period.”

CAUTION
Germicidal cleansing solutions must
be carefully diluted if required in ac-
cordance with the manufacturer’s rec-
ommendation. If solution is not of the
recommended strength, it will not act
as an effective disinfectant. Failure to
thoroughly rinse germicidal cleansing
solution from diving equipment may
result in lung irritation and/or long-
term degradation of rubber and sili-
cone components of this equipment.
6.4 Daily Maintenance
The following steps must be performed daily at the
completion of diving operations.
1) Disconnect the helmet from the diving hose and
EGS cylinder. Make sure the air is off and the breath-
ing system of the helmet is unpressurized. To vent the
system, open the defogger valve knob and emergency
gas valve knob until all gas flow stops.
B
WARNING
Never disconnect any hose from the
helmet unless all gas has been vented
from the hose first. If the hose is dis-
connected with pressure in the line
the fittings may be damaged. In addi-
tion, the hose can whip about causing
injury to anyone standing nearby.
2) Place a protective cap over both the air inlet and
the emergency valve inlet to prevent foreign matter
from entering the valves. Shut all valves.
Cover the air inlet and emergency gas valve openings with
dust caps when not in use.
3) Remove the neck dam/neck ring assembly, clean
with sanitizing solution, rinse thoroughly and allow
to dry. Remove the O-ring from the neck dam ring,
clean and lubricate. Clear O-ring grove, then reinstall
O-ring.
4) If the head cushion is wet, remove it from the
helmet. The head cushion is fastened into the helmet
with snap tabs and pulls out easily.
Removing the head cushion.
