I just bled a radiator and now I can't get the system going because I don't know how to adjust the system pressure on the boiler.It has a digital display reading 0.0Bar.I don't have an instruction manual and I can't find anything on the net that would help.
Underneath the boiler it has three taps.Two red ones,one yellow.The one on the left has a Radiator icon with a down arrow beside it.The right had side one has the Radiator icon with an Up arrow beside it.
Any help would be gratefully appreciated.

You need to post a pic of under the boiler and your hotpress.
Other wise your looking for a steel braided flexible hose with a valve on it to repressure boiler it should be set at 1 bar

Nothing there of any use.
Take pic of hotpress and any valves in it

Hotpress? Surely the valves of the boiler itself are what need adjusting?

Robbie.G · 01-03-2014 4:09pm

The valves under the boiler just close off the boiler the red ones are water and the yellow is gas all they do is open and close and have no bearing on pressure whatsoever

The steel flexible hose marked with black line needs to be connected to the two silver coloured valves marked red.
Disconnect the blanking caps on the two silver valves then connect the steel hose to these then open silver valve on right the one with the black knob on it and fill heating to 1bar when done and finished disconnect everything in reverse order.
If your not confident undoing this yourself call in a plumber.
Hope this had been of some help to you

Thanks Robbie.I'm going to try that now.Get back to you later.Appreciate the advice.

Sorry to bother you again Robbie.Just wondering if I need to switch off anything before I attempt this?

Robbie.G · 01-03-2014 5:01pm

Just make sure the black knob on the silver valve is off.When you open the blank cap you could a little bit of water very slight any more than that and there's a problem
