Optimal cooling modes: how keep food fresh
Temperature conditions in CoolFreeze CDF-18 depend on the type of product and operating conditions. Here are recommendations for different scenarios:
- 🥩 Meat and fish: −18°C (freezing) or 0…+2°C (short-term storage up to 2 days).
- 🥛 Dairy products: +2...+4°C (do not allow freezing!).
- 🍎 Fruits and vegetables: +4...+8°C (in a separate container to avoid hypothermia).
- 💊 Medicines: +2...+8°C (check the instructions for the drug!).
Important: at ambient temperatures above +30°C, the refrigerator operates at its maximum capacity. In such conditions:
- Increase pre-cooling time (up to 3-4 hours).
- Use thermal insulating blanket for the case.
- Reduce the frequency of opening the door.
To control the temperature inside the chamber, use external thermometer (it is not included in the kit). The built-in sensor shows the average value, which may differ from the real one by 2-3°C.
What to do if the refrigerator does not cool to −18°C?
The reason may be high ambient temperature (above +35°C) or insufficient power. Try:
1. Switch to 220 V (if possible).
2. Reduce the load of products.
3. (must be at least 12.5 V).
Care and cleaning: how to extend service life
Regular maintenance Waeco CoolFreeze CDF-18 prevents the appearance of mold, unpleasant odors and breakdowns Basic procedures:
- Cleaning the interior. cameras:
- 🧼 Use a warm solution of baking soda (1 tablespoon per 1 liter of water).
- 🚫 Avoid abrasive products and hard sponges - they damage the plastic.
- Caring for the seal:
- 🧴 Wipe the rubber gasket with silicone grease once every 3 months.
- 🔍 Check the integrity: cracks or deformations lead to cold leakage.
- 🧹 Remove dust from the ventilation grilles with a soft brush.
- 🌬️ Do not close the grilles - this causes the compressor to overheat.
- Turn off the refrigerator and leave the door open.
- Place a container with warm water inside (not boiling water!).
- Wipe the walls with a dry cloth after the ice melts.
Defrosting is required only when ice forms more than 5 mm thick. To speed up the process:
