How to top up a Powermax 155

[Bluejeros]

Hi there,

I have a Powemax 155 that is running at around 0.5 Bar. I would like to top up the water but how? Referring to the hand book it says to connect the filling loop flexible hose to the mains supply and the other end to the valve on the radiator circuit. BUT the flexible hose is already connected at both ends, with a tap without a handle in the middle! Help! is this the right hose?

yes it is the right hose but it may have a slot instead of a handle which you need to turn with a screw driver through 90 degrees but make sure you turn it back to exactly where it was once the pressure has reached no more than 1.5 bar
