WARNING
❑
Be sure power is disconnected from the leak detector before
attempting to replace the top cover. The start button could be
pressed while maneuvering the cover into place and the leak
detector inadvertently started.
❑
Take care not to catch any wires when replacing the cover.
❑
Be sure the start and stop buttons have smooth, normal
motion and that they are not constrained by the top cover.
To replace the top panel:
1. Place the top cover onto the frame, fitting it around the front of the chassis, the start and
stop button panel, the test port, and the upper back of the turret.
2. Working at the rear of the leak detector, place the two 3-8 nuts onto the screws located
in the back corners under the upper frame and tighten them fully.
3. Working from the front of the leak detector, replace the three 5-16 nuts under the front
edge of the top cover.
4. If it was removed, replace the service pendant shelf using the procedure described in
“Replacing the Service Pendant Shelf” on page B-4.
5. Replace the upper rear panel.
NOTE
While the test port is extracted, i examine it to see if it requires
cleaning. See “Examining and Cleaning the Test Port” on
page 4-34.
