NOTE
When you disconnect the first stage from the cylinder valve take care that water is not
allowed to enter the regulator, particularly via the filter.
5. Remove the regulator from the cylinder:
5.1. Yoke connection
a. Unscrew the yoke screw and disconnect the regulator from the cylinder.
b. Dry the dust cap with a towel or other lint-free cloth. While you may use air
from your tank valve to blow the water off the dust cap, you run the risk of blowing
water into the filter.
c. Place the dust cap over the regulator first stage inlet fitting and seal it securely in
place by tightening down the yoke screw.
d. With the cylinder valve facing away from you, open the valve slightly to release
a short burst of air, and then immediately close the valve. This will clear any
remaining dust or humidity that may have accidentally entered the valve. If available,
fit the cylinder valve protector to avoid the entry of any further dust or humidity.
5.2. DIN or EN 144-3 Connection
a. Remove the regulator from the cylinder valve by completely unscrewing the
DIN wheel.
b. Blow out any water inside the protector cap or wipe it out with a clean towel,
and wipe the threads of the regulator first stage connector clean and dry.
c. Install the cap over the threads of the regulator first stage connector.
d. Screw the DIN connection completely into the dust cap.
e. With the cylinder valve facing away from you, open the valve slightly to release
a short burst of air, and then immediately close the valve. This will clear any
remaining dust or humidity that may have accidentally entered the valve. If available,
fit the cylinder valve protector to avoid the entry of any further dust or humidity.
6. Wipe the regulator dry.
7. Undo the screws retaining the corrugated hose connectors to facilitate hose drying.
8. When the inside of the corrugated hoses is dry, refit the mouthpiece connectors tak-
ing care that the direction of gas flow indicated on the mouthpiece body and on the 2
stage housing is followed.
