5.2.5 Replacing the Maintenance Cover
The following is the recommended procedure to set the maintenance cover in place and the correct
pattern for tightening the screws to maintain proper weather proofing.
Note: Verify that the gasket is “seated” fully within the groove encircling the opening before setting
the cover in place.
1. Carefully place the maintenance cover (utilize the location pin) over the opening and hand
tighten the six (6) M4 screws in place.
Caution: Replace the maintenance cover in the exact same orientation as it was when removed
with the ridges on the cover aligning with the ridge pattern on the unit, as shown below.
2. Tighten the screws in the following pattern in order to achieve proper pressure for optimal
weather proofing.
Figure 17: Screw Tightening Pattern
Tightening the screw in this pattern reduces the likelihood of the cover shifting and flexing, which could
nullify the weather proofing.
When you’ve tightened all the screws, go back through the pattern again with the torque screwdriver to
ensure that every screw is tightened appropriately.
Caution: Initially hand-tighten the six (6) M4x20 captive screws. Torque the screws to no more
than a maximum of 8.0 in-lbs or 0.9 Nm using a Torque screwdriver.
