CLEANING AND MAINTENANCE
Use a cloth dampened with mild soapy water to clean the housing and the surface of the
instrument.
Note
Do not use chlorine bleach or other chlorine-based cleaning products,
abrasive cleanser, ammonia, steel wool or cleaning products with
metallic components under any circumstances. These will damage the
finish of the instrument.
The instrument is maintenance-free. Should repairs become necessary, please contact an
authorised Heidolph Instruments repair technician. Please contact your Heidolph
Instruments dealer or a Heidolph Instruments representation for more information (see
page 43).
Caution
Unplug the AC power cord before opening the housing.
