ORAL-NASAL MASK
Step 1: Oral-Nasal mask (37) with
inhalation valve (34) and inhalation
valve housing (35).
Step 2: Line up and install
inhalation valve (34) with the
inhalation valve housing (35).
DO NOT lubricate the valve.
Step 3: Inhalation valve assembly
(34 & 35) for oral-nasal mask (37).
Step 4: Insert inhalation valve
assembly (34 & 35) into the
pocket on the left side of the
oral-nasal mask (37).
Step 5: Outside view of the
correctly installed inhalation
valve (34) and inhalation valve
housing (35).
Step 6: Insert second stage
regulator into the helmet
shell (1).
CAUTION: The head liner and oral-nasal mask must be used at all times
when diving. The head liner ensures that the oral-nasal mask maintains
a good fit on the diver’s face and reduces dead space in the helmet, this
helps prevent CO2 build up.
NOTE:
Inhalation valve must be installed on the inside of the oral-nasal mask. If
reversed it could cause serious problems including injury or death of the diver.
NOTE:
Refer to the separate Apeks Technical Manual:
GX300 REGULATOR FOR
THE AQUA LUNG G3000SS DIVING HELMET - MAINTENANCE MANUAL for
guidance on installation of the regulator.
