4.3.4.5 Aeration Phase and Aeration Only Cycle
A catalyst within the QUBE converts the Hydrogen Peroxide (H
2
O
2
) Vapour into
Water Vapour and Oxygen.
An ‘Aeration only’ cycle can be loaded and run just like a complete cycle. This
cycle only runs the aeration phase. It ought to be run if the QUBE has alarmed
mid cycle and the Hydrogen Peroxide requires removing.
4.3.4.6 End of cycle
On completion of Aeration the Operator is prompted to confirm the end of the
cycle. At the end of a successful cycle, i.e. the Hydrogen Peroxide concentration
is below the preset level (a preset cycle parameter) the replaces the
and is visible on any page (as shown on the Information Page below). The
Hydrogen Peroxide level in the chamber should be checked periodically at the end
of the cycle by an independent low level Hydrogen Peroxide measuring device.
There is a test point on the window to enable the sample to be taken. Note the
concentration level indicated on the screen will be higher than a low level
measurement due to the lag on the sensor.
During this period the Aeration flow rate is cut back. This allows it to be left
running in this state for an extended period, for example over night, and ensures
there is no additional increase in chamber temperature.
