UNIT MAINTENANCE PROCEDURES
GENERAL MAINTENANCE
d. Repeat a, b, and c for the other pipe end. One side must be pushed far enough on to
allow the pipe joint to clear the other pipe end.
e. Fit the pipe joint onto one pipe end. Move the pipes back into alignment.
f. Slide the assemblies at both ends up to the pipe joint so that both gaskets fit up against
the flanges of the pipe joint.
g. Position the clamps over the pipe joint flanges and gasket retainers and secure loosely
with a bolt and nut. When both are installed loosely, tighten the bolt and nut on both
clamps.
h. Tighten the pipe connections and pipe support clamps that were loosened to move the
pipes.
i. Spray the gasket retainers and clamps with the corrosion preventive compound.
j. Run the unit and check the joint for leaks.
