How to fill loop on greenstar heatslave ll external

[Dlowe81]

Hi, I’m trying to locate the filling loop on my combi boiler. There isn’t much info in the manual, just your installer will inform you where to find the filling loop which they didn’t. Any advice would be appreciated, I’ve attached some photos.

Thank you, found it totally separate to the boiler which I wasn’t expecting.
