6. Pump liquid into system until desired pressure is
reached. Allow unit to stabilize for 15-30 seconds.
Pump additional liquid into system until desired pres-
sure is reached.
NOTE! Maximum rated pressure for the Model 1450 is 50
Bar/725 psi. The Model 1450 was designed with a
unique feature to prevent damage to expensive
components in the event of over-pressurizing. The
nylon tube under the cover plate serves as a pres-
sure release and will typically be the first
component to fail if overpressurized. (Figure 7)
7. If system has no leaks the pressure (shown on gauge)
will not drop during test period.
8. Pressure is released by opening the pressure relief
valve.
