INSTALLATION
1. Read all Cautions and Warnings before installing
this unit.
2. Install as close to the point of use as possible. It
is advisable to install a particulate filter on the
inlet side of this product to extend the unit’s ser-
vice life and to minimize the frequency between
necessary maintenance periods.
3. Units must be installed with the free flow in the
direction of the flow arrow. The adjusting knob
may be oriented in any position relative to the
pipe.
4. Avoid using reducing bushings, couplings, etc.,
whenever possible when installing this product.
These devices restrict air flow and can affect
performance.
OPERATION
1. Before turning on system air pressure, turn
adjustment knob full counterclockwise. This
will close regulator to produce zero air pressure.
2. Turn on system air pressure.
3. To increase regulated pressure, pull adjusting
knob up and turn clockwise. To reduce pressure,
turn knob counterclockwise. To lock the knob,
push the knob down.
4. To avoid minor readjustment after making a
change in pressure setting, always approach
the desired setting from a lower pressure.
When reducing pressure, first reduce to some
pressure less than that desired, then bring up to
the desired point.
MAINTENANCE
Do not submerge regulator or components in sol-
vent or use solvent to clean regulator parts. Dam-
age may occur to regulator and components. Use
a cloth dampened in warm, soapy water to clean
exterior of regulator.
Note
This unit may be serviced without removing the unit
from the compressed air line.
1. Frequency of servicing depends largely on the
condition of the compressed air system and the
degree of contamination in the system.
2. Before attempting to service this product in-line,
depressurize both the upstream and downstream
sides of regulator.
3. Remove the bottom plug, valve spring and valve
assembly. Inspect all seals and components for
damage and replace as required. Clean seals
and components with mild detergent and water.
Use a clean, dry cloth to wipe any contamination
from valve seal inside the body. Lubricate the
valve stem and lower valve o-ring seal with a
light coat of MAGNALUBE-G or similar lubricant.
Reassemble. Bottom plug torque should not
exceed 25 in./lbs (2.8 N-m).
4. To replace main spring or diaphragm, turn
adjusting knob counterclockwise to remove all
spring force, then remove bonnet. Remove the
adjusting screw assembly, main spring, slip ring
and diaphragm assembly. Inspect the diaphragm
and the relief seat for damage and contamination.
Replace diaphragm assembly if necessary. Clean
the relief seat with a soft dry cloth. Reassemble in
reverse order making sure the slip ring is properly
positioned on top of the diaphragm. Bonnet
torque should not exceed 120 in./lbs. (13.6 N-m).
5. Before returning unit to service, ensure that all
seals have been properly reinstalled or replaced
and components requiring torque values have
been properly set.
6. If regulated pressure begins to creep (an
uncontrolled rise in regulated pressure), it will
most likely be caused by contamination on the
valve seat.
7. If the unit leaks from the vent holes in the bonnet,
it may be caused by contamination, deterioration
or damage to the valve seat or diaphragm relief
seat. Replace any damaged or worn components.
