AFTER THE DIVE
NOTE: If fresh water is available, rinse your regulator completely
before depressurizing it, and thoroughly dry the first stage and
cylinder valve. This will help to prevent any contaminants from
entering the regulator when it is removed from the cylinder.
Removing the Regulator from the Cylinder Valve (Yoke
Connector)
1. Shut off the cylinder air supply by turning the cylinder valve
handwheel clockwise until it stops.
2. While observing the submersible pressure gauge, depress the
purge button of the second stage. When the gauge reads zero and
airflow cannot be heard from the second stage, release the purge
button.
3. Turn the yoke screw counterclockwise to loosen and remove the
first stage from the cylinder valve.
4. Dry the dust cap with a clean towel, or with low pressure air.
5. Place the dust cap over the first stage inlet fitting and seal it
securely in place by tightening down the yoke screw.
Removing the Regulator from the Cylinder Valve (DIN Connector)
1. Turn off the cylinder air supply by turning the cylinder valve
handwheel clockwise until it stops.
2. While observing the submersible pressure gauge, depress the
purge button of the second stage. When the gauge reads zero and
airflow cannot be heard from the second stage, release the purge
button.
3. Turn the first stage handwheel counterclockwise to loosen and
remove the first stage from the cylinder valve.
4. Blow out any water inside the protector cap or wipe it out with a
soft cloth, and wipe the threads of the first stage connector clean
and dry. Install the cap over the threads of the first stage
connector.
