Backup vacuum pump
Turn off the main power switch. You need the service kit for the Gas vacuum pump. If
the kit includes instructions with diagrams, do not use them. Instead, refer to
Figure
80
and
Table 5
and use the following procedure:
1.
1. Let the pump cool until it is no longer too hot to handle.
2.
Disconnect the inlet and outlet sample tubes from the pump, noting the location
of each tube so that they are reconnected to the correct fitting.
3.
Remove the bolts on the pump plate (below the pump).
4.
Slide out the pump to the front of the cabinet. Then, lift it and rotate it so that the
pump head is facing you with the motor to the rear.
NOTE
Expect a release of carbon dust when this pump is disassembled. If this might
create a problem where the ACM 150 monitor is installed, disconnect the power
cord and move the pump to an acceptable work area before continuing.
5.
Remove the two End Caps and their O-Rings.
6.
Remove the 5 bolts on the Muffler Box and tap it lightly with a small hammer to
break it loose.
7.
Scrape off the Gasket between the Muffler Box and the End Plate.
8.
Remove the 6 bolts that hold the End Plate to the Body.
9.
Remove the End Plate and the 4 Vanes.
10.
Use steel wool to clean dirt and dust made by the old Vanes off of surfaces.
11.
Install the 4 new Vanes from the kit so that the beveled end slides into the slots in
the same orientation as the old vanes.
12.
Hold the End Plate to the Body and install the 6 bolts using a torque sequence.
13.
Install a new Gasket from the kit between the End Plate and Muffler Box.
14.
Get 5 new Bolt Gaskets from the kit and replace the old ones before bolting the
Muffler Box to the End Plate. Screw in the bolts but leave them loose.
15.
Using the 2 new O-Rings from the kit screw in and tighten both End Caps. Throw
away the Felt Filters in the kit. No filters are used in the ACM 150 monitor pump.
16.
Tighten the bolts attaching the Muffler Box to the End Plate.
17.
Restore power and restart it while the pump is still pulled out. Assure that you
have a strong suction and that there are no irregular noises or other problems.
18.
Slide the pump back in place and reconnect the tubes and pump plate bolts.
