ctenophore January 6, 2010 Share January 6, 2010 Just wondering if anyone in WAMAS is a professional HVAC tech. I want to install one of these in my greenhouse to make it more pleasant in the winter. I can do (or help with) pretty much everything except weld the copper and charge the system with refrigerant. PM me if you are interested. Thanks!

Coral Hind January 6, 2010 Share January 6, 2010 You can also run the copper lines as there are no soldering of pipes needed. You run 3/8" and 5/8" coiled copper tubing. Connections are flared compression fittings. Link to comment Share on other sites More sharing options...
zygote2k January 6, 2010 Share January 6, 2010 After you do your copper connections, be sure to run a vaccuum on the lines to detect any leaks, then fill it with refridgerant. I would offer my services, but I have been out of the HVAC world for more than 15 years. Link to comment Share on other sites More sharing options...

Justin most units have a precharge but you would have to run a vacumm on the lines as zygote2k said. as for the copper pipe, if you sweated a water pipe you can sweat an ac tube just make sure you use brazing rod and MAP gas.
