Installing flange adapter
Table 13 gives the steps for an optional flange adapter on the process head.
ATTENTION
Slightly deforming the gasket supplied with the adapter before you insert it into the adapter
may aid in retaining the gasket in the groove while you align the adapter to the process head.
To deform the gasket, submerse it in hot water for a few minutes then firmly press it into its
recessed mounting groove in the adapter.
Step
1 Insert filter screen (if supplied) into inlet cavity of process head.
2 Carefully seat Teflon (white) gasket into adapter groove.
3 Thread adapter onto 1/2-inch process pipe and align mounting holes in adapter with holes in
end of process head as required.
4 Secure adapter to process head by hand tightening 7/16-20 hex-head bolts.
Example - Installing adapter on process head.
ATTENTION
Apply an anti-seize compound on the stainless steel bolts prior to threading them into the
process head.
