Pressure Testing for R410a
Hi Folks
this question has come to light after a phone call yesterday from the Health & Safety Executive asking if we use a gauge manifold when pressure testing for R410a. Apparently an engineer has been killed when the glass window blew out of his manifold. My question is do people feed the pressure into the system to be tested through an R410a manifold or do you come straight of the nitrogen regulator?
Secondly how many engineers actually have a specific R410a manifold?
This is to give me an idea as to what is going on out in industry so we can make sure everybody knows how this procedure should be done for R410a. I have heard a couple of stories recently were engineers are pressure testing without a regulator, they come straight of the bottle and regulate the pressure with the gauge manifold valves.
Comments please
Ian
