Behaviour in the event of an emergency

Switch the device off.
In an emergency, disconnect the device from the mains feed-in: Hold onto the mains plug while pulling the power cable out of the mains socket.
Do not reconnect a defective device to the mains.

Overheating protection
The device is provided with a safety thermostat which is activated by overheating of the device (when exceeding the operating temperature). Investigate the cause of overheating. If the safety thermostat does not switch in the event of overheating, the overheating protection will be tripped. In that case the device switches off completely. If so, please contact the customer service to have the overheating protection replaced.

Tilt protection
The device comes equipped with a tilt protection. The tilt protection is a safety device intended to minimize the risk of fire in case the device is tipped over inadvertently. The device will be switched off when knocked over (or if its upright position is changed in any other manner). The tilt protection switches the device off when it is inclined out of its vertical position. The device can again be used as usual only a few seconds after placing it back in vertical position and on solid ground.

Information about the device

Device description
The oil-filled radiator TRH 28 E is used to generate warm air for interior spaces. The TRH 28 E comes with 3 power levels of up to 2,500 W. The heat electrically generated by the heating elements within the device is absorbed by the heating medium oil. The heating medium oil offers the advantages of quick heat-up and long-term heat storage capacity. On these grounds the heating medium oil can guarantee a continuous heat emission. The radiator’s 11 fins increase the heat radiating surface and so enhance its effectiveness. A target temperature can be set with the thermostat-controlled automatic operation. Once the target temperature is reached, the device switches off automatically. A 24-hour timer function and a digital control panel with LED display ensure convenient use. The device is further equipped with an overheating protection and a tilt protection.
