Before you buy

  • The Klimaire Entrada (KIWE/KOIE, -31X, R-32, 17 SEER2) is a flare-and-vacuum unit; the DIY title reads "23 SEER2 Quick Connect".
  • The 4th Gen DIY used the same KIWQ/KOIQ prefixes at 19.0 SEER2; confirm the -45T suffix and R-454B.
  • The warranty page allows DIY installs, but the warranty PDF says licensed contractors only and excludes line sets. Get the DIY terms in writing and register within 45 days.
  • The manual says the EZ-Fast Connect fittings are one-time tightening.
