ice making capacity

ELECTRONIC FLAKER MODEL AF 80

NOTE.Withtheunitin“built-in”conditions,the ice production isgraduallyreduced in respect tothe

levels shown in the graph, up to a maximum of 10% at room temperatures higher than 32

The daily ice-making capacity is directly related to the condenser air inlet temperature, water

temperature and age of the machine.

To keep your SCOTSMAN FLAKER at peak performance levels, periodic maintenance checks

must be carried out as indicated on page 36 of this manual.

Important operating requirements:

- Air temperature 10°C (50°F) 40°C (100°F)

- Water temperature 5°C (40°F) 40°C (100°F)
