Technical data
Alternative bracket location
General
The ambient temperature must not exceed 30 °C.
Cables and pipes must be laid so that it is possible to remove
the front plate and open the roof plate for service. For installa-
tion and accessibility for service, there must be at least 60 cm
space above and in front of the cartridge.
The electric cartridge is not designed for oxygenated water.
No work must take place on the electric cartridge's facing
plates.
Water quality
Tap water is usually classified from the point of view of hygiene.
Good water classified on this basis is not automatically suitable
for a heating system. To avoid problems a technical water analysis
should take place. Any nonconformities with standard values
should be corrected.
If the volume of the heating system is low, it can be filled with
water that was not classified as good system water. When the
water is heated, some oxygen and carbonic acid are emitted to the
expansion tank or vent valves. The remainder will react with the
metals in the system. This corrosion is often insignificant as the
same volume of water circulates and it soon becomes oxygen-free.
The system must be leakproof so that the water does not need
to be replaced with new oxygen-rich water and the water is not
oxygenated during installation.
Water quality, in respect of suitable tap water:
The alkalinity should exceed 60 mg/l to avoid corrosion.
Contents of carbonic acid over 25 mg/l increase the risk of
corrosion.
Sulphate contents over 100 mg/l may accelerate corrosion.
If the sulphate content is higher than the alkalinity, there is
a risk of copper corrosion.
Hard water causes boiler scale and is not suitable in a heating
system.
Very soft water may cause corrosion damage.
Chloride contents over 100 mg/l make the water aggressive,
in particular with lime deposits.
Low pH values may cause corrosion damage. The pH value
should be 7.5-8.5.
The incidence of carbonic acid in combination with low pH
and hardness values makes the water aggressive.
