Catalyst Overpressure Valve (Polyester option only)

See drawing 22021

Under normal operational circumstances the catalyst overpressure valve is

maintenance free.

If catalyst leaks constantly from fitting (4), O rings (2) must be replaced

Important Note: It is essential that the internal spring tension is not disturbed in the event

of servicing this unit.

Procedure

To renew front O rings

1. Disconnect red signal pipe and clear overflow pipe. Unscrew whole assembly from catalyst

pump using 19 AF spanner on the forward stainless steel body taking care of any small

residual pressurised catalyst as thread seal is broken. DO NOT disturb the spring tension

end cap (0671).

2. Hold brass body (1035) and unscrew stainless steel body (1032). Pull shaft (1034), and

collar (1033) from body, replace O rings (0750) and reassemble. Ensure shaft is reinserted

with rounded end into the body.

3. Reassemble observing order illustrated in dwg. 22021. Ensure bodies (1032) and (1035)

are correctly screwed together using PTFE tape or similar thread sealant.

4. Reattach valve to catalyst pump using thread sealant.

5. Reprime catalyst system to remove any air from the system.
