17B

Diaphragms showing any indication of damage

should be replaced. The diaphragm should always be

replaced during scheduled annual overhauls.
6) Inspect the whisker wings. Replace the whisker

wings if they show signs of wear, aging or any dam

age.
The new whiskers used in the Quad-Valve™ are

much more rugged than the older latex double exhaust

system and will give a much longer service life and

provide better breathing performance at depth. Older

latex double exhaust systems should be replaced with

the new Quad-Valve™ exhaust system.
