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°
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 CUBER at peak performance levels, periodic maintenance checks must
be carried out as indicated on page 40 of this manual.

Frequently Answers and Questions
What are the important operating requirements for Scotsman AC series icemakers?
The manual states that the minimum ambient temperature is 10°C (50°F) and the maximum is 40°C (100°F). The minimum water temperature is 5°C (40°F) and the maximum is 35°C (90°F). The water pressure should be between 1 bar (14 psi) and 5 bars (70 psi). The electrical voltage variation should not exceed -10% and +10% of the data plate rating.
What is the ice-making capacity of the AC series icemakers?
The ice-making capacity is specified on pages 3-15 of the viewed document, and it varies for each model depending on the ambient temperature, water temperature, and whether the model is air-cooled or water-cooled.
What kind of maintenance checks should be carried out periodically?
The manual suggests periodic maintenance checks as indicated on page 40 of this manual. These checks are essential for maintaining peak performance levels of the Scotsman Cubers.
What is the recommended drain tube size?
The recommended drain tube is a plastic or flexible tube with 18 mm (3/4") I.D. which runs to an open trapped and vented drain.
