Ariterm Biomatic+ 20 - Water Piping and Filling; Planning and Installation Requirements

ARITERM SWEDEN AB Installation, Operation & Maintenance - 2009.02.18- 9/32
Planning and installation
Planning and installation shall be carried out in a professional manner, attention being
paid to general and local rules and regulations. Operating pressure is max. 1,5 bar.
Before taking the installation into service, and always at the beginning of the heating
season, the following checks shall be carried out:
that the heating system is lled and bled
•
that the circulation pump is working
•
that the system valves are open
•
that the automatic control and safety devices are in working order
•
that the chimney has the necessary draught and that the fresh air ventilation
•
is open.
Safety valve
If a closed expansion vessel has been installed in the radiator system, the safety valve
must be checked 4 times a year. Activate the valve by pressing or turning the control
button and check that water escapes from the overow pipe connecting the valve to
the drain.
Elecktrical installation
e connection is made in accordance with the wiring diagram annexed to this ma-
nual. Also the use of a safety switch (burner switch) is recommended. e other con-
nection cable delivered with the burner is for boiler temperature and ue gas sensors.
Work on the burner may only be carried out by a qualied serviceman. Make sure to
cut the power supply to the burner before servicing.
Before you begin heating, the heating system must be lled with water.
To fill the system, do as follows:
Open all shut-o valves, including the shunt valve. e pump must be switched
1.
o.
Fill the boiler and the radiator system with water. Bleed the system at the radia-
2.
tors.
Once the system is lled completely, the circulation pump can be started and
3.
heating can begin.
When the boiler water has reached its pre-set operating temperature, the pump
4.
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 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 tted with a factory wired 3-phase
6/9 kW electric heating element. e power of electric heating elements can be ad-
justed in service menu.
