4.1 Air Lock:
The body and lid are designed with the Air Lock system "no clip" closure arrangement.
Testing has shown that this arrangement allow the water to exert an even pressure on the O-
ring, increasing the reliability of the watertight seal.
4.2 Pressure release plug
To open the housing, the pressure release plug must be first unscrewed and then
pulled out all the way (Fig 1). This provides a passage for the air to pass though and
eliminate the pressure different between the inside of the housing and the ambient.
The plug consists of an internal double O-ring seal on the stainless steel slide shaft.
These internal O-rings form the watertight seal. There is also a large outer O -ring under the
knob. This O-ring serves to prevent contamination of the slide shaft, with dirt, salt etc., and is
not required for watertight integrity. If this O-ring should become detached, it can simply be
pushed back in place.
