Wilkerson P12 - Manual

Introduction:
Follow these instructions when installing, operating, or servicing
the product.
Application Limits
These products are intended for use in general purpose
compressed air systems only.

Maximum Inlet Pressure 1734 250 17.3
Ambient Temperature Range: 0°C to 80°C (32°F to 175°F)
ANSI Symbols
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.). 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, turn the adjusting knob
counterclockwise until compression is released from the
control spring. 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.
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). Push the adjusting knob down to lock
the pressure setting.
WARNING
To avoid unpredictable system behavior that can cause personal
injury 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
tested for proper function and leakage. If audible leakage is
present, or the product does not operate properly, do not put
into use.
• Warnings and specifications on the product should not be
covered by paint, etc. If masking is not possible, contact your
local representative for replacement labels.
