Alpha sy9-24 low pressure

[bedek]

Hi,

I've turned of my gas boiler for a week and now it shows alert that pressure is to low (A and B blinks)

How can I re pressure Alpha sy9-24 gas boiler ?

In the instruction on page 15 there is information that I need to "Open the fill point valve on the filling loop until water is heard to flow" which is fine but do I have to connect that filling loop to the boiler ? if so then would that be ok to connect hose from the tap to the inlet marked red on the attachment ?

Regards,
Adam.

Thats a drain point on the boiler, you should look for a metal braided hose this connects to two pipe with maybe black handles

As I understand the metal hose you mentioning is the filling loop ? I so the in the instruction for the boiler there is information that it should be disconnected after filling the boiler - see "Screenshoot 1".


Later in the instruction there is information how the system should be filled - seen "Screenshoot 2".


My question is - if I buy such filling loop hose where should I connect it ? please find attached photos "boilder--..."


I can not add link to the full instruction as it is blocked on this forum 🙁

Have a look above the boiler, or under kitchen sink or in the airing cupboard.
