Disconnect the active pressure relief valve connector X8 from the pneumatic
assembly PC board.

solenoid.

6.
Unscrew the four screws of the free breathing valve retainer.
7.
Remove the free breathing valve retainer and the free breathing valve from the
pneumatic assembly.
8.
While inserting the free breathing valve pay attention to proper seating.
Incorrect seating (e.g. with incorrect tension on the valve’s silicon springs) can
cause leaks.

The stainless steel rod, that connects with the over pressure relief valve, opens the
free breathing valve when activated. Ensure free moving of the rod after reassembly
of the over pressure relief valve.
