INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
4.8.2
O-Ring replacement
Remove the old O-Ring from the groove and clean the flange mating surfaces and the
groove, scraping carefully. Take care not to damage the mating surface and the
bottom and sides of the groove. Position it in the centre of its groove and push it
inside.
NOTE 1: Make sure that the proper O-Ring is re-inserted into the groove.
NOTE 2: The seat of an O-Ring gasket is dimensioned to allow the proper
positioning when compressed between the mating surfaces. Screws properly
tightened are important in obtaining a complete seal.
