The panels from model 550 will fit model BI-36U or BI-36UID with the purchase of a retrofit kit, grille, and handle.

  • Retrofit kit, part number 7005229.
  • Louvered grille, part number 7014850.
    • The louvered grille insert needs to be purchased as a decorative framed grille. Panels from an earlier Sub-Zero series cannot be installed on a Classic (formerly Built-In) product. The custom panel dimensions are different and it will not fit.
    • If used, order a new reduced height or extended grille. See Classic Series Grille Height Options.
    • If unit has a grille panel, refer to Grille Panel.
  • Framed handle set, part number 7014889 (or an extended handle set, part number 7003464).
    • Order a new handle because the handle is longer, so the drill holes will not line up.
  • Side panels cannot be reused.
