Wilkerson B08 - Manual

INSTALLATION
1. Refer to the above WARNING before installing filter/regulator.
2. Make sure that system piping and filter/regulator are the same pipe
size. Avoid using fittings, couplings, etc. that restrict airflow.
3. Install unit as near as possible to filtered/regulated air application.
4. Position unit so air flows in direction indicated by arrow on the top of
filter/regulator body.
5. Install filter/regulator in a vertical position with bowl side down.
6. To install a drain line, use the following procedure:
a. On units with the MANUAL DRAIN, attach flexible tubing having an
I.D. of 5/32" (4 mm) to drain stem.
b. On units with the AUTOMATIC PISTON DRAIN attach flexible tubing
having an I.D. of 1/4" (6 mm).
7. To install using L-Type (wall mount) bracket, fit bonnet threads into
bracket hole. Replace panel nut and tighten.
OPERATION
1. Maximum pressure rating is 150 psig (10.3 bar) for transparent
plastic bowls, and 250 psig (17.2 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.
2. To adjust filter/regulator pull up on adjusting knob.
3. Before turning on supply air pressure, turn the adjusting knob
counterclockwise until there is no load on the regulating main spring.
4. To set the downstream pressure turn on the supply air pressure and then
turn the adjusting knob clockwise until the desired secondary pressure is
reached. Push the adjusting knob down to lock knob in place.
5. When making a change in pressure setting, always approach the
desired pressure from a lower pressure. When reducing from a higher
to a lower setting first reduce to some pressure point less than that
desired and then increase to the desired pressure.
MAINTENANCE
1. Given normal operating conditions this unit will be trouble-free. For
long service life, occasionally disassemble and clean body, diaphragm,
valve and valve seat. Service unit at least every 6 months.
2. TO REPLACE OR SERVICE VALVE ASSEMBLY:

and baffle to 8-10 lb in. (0.90-1.1 N-m).
j. Before returning to service, insure that all seals have been reinstalled
or replaced.
k. Reinstall bowl and bowl guard assembly and rotate bowl guard

f. Reinstall diaphragm assembly with spring rest in the up position.
g. Place main spring on spring rest.
h. Align bonnet assembly into body. Turn bonnet clockwise and tighten
to 5 lb/ft (6-8 N-m).
i. Slowly pressurize unit to assume proper seating of all components.
4. IF UNIT WILL NOT REGULATE TO DESIRED PRESSURE OR IF
DOWNSTREAM PRESSURE BECOMES EXCESSIVE, disassemble, clean
and check valve O-ring, valve stem and valve seat for wear or damage.
Replace worn or damaged parts with original manufacturer’s service parts.
5. TO CLEAN OR REPLACE BOWL ASSEMBLY:
a. Depressurize unit.
b. Remove bowl and bowl guard assembly by turning counterclockwise.
