Care and maintenance

This chapter describes the steps and action required in order to keep the product func-
tioning properly.
See also Regular care, p. 18.
I.1

Cleaning the measuring instrument

If the housing of the instrument is dirty, clean it with a damp cloth.
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 pro-
duct. 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 degrea-
sers (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.
