3.2.5
Accumulator, Intensifier and MPV Valves, Panel Installation
Tools required:
7/16" open end wrench
Phillips screwdriver
Hex wrench (.061")
Snoop, liquid leak gas detector (PN 64781)
11/32" Open end wrench (thin)
NOTE: See Table 3-2 and Figure 3-2 on page 22 for additional parts info (* denotes reference to Figure 2-1 on page 4).
1. If not already done, remove the panel knobs from the PRESSURE and VENT valves using the .061" hex
wrench.
2. With the panel facing down against the bench, if not already done, remove the five retaining nuts and
lock washers that secure the chassis to the panel. Lift up the chassis enough so that the MPV valves are
able to clear.
3. Install the two mounting screws (PN 60837) from the panel front and tighten until snug.
4. Secure the chassis to the panel with the five nuts and lock washers (tighten until snug).
5. Install the MPV valve knob (15) onto the knob insert (6). Repeat for other MPV valve knob. Align the
set screws (16) with the indentations on the knob insert and tighten until snug using the .061" hex
wrench.
NOTE: To perform the valve adjustments, follow the procedure in Section 3.2.6 and 3.2.7 after completing the following
steps.
6. Using a 7/16" wrench, install the following tubing section that goes from vent port to
MPV
vent
valve
outlet (1/8" dia.).
7. Replace the intensifier and the two clamps.
8. Realign and tighten the fitting nut at the intensifier end of the long 1/4" diameter tubing section that
connects the solenoid valve to the intensifier.
9. Replace the accumulator by sliding in through the clamps.
10. Thread and tighten the six screws that secure the two clamps that hold the intensifier and accumulator.
11. Using a 7/16" wrench, realign and tighten the following tubing sections:
•Pressure valve tee to vent valve tee (1/8" dia.)
•Accumulator to accumulator pressure gauge (1/8" dia.)
•Accumulator to pressure valve fitting (1/8" dia.)
•PIN7010 only: Pressure valve tee to test port fitting (1/8" dia.)
•Vent valve tee to output pressure gauge (1/8" dia.)
•Intensifier assembly to solenoid tee fitting (1/4" dia.)
•Accumulator to intensifier outlet (1/4" dia.)
12. Plug power cord into outlet. Using a pressure source connected to the input port (*4) set input pressure to
100 PSI. Open REGULATOR until REGULATED PRESSURE gauge (*6) rises to 100 PSI. Enable the
POWER
switch (2) and monitor the pressure as it builds in the ACCUMULATOR PRESSURE gauge
(*2). Turn the
POWER
switch (*2) off when 1,000 PSI has been achieved. Check all fittings for leaks. If
there are no leaks vent system and remove pressure source.
NOTE: See Section 2.2 on page 3 for pressure source connection procedure.
13. Install panel/chassis assembly in its enclosure as described in Section 3.2.1 on page 6.
3.2.6
MPV Pressure Valve, Adjustment Procedure
Tools required:
Hex wrench (.050")
Hex wrench (.061")
NOTE: See Table 3-2 and Figure 3-2 on page 22 for additional parts information (* denotes reference to Figure 2-1 on
page 4).
1. Turn the supply pressure regulator off.
2. If not already done, remove the valve knob (15) using the .061" hex wrench.
3. Verify the power cord is plugged in.
4. Using a .050" hex wrench, loosen the set screw (13) on the MPV valve locknut (12) and turn the locknut
clockwise to its stop.
