CAUTION: 
This analyzer is not intended to be used on a 
continuous basis. 
CAUTION: Do not store instrument or its sensors with solvents or 
products that contain solvents. 
CAUTION: Except for sensor and battery replacement
, this 
analyzer should only be opened and/or serviced  by authorized 
Bacharach personnel. Failure to comply may void the warranty. 
HAZARDOUS AREA WARNING: Th
is instrument has not been 
designed to be intrinsically safe  for use in areas classified as 
hazardous locations. For your safety, DO NOT
 use it in hazardous 
(classified) locations. 
CAUTION: Do not use flammable or combustible substances (like 
carburetor fluid used for cleaning the probe) near an open flame. 
CAUTION: When the instrument is used in an inefficient oil-fueled 
appliance where there is a high emission of soot, the probe’s 
sample filter may become clogged. Before every use confirm that 
the filter is clean and replace it with a new filter if necessary. 
To prevent soot intake and a clogged filter, a smoke test should be 
performed before operating under such conditions. This ensures 
that the furnace or boiler is burning at a level appropriate for the 
use of this instrument. 
When the CO
2
  level exceeds the allowable threshold, a warning 
will prompt the user to consider performing a smoke test. This 
screen is cleared by pressing the ENTER button. Once the warning 
is cleared, it will not be displayed again for that particular test. If a 
new test is started (by pressing the HOLD button), the warning will 
be displayed again if the limit has been exceeded. 
IMPORTANT: Never disconnect the probe  from the instrument 
until purging is complete. Otherwise, leftover target gas (for 
example, CO) 
may remain in the probe and cause inaccurate 
zeroing  at power up 
that could lead to inaccurate gas 
measurements afterwards.
