ASSEMBLY
1. Using the 3/4" open-end wrench, remove the brass end plug from the existing Dixon Bayco Air
interlock valve. Hold the end plug firmly to prevent the spring from ejecting the plug from your
hand.
2. Leave the main spring installed inside the plunger. You may discard the brass end plug.
3. Install the new brass end plug from the kit. This is accomplished by compressing the main
spring while tightening the new end plug in place.
4. From the kit bag, place the small compression spring through the hole in the new brass end
plug until it slides down the inside of the main spring.
5. From the kit bag, place the pin through the hole in the new brass end plug until it slide s down
the inside of the main spring.
6. Retrieve the limit switch from the kit bag. Insure that the two lock nuts are installed and are
threaded against the body.
7. Install the limit switch into the new brass end plug as far as it will go. Do not over tighten.
8. You can back the limit switch off a maximum of 1/2 turn to orient the switch the way you like it.
9. Secure the switch by tightening one of the jam nuts (using the 14mm wrench) against the brass
end plug.
10. Connect the wire cable to the limit switch by aligning the notch in the wire plug to the projection
in the limit switch. Tighten the collar of the wire cable to secure it to the limit switch
11. Connect the brown and white wires of the cable to the AUX port of the on board monitor.
