Tips for Connecting Tunnel Units on Site
In most installations, the tunnel is composed of two or more units that you must connect together
on site. Use this instruction to help prevent damage.
1.
Protect the inter-unit seal.
When you connect units, the correct procedure is to establish the final position of the press or
extractor, then move the tunnel units into position, from discharge end to load end. Before you
move units together, apply petroleum jelly to the outer surface of the discharge chute on the load-
end unit and to the surface of the inter-unit seal on the discharge-end unit. Without lubrication,
the seal can tear or get pulled so that it is pointing in the wrong direction.
2.
Align the units.
Use leveling instruments to make sure that the two units remain level horizontally when you
bring the them together. When you start to insert the discharge chute, keep them aligned
vertically and horizontally plus or minus 1/4" (6 mm), otherwise you can damage the inter-unit
seal. When the adjacent connection flanges on the two units are close together, use the
corresponding bolt holes as a guide to align the units precisely. When the flanges are touching
and you can put the bolts through both holes with the units level, the units are aligned.
3.
Check for correct seal orientation.

See Figure 1 . If you had to move the load-end unit out and back in during connection, this can
pull the seal to the wrong orientation. Reach into the gap where the discharge chute enters the
throat of the other unit. If you feel the seal pointing outward, use a wooden stick with a smooth
end to push the seal back to the correct orientation.
