EZ Solenoid Inline Shutoff
Product Description
EZ Solenoid Inline Shutoff
The EZ Solenoid Inline Shutoff gives the rebreather diver
positive control of the on-board oxygen supply when dealing
with ascents or with troubleshooting. Located near the oxygen
manual-addition valve, it also allows for easy connection of an
off-board oxygen source. Only one hose leaves the oxygen
cylinder and plugs into the manifold mounted to the oxygen
addition valve.
A Right-Angle Adapter (RG1350/RG1355) must be used to
route the solenoid hose up thru the slot in the frame with
oxygen manual-addition hose from the first stage. It is
suggested that the oxygen-regulator Over-Pressurization (OP)
valve be moved to the original position of the solenoid hose in
order to better protect it.
Installation
First-Stage Hoses, Over-Pressure Valve and Port-Plug
•
Using an 11/16 open-end (or similar) wrench, remove the
oxygen (green) low-pressure hose from the canister.
•
Using a 9/16 open-end wrench, remove the other end of
the hose at the oxygen-regulator first stage.
•
Using a 1/2-inch open-end wrench, remove the OP valve
from the oxygen-regulator first-stage.
•
Insert the OP valve in the hole where the low-pressure
hose was removed, and carefully tighten using a 1/2-inch
open-end wrench. Do not over-tighten.
•
Insert a port-plug (RG1245Black) in the hole where the OP
valve was removed, and carefully tighten using a 1/8-inch
Allen wrench. Do not over-tighten.
NOTE:
The rebreather should never be used without
the OP valve. It is an important piece of safety
equipment should the high-pressure seat of the first-
stage fail, causing a rupture of a hose and potential
injury.
Canister Right-Angle Adapter
•
Using an 11/16-inch wrench, remove the hose from the
oxygen-supply port at the bottom of the CO
2
absorbent
canister (if not already done).
•
Using an 11/16-inch wrench, carefully install a RG1350
Right-Angle Adapter (not included) to the oxygen-supply
port at the bottom of the absorbent canister and tighten.
Align the Adapter so the open-end is pointed inwards, or
towards the centerline of the rebreather. Do not over-
tighten the fitting.
•
Using an 11/16-inch wrench, carefully attach an HOLP28G
oxygen hose to the Right-Angle Adapter and tighten. Do
not over-tighten the fitting.
NOTE:
A hose with an in-line shutoff should not be
used in this application.
•
Route the hose through the slot in the frame and along the
right shoulder to the EZ Solenoid Inline Shutoff and attach
it, using a 9/16-inch wrench.
EZ Solenoid Inline Shutoff
• Remove the oxygen hose from the oxygen manual-
addition valve on the right counterlung.
•
Attach the EZ Solenoid Inline Shutoff to the oxygen
manual-addition valve.
•
Re-attach the oxygen hose to the open EZ Solenoid Inline
Shutoff port.
