Please read all the instructions carefully before using the machine.
- Do make sure the power supply is 380V/50Hz before power up the machine.
- Don’t power on/off the machine by connecting/cutting the power supply.
- Don’t roll or damage the power cord when install or remove the machine.
- Don’t put finger or any other rod like object into the machine.
- Do cut off the power cord before cleaning or maintain the machine.
- Don’t use in narrow and sealed space, make sure to connect the ground lead.
- Don’t do any change of machine unless guiding by our technicians.
Attention: The machine has loss and dislocation phase protector. When the connected three phases outer power supply is not correct as the machine setting, the protector will be disconnected, all the indicators on the control panel will regularly display, but the machine will not run. Please correct the power supply phase connection, and restart the machine at this condition. This operation requires professional electric technicians.
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 a professional installation perspective first (if you have decoration drawings, it is best to negotiate with the designer before the installation).
1. HANGING INSTALLATION
Mark the accurate positions, drill Φ6 holes and install expansion threaded rods. Then hook the machine to the threaded rods.
Mark the accurate positions, drill Φ6 holes and install expansion threaded rods. Then hook the machine to the threaded rods.
WARNING:
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 drain water normally and avoid water leakage).
2. AIR INLET DUCT INSTALLATION
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 a steel hanger. When it is suspended, the height of the 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.

■ Attention：The product size is slightly deviated with the physical object, which is subject to the real thing!
Precautions For User
- Use the machine on a flat firm floor inside the room. Don't put objects in front of the air inlet for better efficiency.
- Don't use the machine in environments with combustible, explosive, corrosive air or dust. 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 the machine is 5 ℃ ~ 38 ℃. The protection of the compressor will be activated if used in ambient temperatures higher than 38 ℃, stopping run automatically, which 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 the wall to the air inlet and at least 50 cm from the wall to the air outlet when the machine is 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 low temperature conditions, the defrosted water will freeze gradually at the outlet. Please don’t open the machine until all the ice has melted to avoid water overflowing into the room from the water collector.
- Please clean the filter net regularly when using the machine. Take necessary isolation measures when used in a dusty environment to avoid malfunction and raise the working life.
- Don’t cut off the power or pull out the plug when the machine is running. Don’t damage the power line or make any changes.
- Don’t put fingers or sticks into the air outlet.
- Don’t do any changes to the machine unless guided by our technicians.
Attention: Install the machine stably with a screw suspender on the ceiling, and make sure there is over a 2-degree slant angle to the drainage tube for smooth continuous drainage.

3. Discharging hot air from the 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 defrosting, 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.
Frequently Asked Questions (FAQ)
What are the power requirements for this industrial dehumidifier?
Before powering up the machine, make sure the power supply is 380V/50Hz. The product features optional voltages of AC277V and AC220V depending on the exact hardware configuration and power systems.
What should I do if the indicators display on the control panel but the machine does not run?
This indicates that the loss and dislocation phase protector has disconnected because the three-phase outer power supply connection is incorrect. You must have a professional electrical technician correct the power supply phase connection and restart the machine.
What is the maximum allowed length for the air inlet duct during installation?
The length of the air inlet duct should not exceed 1 meter. It must be kept as close as possible to the machine with minimal height difference, and there should be no obstacles in front of the inlet.
What is the operational temperature range for this dehumidifier?
The machine operates in ambient temperatures between 5°C and 38°C (and can dehumidify at low temperatures down to 41°F). If the temperature exceeds 38°C, the compressor protection will trigger and stop the unit automatically. It is not recommended to use the unit below 5°C.
How long is the warranty period, and is it compatible with other planting facilities?
These dehumidifiers come with a generous 5-year warranty. They are consistent with the hardware configuration of the well-known "Kuest" brand and offer a cost-effective solution when paired with NBSERO's planting facilities.
What do the error codes E1 and E2 mean on the control panel?
E1 indicates a coil temperature sensor error, and E2 indicates a room humidity sensor error. The recommended solution for both issues is to check the data wire or replace the sensor.
