3.0 Controls And Indicators
3.1 Dial Assembly
The manually operated dial is used to select the level of agent concentration from 1% to 18%. The dial is
marked at intervals of 1% from 1% to 10% and at intervals of 2% from 10% to 18%. Selections can be
made at any setting between 1% and 18%.
The dial release incorporated in the dial
assembly must be operated in order to turn
the dial from the
q
(Standby) setting and it
must be operated again to turn the dial from
12% to a higher % setting. All other
settings can be made without operating the
dial release.
A solenoid interlock mechanism is also
incorporated to help to ensure that the dial
can be operated only when the green
OPERATIONAL light located on the display
panel is illuminated.
