quantity of food kept inside the fridge.
• Do not pass to another adjustment before completing an adjustment.
• Your fridge should be operated up to 24 hours according to the ambient temperature without
interruption after being plugged in to be completely cooled. Do not open doors of your fridge
frequently and do not place much food inside it in this period.
