is made easier by the exhaled gas higher
temperature; moreover, two exhaust
valves, each one having a membrane,
are provided to allow the emptying of the
canister even during the dive. The canister
plug with bayonet coupling is furnished
with an o-ring washer that warrants a
perfect sealing.
If the canister is not used for long periods,
the plug could become hard to open and
more effort would be necessary, but this is normal as it is due to a stronger o-ring friction.
Note:always verify the integrity and the clearness of the o-ring washer on the closing plug as
it could show signs of filtering material dust. Also always check that the o-ring is correctly
positioned.
7) USER AND MAINTENANCE GUIDEBOOK
Each underwater breathing apparatus is delivered with the present producer information
guidebook and a warranty as well as an user and maintenance guidebook that should be
carefully read by the user. The warranty must be filled in and sent to the producer for validation;
the producer declares no responsibility in case the user does not respect instruction given in
the forementioned guidebooks, or for the incorrect use and maintenance of the product and its
parts.
The user and maintenance guidebook and the present information leaflet integrate but in no case
substitute a proper diving course held by qualified trainers.
Note: in case your underwater breathing apparatus has been delivered without an user and
maintenance guidebook, please request it before using our product.
8) INTEGRATED ALTERNATE SOURCE
The use of the underwater breathing apparatus TIR/
SPACE does not exclude the presence of an open
circuit alternate air source, as it can be chosen by the
user. It can be connected to the main pressure reducer
or a traditional open circuit regulator connected to the
second valve can be used.
In the first case, if the tank has a single connection,
to connect to the main pressure reducer the second
stage should be a balance power-assisted type as the
“OXIGEN and K50”model available on request (optional); in the second case, having two
connections valves (preferably) a traditional open circuit regulator could be connected to
the second valve, however it would be better to use a specific balance power-assisted Nitrox
model.
Note: before diving, always and carefully verify that no loss of gas occurs through the
connections to the valves and that the second stage is not free flowing; in both cases the
estimate
endurance is reduced
.
