quality or gas flow path environment due to the degradation of other system filters and
consumables.
NOTE: If using Nitrogen as Carrier Gas and therefore not using the Air
Scrubber Accessory, the “Soda Lime” status will still be useful for monitoring
the NDIR baseline to provide warnings in the event that the baseline goes
outside the expected limit.
The Air Scrubber Housing contains the Soda Lime and Activated Carbon consumables.
The Soda Lime removes CO
2
from the Carrier Gas Flow Path. The Activated Carbon
(also called Activated Charcoal) removes volatile organics from the Carrier Gas Flow
Path.
• Limit: > 0.2 x NDIR Upper Range in ppm and you will get the baseline warning
• Affected System Components:
► Air Scrubber, if using — For more information, see “Soda Lime and
Activated Carbon (Air Scrubber)” on page 195.
• Soda Lime
• Activated Carbon (also referred to as “Activated Charcoal”)
► Carrier Gas Source; if using Nitrogen as Carrier Gas.
Fan Filter
The “Fan Filter” status displays the average Internal Temperature of the Analyzer over the
last 24 hours, in °C. The Upper number on the gauge shows the current internal
temperature of the Analyzer and the lower number on the gauge is the 24 hour average.
An increase in average internal temperature could indicate that the Fan Filter media
needs to be cleaned or replaced.
• Affected System Components:
► Enclosure Fan Filter Media — For more information, see “Fan Filters” on
page 189.
Cartridge
The “Cartridge” status displays the Total Injected Volume* of sample that has been
injected into the Furnace (displayed as “Reactor”) in mL. The calculation is taken from the
last time the “Cartridge” maintenance was “Reset” on the Menu → Service →
Maintenance screen.
• Affected System Components:
► Furnace Cartridge; including Furnace Cartridge Packing. For more
information, see “Furnace Cartridge” on page 205.
