at an early stage such that intervention is possible in the event of a scrubber breakthrough or
loss of make up oxygen supply.
1.7.4 From the volume tank the gas is supplied to the conventional bell supply manifold in
the dive control.
1.7.5 In case of malfunction or failure of any pressure gauge, valve or regulator in the
Gasmizer System, the diver should be taken off the Gasmizer System and put on one of the
back-up supply systems described above while repairs are undertaken.
1.7.6 Reclaim diving should not take place with pressure gauges isolated or regulators
manually bypassed.
1.8 Control Console
1.8.1 The control console allows the entire Electric Gasmizer system to be monitored and
operated from dive control. It can be split into four separate sections.
1. THE BOOSTER PANEL gives a remote start/stop capability for the gas booster as
well as indicator lights to show the Booster Status.
2. THE OXYGEN PANEL allows control of the make up of metabolic oxygen i.e.
replaces the oxygen which the diver uses.
3. THE CONTROL PANEL allows control of the back pressure in the exhaust
umbilical.
4. THE MAKE UP PANEL allows control of the pressure at which the make up gas
supply begins flowing to replenish any loss of gas in the system. It also contains a
means of rapid oxygen injection for changing the gas mix.
NOTE
Rapid Oxygen Injection must not be carried out whilst divers are using the system.
