INSTALLATION
Clean pipe lines to remove dirt and scale be ore installation is made. Apply minimum amount o
pipe compound to male threads o air line to avoid possibility o getting compound into regulator.
Install regulator in air line, body is itted with a 1/4" or 3/8” NPT or inlet and outlet connections.
Regulator can be mounted in any position without a ecting its operation. Inlet and outlet
connections are labeled ( look or arrows denoting direction o low on underside o unit ) and
should be tightened securely. Avoid undersized ittings that will limit low through the regulator and
cause pressure drop downstream. The use o a ilter to remove dirt and entrained liquid in the air
line ahead o the regulator is recommended or best per ormance. I an air line lubricator is used ,
it should be located downstream beyond the regulator in order to avoid inter erence with the
regulator per ormance.
NOTICE
The presence o certain diester oils in the airlines may hasten deterioration o the elastomers and
thus decrease the use ul li e o this unit.
ADJUSTMENTS
No ield adjustments are necessary.
OPERATION
Relieve pressure on range spring be ore putting regulator into service or the irst time. When
operating at pressure above atmospheric, turn the adjusting screw slowly in a clockwise direction
until required downstream pressure is obtained. For pressure below atmospheric, turn the
adjusting screw counterclockwise until the desired setting is obtained. Turned in a clockwise
direction, the screw compresses the range spring causing increased output pressure. For
decreased output pressure, or set a lower vacuum setting, turn the screw counterclockwise.
MAINTENANCE
The Regulator is easily disassembled or the occasional cleaning or removal o oreign matter.
Be ore this is done, however, shut o valve upstream o the regulator to prevent escape o air
when regulator is disassembled. Also shut o the controlled vacuum to avoid pressurizing the
system. There is no need to remove the regulator rom the pipe line, remove the two No.10 - 32
screws on the bottom o the unit and pull out the inner valve assembly. Wash inner valve
assembly with solvent exercising care to avoid damaging diaphragms and valve acings. Replace
assembly care ully. The vent hole in the bonnet should be kept clear. The adjusting screw should
be lubricated with Molycote type “G” grease.
CAUTION
(Avoid such solvent as acetone, carbon tetrachloride, trichlorethylene)
