1. Safety Instructions
1.1 Safety and warning
The ceiling dehumidifiers meet the safety requirements of the European standards and
specifications and give consideration to the safety of personnel and equipment in design and
manufacturing. In each chapter of this manual, there is safety information, as well as a clear
expenditure of dangerous operations, and a warning function of the danger symbol is marked
in the front. This manual provides the best dehumidifier operating experience and procedures,
but these recommendations are for guidance only and any personal responsibility is not
assumed. When installing and operating equipment, local safety regulations must be
complied with, and everyone must assume the following responsibilities:
Protect the safety of the equipment according to the description and instructions in this
manual. Take care of yourself and others.
Dehumidifier must be operated and maintained by personnel with relevant professional
qualifications.
Electrical parts must be maintained by authorized electrical installers.
It is forbidden to install dehumidifier in the area with explosion-proof device.
Before opening any maintenance panels, make sure that the power to the dehumidifier is
turned off.
When the operation is completed, the dehumidifier should be cooled for at least 15 minutes
before maintenance operations.
If dehumidifier is not maintained, the maintenance panel should be closed.
Dehumidifier is limited to dehumidification of air under normal atmospheric pressure.
It is forbidden to use dehumidifier without the installation of filter device, otherwise it will
cause the heat ex-changer of the dehumidifier to be dirty or corroded, which will eventually
lead to the dehumidification ability become weakened or even lost.
It is forbidden to delete or alter the mark and description on the equipment.
Spare parts with original design shall be used.
1.2. Working condition
The ceiling dehumidifier adopts direct evaporative cooling design, which can dry air under
atmospheric pressure. The equipment can dehumidify air in the 100%RH humidity range and
the temperature range is 5-38 ℃. It is widely used in hotels, office buildings, hospitals,
commercial residences, research laboratories and other places. Its working principle is that
the fan will cool and dehumidify the indoor air or the mixed indoor and outdoor air through
the heat exchanger and then re-heat up and send it back to the room to reduce the indoor
humidity, so as to provide a more comfortable living environment.

6
1.3. Contents of the manual
This manual is for dehumidifier users, including installation, operation, maintenance and
basic fault analysis. The ceiling dehumidifier described in this manual has a system air
volume of 5600 m3/h and a dehumidifier capacity of 20L/h. It is used to extract air from the
central area of the building and deliver the treated air to individual rooms.
2. Equipment Introduction
2.1 Product description
The dehumidifier is designed to meet the requirements of IEC protection level IP21.
2.2 Equipment principle
The fresh air is initially filtered by the filter and sucked into the machine by the fan. It is first
cooled by the evaporator. When the temperature drops to the dew point of the air, the water in
the air will condense out and reach the water tank by the sink below the evaporator. The cold
air that has been dehumidified passes through the condenser to make the air temperature rise,
which can prevent the indoor temperature from falling, and at the same time can make the
condensation pressure of the refrigeration system drop, improving the cooling efficiency.

3 Equipment Installation
3.1 Introduction
Ceiling dehumidifier can be installed in different places according to the requirements. It can
also be used together with the existing power system or air duct system if required. This
section describes the design of dehumidifier from the factory to the installation of the
equipment required to work, read before the installation of equipment to help the correct
arrangement of work.
3.2 Shipping and storage
In order to ensure the quality and reliable performance of dehumidifier, each equipment has
been inspected before delivery. If dehumidifier needs to be stored for a period of time before
installation, please note:
Factory packaging should not be removed.
Where the equipment is stored can effectively avoid physical damage.
Store under cover to protect against dust, rain and frost.
3.3 Open the case for inspection
Disassemble the shipping package of the equipment and inspect the product to confirm that
the equipment was not damaged during the shipping. If any damage is found, please contact
the equipment manufacturer. If the pipeline connected to the dehumidifier equipment has
been arranged, it should be checked whether the pipeline layout is appropriate. If the
environment and installation conditions are not satisfactory, please contact the manufacturer.
3.4 Movement of dehumidifier
This series of dehumidifier can be carried by forklift, in order to prevent equipment damage
and personnel injury, it is recommended to use the equipment.
3.5 Selection of installation location
For optimal operation and troubleshooting, the ceiling dehumidifier should be installed
indoors. During installation, a maintenance space should be left at the rear of the
dehumidifier to facilitate future inspection and maintenance of the equipment. It is very

