ice making capacity

NOTE.

With the unit in “built-in” conditions, the ice production is gradually reduced in respect to the

levels shown in the graf, 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 CUBER at peak performance levels, periodic maintenance checks

must be carried out as indicated on page 38 of this manual.
