Maintenance
Check manometer 2 times/year
It is particularly important to check the manometer after a new installation. The manometer which shows the pressure within the radiator system should show
between 0.5 – 1.2 bar. If needed, fill the system with water until the manometer shows 1.0 bar. If you feel uncertain contact your installer.
Check safety valve 2 times/year
Exercise the safety valve by turning its wheel counter clockwise until water is streaming out of the valve. An overflow pipe shall be mounted that lead water
to the nearest floor drain. The reason for this is to secure the function of the valve and that it is not stuck. The temperature variations within the system make
the water expand which may lead to water dripping out of the overflow pipe. This is normal.
IMPORTANT!
The overflow pipe of the safety valve may never be blocked!
Cleaning the particle filter 2 times/year (optional)
When the tank has been installed the filter ball valve shall be cleaned once a week the first two
weeks. After that the interval is twice a year.
1. Shut the system down via the on/off button on the control panel. Then switch the control fuse off
2. Close the valve by turning the handle (a) 90° upwards and screw off the sealing lid (b).
3. Remove the locking ring (c) using lock ring nippers (e) and pick the filter ball valve out (d). Clean it
with water.
4. Assemble it all back in the reverse order.
5. Open the valve to its previous position (the handle to the side).
6. Restart the system by turning the control fuse on and then push the on/off button on the control panel.
Check the protective anode
1. Shut the system down via the on/off button on the control panel. Then switch the control fuse off.
2. Turn off the incoming fresh water to the tank (a).
3. Open a domestic water tap somewhere in the building, to release the pressure within the tank.
4. Remove the anode (b) from its position (at the upper flange) and perform a visual inspection of it.
5. Measure the diameter. If the diameter of the anode is less than 11 mm it shall be replaced.
A anode can be ordered from the installer.
6. Mount the anode back into the tank.
7. Close the domestic water tap.
8. Open incoming fresh water to the tank.
9. Restart the system by turning the control fuse on and then
10. push the on/off button on the control panel.
IMPORTANT!
Replace the anode if the diameter is less than 11 mm. The anode protects the tank from aggressive chemical substances in the water.
IMPORTANT!
If the power cord is damaged, it must be substituted either by the manufacturer, by its aftersales department or by qualified personnel, in order to
avoid any danger.
