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 air flow is in the direction of arrow.
Installation must be upstream of and 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.
Operation
1.
BEFORE TURNING ON AIR SUPPLY, TURN ADJUSTING
HANDLE COUNTERCLOCKWISE UNTIL COMPRESSION
IS RELEASED FROM PRESSURE CONTROL SPRING. Then
turn on air supply and adjust regulator to desired secondary
pressure by turning adjusting handle clockwise. This permits
pressure to build up slowly, preventing any unexpected
operation of the valve, cylinders, tools, etc., attached to the
line. Adjustment to desired secondary pressure can be made
only with primary pressure applied to the regulator.
2.
To decrease regulator pressure setting, always reset from a
pressure lower than the final setting desired. For example,
lowering the secondary pressure from 550 to 410 kPa
(80 to 60 PSIG) is best accomplished by dropping the
secondary pressure to 350 kPa (50 PSIG), then adjusting
upward to 410 kPa (60 PSIG).
Use the hex nut, located on the adjusting screw, to lock the
pressure setting.
