Set the exhaust valve for automatic buoyancy control

You can remain neutrally buoyant without manual deflation: when the exhaust valve is

correctly located (on the highest point of the suit) and properly set and when you are

correctly compensated with weights, When you adjust the setting by turning the valve

Cover a clicking sound will help you determine the fine tuning. When the valve is properly

set you will be able to fine tune the gas volume in the suit further by rolling the body or

by raising or low the elbow.

The valve may need further fine tuning during the dive depending on the duration of the

dive and the suit material:

During the dive

There should be no air in your BC during the dive. The BC is used as a back-up. Adjust

the valve little by little by turning the valve's cover.

For reduced buoyancy:

adjust counter clockwise

(towards —)

= lower pressure

= less air retained in the suit pressure

more air retained in the suit

During the ascent

During ascent or while changing depths during the dive, you can adjust the air volume

within the suit by rolling the body or by raising or lowering the elbow (provided the valve

is properly set and you are correctly weighted). When the exhaust valve is elevated, the

water pressure decrease and the spring loaded Piston will automatically open the valve

to deflate expanding air.

For slower ascent: raise the arm (with the exhaust valve)

The internal suit pressure will increase compared to the ambient water:

pressure = more air, deflated = decreased buoyancy.

At the surface

To maintain buoyancy and to preserve the insulating effects of the air, turn the valve

clockwise(towards+) to maintain optimal pressure inside the dry suit. Use your BC to

help to float.

Exhaust valves Maintenance

After each dive, especially if water contains silt and sand, flush the exhaust valve tho-

roughly with fresh water while turning the lid back and forth.

The exhaust valve cover/lid should always be adjusted clockwise to maximum + prior to

detachment from the suit and prior to re-attachment into the suit valve port.

Have the valve checked and served once a year by a qualified technician.

For increased buoyancy:

adjust clockwise

(towards +)

= higher pressure in the suit compared

to ambient water
