Scotsman AF300 Parts Manual

This is the parts list for the AF300. When looking
up part numbers, always check the complete
model and serial numbers to be certain of ordering
the correct parts.

Plastic tubing is sold by the foot, order 1 unit, and
1 foot will be shipped. Order enough to cover the
length required. Lengths of tubing are listed under
the description column.

Note: The reservoir was changed in July of 1994
(date code -01Z). The two different reservoirs are
NOT interchangeable. Check the body color of the
reservoir before ordering a part.
