Attaching the Pump
If you are performing a conversion of a D16A pump to a D16B, you must
obtain more detailed conversion instructions from the ASPS Help Desk.
1. Block 2: If you have removed the pump tray, reattach it with the 17
mm bolts. Attach the vacuum pump to the sump plate (Block 2 or
place it on the tray). Lightly secure the nut plate straps.
2. If it has been removed, attach the drain valve to the pump. (New
pumps are usually shipped with the drain valve assembly already
installed.)
3. Open the gas ballast valve. Attach the oil drain tube to the vacuum
pump oil drain ball valve. Fasten the tube with a hose clamp. Attach
the tubing to the frame.
Replace the HEPA filter
4. Attach the HEPA filter.
Replace the Intake Filter
5. Install the filter outlet flag on the side of the pump marked IN. (If you
are performing an A to B conversion, the removed flange is a KF-40
and the installed flange is a KF-25.) Tighten the flange using a
KF-25 clamp.
6. Attach the pump intake filter assembly to the elbow with the housing
on the right side of the machine (viewed from the rear) and secure
with the centering ring and clamp. Verify that the flow arrow on the
filter body points away from the pump and the IN port connects to
the elbow.
Replace the Throttle Valve
7. Attach the throttle valve assembly to the OUT side of the intake filter
assembly.
8. Verify that the valve actuator is vertical and the intake filter side is
on the HI VAC side of the pump.
9. Attach the elbow to the chamber port. Align the elbow to the throttle
valve.
