Installation steps
If a flushing ring is ordered and no alignment clamp is used, it is recommended that two
people install the FFW flush flanged seal to ensure proper alignment during installation.
Follow these steps to install the FFW flush flanged seal on an existing flanged process
connection:
Procedure
1. Remove the protective cover from the diaphragm of the remote seal. Use extreme
caution during installation to ensure the diaphragm is not damaged.
2. If installing a flushing ring, ensure flushing connections are sealed before
completing installation. Flushing rings may be ordered with or without, one or two
threaded flushing connections, factory supplied plugs, or drain vent valves. If no
flushing ring was purchased, proceed to
. Assemble the flushing ring,
Emerson-supplied gasket, and remote seal together. If using an alignment clamp
(option code SA) attach the flushing ring to the remote seal. Place the alignment
clamp in the machined groove on both the remote seal and the flushing ring. Using
the applicable screwdriver, tighten the screw on the clamp to hold the flushing ring
in place.
3. Insert end-user-supplied bolts in the bottom two bolt holes of the flange on the
remote seal.
4. Place the appropriate end-user-supplied gasket on the remote seal or flushing ring
and align the gasket so that it is not inside the diaphragm weld as this will induce
errors.
WARNING
Failure to properly install the gasket may cause process leaks, which can result in
death or serious injury.
5. Using the previously installed bolts, attach the remote seal and gasket to the
process connection. Secure with nuts and hand-tighten.
6. Insert end-user-supplied bolts in the top two bolt holes of the flange on the remote
seal. Secure with nuts and hand-tighten.
7. Using a torque wrench on the nut, tighten the assembly in a cross-pattern to ensure
even installation (see
). The bolts should be torqued to the
applicable flange requirements. Required torque is a function of the gasket material
and surface treatment of the bolts and nuts which are end-user-supplied. Consider
leak checking the installation to ensure a robust connection.
