44 | INSTALLATION, OPERATION and MAINTENANCE MANUAL
installed in the proper sequence, that gaskets are fully or securely seated in their
grooves, and there is no debris on the plates or gaskets. Clean the gasket sealing
surface with a lint free cloth. Push each plate firmly against the previous one. Use
special care with mechanically retained gaskets (gaskets clipped to the plates) to avoid
dislodging them (Figure 39).
Do not permanently bend or scratch the plates or damage the gaskets during
installation. Some plates must be carefully flexed to install them.
Note: The plate arrangement on the customer drawing indicates whether the gasket
side of the plate faces the head or follower.
Perform a final pre-tightening inspection after all plates have been added. Count the
number of plates at least twice, preferably three counts, to ensure the counts match the
plate quantity on the customer drawing. Inspect the sides of the plate pack for alignment
and continuous orientation pattern. When the plate pack has been correctly assembled,
in most models, plate edges will create a honeycomb pattern.

pack. Install the tie bars into the frame holes or key-hole slots as specified by the
tightening instructions below.
