Installation
1. The regulator should be installed with reasonable
accessibility for service whenever possible - repair service
kits are available. Keep pipe and tubing lengths to a minimum
with inside clean and free of dirt and chips. Pipe joint
compound should be used sparingly and applied only to
the male pipe - never into the female port. Do not use PTFE
tape to seal pipe joints - pieces have a tendency to break
off and lodge inside unit, possibly causing malfunction.
2. Install regulator so that media flow is in the direction of
arrow. Installation must be upstream (high pressure) side
and as close to the devices it is to service (valve, cylinder,
tool, etc.). Mounting may be in any position.
3. Gauge ports are located on both sides of the regulator
body for your convenience. It is necessary to install a
gauge or pipe plugs into each port during installation.
4. For protection against rust, pipe scale, and other foreign
matter, install a filter on the upstream (high pressure) side
as close to the regulator as possible.
Reduced Pressure Adjustment
To adjust reduced pressure settings, loosen lock screw in center
of knob and turn knob clockwise to increase pressure setting,
and counterclockwise to lower setting. With relieving-type
regulators, the reduced pressure follows adjustment of the screw.
With non-relieving regulators, adjustment for lower reduced
pressure will not be obtained until the reduced pressure system
is “bled off” or until air flow starts.
WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.

Inspect for nicks, scratches, and surface imperfections. If present,
reduced service life is probable and future replacement should
be planned.

Service
Caution: Disconnect or shut off air supply and exhaust
the primary and secondary pressures before servicing
unit. Turning the Adjusting Knob counterclockwise does
not vent downstream pressure on non-relieving
regulators. Downstream pressure must be vented before
servicing regulator.
Caution: Grease packets are supplied with kits for
lubrication of seals. Use only mineral based grease or
oils. Do not use synthetic oils such as esters. Do not use
silicones.
Note: After servicing unit, turn on air supply and adjust regulator
to the desired downstream pressure. Check unit for leaks. If
leakage occurs, do not operate - conduct repairs and retest.
Cleaning
Erratic regulator operation or loss of regulation is most always
due to dirt in the disc area. To clean, shut off and depressurize
air line, and disassemble the regulator. Refer to drawing as a
guide to disassembly and subsequent reassembly. Clean parts
with household soap and blow out body with compressed air.
When reassembling, make sure the disc assembly is firmly in
place, and that the disc stem fits into center hole of diaphragm
assembly. Tighten cage slightly more than hand tight (to 50
inch pounds torque).
