III. Working Principle
All fresh air with moisture goes through air filter and enters the
evaporator.As the temperature of evaporator surface is lower than dew point temperature of moisture, the moisture will
be condensed into water drops and be collected to water tray, and then flows to bottom tank. The collected water is
treated with activated carbon filters, reverse osmosis (RO) and sterilization by Ultraviolet device to be processed into
drinking water or for other uses.
The output water quality meets the standard GB5749-2006 of P.R.C.
Ⅳ. Machine Receipt, Installation and Adjustment
1. Machine Receiving
Please check the machine and spare parts according to packing list.
2. Installation
2.1 Crane and forklift should be used for the transport and installation. Handle with care. When crane is rigged to the
machine, ropes must be of same length and the hanging angle must be more than 45 degrees to avoid damage or
scratching to the machine. The hanging ropes must be strong enough for the operation.
2.2 The machine must be placed on level ground and be a certain distance from buildings; 1 meter at least between
air inlet of condenser and the building, 1.5 meter for air exhaust. Place the machine in a place without direct
sunlight and away from heat source preferably covered from rain and sunshine. There should not be barrier effecting
ventilation around the air inlet and outlet of the machine. Do not run the machine in circumstances of alot of dust
or serious chemical pollution.
2.3 The machine should be equipped with independent power supply system and power distribution cabinet. The user
should also provide a master air switch. When there is a big fluctuation in electrical voltage, the machine must be
equipped with independent voltage regulator. The power supply adopts 3-phase 4-wire system phase. Voltage
deviation should not be exceeding 10% of the rated value. The maximum allowed unbalance in phase voltage is 2%.
The machine must have a reliable earthing to ensure personal safety.
2.4 Check the machine and see if there is any partial damage or deformed parts during the transport. Check all wirings if
there is any loosening.
2.5 Connect power cables as per Picture 2.5.1 (Use cable with designated size or thicker size)
2.5.1
3. System Adjustment
After the machine’s arrival, positioning and installation is completed, please check up the following before
connection to electricity.
3.1 Checkup before switching on the machine.
!Notice：Phase voltage unbalance exceeds 2%. Do not turn on.

-- 3 --
3.1.1 Check if the refrigerant is leaking or not. Indicative value of pressure gauge is not less than 0.7MPa at high and
low balance when left for a long downtime. （This value varies with ambient temperature，Normal conditions (ambient
temperature > 15 degrees) should not be lower than 0.7MPa.If less than 0.7MPa, refrigerant may leak）Check all joints
of cooling system to see if there is any obvious oil stains or not. There would probably be a gas leakage if such oil stains
found. Please call professional maintenance support to repair and redo vacuuming and gas feeding.
3.1.2 Use megohmmeter to check all power cables and control wiring to be in position.
Make sure there is no short circuit, and the earthing is in good condition. Check all
wiring connections are tight. Check again whether the N-wire is connected, if the N-wire
is connected incorrectly, it will cause the circuit board to burn out.
3.1.3 Switch on the master power supply. Check whether the Phase Sequence
Detection Indicator is on，If the NORMAL light is on, it will be normal. If the other lights
are on, it will be restored after the power is cut off and connected correctly. .
3.1.4 After the master power supply is switched on, turn the E-STOP button clockwise
and the red power lamp will be on. Oil heater of compressor automatically electrified,
Make sure that the oil heater is energized for more than 1 hour when it is first
started or when it is not working for a long time.
3.1.5 Check the setting value of high- and low-pressure controller. High pressure:2.8MPa, Low pressure:0.23MPa,
Return error:0.3MPa. Based on machine running test value。Notice：The set value is based on the display value of the
high- and low-pressure gauge when the machine is running. It has been set before leaving the factory. If there is
no trouble, please do not adjust it. 。

Ⅶ. Maintenance
1. During the daily running, it is required to check all meter’s indication to be in normal range. Avoid rain or too much
moisture on electric components which would cause electricity shorting. If such problem is found, dry the
components with care.
2. Always monitor the working status of compressor and fan motor, make sure the running sound is normal. If there is
any strange noise or abnormal sound, switch off the machine and call professional maintenance service for checkup
and repair.
3.Thermal expansion valves and other refrigeration components such as drying filters, solenoid valves in the main
circuit should work normally. Filters, drying filters, main circuit solenoid valves in front of thermal expansion valves，
at high pressure，the temperature difference between the inlet and outlet pipes should not be obvious，nor should there
be dew or frost on components. Replacement of refrigeration components or troubleshooting of refrigeration systems
must be done by professionals.
4. Always check the joints between various parts are tightened and firm, particularly the join bolts of electric
components and conducting wires cannot be of any loose or have moisture. Make sure the wiring is tightened and
firm.
5. Clean the surface of machine regularly to keep it clean. Do not use any detergent, organic solvent (e.g. Lacquer
Thinner) or other solvents containing acid or alkali to clean the painted surface.
6. Air filter should be cleaned regularly subject to the local working conditions. Normally it should be cleaned once a
week. Use soft brush to clear dust first and then clean with water or detergent. Dry it in room air. (See Annex III)
7. Always check the condenser if there is dust or dirt on the surface. Clean the surface regularly with neutral warm
solution and soft brush. Avoid damage to the flakes.
8. Always check the joins in compressor compartment if there is obvious oil stains or not. If such oil stains found, it
indicates the cooling gas would be leaking. Call professional service for repair and redo vacuuming and gas filling.
9.The machine must be upright when loading or handling. If it needs to be inclined, the angle between the machine and
the ground is no more than 45degrees.
