Important Notice

• Always keep the devices in the vertical position, on the flat surface and certainly at all times.
• Make sure the minimum of 300mm (1”) between the edges of equipment and any flammable materials.
• Don’t hide the air suction inlet and radiator grille from the devide.
• For indoor use only.
• Not suitable for use in cabinet, closet, boats, caravans or similar locations.
• Leave the unit to stand for one hour before connecting to the mains supply after transport or when it has been tilted (e.g. during cleaning).
• The mains supply must conform to the specification shown on the rating plate at the back of the unit.
• Avoid overloading circuits, which is caused by using more electrical amps than your wiring can support. Overloading electrical wires can cause excessive heat and electrical fires.
• Avoid being abandoned.
• Check the power cord carefully. Make sure that it is not punctured or frayed. Inspect the plug to ensure that the prongs are secure and the plastic surrounding it is not cracked.
• Do not suddenly unplug the power plug while the machine is operating. Before turning on or off the machine must use switch on the control panel.
• Before moving the unit, turn off all controls, then unplug and empty the water tank.
• Don’t use bug sprays or other flammable cleaners on the unit.
• Never pour or spray water over the unit.
• This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.

• Only a licensed professional is allowed to dismantle or modify the appliance.
• Suggested to send the appliance for professional maintenance periodically.

Function of the Button

2.1 Operation

2.2 Features

1. If the set humidity is higher than the ambient humidity, the dehumidifier will enter the “wet control state” and will not run.
2. When entered dehumidification mode, the fan is turned on for 5 seconds to start the compressor; when the dehumidifier stops working, it will first turn off the compressor, then turn off the fan after 30 seconds;
3.  After the compressor is turned off, it takes 3 minutes to restart. When the compressor is running for 72 hours, the system will automatically resume after 30 minutes of forced stop.
4. When running at a lower temperature, the machine will automatically detect the system temperature. When reached the defrosting temperature, it will automatically stop and defrosting. The “snow pattern” will light up and the “defrosting pattern” will shine. After the defrosting, the dehumidifier starts automatically.
5. Humidity control operating range: 10%~90%.
6. If the dehumidifier is not used for a long time, remove the power cord or power off.
7. The function of the memory system, the function can function before the power is tured off in 72 hours after the power is lost. (Note: When you leave the humidifier, please turn off the source)

Operating Instructions

When the substrate is powered on for the first time, the substrate enters the standby state, press the power button and set the required humidity 3% less than the current humidity to enter the running state, If the setting humidity is higher than ambient humidity, the dehumidifier will not work.
3.1 Dehumidifying Running

1. When the compressor has passed the protection for 3 minutes and the indoor humidity ≥set humidity +3% RH, the compressor will work again.
2. When the indoor humidity <set humidity -2% RH, the compressor is turned off.
3. Set humidity -3% RH <indoor humidity <set humidity +3% RH to keep the original compressor working.
4. The compressor stops the fan if it has not been operated for 3 minutes after the humidity has dropped.
5. Defrost
   A) After the machine starts to run for 30 minutes, the copper head coil sensor starts to detect the tube temperature. When the tube temperature is ≤-1 °C (there is 3 seconds of detection time), the compressor stops and the fan runs, and the defrosting  operation starts. The lights are shining.
   B) When the temperature sensor detects that the evaporator coil temperature is greater than or equal to 5 degrees and the detection is greater than or equal to 5 degrees for 3 minutes, the defrosting is exited

3.2 Drain Indicator
Water level floats
Do not remove the float from the tank. If the float in the tank is removed, the machine will not turn on or start.
Put water tank back.
When placing in the water tank, use both hands to push the water tank into the correct position. If the water tank is not placed, the machine will not be able to start or after operation the water will overflow.
Continuous Drain
This product has a continuous drain hole that is connected by a plastic tube (inside diameter is 12through which water can be drained. When using a water pipe, do not immerse the water outlet in the water to prevent the pipe from being too long or the pressure is formed in the pipe when the water outlet is blocked. The water flow is not smooth, resulting in water leakage.

First, insert the drainage hose into the drainage port on the side of the water tank, and then put the water tank back into the dehumidifier. Note that the outlet of the water pipe should extend out from the drainage hole of the dehumidifier.

Inspection and Maintenance

Parts| 1-3 months| 12 months
Filter| Clean the filter|
Compressor| Check if the compressor is normal and the vibration is normal.| Check the compressor cable for signs of
looseness, aging, and damage.
Heat Exchanger| Clean the duct and sundries.|
Seal| Check for signs of damage or displacement. If it is worn or damaged,
it should be replaced in time.| Check for signs of damage or displacement. If it is worn or damaged,
it should be replaced in time.
Temp. Control| | Check if all external temperature and humidity probes are working properly.

Device Installation

The dehumidifier can be installed in many occasions and customized according to the needs of user.
Electrical Connection

1. The dehumidifier cannot be operated at voltages and frequencies outside the manufacturing range.
2. Before switching on the main power supply, the AC power should be checked to ensure that the supplied voltage fluctuation range does not exceed ±10% of the voltage and frequency indicated by the equipment. This check is especially important for voltage fluctuations that can occur in high load situations.
3. The dehumidifier must be grounded and a power disconnect switch set to ensure that the unit is powered off during inspection and service.
4. The fuse current of the power supply fuse is 1.5 to 2 times the rated current of the installed dehumidifier. The fuse should be installed in the dehumidifier attachment. The power supply cable and main fuse are optional to handle the correct operating power of the dehumidifier. Fuse rating: 10A 250V, 16A 250V.
5. If the power cord is damaged, it must be replaced by the manufacturer or a professional authorized person in order to avoid danger.
6. Placing. When the dehumidifier is working, make sure Minimum distance between air inlet and other articles is 80cm
   Minimum distance between two machines is 400cm
   Minimum distance between air outlet and other articles is 400cm
   Minimum distance between the back and the wall is 10cm

[The best position is placed by opposite instead of in the same line. Otherwise the right side dehumidifier will detect more dry air generated by the left side dehumidifier instead of the room’s wet air. ]
