Installation

Unpack and inspect contents. Position on level floor.

  1. Choose location: Place on stable, level surface away from heat sources and direct sunlight.
  2. Ventilation: Ensure minimum clearance (5 cm sides, 10 cm back, 30 cm top) for air circulation.
  3. Level appliance: Adjust front feet using a wrench to ensure door closes properly.
  4. Electrical connection: Plug into grounded 220-240V/50Hz outlet. Do not use extension cords.
  5. Door reversal (if needed): Follow instructions in separate door reversal guide.

WARNING! Freezer is heavy; use two people for moving. Ensure proper ventilation to prevent overheating.

First-Time Setup

After installation, allow freezer to stabilize before use.

  1. Initial cooling: Plug in and switch on. Set to recommended temperature (-18°C).
  2. SuperCool mode: Activate SuperCool for 24 hours before loading food to achieve optimal temperature.
  3. Temperature setting: Use control panel to set desired freezer temperature.
  4. Alarm test: Check door alarm by leaving door open for 2 minutes (alarm should sound).
  5. Load food: Once temperature is stable, arrange food items evenly.

CAUTION! Do not load large quantities of unfrozen food at once. Allow freezer to reach set temperature first.

Specifications

Settings: Temperature setting (press +/- to adjust), SuperCool (activates for 24 hours then auto-off), Alarm (can be muted temporarily), Child lock (press and hold for 3 seconds to enable/disable).

Temperature Management

Optimal freezer temperature is -18°C for food preservation.

  1. Adjust temperature: Use +/- buttons. Allow several hours for stabilization after change.
  2. SuperCool: Use before adding large amounts of unfrozen food. Activates for 24 hours maximum.
  3. Monitoring: Display shows actual internal temperature. Fluctuations during door opening are normal.
  4. Energy saving: For long absences, set to -18°C; do not unplug. Use vacation mode if available.

Tip: Keep door openings brief and infrequent to maintain stable temperature.

Storage Organization

Organize food for optimal freezing and easy access.

  1. Shelves: Adjust height to accommodate different package sizes.
  2. Door compartments: Store smaller items, frozen vegetables, ice packs.
  3. Labeling: Label packages with contents and date for first-in-first-out use.
  4. Air circulation: Do not overpack; allow air to circulate around items.
  5. Hot food: Cool to room temperature before freezing to reduce energy use.

WARNING! Do not block air vents inside freezer. Ensure packages are sealed to prevent freezer burn.

NoFrost Technology

Automatic defrosting system eliminates ice buildup.

How it works: A fan circulates cold air evenly. Evaporator coils periodically heat to melt frost; water drains to evaporation tray.

Benefits: No manual defrosting needed, consistent temperature, better energy efficiency, more storage space (no ice buildup).

Note: Slight humming during defrost cycle is normal. Ensure drainage hole at back is not blocked.

Care & Cleaning

Unplug before cleaning. Use mild detergent and soft cloth.

  1. Interior: Remove all food. Wipe shelves and walls with solution of warm water and mild detergent. Rinse with damp cloth and dry.
  2. Exterior: Clean door and control panel with soft damp cloth. Do not use abrasive cleaners.
  3. Door seals: Wipe gaskets regularly to ensure proper seal.
  4. Condenser coils: Vacuum rear coils annually to maintain efficiency (only if accessible).

CAUTION! Never use sharp objects to remove ice (not needed with NoFrost). Do not use chemical or abrasive cleaners.
