Hi all - could someone tell me which way up a flow switch should be installed on one of these boilers, it doesn't have an impeller by the way more of a float that obviously falls one way or the other depending on how you tilt it ? I know what way I think it should be but the boiler doesn't work when it's in it's logical (my) position....

Thank you ecowarm I had looked at that but wasn't clear on which way I assumed the bit sticking out the top on the left was the cable - been told this morning that the arrow should be on top and obviously facing the right direction
