Power Switches
Dust caps tted on the main power switch and zone
switches protect them from dust and the corrosive eect of
cooking fumes. If the dust caps are removed, or not replaced
following servicing, the switches will deteriorate and have
reduced life expectancy. Replace the dust caps following
servicing.
