1. Safety instructions
Attention!
Read the information given in the user manual carefully (see Chapter 2, Page 2-1).
1.1 Hygiene
Note:
Prior to commissioning do the daily cleaning (see Chapter "Cleaning").
Attention!
• Please follow the generally valid hygiene HACCP regulations!
(HACCP= Hazard Analysis and Critical Control Point)
• Do not use raw milk. Use only pasteurised or UHT milk. Homogenized milk must always be used.
• Milk that has already been heated up or for which the expiry date has lapsed may not be used.
• When using packaged milk, it is recommended for hygienic reasons to use the milk directly from
the original packaging.
• The milk in the refrigerator must have a temperature of approx. 3 °C to 5 °C. If this rule is not
followed, it is not possible to dispense an optimal product.
• Only refill with milk which has not exceeded 5 °C. Never put warm milk in the refrigerator. It takes
too long for a temperature of 3 °C to 5 °C to be reached. The refrigerator will also ice up.
(Frequent defrosting required).
• For daily and weekly cleaning, proceed as described in chapter "Cleaning".
• Never spray the machine with water or other liquids.
• For cleaning, never immerse the machine in water or any other liquid.
Danger!
During cleaning and usage of cleaning tools or products, there is a risk of injury.
