1. Cut individual glass fiber rope seals and secure each
cut end against fraying by taping it with the supplied
masking tape.
CAUTION
The rope gaskets must be cut to exact lengths.
No openings between gaskets are acceptable.
Working from the rear section to the front section
requires the gasket only on the front side of the
section. Do not double gasket.
2. Lay each section flat, the side to be gasketed facing
up. Apply the supplied glue into the pre-cast grooves.
Allow the glue to dry approximately five minutes.
CAUTION
During the application of the glue, ensure proper
ventilation of the work area.
3. Press the three glass fiber rope seals properly into the
grooves while the cast iron section is still flat on the
ground. The ends of the rope must properly meet.
No openings between gaskets are acceptable.
4. Check both nipple ports for burrs and, if necessary,
remove burrs with a file. Never apply file in an in-and-
out motion on the nipple port, only in a circular motion
on the push nipple port sealing area. Clean the nipple
ports and nipple port face with solvent, dry properly
and paste with supplied linseed oil.
5. Clean both push nipples with solvent, dry and paste
with supplied linseed oil.
6. Insert push nipples into nipple ports and secure with
gentle hammer taps (wood or rubber mallet only).
Ensure push nipples are inserted evenly by tapping
in a cross-wise fashion. Remove any burrs, if necessary.
7. Prepare an intermediate section according to steps
1 through 6. Arrows on the intermediate section must
point toward the rear section.
