Turbomax Plus 824E - water level

[laax]

Hi
I have inherited a Vaillant Turbomax 824E. Has been going well but I have no user manual and think I need to top up the water level. Hot water cools and heats up constantly when running and the level is now at zero. Can you advise how to top up the water level?
Thanks,

It has an inbuilt filling loop.

Underneath on the right front you will see two slotted valves. They do supply a fiddly key but a wide bladed screwdriver is better.

You have to turn both 90° clockwise looking up ( I think ) until the gauge reaches 1.5 Bar then close both the valves.

yep it's pretty straight fwd to fill up, as instructed above. Make sure you fill it up asap + then keep an eye on it......should always be at 1.5ish bars.

You can download the boiler instructions booklet, as a pdf i think, from the Vaillant website.
