Operator Safety
This product incorporates a safety switch which interrupts the heating
element circuit when the furnace is opened. This prevents the operator
touching a live heating element and also prevents the product from
heating up if the furnace is left open. The operation of this switch should
be checked periodically.
Depending on use, the surfaces in the working chamber and the
chamber load may still be very hot after the appliance is switched off.
Touching these surfaces may cause burns. Use suitable personal
protective equipment or wait until the appliance cools down to ambient
temperature.
Before removing a hot object from the product, make sure there is a safe place to put it
down. If necessary use tongs, face masks and heat resistant gloves. Heat resistant
