1. Overtemperature cutout, DB-3D and DB-2TC

The overtemperature cut-out is a sensitive mechanical device and mechanical shock can cause it to trip.

• In the event of no heater power, check the mains plug and lead, then reset the cut-out control (located

at the rear of the unit).

• Repeated operation of the cut-out indicates a serious fault: you may need to return the unit to your

supplier for repair.

2. Fuses

Your unit is protected by two fuses. These should only be changed by suitably qualified personnel. If the

fuses blow persistently, a serious fault is indicated and you may need to return the unit to your supplier

for repair.
