6.1 Over-Temperature Protection
The Koehler K430X2 Dual Twin Foaming Test
Bath is equipped with Over-temperature Protection
(OTP) circuitry, which prevents the unit from
exceeding unsafe operating temperatures. If the
unit cannot maintain the set point temperature and
begins to decline, the OTP circuitry may have
been activated. Please follow these steps.
1. Turn off the unit power switch and disconnect
the line cord.
2. Determine the source of the problem and
correct the situation.
3. Restart the unit. Monitor the operations to
ensure that the unit is operating properly. If
you are still experiencing trouble, please
contact
Koehler
technical
service
for
assistance.
6.2 Over-Power Protection
The Koehler K430X2 Dual Twin Foaming Test
Bath is equipped with Over-power Protection
circuitry, which prevents the unit from unsafe
electrical conditions. If power to the unit is lost,
then turn off the main power and turn it back on
again. The main power switch also functions as a
circuit breaker.
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, then please do
not hesitate to contact the Koehler technical
service department.
7.1 Routine Maintenance
The K430X2 Dual Twin Foaming Test 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.
