together, so remove the retaining ring and one of the rubber
sealing washers.
2. Check that the remaining rubber sealing washer is laying
flat against the valve body.
3. Locate the thread on the exhalation valve assembly through
the hole in the back of the suit.
4. Locate the second rubber sealing washer around the thread
on the valve body so that it is laying flat against the material
of the suit .
5. Hand tighten the retaining ring onto the exhalation valve.
6. Check that the exhalation valve is orientated correctly (the
lettering should be at the top of the valve and the three slots
under the cover must be at the bottom).

No. G01486).
