Safety System
Thermostat
Independent electronic circuit; thermal cutoff shuts the
heater OFF to ensure hose end air remains below 53°C
(53°C ± 3°C typical); back-up over-temperature detection
at hose inlet.

temp indicator light flashes, alarm sounds, heater and fan
shut down, operating indicator lights turn OFF, control
panel becomes unresponsive.
Fault
Fault information will display on the LCD, alarm sounds.
Over current protection
Dual input fused lines.
