and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the product

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 (high pressure) side and as
close to the devices it is to service (valve, cylinder, tool,
etc.) as possible. 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 the air supply:
1A. On PR364, disengage the adjusting knob by pulling upward.
Turn adjusting knob counterclockwise until the compression
is released from the pressure control spring.
1B. On PR10, push down on the adjusting knob while turning
knob counterclockwise until the compression is released
from the pressure control spring. (Knob is locked when
up.)
2. Then turn on air supply and adjust regulator to desired
secondary pressure by turning adjusting knob 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.
3.
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).

WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.
