  • Is it possible to Dual Install two 648PRO units?
  • Install a 648PRO with another Sub-Zero Unit.
  • Is a dual installation kit needed to install a 648PRO next to another Sub-Zero?


A dual installation package is not available for 648PRO or 648PROG models.
  • A 2" filler is recommended for proper clearance as there are hinges on both sides.
  • Two 648PRO units placed next to each other can not use a dual installation kit.
  • If placing a 648PRO closer than 2" to a different unit, use the dual installation heater on the other unit, using the heater appropriate for that model.
