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.
