6.7.1 Water treatment

In many cases, the boiler and central heating system can be filled with
normal tap water and water treatment will not be necessary.
Warning
Do not add chemical agents to the central heating water without
consulting Remeha. For example: antifreeze, water softeners, pH-
increasing or lowering agents, chemical additives and/or inhibitors.
Such agents can cause errors in the boiler and damage to the
heat exchanger.
Note
For untreated water, the pH value of the water in the installation
must be between 7 and 9 and for treated water between 7 and
8.5.
The maximum hardness of the water in the installation must be
between 0.5 and 20.0 °dH (dependent on the total heat output
generated).
More information is available in our Water quality regulations.
Always adhere to the instructions in the aforementioned docu­
ment.
6.7.2 Filling the siphon
Danger
The siphon must always be sufficiently filled with water. This pre­
vents flue gases from entering the room.
1. Remove the siphon.
2. Fill the siphon up with water.
3. Fit the siphon.
4. Check whether the siphon is firmly fitted in the boiler.
6.7.3 Filling the system
Caution
Before filling, open the valves on every radiator in the installation.
Note
In order to be able to read off the water pressure from the boiler
display, the boiler must be switched on.
1. Fill the central heating system with clean tap water.
Note
The recommended water pressure is between 1.5 and 2 bar.
2. Check the water-side connections for tightness.
