Hallo,

I've mount an ICS 40 ( EVM pilot and pilot external connection on hot gas pipe) on suction line of ammonia pumped system. I want to use it for defrost cycle.

Maybe it is not the happiest solution ( I think PMLX would be better) but I've done it.

I've start up the plant and, after defrost the ICS can't open.

I think the reason are:

- dirty into the pipe
- the hot gas is not enaugh for opening the ICS

What are your opinion about it?
