Anyone have a service manual for this new unit. This is one of the 2 evap systems that we are going to be seeing. These new units have a valve that puts freon from one evap to the other. We have saw this before,ok. But with check valves installed in the system you cant blow restictions out. So your only option is vacum it.Ok ,but with a check valve in the system how does the pressure equal out.And do you open the valve to evap the units like a Samsung. Any information would be great. Thank you.
