B-10 External Connections
.
1. Place the pump on the floor, within 1.5 m (5 feet) of the instrument.
2. Attach the NW25/NW40 adaptor to the roughing pump inlet flange
using an NW40 center ring, and then secure the connection with an
NW40 clamp, using the 7-mm nut driver to install the clamp.
3. Attach the NW25 tee to the NW25/NW40 adaptor using an NW25 center
ring, and then secure the connection with an NW25 clamp, using the
7-mm nut driver to install the clamp.
4. Using the NW25 center rings and clamp, and the 7-mm nut driver,
attach the flanged end of a length of 1-inch ID vacuum hose to the top
port on the NW25 tee, and the 10-mm reducer fitting and a length of
10-mm ID nylon tubing to the middle (perpendicular) port on the tee.
5. Using 2 hose clamps, connect the opposite end of the length of 1-inch
vacuum hose in step 4 to the 1-inch OD straight vacuum port on the
instrument’s rear panel.
6. Connect the opposite end of the 10-mm nylon tube to the 10-mm source
vent port on the instrument’s rear panel.
7. Using 1 hose clamp, connect a length of 12.7-mm clear PVC exhaust
tubing to the roughing pump exhaust port NW25 nozzle fitting.
8. Route the open end of the exhaust tubing to a suitable exhaust vent.
9. Make the electrical connections to the roughing pump (see page B-11 ).
Warning:
The roughing pump is heavy. To avoid injury, at least
two people must lift the pump.
Caution:
To avoid gas leaks, use the sharp knife to cut the PVC
exhaust tubing squarely (that is, perpendicular to its horizontal
axis).
Caution:
The instrument requires two separate exhaust systems:
one for nitrogen, the other for the roughing pump. Vent them to
atmosphere through separate exhaust lines. Your warranty does
not cover damage caused by routing exhaust lines incorrectly.
