Operating Instructions
2.7 First Stage Regulator
The first stage regulator used on the air supply bottle shall be a CE approved
high-flow unit such as the KMDSI SuperFlow® regulator. A submersible pressure
gauge shall be connected to the regulator to enable the diver to monitor the status
of his air supply.
The Super Flow® 1st Stage Regulator is Part # 305-161.
2.8 Overpressure Relief Valve
The first stage regulator must be fitted with a KMDSI High Flow Overpressure
Relief Valve ( Part # 200-017). This valve is included with the Balanced EXO and
must be installed in a low pressure port on the first stage regulator. The purpose
of this valve is to allow the regulator to bleed off excess pressure should the first
stage develop an internal leak. If the first stage leaks and this valve is not present,
the pressure between the first stage regulator and the second stage could increase
until the hose ruptures. This will cause a complete loss of the air supply. It could
also lead to injury of the diver due to the whipping action of the hose.
Part # 200-017, Overpressure Relief Valve
The KMDSI Overpressure Relief Valve
has been manufactured in two different
flow rates. The original valve had a
lower flow rate than the current valve.
The newer valve has been marked
in two ways, the first being a groove
around the flats of the hex. Currently
the valve is marked with a groove
around the top of the body. This is the
same valve, just different markings.
Do not use the older KMDSI Overpressure Valve Part #
200-015
. It does not have
the groove cut in the valve body.
B
CAUTION
The certified KMDSI first stage regulator used with the EXO-
26 MUST be equipped with a KMDSI High Flow overpressure
relief valve. In the event the first stage leaks there is no way
for the pressure in the hose attached to the second stage to
relieve itself. The hose may rupture, leading to a loss of air
supply and possible personal injury to the diver.
