SAFETY SYSTEMS
Dual temperature limit thermostats
Either of two independent 53
o
C self-resetting thermostats removes
power from the CWS4000 if the delivered air exceeds a preset limit
temperature.
Heater temperature limit devices
A 98
o
C thermal fuse and 104
o
C self-resetting thermostat protect the
filter from excessive temperatures.
Temperature limit alarm
Continuous temperature monitoring guarantees that the temperature of
the delivered air maintains its specified accuracy.
Control system failure alarm
Continuous self-monitoring by the control system ensures that it always
functions predictably.
