When determining the size of the emergency gas
cylinder to use, several factors must be considered.
The divers depth, the length of time the diver may be
without the main gas supply, and the gas consump-
tion rate. Regardless of the cylinder used, it should
be of sufficient volume to allow the diver to ascend
at a normal rate or transit to a point where a normal
gas supply can be reestablished.
European C.E. ONLY
WARNING
A standard SCUBA submersible pressure
gauge must be connected to the high
pressure port on the first stage so that
the diver can monitor their emergency
supply.
Use a good quality first stage for
your emergency gas supply.
In European countries that have adopted C.E. certi-
fication, only C.E. certified cylinders are allowed to
be used and must have a minimum charged capacity
available to the diver of 1400 N/l (50 scf). The emer-
gency gas supply must only be fitted with a KMDSI
first stage regulator and have a KMDSI over pressure
relief valve installed (Part # 200-017).
The relief must be adjusted to start lifting at ap-
proximately 20 p.s.i.g. (1.4 bar) above the regulator
intermediate setting. The purpose of the relief valve
is to allow pressure to vent off in the event the first
stage regulator develops a leak or creeps. Without a
pressure relief valve, the hose could rupture and the
emergency gas supply would be lost.
The emergency air/gas tank must be fitted with
a good quality first stage regulator to reduce the
pressure to less than 225 p.s.i.g. (16 bar) ambient
32
diver pressure. The KMDSI SuperFlow
SCUBA regulator (Part #305-161) is an excellent
device for this use.
These regulators reduce the tank pressure to ap-
proximately 145 p.s.i.g. (9.9 bar). Other quality high
performance Scuba regulators may also be used.
Connect the first stage hose with a set of quick dis-
connecting locking sleeves to the emergency valve
assembly located on the side block.
The first stage regulator must have at least two low

pressure ports. One port is used for the connector
hose to the emergency valve and the second is used to
install an overpressure relief valve (Part #200-017).
If the first stage develops a leak, the full pressure of
the tank could be placed on the low pressure hose.
This could cause the hose to burst. The overpressure
relief valve will bleed off any leak.
Make sure the emergency valve knob is turned off,
otherwise the emergency gas supply will be used up
without the diver's knowledge. Once the emergency
supply hose is connected, the tank valve is turned on
to pressurize the hose. In the event of an emergency
due to a loss of the main gas supply, the emergency
valve knob located on the side block is turned on
supplying gas to the side block assembly and the
regulator.
WARNING
Never dive without an over pressurization
relief valve installed on the EGS regulator
(1st stage). Without the relief valve if the
EGS regulator develops an internal leak, or
carries-away, the full pressure of the EGS
cylinder would be placed on the low-pres-
sure EGS hose and the Emergency Valve.
This could cause the low-pressure hose to
burst resulting in the complete loss of the
EGS system.
