To wash the head cushion, place it in a solution of
mild dish soap. Lightly brush the fabric with a soft
nylon brush to remove perspiration and skin oil, then
rinse thoroughly. Squeeze out excess water from the
head cushion and hang to dry in a safe place.
To ensure that the head cushion is dry for future use
you may want to remove the head cushion foam.
However, do not remove the foam unless it is abso-
lutely necessary. Given enough time the head cushion
will dry properly without removing the foam.
5) If the head cushion is wet, the chin cushion is prob-
ably wet. Like the head cushion, the chin cushion is
fastened into the helmet with snaps. Follow the same
cleaning instructions as for the head cushion.
6) Loosen and remove the nose block knurled knob
then loosen the packing nut and remove the nose
block device and oral nasal mask. Clean and sanitize
the nose block device and oral nasal mask then rinse
thoroughly and set them aside to dry. Make certain
that the oral nasal valve seat and valve are clean of
debris.
7) Remove the communications assembly from the
helmet so it can dry completely. Remove the ear-
phone covers from the earphones so they can dry
completely. Clean the microphone with sanitizing
solution, rinse it, and allow it to dry.
Uncover the earphones so they may dry.
8) Wash the exterior of the helmet with a mild soapy
water solution and rinse thoroughly with fresh wa-
ter. Turn the defogger valve knob, emergency valve
knob, and regulator adjustment knob while rinsing
to prevent salt from accumulating under these areas.
Operate the sealed pull pins as you run water over
them.
Wipe the inside of the helmet out with a clean, damp
rag. Do not depress the purge button while rinsing
the regulator as this action will permit foreign matter
back into the inlet valve and seat.
Remove the demand regulator clamp by removing
the clamp screw. Lift off the regulator cover and
diaphragm then clean all components and swab
out the interior of the regulator with the sanitizing
solution as per the sanitizing procedure. Ensure the
dewatering valve gets cleaned. Note: avoid depress-
ing the purge button to minimize water entering the
inlet valve. Visually inspect the interior of the regu-
lator and thoroughly check the diaphragm. Dry the
diaphragm, seating area in the regulator and the rim
of the cover assembly. Reinstall all parts and tighten
clamp screw properly.
After cleaning and sanitizing, rinse thoroughly. Wipe
out the inside of the helmet with cleaning solution,
pour solution into the exhaust area and work into the
regulator cavity and exhaust area allow to remain in
contact for the required time then thoroughly rinse
all surfaces.
9) Screw the demand regulator adjustment knob all
the way out. This will prolong the life of the inlet
valve and keep the internal adjustment correct.
10) If the neck dam is damaged it should be replaced.
B
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 free flow. Serious injury, drowning
or death may result. A damaged neck
dam should be replaced.
11) Reinstall the oral nasal mask, Lubricate the nose
block shaft then reassemble and tighten.
12) Reinstall the head and chin cushions when dry.
