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 CO2absorbent
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.

Oxygen-Compatibility
Using oxygen-compatible materials and assembly processes that are todays’ industry standard, the EZ Solenoid Inline
Shutoff is suitable for 100% oxygen use.
Care and Maintenance
Your EZ Solenoid Inline Shutoff will provide you years of service with proper care and maintenance. As with the other
components of your O2Ptima rebreather, this involves post-dive care and regular professional service.
Note: Stainless steel can develop rust even when properly cared for.
Post-dive care: After use, thoroughly rinse the assembly in fresh water and allow it to thoroughly dry before storing it in a
closed container. Do not hang or store any regulator components in a manner that puts strain on the hoses. Dive Rite
recommends Salt-X for salt removal (www.salt-x.com).
Professional service: Over time, mineral deposits and salt build-up can accumulate on any component, which can
adversely affect performance. Professional cleaning and service is the only way to remove these deposits and return the
rcomponent to its proper working order.
To keep your rebreather working at its best performance, you should have the unit serviced at least once every year or
100 dives by a professionally trained technician.
Note: Avoid excessive pool use. Excessive use in chlorinated water can lead to premature discoloration and shorten the
products life.
Cautions
The EZ Solenoid Inline Shutoff adds one more potential failure point in the oxygen delivery system of the rebreather. You
MUST make sure that the EZ Solenoid Inline Shutoff remains open, unless you are trained and confident in diving your
rebreather manually. Be sure to include the EZ Solenoid Inline Shutoff in your pre-dive check.
If the EZ Solenoid Inline Shutoff is left closed and you fail to dive the rebreather manually, hypoxia and death can occur.
Note that the rebreather electronics will try to automatically activate the solenoid, but WILL NOT deliver oxygen at a fail-
safe 0.20 PO2because the solenoid's oxygen source will be closed by the EZ Solenoid Inline Shutoff.
Water intrusion to the solenoid oxygen-supply hoses may occur when using the EZ Solenoid Inline Shutoff to switch
between on-board and off-board gas sources while in the water. This could cause contamination to the solenoid and
possibly a solenoid malfunction.
To switch oxygen-supply sources, the following procedure should be followed: 1) Close the slide valve on the EZ Solenoid
Inline Shutoff, 2) Disconnect the current supply hose, 3) Attach new supply hose, 4) Operate the “manual-add” valve on
the Oxygen counterlung to clear any water from lines, 5) Open slide valve, 6) Verify that solenoid is working.
