NoFrost Technology

Peak NoFrost automatically removes moisture, preventing ice buildup.

How it works: A fan circulates cold air; moisture condenses on a hidden evaporator.
Defrost cycle: Automatically activates; melted water evaporates.
Benefits: No need for manual defrosting; consistent temperature.
Maintenance: Keep air vents clear for optimal airflow.

WARNING! Do not block air vents with food packages.

Energy Saving Tips

Place in a cool location away from heat sources. Ensure door seals are clean and tight. Allow hot food to cool before freezing. Do not open door frequently. Keep freezer at least ¾ full for efficiency.

Care & Cleaning

Unplug before cleaning. Use mild detergent and warm water; rinse and dry.

Interior: Clean shelves and bins with soft cloth.
Exterior: Wipe with damp cloth; avoid abrasive cleaners.
Door seals: Clean gently to maintain seal integrity.
Condenser: Vacuum dust from rear grille every 6 months.

CAUTION! Never use sharp objects to remove ice (not required with NoFrost). Do not use steam cleaners.
