Page 7: Electrical Connections
2.0 Installation Horizontal models: if heavy fittings are to be clamped to the end of an extended work tube they can increase the bending stress at the centre of the tube. Support such fittings in such a way that expansion of the tube is allowed. If a metal work tube is being used in the furnace, ensure that it is earthed. - Page 8 2.0 Installation Products with a factory fitted supply cable are designed to be wired directly to an isolator or fitted with a line plug. Products without a factory fitted supply cable: require a permanent connection to a fused and isolated supply should be made to the internal terminals after temporary removal of the product's electrical access panel.
