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
