WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.
Operation of Regulator
1. Before turning on air supply, turn adjusting handle counterclockwise until
compression is released from control spring. Then turn on air supply and
adjust regulator to desired secondary pressure by turning adjusting handle
clockwise. This permits pressure to build up slowly, preventing any unexpected
operation of the valve, cylinders, tools, etc., attached to the line. Adjustment
to desired secondary pressure can be made only with primary pressure
applied to the regulator.
2.
To decrease regulator pressure setting, always reset from a pressure lower than
the final setting desired. For example, lowering the secondary pressure from 550
to 410 kPa (80 to 60 PSIG) is best accomplished by dropping the secondary
pressure to 350 kPa (50 PSIG), then adjusting upward to 410 kPa (60 PSIG).
Operation of Filter / Regulator
1. Both free moisture and solids are removed automatically by the
Filter / Regulator.
2. Manual drain filters must be drained regularly before the separated moisture
and oil reaches the bottom of the element holder. Automatic drain models
(pulse drain) will collect and dump liquids automatically. They are actuated
when a pressure drop occurs within the filter.
3. The filter element should be removed and replaced when the pressure
differential across the filter is excessive.
Service
!
Caution: SHUT OFF AIR SUPPLY and exhaust the primary and
secondary pressure before disassembling unit. (Units may be serviced
without removing them from the air line.)
Servicing Regulator:
Note: See Figure 1, 2, 3 & 4 to aid with this procedure.
1. Unlock the adjusting knob by pulling upward (with the unit in an upright
position.) Then turn adjusting knob counterclockwise until compression of the
control spring has been removed.
2. Remove the bonnet from body. Then remove o-ring (7), piston, lip seal (9),
and control spring to service the bonnet subassembly. Unscrew seat (8) to
service the poppet (17), return spring (5), and/or poppet seal (6), o-rings (25
& 27), and washer (26).
Note: On Filter / Regulator units, the poppet assembly & poppet return spring
may be accessed by removing filter element.
3. Clean old grease from unit and inspect seals for sign of wear (nicks, cuts,
and scratches). Repair kits are available which contain the parts which are
typically replaced.
4. Apply a light film of grease to all seals and sliding surfaces using the grease
packet supplied with repair kit.
Note: Refer to Figures to determine the correct position and orientation of the
various parts during assembly.
5. On Relieving Economy Regulator units, gently and firmly press vent seal into
piston using a blunt instrument.
6. Install lip seal onto piston with the lips of the seal facing away from the
support flange. Then insert control spring and piston assembly into bonnet.
7. On Economy Regulator units, place balancing o-ring (27) and washer (26)
into body’s bore. Then insert poppet return spring and poppet assembly,
followed by seat o-ring (25) and seat. On Mini Regulator and Filter / Regulator
units, place poppet return spring and poppet assembly into bore, followed by
poppet seal and seat.

Installation
1. This unit should be installed with reasonable accessibility for service whenever
possible - repair service kits are available. Keep pipe and tubing lengths to a
minimum with inside clean and free of dirt and chips. Pipe joint compounds
should be used sparingly and applied only to the male pipe - never into the
female port. Do not use PTFE tape to seal pipe joints - pieces have a
tendency to break off and lodge inside the unit, possibly causing malfunction.
2. Install unit so that air flow is in the direction of arrow. Installation must be
upstream of and close to devices it is to service (valve, cylinder, tool etc.).
Mounting of Regulators may be in any position; mounting of Filter / Regulators
must be vertical as shown in figure.
3. Gauge ports are located on both sides of the regulator body for your
convenience. It is necessary to install a gauge or pipe plug into each port
during installation.
4. To protect Regulator units against rust, pipe scale, and other foreign matter,
install a filter on the upstream (high pressure) side as close to the regulator
as possible.
!
Caution: For proper assembly of units having plastic bodies, fittings
must be installed hand-tight and then tightened by wrench 1/2 turn. To
prevent leakage past threads, apply thread sealant to fitting. Prestolok
fittings are recommended. Use of hard pipe is not recommended.
EXCESSIVE TURNING OF FITTINGS BY WRENCH MAY RESULT IN
PERMANENT DAMAGE AND RENDER THE REGULATOR INOPERABLE.

8. On Economy Regulator units, tighten seat from 0.6 to 0.8 Nm (5 to 7 in-lbs).
On Mini Regulator and Filter / Regulator units, tighten seat to body from 0.9
to 1.1 Nm (8 to 10 in-lbs) of torque. Tighten bonnet onto body from 5.6 to
7.3 Nm (50 to 65 in-lbs) of torque.
9. Make sure that the control spring is still uncompressed before turning on
the
air supply. Turn on air supply, then slowly adjust the knob clockwise to
increase downstream pressure until the desired pressure has been reached.
10. To decrease regulator pressure setting, always reset from a pressure lower
than the final setting desired. For example, lowering the secondary pressure
from 550 to 410 kPa (80 to 60 PSIG) is best accomplished by dropping the
secondary pressure to 350 kPa (50 PSIG), then adjusting upward to
410 kPa (60 PSIG).
11. When the desired secondary pressure setting has been reached, push the
adjusting knob down to lock it.
12. Check for leaks. If leaks occur, shut off the air supply, exhaust system air
pressure, and make necessary adjustments to eliminate leakage.
Servicing Filter Element:
Note: See Figure 1 to aid with this procedure.
1. Unscrew threaded bowl and element holder. Then remove filter element,
deflector, and gaskets.
2. Clean all internal parts, bowl, and body before re-assembling unit. See
Polycarbonate bowl cleaning section.
3. Install deflector, filter element, and gaskets.
4. Attach element holder. Torque 0.9 to 1.4 Nm (8 to 12 in-lbs).
5. To assist with retaining bowl’s o-ring while installing bowl, lubricate the o-ring
(with a mineral based oil or grease). Then place it on the bowl.
6. Screw bowl into body until it is stopped by body; then back off bowl 1/8 turn.
7. Apply pressure to the system and check for leaks. If leaks occur, shut off the
air supply, de-pressurize the system and make necessary adjustments to
eliminate leakage.

SAFETY: Transparent Bowls
CAUTION
Polycarbonate bowls, being transparent and tough, are ideal for use with Filters
and Lubricators. They are suitable for use in normal industrial environments, but
should not be located in areas where they could be subject to direct sunlight, an
impact blow, nor temperatures outside of the rated range. As with most plastics,
some chemicals can cause damage. Polycarbonate bowls should not be exposed
to chlorinated hydrocarbons, ketones, esters and certain alcohols. They should
not be used in air systems where compressors are lubricated with fire resistant
fluids such as phosphate ester and di-ester types.
Metal bowls are recommended where ambient and/or media conditions are not
compatible with Polycarbonate bowls. Metal bowls resist the action of most such
solvents, but should not be used where strong acids or bases are present or in
salt laden atmospheres. Consult the factory for specific recommendations where
these conditions exist.
TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER ONLY!
DO NOT use cleansing agents such as acetone, benzene, carbon tetrachloride,
gasoline, toluene, etc., which are damaging to this plastic.
Bowl guards are recommended for added protection of Polycarbonate bowls where
chemical attack may occasionally occur.
