9 Maintenance
General maintenance
The IS20 instruments are “repair by replacement” units,
and the operator is therefore required to perform only a
very limited amount of preventive maintenance.
If the unit requires any form of cleaning, use fresh water
and a mild soap solution (not a detergent). It is important
to avoid using chemical cleaners and hydrocarbons such
as diesel, petrol etc.
Make sure that all open SimNet connectors are fitted
with a protection cap (part no. 2400655).
Always put on the weather cover when the unit is not in
use.
