Sub-Zero Dual Installation Water Supply Line


  • Water supply requirements for two Sub-Zero units in dual installation application
  • Can units that are installed next to each other use the same water supply line?
  • Is it necessary to have a separate water supply line for dual installed Sub-Zero units?


When installing two Sub-Zero units next to each other, refer to the installation guide for each product for water supply requirements.

  • Adequate water pressure is required for proper ice production and water dispenser function.
  • Both units can be supplied by the same water line as long as the pressure is adequate for both units.
  • A pressure booster may be necessary for proper pressures.
