Commitioning
The equipment requires fixed installation.
§
Open the maintenance panel on the dehumidification equipment and make sure that there are no impurities in
§
the equipment or electrical equipment box
Ensure that the main power fuse has an appropriate power rating. Check the built-in fuse.
§
5.2 Check before device startup
5.2.1
Duct
Check
Check whether the equipment is installed in accordance with the designed location and space requirements
§
Ensure that the air duct of the dehumidification system is connected according to the design requirements.
§
Place all dampers in the half-open position.
§
Check whether other components on the device are installed correctly, and whether the resistance of electrical
§
components is normal.
5.2.2
Wiring
Check
Ensure that the voltage and frequency of the power supply are consistent with the frequency of the power
§
supply required by the device.
Ensure that the supplied voltage meets the requirements of the equipment's electrical voltage, and the
§
voltage fluctuation range does not exceed 10% of the marked voltage and frequency of each electrical
equipment.
5.1 Introduction to Debugging
The equipment should be grounded and an isolation switch should be installed to ensure that the equipment
§
is insulated from the power supply during inspection and service.
The power of the isolating switch and the fuse must be consistent with the model and type of the installed
§
dehumidification unit.
The power supply cable meets the design requirements.
§
Make sure that the isolating switch is disconnected from the main circuit and the control on the panel is
§
turned off at the same time
Ensure that the equipment transportation package and useless panels have been removed.
§
Check that all wire connections are secure.
§
The control of the cabinet type dehumidification unit has been completed internally, and the indoor panel
control can be carried out according to the process requirements. Before starting the equipment, please be sure to
read the random technical manual and consult relevant technicians and experts to understand the operating
parameters and setting parameters of the equipment to avoid incorrect operation.
The commissioning and startup of the dehumidifier unit must be carried out by professional staff. Otherwise, the
company will not be responsible for all the consequences caused.
Check the installed air filter device to ensure it is in a clean state.
§
Check whether the installation of control components and the connection of control wires are correct
§
Check the configuration and setting parameters of the controller.
§
5.3
Unit
Running
Press the panel shutdown button, the equipment should stop running and the unit returns to the standby
§
state.
Check whether the drainage is smooth and whether the drainage pipe is leaking.
§
Make sure that the dehumidification equipment is connected to the power supply. When the unit is in the
§
standby state, turn on the button on the panel.
Check the installation location of external sensitive components (a representative location for humidity in the
§
controlled area).
5.2.3
Controller
Check
Ensure that the operating voltage of the control unit meets the requirements.
§
After the control unit is powered, it is determined that there is no serious heating phenomenon.
§
Check whether the rotation direction of the fan is correct, the correct rotation direction should be consistent
§
with the direction of the arrow marked on the fan casing
Check whether the vibration of the dehumidifier is normal and whether there is noise inside the equipment.
§
Whether there is a feeling of heat when touching the wires with your hands, please contact the manufacturer
§
to ensure the specifications of the cables used.
Start the dehumidification equipment to run continuously for 10 minutes.
§
Repeat the check every 20 minutes to determine the stability of the dehumidification process.
§
5.5
Performance
Test
Adjust the valve on each air pipe to adjust the air flow according to the design and process requirements.
§
Detect the air moisture content of each return air branch and supply air of the air supply system, and calculate
§
whether the mixing ratio is normal.
5.4
Air
rate
Adjustment
Ensure that the system air volume is rated or other required parameters, and check the equipment technical
§
parameters to determine whether the dehumidification performance is normal.
Record the test results of each status point in the commissioning report.
§
After the air volume is adjusted correctly, lock the air valve in position.
§
Note: The testing instrument must be calibrated. Each test should be separated for a period of time to ensure
accuracy.
