Watch out forAmazon Leto listings don't state refrigerant; current R-454B pairings are SENL-xxCD-OL + SENL-xxCD-ILL, older R-410A ones end /OY + /IY. Senville's FAQ says no to owner installs, and the warranty requires a licensed HVAC contractor.Install 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.
