Topics:

• Sub-Zero installed in a garage during the winter
• Sub-Zero installed outdoors where temperatures get very cold
• Can heat be added to a Sub-Zero to allow running in cold temperatures?
• What will happen if a refrigeration product is installed in a cold-weather setting?

Answer:

Sub-Zero products are not designed to operate in a garage or outdoors where it will encounter below-freezing temperatures.

• Except for outdoor models, Sub-Zero products are designed to run in a 60°F to 90°F (15°C to 32°C) environment.
  • Refrigeration units are not designed to heat. They remove heat from the compartment and cannot add heat to it.
  • When a unit reaches a temperature below the lowest setpoint, it will not work properly.
  • This applies to Wine Storage units as well.
• For best operation, the unit should be in a normal ambient temperature location.
• A Sub-Zero in a vacated home that is not heated should be winterized. See Winterizing Sub-Zero Products.
• For information about outdoor models, which tolerate a wider temperature range, refer to Sub-Zero Outdoor Unit Temperature Range for Installation.
