2. Overtemperature cut-out, DB-3A only
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.
