Dispensing downflow booth installation procedure

1. Back panel installation
The back panel of the dispensing booth is the main part, on which the electrical cabinets, fans, return air plate, etc are installed. The back of the booth must be fixed in a suitable position.

2. Installation of the left and right side panels
The side plate and back plate are connected by bolts. The side plate on each side is composed of 2 plates. After connecting the left and right side panels with the backplate, do not remove the cable tie.

3. Top box installation
Put the top box on the side plate and back plate, and fix the top box and side plate to the back plate with bolts. After the fixing is finished, remove the cable ties on the side plate.

4. Fan for dispensing booth installation
The fan is installed on the square tube above the back plate. It needs to be fixed with damping gasket and extension bolt during installation. Connect the hoses at the back to the air outlets so that air can circulate when the fan is running.

5. Installation of sealing plates
There are three sealing plates on the back panel, on which will be installed respectively the wind speed sensor, differential pressure gauge, DOP test port, control panel, and other devices. It is necessary to install them according to the specific instructions of the manufacturer.

6. HEPA filter and the vent plate installation
HEPA filter of the dispensing booth is installed on the top box. When installing, please pay attention to the airflow direction. When installing the grille, you need to install the aluminum strips before fixing it.

7. Pre-filter and fine filter installation
The RLAF pre-filter and fine filter are installed in the return air inlet and the return air of the dispensing booth is at the bottom. When installing the filter, remember to install the test port and install the return air hole.

8. Curtain installation
Some weighing booths will have an air curtain design, which will blow air down in front of the door to form a curtain to prevent the air inside from spilling out.

If the dispensing booth has a PVC curtain design, we must fix the curtain on the outside of the upper box and fix it with bolts.

9. Inspection and operation
After installing dispensing booth, we need to run a test to check whether it is working properly.
