Agent Level Display

indicate the nominal volume of agent in the vaporizer sump.
The
symbol denotes a 390 ml volume of agent and the
symbol denotes a 60 ml volume of agent in the sump.
Fig. 6 Operational
As the sump fills, the first agent level indicating bar appears in the LCD volume display when there is
between 60 and 80 ml of agent in the sump. As the level increases more bars are displayed as illustrated on
Fig. 6 and as the level decreases less bars are displayed.
When the bars are either level with or below the
<
, the sump can accommodate 240 ml of agent, which is
one full bottle. When there are no bars visible, as illustrated on Fig. 7, the Low Agent Level alarm is
activated as described in Section 3.3.4.
Note: The agent level display is calibrated to be most accurate when the vaporizer is in a perfectly level
position. Deviations from a level position affect the accuracy of the agent level display and may activate the
LOW AGENT level alarm.
