Working Principle
1.Refrigeration
Using cycling vapor compression refrigeration system,when the compressor work, indraft low temperature and
pressure refrigerant gas from evaporator, compressed by compressor into high temperature and pressure gas,
and then into the condenser to condense into liquid, meantime release heat, after throttling under the function of
the thermal expansion valve, entering into the evaporator and absorbed heat,then evaporate into gas, finally
back to the compressor through the suction tube and complete a refrigeration cycle ; On the other hand,through
changing of refrigerant flow direction, total or partial condensing heat generated from refrigeration can be
exhausted to outside,to achieve the purpose of adjusting the indoor temperature.
2. Dehumidification Principle
When the wet air flows through the evaporator surface, the air temperature will drop, when it falls below the dew
point,the steam in the air will condense out, gathering and drainage of water pipes in the receiving plate, the
controller automatically adjusts the compressor start-up time according to the setting humidity , so as to achieve
the purpose of adjusting humidity.
3. Heating
Electric heating compensation.

Installation
Disconnect electric power from the appliance before performing any maintenance or repairs,failure to do so
could result in death or electrical shock.
Because of potential safety hazards under a certain condition, we strongly recommend against the use of an
extension cord. However, if you still elect to use an extension cord, it is absolutely necessary that it will be a
related national standard LISTED 3-wire grounding type appliance extension cord having a 3- blade grounding
plug and a 3-slot receptacle that will plug into the appliance. The marked rating of the extension cord shall be
220V 15A.
Installation Conditions
1. After the unit is installed, the inclination angle of the installation plane cannot exceed 1 degree, and the
installation bracket or platform should be able to bear the weight of the unit.
2. In order to ensure good ventilation performance of the unit and daily maintenance and repair, it is required to
leave enough space for machine disassembly and maintenance work.
3. There should be no strong magnetism, steam, or dust around the unit, meantime, ensure that there are no
heat sources, corrosion, and combustible gases in the installation area.
4. After the unit is installed, there should be enough heat dissipation space on the condensing side to ensure
ventilation.
* The ventilation and heat dissipation of the unit play a vital role in the normal operation and performance
guarantee of the unit. When the unit is running in ‘constant temperature’ and ‘automatic’ mode, a large amount of
heat will be generated on the condensing side of the unit. In order to dissipate the heat smoothly, the condensing
side of the unit needs to be ventilated well, otherwise it will affect the unit’s overall performance and lifespan. If
there is no ventilation on the condensing side of the unit, it is necessary to install an exhaust fan for forced
ventilation.

B- Stainless steel duct, 20mm insulation
8. When connecting the air duct, supply air flange cover and return air flange are recommended to choose.The
connection between the air duct and the unit should be sealed without air leakage.
9. If the unit is installed in a high-temperature and high-humidity environment, it is recommended to paste rubber
and plastic insulation cotton with a thickness of more than 10mm on the surface of the unit to avoid condensation
on the surface of the unit.
10. If the unit is connected to the air duct to supply air, it must be ensured that the pressure loss of the air duct
does not exceed the static pressure outside the unit. (It is recommended that the total length of the air duct
should not exceed 6 meters, and the air flow in the air duct should not exceed 3m/s.) If the condensing side of
the unit is installed outdoors, an air conditioner rain cover should be installed.

Through the 8 fixing holes on the front of the flange bracket, use screws to fix the flange on the wall, make sure
that the screws are flush with the flange surface of the bracket, and must not be over-tightened or over-loose.
5. Mounting the unit
Slide the unit in along the mounting flange bracket. Slide the condensing fan side of the device into the bracket
until the desired depth is reached, making sure that the humidification solenoid valve and power cord of the
device do not touch the flange of the bracket.
6. Seal all cracks and gaps
Seal all cracks and gaps around the unit with an airtight sealant or caulking to prevent air leakage and movement
of the unit
7. Attach the condensate drain line
Note: The drain line must be connected well before starting the unit.
There is a condensate drain hole at the bottom of the unit on the condensation side, and the diameter of the
condensate drain is DN15
a. It is recommended to connect the water seal at the bottom of the condensate drain pipe, and the other end of
the drain pipe should be placed in a bucket or directly connected to the drain pipe;
b. If the other end of the drain pipe is placed in a bucket, the bucket must be emptied in time to avoid water

１１
overflowing the bucket or prevent mold from water growing. If the machine runs for a long time, it is
recommended to connect the drain pipe to the open floor drain or sink.
c. The drain at the bottom of the unit needs to be connected to a water seal. The size of the water seal is shown
in the attached picture (users prepare the water seal by themselves).
8. Connect the water inlet pipe
Note: The water inlet pipe for humidity must be connected well before starting the unit.
There is a humidification water inlet interface on the right side facing the air outlet of the unit, and the diameter of
the humidification water supply pipe is DN08
a. Connect the manual water flow regulating valve to the humidification water inlet pipeline.
b. Purified water is preferred for humidification. If there is no pure water, tap water can also be used. Avoid
limescale as much as possible, or it will affect the humidification effect.
c. To better control the wet-film water inlet flow rate, electromagnetic water valve and water flow gauge are
suggested to be installed. Otherwise, the water will always be supplied to the machine in a normally open state,
which will cause the equipment to leak and fail to operate.
