that the Ozone Destructor Heater is on for 50% of the time,
which is typically 5 seconds on and 5 seconds off during normal

setting of 10%, which means that the Ozone Destructor Heater
is on for 10% of the time, which is typically 1 second on and 9
seconds off.

operation of the Ozone Destructor Heater, no system warnings
are generated.

the Ozone Destructor heater and the Cooler operates as
described in MAN PURGE CYCLE below.
MAN above, in MANUAL PURGE CYCLE setting, the first
parameter (2000 by default) defines the number of analysis
cycles the Ozone Destructor and the BioTector Cooler operates
as normal. The second parameter (15 by default) defines the
number of analysis cycles the Ozone Destructor heater is
switched off. The third parameter (15 by default) defines the
number of analysis cycles both the Ozone Destructor heater and
the Cooler are switched off.

AUTO above, in AUTOMATIC PURGE CYCLE setting, the first
parameter (15 by default) defines the number of analysis cycles
