Black) to the “COM”
sensor terminal between “ON-D” on the unit.
●
Tip:
Identify the common wire from the A/C transformer reading 0 volts between it and
the Yellow air conditioning call for cooling wire. An incorrect wire will yield a 20 V to 28 V
reading.
2. Add another Yellow wire to the thermostat Yellow terminal and run it to the “ON-D”
sensor terminal on the unit.
Note:
A5-A6 functions serve as external water pump functions. If these two interfaces
remain continuously connected for 14 seconds, the machine detects an E4 error, causing
the unit to stop. Resolve the E4 error by restarting the unit.
