tions through the nose
before
lifting the bottom of the mask frame and
to
continue exhaling until
the frame returns to the face.
The face forward position, increasing pressure (from exhaling) and purge
assembly on the pod all work together to drain the water from both cavities
of the mask. When air bubbles are seen escaping from the dewatering/
purge valve, the pod has been cleared.

1.
Exhale through the nose (with mouthpiece in your mouth) or mouth
closed.
2. In a face forward position lift bottom of lens frame away from face
Mask Clearing with Tilt to Purge Assembly
If using a pod fitted with the Tilt to Purge assembly this process is ac-
complished in the same manner as mentioned above, but will also require
another hand to activate the tilt to purge valve. Pressing on the Valve Stem
in any direction will active the valve. When air bubbles are seen escaping
from the dewatering/purge valve, the mask has been cleared.
Dewatering Basics
The same concept of clearing the mask applies to dewatering the pod.
Increased pressure, by exhaling through the nose, is the force that pushes
water through the water dump/ purge valve to clear the pod. When air
bubbles are seen escaping from the valve, the mask has been cleared.
Hands Free
When using the SuperMask
®
with the KMDSI Balanced SCUBA Regulator,
dewatering the lower cavity is an effortless process that is hands free. The
purge tube, located at the base of the pod Frame, houses a dewater/one-
way valve. This valve keeps water out and with an increase of cavity pres-
sure, by exhaling through the nose with the mouthpiece in your mouth or
mouth closed, it allows water to be forced out of the lower section of the
pod. Additional methods for dewater are also possible. Such as activating
the purge on the regulator and having the mouth closed and mouthpiece
out of the mouth.
Tilt to Purge
When using a pod with a demand regulator other than the KMDSI Balanced
SCUBA Regulator your hand will be required to activate the tilt to purge
found at the base of the pod frame.
