FOR THE INSTALLER: Specifications

This ice maker-dispenser is designed to be
mounted on a machine stand, or a countertop.
Before beginning the installation, check that all the
materials and kits required are available at the
installation location.
Scotsman Ice Systems are designed and
manufactured with the highest regard for safety
and performance.  They meet or exceed the
standards of U.L., N.S.F., and C.S.A.
Scotsman assumes no liability or responsibility of
any kind for products manufactured by Scotsman

that have been altered in any way, including the
use of any parts and/or other components not
specifically approved by Scotsman.
Scotsman reserves the right to make design
changes and/or improvements at any time.
Specifications and designs are subject to change
without notice.
Water Limitations:
An ice machine is a food manufacturing plant; it
takes in a raw material, water, and turns it into a
food product, ice. The purity of the water is very

important in obtaining pure ice
and in maximizing product life. 
General recommendations
are:
1. Filter the water used to
produce ice. 
2. Check with a water
treatment specialist for a
water test, and any
recommendations regarding
filters and treatment.
