4.2 INLET ADAPTER MOUNTING
Various Inlet Adapters can be used for 4.5” Quick Connect Monitors and Elbows. These Inlet Adapters must be oriented upon installation
for the monitor to point in the desired direction. Figure 4.2 shows examples of Inlet Adapters and the location of a “Straight Ahead
Reference Mark” recessed into the threads. In the case of the VUM, the hex head trunnion between ports C2 and C3 serves as the
Straight Ahead Reference Mark.
Travel ranges relative to the Straight Ahead Reference Mark can be modified by using Stop Bolts, which are used to limit the travel. See
instruction manual for monitor for use of Stop Bolts.
