solder. Be careful to protect the expansion valve with a cold wet rag or a commerical heat protction
product.
14.
Install the new ¼" dryer in the liquid line.
15.
Pressure test the system for leaks with dry nitrogen.
IMPORTANT: Do not exceed the nameplate pressure ratings!
16.
Evacuate the system to at least 500 microns.
17.
Re-charge the system using a refrigerant scale or a Dial-a-Charge to the exact nameplate
specifications.
18.
Re-insulate the refrigeration lines.
