1. Introduction

10BAR Underwater Housings are small, light and rugged enough to be used on every dive. Use of a
clear polycarbonate allows for visual inspection of camera condition and the O-ring seal. 10BAR
Housings are designed for the ever -increasing variety of models of digital still and video cameras.
Advanced computer aided design and CNC manufacturing technologies ensure precise dimensions. Each
housing body is first injection molded, and then machined to configure to individual camera model. A
range of lens ports and controls are fitted, to tailor the housing to your camera model.

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.
