Hi,

I have boiler Vaillant VUW SOE 242_2-3 R2 (it's TurboBlock Pro).
Does somebody have service manual / maintenance PDF where can I get some additional informations?

Here's my problem:
I'm not sure at what bar should I pump the chaimber (pre-charge pressure at bars). When I turn on the hot water pump starts to work but it seems that there's some air in the pump cause the sound is very strage. How can i solve this problem so the pump should only circulate the water and not the air.
Second, I'm not sure when should i release the air from radiators - should the air be released while the boiler is working or while it's turned off?

Thank you in advance.
