INSTALLATION
Install the Filter/Regulator as close as possible to the application. The
inlet port is marked with an arrow cast into the body to indicate the
direction of flow. Gauge ports (1/4") are provided in either side of the
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 150 psig (10 bar) for transparent
plastic bowls, and 200 psig (14 bar) for metal bowls.
Temperature range is 32°F to 125°F (0°C to 52°C) for transparent
plastic bowls, and 32°F to 150°F (0°C to 65.5°C) for metal bowls.
Before turning on the supply air pressure, turn the adjusting knob
counterclockwise until there is no load on the regulating spring. Turn
on the supply air pressure and then turn the adjusting knob clockwise
until the desired secondary pressure is reached. To avoid minor
readjustment after making a change in pressure setting, always
approach the desired pressure form a lower pressure. 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.

UNSUITABLE FOR USE WITH POLYCARBONATE BOWLS
MAINTENANCE
1. The regulator can be disassembled for servicing without removal
from line.
2. DEPRESSURIZE UNIT BEFORE REMOVING GUARD AND/OR
BOWL.
3. TO DISASSEMBLE: shut off air to the filter/regulator and vent air
line on both sides of unit. Turn adjusting screw counterclockwise
to relieve spring compression. Remove knob, cover cap, screw
cover, and spring. Diaphragm assembly can now be removed.
4. To remove valve from bottom of unit, remove bowl. Remove baffle
and filter element exposing hex nut on adapter assembly.
Remove adapter assembly, valve and spring.
