Direct Electric Radiators KORALUX
KORALUX tubular radiators can be produced as independent direct-heating electric radiators. The radiators are fitted with an electric heater equipped with a temperature limiter and are filled with antifreeze. This enables their utilization in buildings where the temperature can be expected to drop to -10°C.
The electric heater is connected to the main distribution frame by a lead-in cable connected to the wiring box or the socket, if fitted with additional equipment the required comfort and economy levels are dependent on the following:
- the VS1 plug with manual control (order code Z-SKV-0002)
- the R10A electric temperature regulator (order code Z-SKV-0003)
The KORALUX direct-heating electric radiators can only be positioned vertically during installation and do not require either assembly or a safety pressure device for their operation.

Warning for your safety:
- The installation and replacement of the heating element, replacement of the power cable and fitting of all electric accessories may be carried out only by a person with the required and valid professional qualification.
- The recommended (maximum) heat output values of the electric heating elements mentioned in the technical data sheet of each individual towel rail radiator KORALUX may not be exceeded.
- If the same outlet is used both for connection of the radiator to the heating system and for the installation of the electric heating element it is necessary to order the “T-branch“ (article code Z-SKV-0001).
- The allowed working position is only vertical with the power cable below, that means the electric heating element may be inserted in the radiator only from below.
- The radiator may not be aerated and must be permanently connected to the heating system.
- Please study carefully the attached “Operating Instructions” where all principles and conditions of a safe operation of the radiator with combined heating are explained and highlighted clearly and demonstrably.
