Note
The system was drained to avoid leaking at this connection when the clamp is loosened. Loosening the
clamp allows the upper and lower manifolds to move relative to each other.

Note
The shims position the module slightly higher than normal. This insures that after alignment the module
can slide up slightly and onto the manifold connector. This is done to insure that the manifold connectors
are a little higher than the module connectors.

connectors.
Note
The manifold may have to be moved slightly to allow proper alignment between module connectors and
manifold connectors. Do not aggressively insert or damage to the connectors may result.
