NOTE: It is necessary to first remove the regulator and exhaust assembly from the helmet to replace the exhaust valves.

7.9.2.1 Quad-Valve™ Exhaust Valve Replacement

1)Remove the Quad-Valve™ Assembly from the regulator.

2)Carefully remove the two whisker clamps that hold the deflector whiskers to the main exhaust body .

NOTE: The exhaust valve and whisker exhaust valve inserts must be placed into the Quad-Valve exhaust main body correctly to provide gas flow in the proper direction. The flow must be from the inside of the Quad-Valve exhaust main body out to starboard whisker and port whisker.

5)Install an exhaust valve/whisker exhaust valve insert assembly into both seating areas on each side of the exhaust main body.

3)Remove the two exhaust valve inserts and valves. Carefully note which side the valves are installed into and which way they face when mounted in the body. They MUST be reinstalled facing the same way. See the illustrations below.

4)Install a new exhaust valve into each whisker ex- haust valve insert on the correct side by feeding valve tail through hole in center of valve insert and pulling on it until valve is seated.

To allow access to the two exhaust valves in the Deflector Whiskers™, you must first remove the two whisker clamps that hold the whiskers on the exhaust main body.

WARNING

The exhaust valve inserts must be in- stalled in the correct orientation in exhaust main body. If the inserts are in- stalled backwards, the diver will be unable to exhale. This could lead to suffocation and death.

The exhaust valve inserts are recessed on one side to accept the exhaust valves so they sit flush in the inserts. The exhaust valves must be installed properly in the inserts or they will not seal or perform properly.
