UC Undercounter Dual Installation Kit Instructions detail the installation process.

  • UC-24 side-by-side installations without a custom filler strip require a dual installation kit, part number 7030447.
    • The dual installation kit can be used on indoor and outdoor models.
    • The dual installation kit does not add additional width to the opening.
    • The middle trim of the dual installation kit is stainless steel.
    • Undercounter Wine Storage units, models 424 and UW-24, use the same installation kit.
    • High altitude glass door units must be installed next to each other for the installation kit to align properly. Refer to Sub-Zero High Altitude Doors for more information.
  • If a dual installation kit is not used, Sub-Zero recommends a 2" filler strip between units.
  • Dual installations of UC-24 and Undercounter Wine Storage products without a filler strip can only be accomplished using two units with opposite hinges.
  • If the units have hinges on the same side, use a filler strip to prevent binding.
  • A connector to accommodate the dual installation heater was added to UC-24 models starting with serial number 3603000.
    • Units prior to this serial number do not have a connector to connect the dual installation kit, so a connector is not required.
    • The heater attaches to the left side of the right-hand unit.
    • The UC-15I does not require a heater kit, as it is not a refrigerated compartment and does not have the moisture potential of a cooling system.

Refer to the Sub-Zero Design Guide or to Reveal, the custom specification tool, for design specifications and custom panel dimensions.
