FM60-7309 Operator’s Manual

3.Remove the bottom collar and bowl as an integral unit. Note: The reverse flow adapter and element assembly should remain in proper alignment with the collar; they are held in place by the o-ring between the adapter and the collar.

4.Remove diaphragm

assembly from bonnet assembly.

5.Remove poppet assembly, poppet return spring, (seat) insert and its o-rings.

6.Clean and carefully inspect parts for wear or damage. If replacement is necessary, use parts from service kits.

7.Lubricate o-ring and vee packing seals with grease found in service kits.

8.Install poppet return spring, poppet assembly, (seat) insert and its o-rings.

9.Install diaphragm assembly into bonnet assembly. Assemble

bonnet assembly to body and tighten threaded collar from 5.4 to 5.9 N•m (48 to 52 in-lbs).

10.Install bottom collar and bowl subassembly into body. Tighten collar hand tight, plus 1/4 turn.

Safety: Polycarbonate Bowls

Bowl guards are recommended for added protection of polycarbonate bowls where chemical attack may occur.

WARNING To avoid polycarbonate bowl rupture that can cause personal injury or property damage, do not exceed bowl pressure of temperature ratings. Polycarbonate bowls have a 150 psig (1030 kPa) pressure rating and a maximum temperature rating of 52°C (125°F).

WARNING

To avoid unpredictable system behavior that can cause personal injury and property damage:

•Disconnect electrical supply (when necessary) before installation, servicing, or conversion.

•Disconnect air supply and depressurize a[ air lines connected to this product before installation, servicing, or conversion.

•Operate within the manufacturer’s specified pressure, temperature, and other conditions listed In these instructions.

•Medium must be moisture-free if ambient temperature is below freezing.

•Service according to procedures listed in these instructions.

•Installation, service, and conversion of these products must be performed by knowledgeable personnel who understand how pneumatic products are to be applied.

•After installation, servicing, or conversion, air and electrical supplies (when necessary) should be connected and the product tested for proper function and leakage. If audible leakage is present, or the product does not operate properly, do not put into use.

•Warnings and specifications on the product should not be covered by paint, etc. If masking is not possible, contact your local representative for replacement labels.

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 P3A-RN and 8AR fittings, they 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.

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
