Operating the machine outside of the above
limitations, or outdoors, is potentially damaging to
the machine; also it is misuse of the machine,
which may void the warranty.

Scotsman Ice Systems are designed and
manufactured with the highest regard for safety
and performance. They meet or exceed the
standards of UL and NSF.

Scotsman assumes no liability or responsibility of
any kind for products manufactured by Scotsman

Specifications and design are subject to change
without notice.

Service Limitations

Do not install in a location where the top of the

machine is within 6" of a fixed ceiling. Do not install

air cooled models in a location where there is less

than 6" clearance to the left and right of the

cabinet.

Water Limitations

An ice machine is a food manufacturing plant; it
takes 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. This section is not intended as a
complete resource for water questions, but it does
offer these general recommendations:

1. Filter the water used to produce ice. That is the
water going to the “potable” water connection.
Water filters vary greatly in ability and function.
Install one that filters out suspended solids to a
dimension of 5 microns or smaller. The finer the
filter the better, but finer filters will clog sooner than
course ones. It may be necessary to add a course
filter ahead of the fine filter to prolong filter life.

2. Check with a water treatment specialist for a
water test, and recommendations regarding filters
and treatment.

FOR THE INSTALLER

Location

After uncrating and inspection, the unit is ready for
installation. It is important that the machine be
installed in a location where it has enough space
above and behind it for service. Air cooled models
require a minimum of 6 inches to the left and right
of the machine for air circulation.

Machine Stand Installation

Tip the stand on its back and install the legs, return
the stand to the upright position. Adjust leg levelers
so that the stand does not “rock”.

Counter Top or Machine Stand Installation

The base of the icemaker-dispenser must be
sealed to the object it rests upon. Food grade
silastic sealant such as Scotsman part number
19-0529-01 is recommended.

Place a bead of the sealant on the machine stand
or counter top to match the outside edge of the
cabinet base and sink.

The icemaker-dispenser is heavy: use of a
mechanical hoist is recommended to lift it to the
height required to install it.

The DMS machine stand has holes in the top that
match up with threaded holes in the
icemaker-dispenser. Place the cabinet onto the
machine stand, so that the unit is lined up with the
holes. Secure the ice maker-dispenser to the
machine stand with bolts and washers.

In both counter top and machine stand
installations, wipe off and neatly smooth any
excess sealant. Level the machine stand and
cabinet.

Unpack and install the sink brackets. Fit the sink
assembly onto the two sink brackets, and press
onto the bead of sealant. Wipe off and neatly
smooth any excess sealant from under the sink
edge.

COUNTER

OR STAND

Unpack and install the ice and water spouts.

Ice Spout: Slide up and over ice outlet. No

fastener is required to hold it in place.

Water Spout: Slide over stainless steel water
discharge tube, locate and match up with notches
in the base. Rotate clockwise to move spout into
installed position.
