Filling the siphon
Danger
The siphon must always be sufficiently filled with water. This
prevents flue gases from entering the room.
1. Remove the siphon.
2. Fill the siphon with water up to the mark.
3. Fit the siphon.
Caution
Fit the vent hose above the siphon.
4. Check whether the siphon is firmly fitted in the boiler.
6.8.3
Filling the system with the automatic refill device
Caution
Before filling, open the valves on every radiator in the central
heating system.
The automatic refill device is placed under the boiler. This refill device can
fill an empty central heating system semi-automatically to the set
maximum water pressure. To do this, proceed as follows:
1. Switch on the boiler.
Caution
The automatic refill device is only active if the boiler is switched
on.
2. Check and adjust the following boiler settings if necessary:
2.1. The automatic refill device must be on AUTO.
2.2. The valves on the mounting frame must be open.
2.3. The automatic refill device is set for semi-automatic (manual)
refilling. By configuring parameter AP014, you can also select
automatic refilling or to switch off the refill device.
See
Refilling the system with the automatic refill device, page 111
Important
Semi-automatic refilling means: The boiler control panel
indicates that the system needs to be refilled and requests
confirmation from the user.
Automatic refilling means: The system is refilled as soon as the
water pressure is too low.
3. A message to indicate that automatic filling is necessary will appear
on the display:
3.1. Press the
button to confirm automatic filling.
Important
Filling can only be interrupted if the water pressure is higher than
the minimum water pressure.
4. A message will appear on the display when automatic filling is
complete:
4.1. Press the
key to go back to the main display.
5. Check the water-side connections for tightness.
