Worked on replacing a compressor on a package Lennox Heat Pump, and put a new liquid filter drier also. Put the unit back in service and everyting works okay, but then found out later we installed the liquid drier backward. Opps! We goofed up. We intend to go back this weekend when the building is unoccupied and correct it. My question is - what is the immediate consequence(s) having a drier installed backward? Thanks for your advice.
