Watch out forInstall type 'quick-connect' assumes MRCOOL's optional No-Vac line set; the system also ships for flare or braze connections with a vacuum. Some Amazon listings carry older CENTRAL-xx-HP-230A00 model codes; match the 230B00-O suffix. The install manual still calls for a licensed installer and licensed field piping; the warranty is what exempts a Quick Connect install.The LIVO+ (LIVS..., R-410A, 16 SEER) and Livo Gen 3 / Gen 4 (4LIV, R-410A) are different units; confirm both model numbers end R32AO and R32AH. The 18K Amazon listing titled "Gree R32 LIVO+" reports the R-410A LIVS18HP230V1B; we don't link it. Gree's warranty applies only to installs by a state certified or licensed HVAC contractor, and claims are contractor-only.
