Questions and answers
How to adjust the ice thickness,since ice is to thick
To adjust the ice thickness on the Scotsman NW507:
1. Locate the ice thickness sensor near the evaporator.
2. Adjust the screw that sets the distance between the sensor reeds and the egg-crate evaporator.
3. Be careful not to set it for single ice cubes, as this may cause machine malfunction.
4. After adjustment, observe the second and third cube harvests to verify the correct size and shape of the ice.
The first freezing time should range between 15 and 20 minutes depending on the ambient temperature.
