Replacing the CPR/Rapid Deflate End Plug Assembly
Most, but not all, mattress replacement and overlay systems have a cardiopulmonary resuscitation
(CPR) or Rapid Deflate plug to allow rapid deflation of the mattress replacement or overlay system. None
of the seat systems have a CPR or Rapid Deflate plug.
The CPR (or Rapid Deflate) end plug assembly is located at the head end of the mattress replacement
or overlay, on the same side as the manifold.
10.1
Remove the top cover (Refer to Page 36, Section 3).
10.2
At the head end of the mattress, on the manifold side, move the base cover assembly and loop
base sheet assembly (including cells) out of the way to reveal the CPR end plug assembly.
10.3
Replace the following parts on the CPR end plug assembly as necessary (Refer to Figure 26):
•
End plug, 2-way
•
Clevis pin
•
Swing label and web assembly
•
Straight connector, male-male
Note:
Make sure that the CPR end plug assembly fits tightly into the manifold tubes and that
the clevis pin is securely fitted before inflation, so that no air escapes.
Note:
Installing the end plug or straight connectors is made easier if the parts are wetted with
methylated spirit immediately prior to insertion.
10.4
At the head end of the mattress, lay the base cover assembly and loop base sheet assembly
(including cells) back in their correct positions.
10.5
Install the top cover (Refer to Page 37, Section 4).
