Installation of the heating element unit
WARNING! The device must not be connected to electricity during installation.
Unlug the device prior to installation.
1. In case of a radiator connected to the central heating system, close both valves and
remove the heating agent.
2. Insert the heating element (1) into the threaded opening in the tee piece, lockshield
valve integrated with tee piece or directly into the radiator, depending on the
required connection type.
3. Twist the head of the heating element using a spanner no 24.
4. Position the element in such a way so that the indent in the head connection (A) was
directed towards you or sideways.
5. Open the valves, fill the radiator with the heating agent from the installation and
bleed it.
6. Make sure that the connection between the radiator and the heating element unit is
tight.
7. Install the controller – fit the indents on the head (A) with the indents in the control-
ler (B).
8. Position the controller casing in a way providing an easy and comfortable access.
WARNING! If you feel resistance when twisting the controller that means that you have
reached the maximum twisting span in that direction. Try to twist the controller in the
opposite direction. Any damage to the device will result in annulment of the warranty.
9. Secure the casing at the back with Allen key.
10. Close one of the valves before using the heating element unit and leave the other one
