9 Filling and venting the boiler and installation
The central heating installation needs to be lled with potable water. For lling or topping
up the installation you use the lling loop according to the following procedure:
1 Switch on the power supply;
2 The diplay will show FILL;
3 All functions o (heating, DHW and pump);
4 Push briey the 'STEP'-button: P x.x = water pressure in bar;
5 Open the lling loop (Indication on display increases);
6 Fill up slowly to 1.5 to 1.7 bar;
7 STOP appears on the display;
8 Close the lling loop;
9 De-aerate the complete installation, start at the lowest point;
10 Check the water pressure and if necessary top it up;
11 Close the lling loop;
12 Activate the functions in use (heating
, DHW and/or pump );
13 If A xx appears on the display, wait for 17 minutes;
14 Check the water pressure and if necessary top it up to 1,5 to 1,7 bar
15 Close the lling loop;
16 Press the ‘STEP’-button;
17 Be sure that the lling loop is closed.
18 After the automatic de-aeration programm (A xx) is nished the boiler will return to
the Good state or Technical read out.
Check the water pressure regularly and top up the installation when necessary.
The working pressure of the installation should be between 1.5 and 1.7 bar when the
installation is cold.
It can take a while before all air has disappeared from a lled installation.
Especially in the rst week noises may be heard which indicate the presence
of air. The automatic air vent in the boiler will make this air disappear, which
means the water pressure can reduce during this period and therefore topping
up with water will have to be done.
