    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.
    Attention:

    Install the machine stably with screw suspender on the ceiling, and make sure there have over 2 degree slant angle to the drainage tube for smooth continuously drain.

    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

    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.

    Maintenance Of Machine

    Do shutdown the machine and cut power before maintenance.

    General maintenance:
    Wipe the body with soft cloth in daily use. Use a wet hard cloth to wipe dirty body, or use a soft cloth moistened with a little diluted neutral detergent.

    Regular maintenance:
    Filter Cleaning: it will affect the dehumidifying effect or cause malfunction if accumulate dust on filter, it needs to be cleaned regularly, clean it at least once a month. Use dust catcher to remove dust or put filter into clean water (<40 ℃) to wash, then place filter back after cleaning.

    Attention:
    1. The filter cannot be put in sunlight directly or roasted to avoid distortion.
    2. The filter must be placed before power up machine.
    3. Long time of non-use, cut the power or unplug power line to put it in dry and shady place.
    4. Do not put down the machine to avoid damage and malfunction.

    Frequently Asked Questions (FAQ)

    Q1: What should I do if the control panel displays normally but the machine won't run?
    A1: This is likely due to the loss and dislocation phase protector. If the connected three-phase outer power supply is incorrect, the protector disconnects to safeguard the unit. Please contact a professional electric technician to correct the power supply phase connection and restart the machine.
    Q2: How often should I clean the filter net?
    A2: The filter net must be cleaned at least once a month. Accumulated dust will affect the dehumidifying efficiency or cause machine malfunction. Use a dust catcher or wash it in clean water under 40°C, and let it dry completely before reinstalling.
    Q3: What do the fault codes E1, E2, E3, E4, and E6 mean?
    A3: E1 indicates a coil temperature sensor error (check data wire or replace sensor); E2 indicates a room humidity sensor error (check data wire or replace sensor); E3 indicates a phase sequence error (check power supply or wire connection); E4 indicates a phase missing (check power supply or wire connection); E6 indicates compressor pressure protection (fill enough refrigerant and check for leaks).
    Q4: What is the optimal temperature range for using this dehumidifier?
    A4: The working temperature range is 5°C to 38°C. If used in environments above 38°C, the compressor protection will trigger and stop the machine automatically. Below 5°C, the absolute humidity is low, so operation is generally not necessary.
    Q5: Why does the machine blow out warm air and make a cycling sound?
    A5: Both of these are normal phenomena. Discharging hot air from the outlet is part of the refrigeration and heat dissipation process, and the sound you hear is the normal operation of the refrigeration cycle.
    Q6: What should I do if the machine is making abnormal noise?
    A6: First, check if the machine is placed stably on a flat, firm floor or properly secured to the ceiling. Second, check if the filter is clogged, as a blocked filter can cause airflow restrictions and extra noise. Clean the filter if necessary.
