Installation Sketch
Installation of the ceiling-mounted dehumidifier should be divided into two parts: installation of the dehumidifier and connecting ducts.
Before installation, you need to choose and determine a good installation location from professional installation perspective first, (if you have decoration drawings, it is best to negotiate with the designer before the installation).
1. HANGING INSTALLATIONMark the accurate positions, drill Φ6 holes and install expansion threaded rods. Then hook the machine to the threaded rods.
① Please keep the machine horizontal when installing. Any inversion could cause damage.
② After the dehumidifier is installed, need to check whether the machine has been installed horizontally by level tools (to ensure that the dehumidifier can drainage water normally and avoid water leakage).
The air inlet duct should be as close as possible to the machine, and the height difference with the air inlet of the dehumidifier itself should be as small as possible. The shorter the air inlet duct is, the better the dehumidification effect will be. The length of the air inlet duct should not exceed 1 meter, and it should be closely connected with the air inlet of the dehumidifier (there should be no obstacles in front of the air inlet).
Ceiling-mounted dehumidifiers can be installed on the ceiling or suspended with steel hanger. When it is suspended, the height of hanging space should not exceed 20cm. After installation, it should be easy to operate to circulate the air.
Note: The access panel of this unit shall not be less than 45*45cm which is the minimum size that the dehumidifier can be removed through.

Precautions For User
- Use the machine on flat firm floor inside room. Don't put objects in front of air inlet for better efficiency.
- Don't use the machine in the environment with combustible, explosive, corrosive air or dusty. Do keep at least 50cm space for ventilation around the machine.
- Please use the machine away from heat for less power consumption.
- The working temperature range of machine is 5 ℃ ~ 38 ℃. The protection of compressor will be acted if use it in the environment temperature higher than 38 ℃ and stop running automatically, it will reduce the working life of the machine. Below 5 ℃, absolute humidity of the environment is quite low, do not use the machine if not necessary.
- Do make sure to leave at least 50 cm from wall to air inlet and at least 50 cm from wall to air outlet when the machine used against a wall, otherwise it will affect the dehumidifying effect or cause machine failure.
- Do not incline the machine exceed 45 degrees in moving or installation. Do correctly assemble the drain pipe for drainage.
- In the low temperature condition, the defrosted water will be frozen gradually at the outlet, please don’t open the machine until all the ice melted to avoid water overflow to room from water collector.
- Please clean the filter net regularly in using machine, make necessary isolation measure when use in the dusty environment to avoid malfunction and raise the working life.
- Don’t cut off the power or pull out plug when machine running. Don’t damage the power line or make any change.
- Don’t put fingers or sticks into the air outlet.
- Don’t do any change of machine unless guiding by our technicians.
Control Panel
Fault Code Indication
| Code | Description | Solutions |
|---|---|---|
| E1 | Coil temperature sensor error | check the data wire or replace new sensor |
| E2 | Room humidity sensor error | check the data wire or replace new sensor |
| E3 | Phase sequence error | check the power supply or wire connection |
| E4 | Phase missing | check the power supply or wire connection |
| E6 | Compressor pressure protection | Fill enough refrigerant and check the leakage point |
Common Faults Removing
| Failure phenomenon | Cause Analysis | Processing method |
|---|---|---|
| The machine is not running | Power cut | Restore the power |
| Power is not normal | Restore power | |
| Power plug is not plugged in | Put plug into the receptacle | |
| Fuse blowout | Replace the fuse | |
| Poor dehumidification function | Filter Clogged | Clean the filter |
| Air inlet and outlet blocked | Remove obstructions to make good ventilation | |
| Windows and doors is not closed | Close doors and windows and vents | |
| Refrigerant leakage | Contact for maintenance | |
| Cannot reach suitable humidity level after long time running | Doors and windows are not closed | Close doors and windows and vents |
| Vapor source existed in the room | Close vapor source | |
| Room too large | Provide right room size to buy correct machine and quantity | |
| Noise abnormally | The machine placed not stably | Place the machine stably |
| Filter Clogged | Clean the filter |
1. When the malfunction can not be removed and recognized, please contact the supplier for maintenance service, do not attempt to disassemble the machine to repair without guide.
2. When dehumidifier is running or stopping, you will hear the sound of refrigeration cycle, it is a normal phenomenon, not a fault.
3. Discharge hot air from outlet is a normal phenomenon.
Schematic & Circuit Diagram
Dehumidification principle
Under the condition of normal startup → through the operation of the fan → moist air is sucked in from the air inlet → through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → dissipates heat through the condenser → blows out from the air outlet.
Refrigeration principle
The high temperature and high pressure gas is discharged through the operation of the compressor → the exhaust port → enters the condenser for cooling → becomes a low temperature and high pressure gas → intercepts the flow through the capillary → becomes a low temperature and low pressure liquid → evaporates and absorbs heat through the evaporator → returns to the compressor and becomes a low temperature and low pressure gas.

Protection Function
A. When the dehumidifier is automatically frost, the compressor stops running, the fan continues to run, the frost lights are on, and the running lights are on.
B. After the compressor delays the protection function, the compressor is automatically delayed after 3 minutes.
C. When the temperature and humidity sensor is abnormal, the compressor and fan are turned off, the running lights are flickering, and other indicator lights are extinguished. At this time, all keys cannot work. After the sensor failure is eliminated, the key should be re-opened to work normally.
