Step-by-Step Installation

1. Choose the Location Select a convenient spot on your stainless steel distribution box or countertop where the air switch button will be accessible. Ensure there is enough clearance underneath for the lock nut and tubing ( ). 2. Drill the Hole

• Drill a hole of 1 3/8 inches (35 mm) for most stainless steel air switch buttons ( ).
• For some models, a 1 1/2-inch hole may be required if using a larger button or top-mount sink deck ( ).
• Ensure the edges are smooth to prevent damage to the O-ring or tubing. 3. Insert the Air Switch Button
• Loosen the switch base to expose the threads.
• Insert the button through the drilled hole.
• Slide the washer up and thread the clamp nut onto the threaded shroud underneath the box or countertop.

• Connect the other end to the tube fitting on the power control box ( ).
• Ensure the tubing is free of kinks or obstructions to allow proper air pulse transmission ( ). 5. Plug in the Power Module
• Plug the power control box into a grounded electrical outlet under the sink or distribution box.
• Plug your garbage disposal or appliance into the power module.
• Make sure the AC power point matches the voltage and rating of the air switch unit ( ). 6. Test the Air Switch
• Turn on the AC power.
• Press the stainless steel button to verify that the disposal or appliance turns on and off correctly.
• If it does not work, check the power supply, fuse, and tubing for obstructions ( ). 7. Optional Adjustments
• Some models allow changing the button color or trim by removing the outer ring from the bellows body ( ).
• Ensure the button is vertically aligned and securely fastened for a clean, professional look ( ).

Safety Tips

• Always turn off the power at the outlet before installation.
• Use a grounded outlet to prevent electrical hazards.
• Avoid placing the switch near water without proper sealing.
• Confirm that the disposal or appliance is compatible with the air switch's power rating ( ). Following these steps ensures a safe, code-compliant, and aesthetically pleasing installation of a stainless steel air switch in your distribution box.
