Use distilled water, or alternatively mild solvents such as
isopropanol to clean the flue gas analyzer. If using
isopropanol, please refer to the instruction leaflet for the
product. Isopropanol fumes have a slight narcotic effect,
and typically cause irritation of the eyes and sensitive
mucous membranes. When using it, please ensure that
there is adequate ventilation.
Do not store any objects that have come into contact with
solvents and/or degreasers (e.g. isopropanol) in the case.
Evaporating or leaking solvents and/or degreasers may
cause damage to the instrument and to the sensors.
The use of strong or harsh alcohol or brake cleaner can
result in damage to the instrument.

consent of the responsible approval authority, may cause the
