2.0 REAR PANEL CONNECTIONS .
2.1
The DUMP bulkhead connection, Figure 1 (60), is the outlet for air containing
those impurities removed from the unclean feed air. It is vented outside the
instrument cabinet to prevent deposition of water and other materials within the
instrument. The DUMP connection also provides a suitable connection for
sample collection of the impurity concentrate which elutes from this port.
2.2
The DUMP port must NOT be closed or impeded by any restriction which would
produce back pressure at this point.
2.3
The PUMP bulkhead fitting, Figure 1 (58), is a standard ¼-inch swage
connection. Care should be taken that the air supply tubing is kink-free as in
Figure 1.
2.4
The PURE AIR bulkhead connector, Figure 1 (59), is the pure air outlet from the
pure air generator. It will accept ¼-inch swage type connectors.
NOTE: Particulate filters are neither required nor recommended.
2.5
The AUXILIARY POWER outlet, Figure 1, provides power to the compressor
through the PUMP switch, Figure 4 (1).
2.6
Those units supplied for connection to “house” air, as in Figure 3, are shipped
without PUMP switch, fuseholder, and AUXILIARY POWER outlet.
