7 Maintenance Procedure
WARNING.

voltages and/or temperatures which may result in
personal injury or death. If you have any questions
about maintaining your equipment, then please do
not hesitate to contact the Koehler technical
service department.
7.1
Routine Maintenance
The Rust Preventing Characteristics Bath
requires little routine maintenance to provide many
years of continuous service. However, over the
course of time, some instrument parts may need
to be replaced. When ordering replacement
part(s), please provide the model number, serial
number, and product shipment date of your
equipment so that we can ensure you will receive
the proper replacement part(s).
7.2
Bath Cleaning
To clean the instrument’s exterior, which
includes all painted surfaces and glass, either
a solution of soap and water or laboratory
grade detergent may be used.
Apply cleaner to clean wipe or cloth, not to the
instrument directly. Wipe surface clean.
Do Not
clean bath exterior with organic
chemicals such as Acetone, Toluene, Hexane,
etc.
For more difficult cleaning of finished surfaces,
a dilute solution or isopropanol in water may
be used.
It is not recommended that more aggressive
solvents be used on painted surfaces since
paint color will tarnish or be stripped from the
instrument.
Glass surfaces may be cleaned using a more
aggressive solvent such as acetone, if
necessary.
SHOCK AND BURN HAZARD:
Only clean
inside the bath when equipment is de-energized
and unplugged from the mains power supply.
Allow adequate time for heating coils to completely
cool before cleaning.
