Replacing UV Module Plate Gasket
Overview
A deteriorating UV Module Plate Gasket will allow water to leak into the UV Module Electrical Raceway
and cause the UV Module and other electrical components to fail. Carefully inspect the UV Module Plate
Gasket for cracks or deterioration (Refer to Figure 6-41-1). Replace as needed to ensure a good seal.
Instructions for Replacing UV Module Plate Gasket
1. Turn off all power to the Gaylord Command Center.
2. Turn off all circuits that supply power to the UV Lamps.
3. Open the UV Module Access Door.
4. Disconnect the Lamp / Ballast Connector plug (Refer to Figure 6-9-1 and 6-9-2).

Explanatory Note: The replacement gasket comes as one piece with punched holes for going
over the treaded weld studs. The gasket has a peel off sticky back.
9. Starting at one end peel back about 4" of the Mylar protective cover, to expose the sticky surface,
and place the gasket over the first threaded studs and apply to the stainless surface.
10. Continue peeling off the back and apply the gasket as you continue. As you apply be sure to keep
the gasket straight.
11. Once the entire gasket is in place, run your finger or a smooth dull object along the gasket,
pushing to insure a good bond.

inch - lbs.