8
important to keep the necessary and compact service space for cleaning and maintenance
purposes. To prevent condensation inside the dehumidifier, the unit should not be exposed to
temperatures below the dew point of the process air.
The equipment should be placed in a place close to the socket equipment and easy to
connect.
When the equipment is needed and installed, sufficient maintenance space should be
considered.
3.6 Basic installation conditions
Dehumidifier must be installed horizontally, please be sure to use a level to measure the
equipment after installation of the horizontal Angle. Prevent condensation water residue,
resulting in unit leakage damage to the entire environment.
3.7 Air duct connection
If the air outlet is connected to an air duct, the size of the process air duct shall comply with
the recommended value of ISO7807. For the installation of air duct and elbow flange pipe
joints, the bolt length should not exceed 20mm. For an ideal installation, the air is extracted
from the central area of the room, dehumidified and then distributed to each individual room,
such as bedrooms, offices. When installing the return air outlet and outlet connecting pipe of
the dehumidification unit, the following suggestions should be paid attention to:
Minimize duct length to reduce air system static pressure loss.
To ensure performance, all rigid (galvanized) pipe connections must be airtight.
The air duct should be insulated to avoid condensation on the outer wall of the duct
when the airflow temperature in the duct drops below the dew point temperature of
the outside air, which will cause corrosion of the duct; and to avoid energy loss.
Piping installed directly on the dehumidification unit should be adequately supported
to reduce loads and pressures due to pipe gravity and operation.
If the system is introduced into the dehumidification unit by outdoor fresh air, the air
inlet should be sufficiently high from the ground to prevent the inhalation of dust and
debris. The entrance must be away from possible pollution sources, such as energy
waste, steam and harmful gases.
Dehumidifier can be installed in the room to be dehumidified or in a separate room.
To ensure optimum dehumidification, the fan outlet should be equipped with a
diffuser.
3.8 Water pipe connection
A U-shaped pipe needs to be installed on the drain pipe of the unit. If there is no U-shaped
pipe, due to the negative pressure inside the dehumidifier, there will be airflow from the
drainage pipe into the hanging cabinet, airflow will prevent condensate water into the
drainage pipe, is the condensate overflow of the unit. U-shaped pipe can close the negative
pressure area of the dehumidifier, so that the water from the water tray can flow naturally into
the drain pipe. Try to make the U-shaped pipe connected to the drain pipe and the ground
parallel. A 3/4 inch threaded pipe should also be installed to connect the reserved drain to the
floor drain or toilet.

9
3.9 Electrical connection
!
Electrical connections must be performed by qualified personnel in accordance with the
electrical standards of the location where the equipment is located.
The control circuit of the dehumidifier has been marked with different colors to prevent
confusion. The design of the unit adopts single-phase AC power supply, and the installation
and configuration of electrical equipment are in accordance with the voltage and frequency
calibrated on the equipment nameplate.
The power supply of the dehumidification unit is equipped with a leakage protection
device to make the unit safer.
To ensure optimum dehumidification, the fan outlet should be equipped with a
diffuser.
The dehumidifier must not be operated at voltages and frequencies outside the range
of manufacture.
Before the unit is connected to the main power supply, check the single-phase AC
power supply to ensure that the fluctuation range of the supplied voltage does not
exceed ±10% of the marked voltage and frequency of the equipment. This inspection
is especially important for high load applications (due to the conversion of large
electrical equipment) that can cause voltage fluctuations.
The unit must be grounded and equipped with a power isolating switch to ensure that
the power is cut off during inspection and service of the equipment.
The fusing power of the power supply fuse must be consistent with the power and
type of the installed dehumidifier. Fuses should be installed near the dehumidifier.
The selection of power supply cable and main fuse should correspond to the correct
operating power of the dehumidification unit.
3.10 Connection of external sensors
!
Note: The dehumidifier can be arranged in advance to cooperate with the external
control system, providing wiring blocks for connection to the external control system. When
installing the humidity detection element, its installation position should follow the following
requirements:
To ensure optimum dehumidification, the fan outlet should be equipped with a
diffuser.
Do not install the panel in a place where the relative humidity cannot be accurately
detected, such as near a window or water source.
The humidity detection element shall be installed at a height of 1 to 1.5 meters above
the ground to detect a representative level in the controlled area, or the installation
design shall require it to be installed at a monitoring point.
The detection element shall be installed where it is not affected by dry or wet air and
unexpected airflow in the control area.
The humidity probe should not be placed near the heat dissipation equipment or
exposed to direct sunlight, because the temperature change will affect the actual
detection value.

10
The external control system must be compatible with the low-voltage control circuit
of the dehumidifier.

2. Giới thiệu sản phẩm
2.1 Mô tả sản phẩm
Máy hút ẩm được thiết kế để đáp ứng các yêu cầu của tiêu chuẩn IEC IP21.
2.2 Nguyên lý hoạt động
Không khí ban đầu được lọc bởi bộ lọc và được quạt hút vào máy. Không khí được làm mát
bởi giàn lạnh. Khi nhiệt độ giảm xuống điểm sương của không khí, nước trong không khí sẽ
ngưng tụ và đi đến bình chứa nước bằng máng nước bên dưới thiết bị bay hơi. Không khí
lạnh đã được hút ẩm đi qua dàn ngưng tụ làm cho nhiệt độ không khí tăng lên, có thể ngăn
nhiệt độ trong nhà giảm xuống, đồng thời có thể làm giảm áp suất ngưng tụ của hệ thống
lạnh, nâng cao hiệu quả làm lạnh.
