2.0 Installation Depending on the application of the product, it may be appropriate to position it under an extraction hood. Ensure the extraction hood is switched on during use. Ensure that the product is placed in such a way that it can be quickly switched off or disconnected from the electrical supply. -
Page 7: Electrical Connections
2.0 Installation If the product is to be used to heat substances that emit fumes, a fume extraction duct of approximately 75 mm - 150 mm inlet diameter may be placed directly above the chimney outlet. Do not make a sealed connection to the product chimney as this causes excessive airflow through the chamber and results in poor temperature uniformity. -
Page 8: Voltage And Power Limit
2.0 Installation Products without a factory fitted supply cable require a permanent connection to a fused and isolated supply. The product's electrical access panel should be temporarily removed, and connections made to the internal terminals. If the product is to be connected by line plug. The plug should be within reach of the operator and should be easy to remove. -
