Re-inspect o-rings on end-cap and on the water trap for debris and

damage. Verify that the water trap is properly installed into the end-

cap. Lubricate the canister o-ring surface. Place the end-cap assembly

onto the open end of the center tube and rotate until the cap slips into

place. Rotate the end cap clockwise until the arrow on the end-cap

lines up with the locked indication on the center tube. Secure the

assembled canister to the top of the mounting plate using the elastic strap. It is necessary to stretch

the strap in order to thread the buckle. The strap should be pulled tight enough to prevent the

canister from sliding.

D S V

The DSV comes from the factory with the mushroom valves installed and the DSV attached to the

hoses. The diver needs to install a mouthpiece on the DSV. The mouthpiece is fitted over the

opening on the DSV and secured in place with the supplied wire tie.

Part of the normal pre-dive inspection is to insure that the directional mushroom valves are

operating correctly (Failure of either mushroom valve must be corrected before diving) but

periodic visual inspection is highly recommended. The valves are accessed by loosening the hose

clamps and removing the hose. The valves can now be removed for inspection an/or replacement.

IMPORTANT, the valves are directional, proper positioning must be observed. Gas must flow

from the diver’s left to the diver’s right, the gas flow direction is indicated by an arrow inscribed

across the length of the DSV. The hose connected on the inhalation side must be the long hose

with the RED connector.
