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 ° C.
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:
