Hello to all,
I just have a few A/C questions. I'm changing to a rotary compressor and I need to know how much refridgerant oil to add to the system.Also I'd like to put a safety switch on the receiver and need a switch part# the thread is 1/8 pipe thread. I'm assuming that the best thing to do is remove the screen in the small hose near the evaporator. Anything else I should know?
Thanks, Guy

One can of AC oil mixed with the freon of your choice will be enough. You didn't mention which freon your system uses. If its R-12, the freon/oil mix is inexplicably still for sale over the counter in CA & other restrictive states. Same goes for R-134a but NEVER mix the two oils; they gel when mixed. If running R-134a, its recommended to change the dryer and the expansion valve to one made specifically for R-134a. These expansion valves normally don't have the filter-screen installed, to get higher flow rates. Can't help with the switch p/n- go to an AC shop & ask what they recommend
