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, 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 (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 onsists 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.

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.
