Camera Window Replacement - PTZ70

CAUTION!
Before performing any maintenance task, be sure to de-pressurize the camera unit via the
Schrader valve (see page 12).
To replace the camera window, follow these steps:
• Remove the four Phillips screw from the front of the camera housing (fig. 59).
• Using a pointed object, such as a pick, gently pry the o-ring loose from the outer edge of the
window that needs to be replaced. The window will come loose with the o-ring (fig. 65).
• Lubricate new o-ring with silicone lube. It should appear slightly oiled with no excess grease.
Place new window in exposed opening and place new o-ring around it. When the disk tight-
ens, the o-ring will move into place.
• Replace front disk making sure the four small o-rings are in place (fig. 66).
• Tighten front ring until it is flush with housing. Loctite 243 is recommended for these screws.
• Pressure test camera housing. See "Pressure Testing" section on page 82.
