Barrel heaters, several models

Connection

Cable with ground connection.

Assembly

The barrel heater must be mounted the lower part of the barrel so that the entire contents of the barrel will be heated. To ensure optimal heat transmission, the tensioning device on the heater must be re-tensioned after the first use. The tensioning device adjustment should be regulary checked. Use gloves if the heater has been in operation. The barrel heater must not be used outside, in wet rooms or when not mounted on a barrel. The heater must be kept.

Thermostat

Thermostat can be adjusted with a screw driver using the scale as referenc. To access the thermostat, a rubber plug must be removed from the terminal box. The temperature on the scale shows the surface temperature of the barrel, not the temperature of the content in the barrel.

Thermal cut-off

The barrel heater features a device to prevent overheating and that disconnects the element if problems should arise related either to the regulating thermostat or heat transmission to the barrel. The thermal cut-off unit can be manually reset with a push button, located under a domed nut at the terminal box. Before resetting, the barrel heater must be cooled and its attachment to the barrel checked. If the barrel heater cannot be operated after resetting the heater, if must be inspected by an authorized electrician.

Safety

Parts of the barrel heater become hot during operation!
The barrel heater must not be used closer than one meter from inflammable material, including construction material. The barrel to be heated must be open for ventilation throughout the entire heating period. The barrel must also be positioned at a well ventilated location to avoid ignition.
