To connect the nitrogen exhaust line:
Warning:
carried in the nitrogen exhaust, ensure that the nitrogen exhaust
is vented via the nitrogen exhaust trap bottle and laboratory
exhaust system. The laboratory exhaust system must provide a
minimum vacuum of 0.20 kPa (2 mbar, 0.03 psi) below
atmospheric pressure (negative pressure).
Warning:
hazardous, or toxic materials, and to avoid spreading
contamination to uncontaminated surfaces, wear clean,
chemical-resistant, powder-free gloves when working with the
exhaust connections.
Warning:
nitrogen exhaust trap bottle in an enclosed cabinet.
Notice:
separate exhaust systems are required: one for nitrogen, the other
for the roughing pump. Vent the exhausts to atmosphere through
separate exhaust lines. Oil mist can seriously damage the
instrument if the nitrogen exhaust line connects with the roughing
pump exhaust line. Your warranty does not cover damage caused
by routing exhaust lines incorrectly.
1. Locate the exhaust trap bottle in an accessible area below the
instrument (see the figure on
2. Cut a length of 12-mm tubing long enough to connect the instrument to
the exhaust trap bottle.
Requirement:
horizontal axis).
3. Connect one end of the tubing to the exhaust port on the rear panel and
the other end to one of two ports on the exhaust trap bottle.
4. Cut a length of 10-mm tubing long enough to connect the exhaust trap
bottle to the exhaust vent.
5. Insert one end of the tubing into the remaining port on the exhaust trap
bottle and route the other end to the exhaust vent.
