REMOVAL OF HOSES FROM FIRST STAGE
WARNING: Purge all pressure from the first stage before attempting hose removal and
remove from the SCUBA cylinder.
Loosen and remove the hose by turning it in the counterclockwise direction with an open-
end wrench of the appropriate size. For a LP hose use a 3/8 open-end wrench and for an
HP hose use a 7/16 open-end wrench.
Lightly lubricate the threads and O-Ring of the port plug with Christo-Lube MCG129
lubricant.
Thread the port plug clockwise into the port and tighten to a torque of 30 in-lbs. using a
4mm hex key.
Store the dried regulator in a clean bag or storage box, away from sunlight, excessive heat
and humidity.
REGULATOR SECOND STAGES
The second stage of the regulator assembly receives breathing air at an intermediate
pressure of approximately 140 psi from the first stage and delivers it to you at ambient
pressure during inhalation.
When you stop inhaling, the second stage regulator shuts off the flow of breathing air and
provides a path for exhaled air.
All second stage regulators have a level of sensitivity that can result in excess breathing air
being expelled in the water when the second stage is not in your mouth.
When this occurs, it is usually during entry into the water or when on the surface.
