2.0 Operation
The following sections explains the various procedures for operating the UPC5000/UPC5010.
2.1 Pressure Cylinder Filling Procedure
To initially fill or refill the internal pressure cylinder (2216 PSI max) of the UPC5000/UPC5010, see Figure 2-1
and proceed by following these steps:
1. Rotate the PRESSURE LIMIT CONTROL (1) counter-clockwise until it stops. 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 4.2.19 on page 25; Figure 4-3 on page 35)
can be damaged if pressure is released too fast.
5. Use the following procedure for filling the cylinder:
a) Fill cylinder to 1,000 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 1,000 PSI to 2,216 PSI at a rate of charge equal to a minimum of two minutes.
c) Wait five minutes for system to stabilize before using.
