Risk in the event of deviating value
pH value
Between 7.5 pH and 8.5 pH Lower values can result in corrosion damag
Alkalinity
At least 60 mg/l
Corrosion.
Carbonic acid content Max. 25 mg/l
Corrosion.
Sulphate content
Max. 100 mg/l
Corrosion. If the sulphate content is higher
than the chloride content, copper corrosio
may occur.
Chloride levels
Max. 100 mg/l
Corrosion. The aggressiveness of the chlor
increases in combination with the presence
lime deposits.

Install the boiler and the outdoor sensor
Install the boiler
Install the boiler with pipe connections downwards and in an indoor location that
is adapted for handling liquids. Leave at least 40 cm of free space beneath the boiler
so that the immersion heater can be replaced if necessary.
Install the outdoor sensor
Connect the outdoor sensor to the boiler using a cable with a cross section of at least
0.5 mm2 and a maximum length of 30 metres.
Position the outdoor sensor:
-
Halfway up an outside wall.
-
In a corner facing north or northwest.
-
So that the outdoor sensor is not affected by escaping hot air from vents, doors
or windows.
-
So that the outdoor sensor is not exposed to the morning sun.
To connect the outdoor sensor to the boiler, see the wiring diagram on page 23.
The boiler can be used without an outdoor sensor. In that case, the
boiler maintains a preset flow temperature and the heating curve’s
function cannot be used.
3.2.4.
Install the pipe system
Always use an internal support sleeve when connecting the boiler
to the pipe system, to ensure that the boiler’s internal pipe system is
not damaged.
Use max. 30% glycol in the system.
Use only glycol with corrosion-inhibiting additives.
