YES. That is the directions i used. I got from you the evaporator a dryer, 3cans of freeze 12, frigi quiet, then a side can tap when I discovered the cans were different from 134. Most of the frigiquiet leaked out when i turned it sideways to install the compressor so i added 2oz of freeze 12 oil. I wrapped the expansion valve with something someome called monkey do to reduce condensation on the expansion valve. Was there something you think I might have done wrong or out of sequence that may have caused my problem other than useing the old low pressure switch and old temp fan switch on the new dryer. RAY M
