Regulator Exhaust Tees
The size of the regulator mouthpiece tube and size of the exhaust tees can
affect performance of the mask. An incorrectly installed regulator can lead
to flooding of the mask, which may result in serious injury or death. If the
regulator has exhaust tees, ensure they do not interfere with the mask and
there is a clear path for gas to exhaust.
DONNING AND DOFFING PROCEDURES
Warning Note
ALWAYS inspect your diving equipment to ensure it is not damaged or
defective and that it is fully functional. DO NOT dive the Spectrum FFM or
any other equipment if you have not verified that it is in good condition and
working properly! If this equipment has been damaged, tampered with, or
found to be defective, return it to OTS or replace components immediately.
Overall Safety Inspection
Prior to donning the Spectrum FFM, examine the complete assembly along
with the rest of the gear to ensure that it is in dive-ready condition. The
diver is ultimately responsible for his/her equipment. Check all buckles,
strap assembly, visor clamp assembly, visor, skirt, inner frame and
regulator. Then extend all straps and prepare to don the mask. Establish
equalization is achievable.
Hoods and Seals
To achieve the best seal, the mask skirt should be fitted directly onto
the skin of the diver’s face (Figure 13). Do not attempt to seal over or
against a neoprene hood as this will result
in leaking, excessive air consumption,
and hood inflation. A neoprene hood can
be trimmed to allow for the mask to seal
properly against the face.
For dry suits that have latex seals, the
mask may be worn directly over the hood.
This type of hood allows for the mask to
seal properly over the hood and the hood
seals to the face.
