2.0 Operation
The following sections explain the various procedures for operating the UPC5100/UPC5110.
2.1 Pressure Cylinder Filling Procedure
To initially fill or refill the internal pressure cylinder (2015 PSI max) of the UPC5100/UPC5110, see Figure 2-1
and proceed by following these steps:
NOTE: Check the Nitrogen Fill Port markings on Pressure Console, some units may be 2216 PSI max.
1. Close PRESSURE LIMIT CONTROL (1) by pulling regulator knob outward and turning
counter-clockwise. When closed, push knob inward. Close the COARSE ADJUSTMENT valve (2) by
rotating clockwise until it stops.
2. Connect the fill hose (3), to a clean regulated nitrogen source (5).
3. Connect the other end of the fill hose (3) to the male fill port fitting (4).
4. Slowly open the valve on the nitrogen source and allow the gas to flow into the pressure cylinder. The
SUPPLY PRESSURE gauge (6) indicates the amount of pressure within the internal cylinder.
NOTE: The Inlet Check Valve (PN 60263) and the Nitrogen Fill Port (Section 4.2.17 on page 32; Figure 4-4 on page 41)
can be damaged if pressure is released too fast.
5. Use the following procedure for filling the cylinder:
a) Fill cylinder to 1000 PSI at a rate of charge equal to a minimum of two minutes, then wait five
minutes for system to stabilize.
b) Fill cylinder from 1000 PSI to maximum pressure at a rate of charge equal to a minimum of two
minutes.
c) Wait five minutes for system to stabilize before using.
