5.13.2 Housing Assembly
1. The lens support screw is provided to support
the rail assembly. Adjustment will only be
necessary if the rail assembly is rotated at angle
other than horizontal. If the screw head is not
touching the cover when the cover is installed,
loosen the screw until it does. See FIGURE 19.
FIGURE 19 Support Screw Adjustment
2. Replace the cover onto the base assembly by
grasping the cover and gently pushing it over the
end cap and o-ring. Make sure the o-ring is not
pinched. See FIGURE 20
FIGURE 20 Replacing the Cover
3. Align the cover holes with the base assembly
holes and tighten the captive M4 screws. This
secures the cover onto the rest of the housing.
NOTE: Make sure the breather hole is located at the
bottom of the housing. If it is not, remove both front
retaining rings and the face plate. Orient them so the
breather hole is located at the bottom and the gaps in
the retaining rings are centered over the breather hole.
