3.1
Operating Cycle
Switch on the electrical supply. The temperature controller will become illuminated and may now
be adjusted as described in section 4.0.
The furnace will begin to heat up. The output light on the controller will flash steadily at first and
then flash less as the furnace approaches the desired temperature.
To switch off power to the heating element, switch off or disconnect the supply.
3.2
General Operating Notes
Heating element life is shortened by use at temperatures close to maximum. Do not leave the
furnace at high temperature when not required. The maximum temperature is shown on the
furnace rating label and on the back page of this manual.
Materials such as waxes, case hardening compounds, melting fluxes and other reactive salts
readily penetrate the ceramic tube and attack the wire element, causing premature failure.
3.3
Operator Safety
The ceramic materials used in furnace manufacture become electrically conductive to some extent
at elevated temperatures. DO NOT use any conductive tools within the work tube without
isolating the furnace, unless the tools are earthed (grounded).
Avoid burns. Carbolite can supply tongs, face masks, and heat resistant gloves. Before you
remove a hot object from the furnace make sure you have a safe place to put it down.
