Page 4: Purpose
PURPOSE Duct heaters are designed for heating of intake fresh air transported through the ventilating system. The unit is a component part and is not designed for independent operation. The heater is designed for extended periods of continuous operation without disconnection from the power mains. Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials, coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust, pathogenic germs). -

Page 12: Mounting And Set-Up
MOUNTING AND SET-UP READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT. Disconnect the unit from power supply prior to any connection, servicing and repair operations. Prior to the heater installation check the heater for the integrity and reliability of the heating element fixation. The heater shall be installed in the air duct with the same diameter (dimensions). - Page 13 CONNECTING ROUND AIR DUCTS TO THE HEATER The heater is designed for internal installation into air ducts in the horizontal or vertical position. In a horizontal position the connection box must face upwards. Permitted deviation up to 90 °C. The heater must not be mounted with the connection box suspended downwards (risk of condensate leaking and short circuit of power grid).
