Ferroli Optimax HE 31C Error 37f HELP

[vandacolgate]

Hi
I have the Ferroli Optimax HE 31C, and the display is reading Error 37f, I have looked this up and is down to the pressure being low, so im told.
Can somebody tell me how to adjust the pressure please
Ive been told its something to with the 2 Black 'taps' underneath.
but what do i do, undo them, then what, do them back up? or what
Help would be very gratefully received!!!
thanks

presume you mean the filling loop below with a chrome flexi hose between

you will note black levers across fittings ,move on into the open position by turning inline with fitting

then open other the same but slowly,you will hear water going into system,once gauge at 1.5 bar (when system cold,)close valve to closed position and then close the other valve to same closed position

yes you undo them 1/4 turn so that they are in line with the valve until the pressure is up to about 1-1.5 bar then close them again so that they are at right angles to the valves.

why not do it now will take a couple of minutes max to do

the boiler is in my new house, but im in the process of moving and am getting the new place up to scratch first.
also does it matter which one i open first?

no open them either way round doesn't matter. you will know which is off the mains you will hear the water going in when you get up to pressure just turn them off.
