Installing a Manifold Assembly
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.
All Mattress Replacement and Overlay Systems except Alpha Trancell II
9.1
Lay the manifold assembly onto the side of the mattress, with the tube connections to the pump
at the feet end of the mattress and the CPR end plug assembly at the head end. Align the T-
connectors on the cells with the cut-outs in the manifold tubes.
Note:
Refer to the relevant figure in this chapter to make sure the loop base sheet assembly
and the cells and manifold assembly are in the correct positions.
Note:
On some systems, there are no pump connectors, just open tubes, and/or stoppers
replace the CPR end plug assembly, but the manifold orientation is the same.
9.2
On mattresses with a base cover assembly, feed the “pump” ends of the manifold tubes out of
the mattress through the hole in the base cover assembly.
9.3
Connect all the cells to the manifold assembly, as follows:
9.3.1
Carefully insert the two ends of the T-connector into the manifold tubes.
9.3.2
Connect the press studs that secure the end of the cell to the loop base sheet
assembly on the manifold side.
9.4
Install the top cover (Refer to Page 37, Section 4).
Alpha Trancell II Mattress Overlay only
9.5
Lay the manifold assembly next to the mattress overlay assembly, with the CPR end plug
assembly at the head end of the mattress. Align the T-connectors on the manifold assembly with
the side-entry grommets on the mattress overlay assembly (Refer to Figure 10).
9.6
Carefully insert the 16 T-connectors on the manifold assembly into the side-entry grommets on
the mattress overlay assembly.
9.7
Install the top cover (Refer to Page 37, Section 4).
All Seat Systems
9.8
Lay the manifold assembly onto the mattress or seat, with the tube connections to the pump at
the feet end of the mattress and the CPR end plug assembly at the head end. Align the T or
elbow connectors on the manifold tubes with the side-entry grommets on the cells.
Note:
On some systems, there are no pump connectors, just open tubes, and/or stoppers
replace the CPR end plug assembly, but the manifold orientation is the same.
9.9
On some seat types, feed the “pump” ends of the manifold tubes out of the seat through the hole
in the loop base sheet assembly.
9.10
Connect all the cells to the manifold assembly, as follows:
9.10.3
Carefully insert the end of the T-connector into the side-entry grommet on the cell.
9.10.4
Connect the press studs that secure the end of the cell to the loop base sheet
assembly on the manifold side.
9.11
Install the top cover (Refer to Page 37, Section 4).
