Safety System
 Independent electronic circuit; thermal cutoff shuts the
heater OFF to ensure hose end air remains below 56°C
(53°C ± 3°C typical); back-up over-temperature detection
at hose inlet.

temp indicator light flashes, alarm sounds, heater and
blower shut down, operating indicator lights turn OFF,
control panel becomes unresponsive.
Fault: amber Fault indicator light flashes, alarm sounds.
