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.MOA outdoor units are listed as R-454B on Senville's pages and NEEP; NEEP lists the MOB units as R-410A, and an owner of an earlier SENA-28HF-MOA reports R-410A. Confirm the refrigerant on the label. Senville's FAQ says owner installs are not supported; the warranty certificate requires a licensed professional, and labor is never covered.
