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.
Operation
1. Before turning on the media source, disengage the Adjusting
Knob by pulling upward. Turn the Adjusting Knob
counterclockwise until compression is released from the
Control Spring. Then turn on media source 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.
Reduced Pressure Spring Ranges
“A” Range = 0 – 25 PSI
“B” Range = 0 – 60 PSI
“C” Range = 0 – 125 PSI
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 media source and depressurize all media 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, media 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.
