water solution. Rinse the exterior of the helmet
thoroughly with fresh water. Turn the defogger
valve knob, emergency valve knob, and regulator
adjustment knob while rinsing to prevent salt from
accumulating under these valves.
7) Remove the regulator cover, clamp and dia-
phragm, and wash the interior of the regulator with
a mild solution of soapy water. Run water through
the air delivery tube located in the oral nasal.
Do not depress the purge button while rinsing the
regulator as this action will permit foreign matter
back into the inlet valve and seat.
8) Wash the interior of the helmet and oral nasal
mask with a soapy water solution and rinse with
fresh water.
9) Screw the demand regulator adjustment knob all
the way out. This will prolong the life of the inlet
valve seat and keep the internal adjustment correct.
Close the emergency valve and steady flow valves.
10) Lubricate the shaft of the nose block device with
silicone lubricant.
11) Rinse the neck dam assembly and allow to dry.
Remove the O-ring from the bottom of the helmet,
clean and lubricate.
WARNING
Avoid patching a torn or punctured neck
dam. If the patch comes off underwater the
helmet could flood and/or cause the demand
regulator to freeflow. Serious injury, drown-
ing or death may result. A damaged neck
dam should be replaced.
The neck clamp and latch catch must operate properly. They
must be regularly inspected and serviced.

12) If the neck dam is damaged it should be replaced.
13) Operate the neck clamp and latch catch as you

move water droplets and allow to dry.
The nose block O-rings must be regularly lubricated.
The o-ring on the base of the helmet must be in good
condition.
