Page 13: Operator Safety
4.0 Operation Operator Safety The ceramic materials used in the product manufacture become electrically conductive to some extent at high temperatures. DO NOT use any conductive tools within the product without isolating it. If a metal work tube is used, it must be earthed (grounded). Switch off the heater switch whenever loading or unloading the product. -
Page 14: Power Adjustment
4.0 Operation It is recommended that a pressure relief system should be used to avoid an over pressurisation of the work tube. Please note: A product should not be heated up if any valves that have been fitted are closed to create a sealed volume. A sealed work tube should not be heated from cold due to the pressure increase caused by the trapped air or gas expanding during the heating process. -
