How do I lower the pressure on my Potterton Suprima 50?

The pressure is to high and therefore cuts out the boiler.

you need to locate the pressure relief valve in the boiler isolate power supply then find the pipe leading outside follow back to prv gently turn the top or pull lever the pressure will fall set pressure to 1-1.5 bar
