Installing a Cell
Note:
There are several different cell assemblies in the various mattress replacements, overlays and
seat systems detailed in this service manual. Make sure the cell assembly is the correct type for
the particular mattress or seat, and also for the position within the mattress (where applicable).
Note:
Make sure the orientation of the cell is correct (Refer to Figure 25). The seams should be facing
the feet of the mattress.
Note:
Installing the T or elbow connectors into the manifold tubes or side-entry grommets on the cells
is made easier if the parts are wetted with methylated spirit immediately prior to insertion.
