Safety features
Overheat thermistor
A thermistor in the bath senses any over-temperature fault condition. If
such a condition occurs, all power is removed from the bath until an
operator resets the over-temperature limit circuit.
Thermistor detection/cutoff
If the control thermistor is disconnected, all power to the bath heaters is
cut off.
Liquid-level control float
Operation of the bath is not possible unless it is filled with liquid to a safe
operating level. A liquid-level control float prevents the control circuit
from heating the bath until the safe operating level is attained. The bath
heaters are automatically turned off if the bath liquid drops below the
minimum safe level.
Operator Safety
All technicians who use the CT-1000 should follow these basic safety
procedures:
Do not place the CT-1000 system on an unstable cart or stand. The
CT-1000 should be placed on a stable laboratory table or bench.
If any liquids are spilled into the electronic components of the CT-
1000, contact CANNON
®
Instrument Company immediately.
Do not position power cords so that they are likely to be walked on
or pinched by items placed on or against them. Keep all connections
as neat as possible.
If the CT-1000 will not be used for an extended period of time,
unplug the power cord from the wall outlet. To disconnect the power
cord, pull it out by the plug. Never pull the cord itself.
CAUTION
Do not attempt to service the CT-1000 system by removing panels and
trying to effect repairs. Contact CANNON
®
Instrument Company regard-
ing service and repair needs.
CAUTION
The bath fluid used with the CT-1000 may be dangerous. Use the proper
safety precautions when handling the bath fluid in use (refer to the
Material Safety Data Sheet included with the bath fluid for more detail.)
