Air conditioner oil

[Gary L]

Can anyone tell me how much oil to put in the AC system of a CH613 when it's been drained and flushed?

Thank you,

sanden compressor? did you drain the compressor? if comp. was drained refill with recommended amount for compressor I'm going from memory so double check me 10.oz. seams right to refill the comp.

Would it make a difference it has a unit in the bunk? that might add more oil

I found a chart that said to put 5 oz in compressor but you need some in the dryer , condenser and evaporator to don't you?

Thank You

hate to say when I don't know for sure, but 5oz. seems low to me .I just went to( sanden usa) and looked at a sd7 which is a common truck compressor and 10oz. is standard comp. fill. However it went on to say that orifice tube systems 240cc. thermal expandsan tube system 135cc.

so I would suggest going to their web site and using their info, they also had the formula to figure extra oil needs based on extra evaporators an longer hose runs and how to calculate this based on refrigerant quantity.
