INTRODUCTION The manifacturer would like to thank you for having chosen its products and we are sure that you will be more than satisfied with their performance. To help maintain efficiency and performance in time, we have prepared this manual that describes the correct use and maintenance of the Blast Chiller Freezer.
Page 4: Regular Maintenance
TECHNICAL ASSISTANCE Thanks to the network of concessionaires and authorised service centres, the manufacturer guarantees its customers an after-sales service. REGULAR MAINTENANCE WARNINGS Regular maintenance work can be carried out by non-specialised personnel who, however, must always adhere to the instructions given in this manual. Before cleaning or servicing the chiller lock-off the power supply.
Page 5: Extraordinary Maintenance
When the Chiller is out of service for a long period of time take the following measures: Remove the plug from the power socket; Remove all food and clean the inside of the Chiller and all accessories; Buff all the stainless steel surfaces with a cloth moistened with vaseline oil to give a protective coating;...

WASTE DISPOSAL AND SCRAPPING Storing waste: It is possible to temporarily store special waste products that are to be scrapped. However, the user must observe and adhere to the local governing laws regarding waste management. Macro – dismantling the Chiller: Each country has its own waste management laws, therefore the user must observe and adhere to the local governing laws where the Chiller is to be scrapped.
Page 7: Installation
The Chiller has no dangerous corners, sharp and cutting surfaces or protruding parts. All safety guards on moving parts or electrics are screwed to the cabinet. These guards avoid any form of accidental contact with parts that present a risk to the user. Always respect safety standards: Do not touch the Chiller with wet hands or feet;...

The socket is earthed and frequency and tension correspond to the information given on the metal plate. If in doubt about earthing, call in a qualified electrician to check wiring. A suitable thermomagnetic switch must be provided between the power cable and electricity line with at least a 3 mm break contact.
Page 9: Blast Chilling
CYCLES BLAST CHILLING The blast chilling cycle rapidly lowers the temperature of the food to a minimum of +3 °C. Blast chilling is for food that will be consumed within a few days. BLAST FREEZING Blast freezing is for storing food for longer periods of time. When blast freezing the water content in the food is micro crystallized so when defrosting the food is not altered in any way maintaining both its appearance and nutritional value.
