Installation steps and precautions for the automatic double-door air shower

I. Preparations before installation
Site confirmation and planning
Check whether the spatial dimensions (length, width, and height) of the installation location match the specifications of the material shower room, and reserve sufficient operation and maintenance space (it is recommended to reserve 50-100cm around).
Confirm the flatness of the ground, with an error not exceeding ±5mm. A level can be used for detection. If necessary, level it with cement or shims.
Ensure that there is a stable power supply (usually 380V three-phase five-wire or 220V single-phase, and the equipment power needs to be confirmed in advance) and grounding device (grounding resistance ≤4Ω) near the installation area.
Equipment inventory and inspection
After opening the box, check against the list to see if all the accessories are complete (such as the main box body, double door assembly, fan, filter, control system, sealing strip, etc.).
Check whether there are any bumps or deformations on the surface of the equipment, whether the door body glass is intact, and whether the electrical components are loose.
Ii. Detailed Installation Steps
Positioning and fixing of the main box body
Move the main box of the goods air shower to the installation position, and use a level to adjust the levelness of the box (the deviation between the horizontal and vertical directions is ≤2mm) to avoid tilting that may affect the opening and closing of the door and the uniformity of the airflow.
Fix the bottom of the box to the ground with expansion bolts to ensure stability and prevent vibration during operation.
2. Installation of double door assembly
Install the left and right door frames. Make sure the sealing strips between the door frames and the box body fit tightly to prevent air leakage.
Fix the door body glass and ensure that the connection between the glass and the door frame is sealed (silicone sealant can be used) to prevent dust from seeping in.
Install the automatic door drive device (such as motor, track, sensor), adjust the opening and closing speed and sensitivity of the door body, and ensure that the interlocking function of the two doors is normal (when one side door is opened, the other side door is automatically locked).
3. Installation of fans and filters
Fix the fan at the designated position on the top or side of the box, and connect shock absorption devices (such as shock absorption pads) to reduce operating noise.
Install a high-efficiency air filter (HEPA or ULPA), and pay attention to the sealing between the filter and the frame (sealant or pressing device can be used) to avoid bypassing unfiltered air.
The air duct connecting the fan and the filter should be ensured to be sealed without leakage. This can be checked by visual inspection or smoke test.
4. Electrical system connection
Connect the control mainboard, power supply, fan, sensors (such as infrared sensor switches), and indicator lights according to the circuit diagram.
Install leakage protection devices and overload protection devices to ensure electrical safety.
Test the functions of the control system, including whether the logic of the door body switch, the start and stop of the fan, and the timing functions (such as the setting of the spray-blowing time) are normal.
5. Installation of sprinkler system (if any)
If the goods shower room includes a spray function, water pipes, nozzles, and solenoid valves need to be installed to ensure that there is no leakage in the water connection.
Debug the sprinkler program to coordinate with the fan and door body actions (such as automatically starting the sprinkler after the door is closed).
6. Sealing and cleaning
Fill the joints of the box body and the edges of the door frame with sealant to prevent dust from entering.
After installation is completed, thoroughly clean the interior of the equipment to remove debris, oil stains, and other impurities generated during the installation process.
Iii. Installation Precautions
Safety operation specifications
Be sure to cut off the power during the installation process to avoid the risk of electric shock. When working at heights, use safety ropes to ensure personnel safety.
When moving the equipment, use special tools to avoid deformation of the box or damage to the accessories.
2. Environmental and precision requirements
The installation environment temperature should be between 5 and 40℃, and the humidity should be no more than 85% RH to prevent electrical component failures caused by damp conditions.
The installation of the fan and the filter must be kept vertical to prevent the airflow from being skewed and affecting the blowing effect.
3. Key points of functional testing
Door interlock test: When one side door is opened, the other side door should not be able to be opened to prevent air convection between the clean area and the non-clean area.
Wind speed test: Use an anemometer to measure the wind speed at the air outlet (usually ≥25m/s) to ensure that the blowing effect meets the standards.
Noise test: The noise during operation should be ≤ 75 dB. If the noise is too loud, it is necessary to check the fan's fixation or vibration reduction measures.
4. Compliance and Certification
The installation should comply with the relevant standards of cleanrooms (such as ISO 14644, GMP, etc.). If necessary, a third-party institution should be invited to test the cleanliness level.
Electrical installation must comply with local electrician standards, and the grounding system must be reliable.
5. Reserve for later maintenance
Reserve inspection ports (such as filter replacement ports and fan maintenance doors) to facilitate later maintenance.
Record the installation parameters (such as fan power, filter model, and control program Settings) for reference in subsequent maintenance.
Iv. Acceptance Criteria After Installation
The equipment operates smoothly without abnormal vibration or noise.
The automatic door opens and closes sensitively, the interlock function is reliable, and the control of the shower time is accurate.
The internal cleanliness of the box meets the design requirements (such as ISO level 7 or higher), and the number of dust particles complies with industry standards.

By following the above steps and taking precautions, the installation quality of the automatic double-door cargo shower can be ensured, enabling it to effectively purify goods and isolate contamination. If you lack professional installation experience, it is recommended to contact the manufacturer or a professional team for construction to avoid affecting the performance of the equipment due to improper installation.
