5977B Series MSD Troubleshooting and Maintenance Manual 123
To Install the DP
Materials needed
• Gloves, oil-resistant
• Vacuum cleaner, non-ESD generating (92175V or equivalent)
This procedure works best with two people, one to hold the pump, and one to
install the clamp.
Procedure
1 Vacuum the fan that cools the DP.
Keeping the fan clean helps ensure maximum cooling. This is one of the
few times you will have convenient access to the pump side of the fan.
2 Slide the DP into the MSD.
You may have to tilt the pump slightly to get it into the MSD. Do not tilt it
past 45 degrees.
3 Install the O-ring assembly on the DP. (See Figure 16 on page 124.)
4 Lift the DP into its normal position.
5 Install the KF50 clamp.
6 Reconnect the DP temperature sensor wires to the wiring harness.
7 Reconnect the high vacuum power cable to the HIVAC POWER connector
on the back panel of the MSD. This is the thick black cable that emerges
near the bottom of the pump.
8 Reconnect the foreline gauge fitting to the outlet of the DP.
If you disconnected the foreline gauge cable, reconnect it to the foreline
gauge.
9 Move the MSD back to its normal position.
