2. Turn on the supply air pressure and then turn the adjusting
knob clockwise until the desired secondary pressure is
reached.

3. To avoid minor readjustment after making a change in
pressure setting, always approach the desired pressure
from a lower pressure.

4. When reducing from a higher to a lower setting, first
reduce to some pressure less than that desired and then
increase to the desired pressure.

Maintenance

1. The regulator can be disassembled for servicing without
removal from line.

2. Occasionally remove bottom plug and clean plug, body and
valve seat.

3. TO DISASSEMBLE — shut off air to regulator and vent air
line on both sides of regulator. Turn adjusting knob
counterclockwise to relieve compression on spring.
Remove the knob cover cap, screws, cover and spring.
Diaphragm assembly can now be removed. By removing
bottom plug and spring the valve stem can be removed
from the bottom of the regulator.

4.

IF UNIT WILL NOT REGULATE TO DESIRED PRESSURE

or if pressure becomes excessive - remove bottom plug,
spring, and valve assembly. Clean all parts and check valve
seat for wear or damage. Replace worn or damaged parts.

5. If excessive air leaks continuously from relief hole, the
regulator should be taken out of service and a
recommended repair kit installed, as listed under Repair
Kits and Replacement Parts.

6. WHEN REPLACING DIAPHRAGM ASSEMBLY — The
PRP-95-960 diaphragm assembly is a relieving-type
diaphragm.

Installation

1. Install the Regulator as close as possible to the application.

2. Install the unit with the air flowing through the body in the
direction indicated by the arrow.

3. Gauge ports (1/4") are provided in either side of the
regulator body for installation of a gauge or use as an
additional outlet port. Plug unused port(s). System piping
should be same size as regulator porting. In systems with a
cyclic demand, the regulator should be located upstream of
cycling device.

Operation

Maximum pressure rating is 300 psig (21 bar). Temperature
range is 32°F to 150°F (0°C to 65.5°C).

1. Before turning on the supply air pressure, turn the
