ARITERM SWEDEN AB Installation, Operation & Maintenance - 2007.08.14- 9/24
Before you begin heating, the heating system must be fi lled with water.
To fi ll the system, do as follows:
1 Open all shut-o valves, including the shunt valve.
e pump must be switched off .
2 Fill the boiler and the radiator system with water.
Bleed the system at the radiators.
3 Once the system is fi lled completely, the circulation pump can be started and
heating can begin.
4 When the boiler water has reached its pre-set operating temperature, the pump
should be stopped and the system bled at the radiators once again. is should be
repeated several times.
Remember that much air is enclosed in tap water. e enclosed air volume may reach
as much as 10%, which explains why bleeding takes time – especially where there are
large water volumes.
A closed system shall be fi lled until the pressure gauge indicates the correct system
pressure, i.e. the distance from the pressure gauge to the highest radiator in meter
times 0,1 which gives the system pressure in bar.
Adjust the red needle of the pressure gauge to the same value as the big needle.
Heating with electric heating element
Ariterm Biomatic+ 20 and Biomatic+ 30 has been fi tted with a factory wired 3-phase
