Pressure release plug

To open the housing, the pressure

release plug must be first unscrewed and

then

pulled

out

(Counter-clockwise)

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.

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.

4.4

Special note on responsibility for watertight integrity:

Each housing is individually inspected and hydrostatically tested in the factory. The design of the

main piston O-ring seal is among the most reliable in the industry and the watertight integrity is excellent. This

special O-ring design provides a perfect seal even if there is any movement between the body and lid due to

change of ambient pressure. However please note that responsibility for ensuring the integrity of the

watertight seal lies entirely with the user. 10 BAR accepts no liability for damage to, or loss of any equipment

used with, or placed inside the housing. Users are highly recommended to carry out in-water test of the

all

the

way

(Fig

1).
