7 Maintenance
WARNING: Disconnect power to the unit
before servicing to avoid exposure to high
voltages and/or temperatures which may result
in personal injury or death. If you have any
questions about maintaining your equipment,
please do not hesitate to contact the Koehler
technical service department.
NOTE: The bearings on the linear rail
are maintenance-free, lubrication-free. Do not
attempt to apply any lubricants to rail or
bearings. If sticking or slipping occurs, contact
the technical service department.
7.1 Routine Maintenance
The Koehler Water Separability Instrument
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. A drain is also
provided in the back of the unit to empty the
bath of medium.
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.
