Hello All,
reading these things about what is where from 4 different people is
confusing.

This is the how the AC is hooked up.
Compressor to evaporator is the high pressure.
Low pressure goes first to the condensor in front of the Van and then
back to the dryer, and then to the evaporater finishing the loop.

High pressure valve is behind the rear panel, the low pressure valve is
on the compressor.

Good Morning,

Fred
