Super 300 Type Pillar™ Process Fluid Inlet and Outlet Connections:
Super 300 Type Pillar ™ process fluid connections are available for the LTFH filter
housings. Super 300 Type Pillar Fittings use a "gauge ring" which is used to determine
the proper tightness of the fitting connections.
1) Remove the protective plastic caps from the fittings on the Inlet and Outlet piping
of the heater assembly.
2) Install appropriately sized Super 300 Type Pillar "gauge ring"
3) Tighten the Pillar fitting nut until the bosses on the union nut makes contact with
the gauge ring and pulls the blade. A clicking (crunching) sound will be heard at
this point. Continue tightening the union nut until the bosses make full contact
with the gauge ring.
