4. Set up Instructions

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, Increase 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 (Counter-clockwise) (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.

(Fig. 1) Open Housing Procedure

4.3 Opening levers:

After unscrewing and pulling out the pressure release plug, the lid can be opened. To overcome
the friction of opening, use lever (Fig. 2) to push against the lid with a cam action. Be sure they are
inserted all the way flat to the housing before turning to avoid damaging the protrusions on the lid. The
body has four holes on each corner edges for opening. Gently lever off the lid with the supplied opening
lever (Fig. 3) taking care not to twist the lid excessively. The lid should be opened keeping it
approximately paralleled to the body at all times, turn first one corner a little, then the other a little, and
repeat again until the lid is opened. Remember to unscrew and pull out the pressure release plug all the
way first, otherwise the air pressure will resist attempts at opening. Lay the lid on a flat stable surface
after opening.
