2 OPTIONS
2.1 UNIT IS AVAILABLE IN BOTH PFA AND PP CONSTRUCTION
The PFA unit exterior parts are molded using PFA (Fluoroplastic) and the shuttle
assembly is constructed of PEEK & PPS. The PFA unit is intended for severe
applications and for compliance with FM4910.
The PP unit exterior parts are molded using Polypropylene (Polyolefin) and the
shuttle assembly is constructed of PEEK & PPS. This unit is intended as a lower
cost option with similar service life where exposure to oxidizing acids is limited.

• Open the fluid suction (IN) line valve, if necessary.
• Open the fluid discharge (OUT) line valve, if necessary.
• Adjust the speed control screw fully Clockwise (CW) until fully retracted.
Warning! Do not apply too much torque to screw or damage may result.

• Open air supply line to operate pump. Operate pump at 20 psig initially to
prime pump.
CAUTION: When handling potentially dangerous fluids under pressure,
the pump and its fittings should be placed in an enclosure away from operators.

4.7 CLEAN-UP
Due to possible contamination all components must be flushed clean and
neutralized before disassembly to prevent fluid contact with personnel.
4.8 DISASSEMBLY
To disassemble PC7 pump controller for service, remove controller from pump by
disconnecting the flare fittings on the PC7 from the transfer tubes connecting it to
the pump.
Caution: For safety make sure air supply to PC7 has been shut off prior to
removal of supply line.
• Unscrew Adjustment Cap from controller body and carefully twist shuttle
spool from sleeve by rotating cap assembly.
• Gently remove the cap seal from the seat inside the cap to prevent any
damage or possible scratches to sealing surface. Replacement of seal is
recommended after service.
• Use a straight blade screwdriver to remove the two retaining screws from the
support plate. Next loosen compression nut and ferrule from adjustment
screw and gently push the adjustment screw out of the cap by pressing on
the end. This assembly contains the only serviceable items. See exploded
assembly for part numbers and part locations.
• Inspect parts for wear and replace if necessary.
4.9 ASSEMBLY
• To reassemble detent, twist the adjustment screw into the support plate and
then insert 2 each spring bars into slots as per figure 1.
• Next insert 2 each detent legs as shown in Figure 1 and open spring bars to
lock assembly as shown in Figure 2.

• Screw cap assembly with seal onto the open end of body assembly carefully
inserting shuttle spool into valve body and engage air seal completely.
• Cap requires only moderate installation torque to activate seal. Over
tightening can dislocate seal gasket preventing oscillation of the controller
valve.

5 TROUBLESHOOTING
Controller Will Not Operate or Cycles Erratically
Cause: Solution:
PC7 cap seal failure
•
Debris in shuttle valve
•
Insuffisant air pressure
•
Adjustment Screw Seal failure
•
Spring bar failure
•
Remove caps from PC7 and replace PTFE cap seal.
•
Isopropyl alcohol clean the shuttle sleeve and spool assy.
•
Increase regulated supply pressure or check control
•
valves for proper operation.
Rotate PC7 speed control screw CW until it stops. Then
readjust for correct speed.
Replace adjustment screw assy.
•
Spring bar needs replacement if not flat.
