light and live electrical components. There is a risk of serious injury to skin and eyes from UV light.
There is a risk of shock, injury, and /or death from contact with live electrical components.
Personal Protective Equipment
1. Eye protection that prevents 100% of UV light being transmitted through the lens must be worn at all
times when working on UV Lamp Modules on any CG3-UVi-SPC Ventilator that is energized and/or
has the potential to be energized and expose personnel to UV light.
2. Whenever service work is performed it is recommended that long sleeve shirts and pants be worn to
minimize the potential for inadvertent exposure of the skin to UV light.
Instructions for Replacing UV Lamp Sockets
To replace UV Lamp Sockets carefully use the following step by step instructions.
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).
5.
Remove the eight nuts that hold the Module in place.
6.
Carefully slide out the UV Module and place on a work bench.
7.
Next, remove the Module End Caps from each end of the Module. Using a box or open end wrench,
hold the End Cap Nut on the back side of the end (Refer to Figure 6-9-3) while backing out the End
Cap Bolt from the front side of the End Cap (Refer to Figure 6-9-4). There is a retainer washer on the
back side of the End Cap that prevents the bolt from sliding out of the End Cap.

The sockets, with wires, that slide onto the ends of the UV Lamps are called UV Lamp Sockets (Refer
to Figure 6-10-1). The wires are marked from the Factory with a number 1 through 6 for the left end
and 7 through 12 for the right end (Refer to Figure 6-10-2 and 6-11-1).
