1. Vent any remaining gas from the system to atmosphere. Disconnect the power cord from the power
source.
2. Remove front panel from its enclosure as described in Section 4.2.1 on page 16, and carefully place on a
bench top.
3. Remove regulator knob cap and two screws that secure the round plate.
4. Loosen and remove the locknut using a 1/2" socket while holding the knob. Remove the knob by turning
counter-clockwise.
5. (UPC5210 Only) Loosen tube nut on INPUT PORT fitting. Remove the two screws and
POWER/INPUT PORT panel.

4.2.12 Regulator (Standard Pneumatic) and Solenoid Installation
Solenoid 120 VAC input - PN 56851, Solenoid 220 VAC input - PN 54366
Tools required:
Phillips screwdriver
7/16" open end wrench
9/16 " open end wrench
A/R 1/4" wide teflon tape, (PN's 60575)
A/R 1/2" wide teflon tape, (PN's 60911)
snoop, liquid leak gas detector (PN 64781)
1/2" socket
socket wrench
1. Wrap two layers of teflon tape on the pipe threads of each fitting and install into the inlet and outlet of the
regulator and ensure that each, as well as, solenoids are oriented properly. Use a bench vise when doing
this.
2. Insert the new regulator/solenoid assembly into the panel through hole. Pass the adjusting end through
the mounting ring. Do not tighten cap screw until adjusting knob is installed.
3. Install the tubing sections to the inlet and outlet fittings.
(UPC5210 only) Replace the POWER/INPUT PORT panel and 2 mounting screws. Thread and tighten
tube nut on INPUT PORT fitting.
4. Install the adjusting knob on the threaded shaft by turning clockwise. Turn adjusting knob on threaded
shaft until bottomed and install locking nut and tighten. Turn knob until it bottoms. Position the regulator
so that the bottom of the knob is 1/2" from the panel surface, then tighten the cap screw on the
mounting collar.
5. Using a pressure source connected to the input port (4) set regulated pressure to 100 PSI. Enable the
PUMP CONTROL switch (20) and monitor the pressure as it builds in the ACCUMULATOR gauge (9).
Turn the PUMP CONTROL switch (20) off when 1,000 PSI has been achieved. Check all fittings for
leaks. If there are no leaks vent system and remove pressure source.
6. Install panel/chassis assembly in its enclosure as described in Section 4.2.1 on page 16.
