Installation of air switch distribution box in building

To install an air switch in a distribution box, mount the switch securely, connect the air tube, and wire the switch to the appropriate circuit while ensuring proper insulation and safety.

Preparation and Placement

1. Select the distribution box: Ensure it is intact, dry, and ventilated. Both metal and plastic boxes are suitable, but the installation pedestal must be clean and unobstructed for easy access .
2. Positioning: Install the box at a convenient height, typically around 1.8 meters for easy operation . Ensure the box is vertical and horizontal, leaving a 5–6 mm gap if embedded in a wall .
3. Space for the air switch: The pedestal should have enough space for the air switch and its air tube, avoiding any obstruction .

Mounting the Air Switch

1. Drill the mounting hole: Use a Ø1.25” hole (or as specified by the model) at the chosen location .
2. Insert the transmitter: Remove the mounting nut, insert the air switch body through the hole, and secure it with the nut .
3. Attach the air tube: Connect one end of the air tube to the switch and route it safely to the controller or pressure-sensitive switch inside the distribution box . Ensure the tube is unobstructed and not kinked.

Electrical Connection

1. Power off: Switch off the main AC supply before wiring .
2. Connect to the circuit: Plug the device to be controlled into the air switch socket. For 220–240V systems, ensure the plug and socket match the local standard .
3. Grounding: Confirm that the distribution box and the air switch are properly grounded .
4. Secure wiring: Ensure all wires are long enough, neatly arranged, and terminal screws are tightened. Separate live, neutral, and earth lines on the bus bar .

Testing

1. Power on: Restore AC power to the distribution box.
2. Operate the switch: Press and release the air switch button to verify that the connected device turns on and off correctly .
3. Troubleshooting: If the device does not operate, check the power supply, fuse, air tube for obstructions, and the switch button for smooth operation .

Safety Tips

• Avoid rapid cycling of the air switch to prevent damage .
• Keep the distribution box clean and free of debris after installation .
• Ensure all connections are insulated and comply with local electrical codes . Following these steps ensures a safe, functional, and durable installation of an air switch in a distribution box.
