Re: Cycling a/c or not?

The Old Air tech support guy told me I don't need a Trinary switch. I am running the clutch fan on my LS motor in the original truck shroud. The clutch cycling switch that is built into the POA update valve is all I need as long as high and low side pressures are correct. 150-250psi on the high side or 2.5 times ambient temperature, and 35-45 psi on the low side.

Re: Cycling a/c or not?

If your clutch fan is moving enough air across the condenser......He is correct.

And as long as you never get in a wreck, you don't need seatbelts..... But you never know. Personally, if it were me and I was putting together an A/C system that was anything other than a factory installed, completely stock set up, I would put h high pressure switch in it too.
