I'm new at installing Energy Saver Hi-Velocity Systems. Why does the manufacturer insist on putting the access ports & sightglass at the evaporator end of the system. I'm use to seeing these components at the condenser outside. It seems like it would be easier when it comes to evacuating, troubleshooting, and or charging to have these components outside instead of up in the attic. Has anyone out there installed these outside bt the condenser without any consequences?
