Section 6 Maintenance
6.1 Cleaning the Instrument
The thermostat is a maintenance-free
instrument. To ensure reliable and precise
operation, it must be kept clean.
• Before cleaning the thermostat you should
switch it off, unplug the power cord and
allow the instrument to cool.
• Wipe the instrument with a soft, damp cloth.
Make sure that no water penetrates into the
instrument during cleaning!
If a cuvette overflows or bursts, or small
amounts of liquid are spilled, proceed as
follows:
• Switch off the thermostat, unplug the power
cord and allow the instrument to cool.
• Draw off the liquid with a pipette, avoiding
any contact with the skin.
DANGER
Caution should be exercised with acids and
lyes, as they can cause burns.
• Transfer liquid residues to an empty cuvette
for proper disposal.
• Remove broken glass with tweezers - avoid
any contact with the skin.
