•
Source air supply (A1): facility air supply to power
SPU.
•
Air motor drive air (A2): air supply to drive pump
air motor.
•
Main air slider valve (BA): turns air on and off to
the system. When closed, the valve relieves pres-
sure downstream.
•
Ram air regulator (BB): controls ram up and down
pressure and blowoff pressure.
•
Ram air pressure gauge (BC): displays the air
pressure used to raise and lower the ram.
•
Ram director valve (BD): controls ram direction.
•
Air motor regulator (BE): controls air pressure to
motor.
•
Air motor pressure gauge (BF): displays the air
pressure used to drive the air motor.
•
Blowoff button (BG): turns air on and off to push
the platen out of an empty pail.
•
Air motor slider valve (BH): turns air on and off to
the air motor. When closed, the valve relieves air
trapped between it and the air motor. Push the valve
in to shutoff.
•
Air motor safety relief valve (BI): prevents over-
pressurization of air motor air supply.
Replace Director Valve
Numbers in parentheses refer to F
1.
Disassemble the air control. See Disassembly,
page 4.
2.
Remove screws (4a) and take off director valve.
3.
Remove spring (4c), valve plate (4d), and o-ring
(4b)
.
4.
Remove and discard pin (4g) and four valve seats
(4e) with o-rings (4f).
5.
Insert new valve seats (4e) with o-rings (4f) and new
pin.
6.
Insert new director valve plate (4d, see Note above)
spring (4c), and o-ring (4b).
7.
Attach new director valve with screws (4a). Tighten
screws until snug.
Replace Air Motor Regulator
Numbers in parentheses refer to Parts, page 7.
1.
Disassemble the air control. See Disassembly,
page 4.
2.
Disconnect air motor hosing and fittings.
3.
Remove two screws (9a) and take off the shutoff
valve (3) at top of module. If your supply system has
an air solenoid, it can remain attached to the shutoff
valve.
4.
Remove two screws (9b) and take off the air motor
regulator (6).
5.
Attach new regulator to manifold. Orient so the
gauge lines up with the gauge on the ram air regula-
tor and the direction of flow arrow points up. Tighten
screws until snug. Recommend using thread locker
Loctite 220 or equivalent.
6.
Reattach shutoff valve (3) at top of regulator. Make
sure that o-ring (5) is in place on valve (3).
Note the orientation of the director valve plate when
you remove it. The opening should be on the oppo-
site side (left) of the lever.
