Sub-Zero vacation setting recommendations are as follows:

  • Use vacation settings as a preventative measure.
  • Exceptions to recommendations are done at the owner's discretion.

Short Vacations (1 week or less)

  • Remove all perishable items.
  • Shut off the ice maker and empty the ice bin. See also, Turn Ice Maker On or Off.
  • For models without an ice maker on/off button, remove the ice bin to turn the ice maker off.
  • Do not change the electronic control system settings.

Extended Vacations (more than 1 week)

  • Turn power off at the control panel or circuit breaker on models without control panels.
  • Empty the unit and block doors open to let fresh air in and keep interior dry.
  • Upon return, if equipped, discard and replace the water filter with a new filter before start-up.
  • Water does not need to be turned off during extended vacations but is a good preventative measure if possible.
  • If water valves leak, they could damage floors.
  • Leaving the unit on could cause issues in the home if gone for extended periods.
  • If unit stops cooling, it could ruin the inside of the unit.
  • Units are designed to be opened occasionally when running.
  • Turn off water and power for Undercounter Ice Makers. Do not leave the unit on with the water supply turned off. See also, UC-15I Undercounter Ice Maker Vacation Settings.

Unheated Homes & Cold Temperatures

  • Refer to Winterizing Sub-Zero Products for instructions.
  • Turn the water supply source off as a precaution to freezing water lines.
  • Find the water supply shut-off valve and turn it off as well.
