Tuttnauer EA - Indicator Light Description; Pressure Gauge

1.5 INDICATOR LIGHT DESCRIPTION
PROGRAM Shows the selected programme (1,2,3,4).
START Shows the system is running a programme (11).
HEAT The system is in the HEATING stage. The indicator flashes
during the STANDBY- low power heating to keep the chamber hot.
STE The system ts in the STERILIZATION stage
EXH The system is in the EXHAUST stage
DRY The system is in the DRYING stage
FAIL The system has failed as the result of either a protective cutoff,
or the STOP key was depressed. A message indicating the
nature of the failure will be displayed on the screen.
ADD WATER There is a shortage of water in the water reservoir.
DOOR CLOSED Indicates the door is closed.
NOTE: Due to the inherent elasticity of the door gasket, the close door indicator light
may be illuminated green before a complete seal is made between the door and the
chamber.
Therefore, in order to ensure that the door is fully sealed, when the green light has been
illuminated continue to tighten the door bolt until “ hand tight”. Do not over-tighten the
bolt as this may result in damage to the gasket.
Should the autoclave fail to reach sterilizing temperature / pressure, always check first
that the door is fully sealed. if not, tighten the door bolt further, as described above, until
a complete seal is made.
PRESSURE GAUGE
The pressure gauge is provided as a guide only. Should there be a power failure during the
© operation of the autoclave, the pressure gauge indicates to the operator that there is pressure
in the chamber. A deviation of + 0.2 Bar (3 psi) is normal.
