Very good make; but RUUD might have ruined it. So much bad information;not even enough for an urban legend.
People: RAKA 048JAZ IS NOT "370 VOLTS," NOR "600 VOLTS!. tHEY ARE 220/230 1 Phase usually -can go 3Ph. They were made from 2001?; and most sold between 2003 and 2006.
R-22 was turn-of-the-21stcentury "Ozone friendly" coolant cf. Freon, but at the end of the decade ONLY a more "Ozone friendly" "401" is allowed.

But Rheem's web sites only seem to go back to post-2005 stuff; so no manuals, .pdf downloads, etc. [I wanted to get how much power a 4-5 ton unit uses like 2006 is 10-17kw; NOT its minimum "amperacity of 32A."]
