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 re resistant uids 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
at laden atmospheres. Consult the factory for specic 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.
various parts during assembly.
5. On relieving 15R units, gently and rmly 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
ange. Then insert control spring and piston assembly into bonnet.
7. On 15R 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 14E, P3A-RN, 8AR & 14R units, place poppet return spring and poppet
assembly into bore, followed by poppet seal and seat.
8. On 15R units, tighten seat from 0.6 to 0.8 Nm (5 to 7 in-lbs). On 14E, P3A-RN,
8AR & 14R 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 nal 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 lter element,
deector, and gaskets.
2. Clean all internal parts, bowl, and body before re-assembling unit. See
Polycarbonate bowl cleaning section.
3. Install deector, lter 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. If you have questions concerning how to service this unit, contact your local
authorized dealer or your customer service representative.
