3. Set up Instructions

3.1Pressure release plug: The body and lid are designed with a “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. To open the housing, the pressure release plug must be first unscrewed and then pulled out all the way. 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.

Important! Before diving, make sure the pressure release plug is pushed closed, and then screwed home, do not over tighten this plug (finger tight only).

The universal tool can be used for loosening this plug, in case it was over tightened.

3.2 Opening levers: After unscrewing and pulling out the pressure release plug, the lid can be opened. To overcome the friction of opening, two levers are used to push against the lid with a cam action. On some

models these opening levers are bolted to the body. On the other models, they are detachable levers, 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 two holes on opposite corner edges for opening. Gently lever off the lid with the supplied cams taking care not to twist the lid excessively. The lid should be opened keeping it approximately paralleled to the body at all times. If using a single lever, turn first one side 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.
