When installing a new system,
check to be sure that you have
everything you need before
beginning:

· Correct Bin

· Correct Ice Machine

· Correct Bin Top (if required)

· All kits, legs, and information

required for the specific job.

Note: Allow 6" behind and 6"

above the unit for air

circulation, utility

connections, and service.

FOR THE IN STALLER: En vi ron men tal Lim i ta tions

Installation Limitations:

This ice system is designed to be installed indoors,
in a controlled environment:

Min Max
Air Temperature 500F 1000F
Water Temperature 400F 1000F
Water Pressure 20 PSI 80 PSI
Voltage 198 VAC 253 VAC
(Compared to the nameplate)

Operating the machine outside of the limitations is
misuse and can void the warranty.

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 is not intended as a complete
resource for water related questions, but it does
offer these general recommendations:

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

2. In most cases, the water used to make ice
should be filtered or treated, depending upon the
water. There is no one type of water filter that will
be effective in all situations. That is why a water
test is important.

RO Water Limitation: Water conductivity must be
no less than 35 microSiemens/cm.

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

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 part 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 design are subject to change
without notice.

Lo ca tion:

After uncrating and inspection the unit is ready for
installation. Install the machine in a location where
it has enough space around it to be accessible for
service, and reserve a minimum of 6" at the back
for air circulation on air cooled models.

Avoid hot, dirty and crowded locations. Be sure
that the location for the machine is within the
limitations described on page 3.

Stor age Bin:

Tip the storage bin on its back, using parts of the
carton to protect the exterior finish. Install the legs
into the threaded holes in the bottom of the bin.
Turn the leg levelers all the way in preparation for
leveling later. Return the bin to the upright
position, remove paper covering the bin gasket.

Note: Do not push bin into position, instead lift it
there. Pushing a bin, especially one with ice in it,
can cause damage to the legs and the leg mounts.

Install the appropriate bin top on the bin, according
to the instructions for the bin top.

Ice Ma chine:

The machine is heavy, so the use of a mechanical
lift is recommended for lifting the machine high
enough to install on top of the bin. After the unit is
placed on the bin, line it up so it is even with the
back side. Secure the machine to the bin with the
hardware provided with the machine.

Remove the front panel and remove any shipping
blocks.

Wa ter In let

Air Cooled Models: Connect to a water supply

that is cold and potable. Use
tubing, and connect to the single
the back of the cabinet. This connection supplies
water to both ice making systems. Install a hand
valve near the machine to control the water supply.

Water Treatment: In most areas, a water filter of
some type will be useful. In areas where the water
is highly concentrated with minerals the water
should be tested by a water treatment specialist,
and the recommendations of the specialist
regarding filtration and/or treatment should be
followed.

Drains

Air Cooled Models: Connect a drain tube to the

one ¾" FPT gravity drain fitting at the back of the
cabinet (used or both ice making systems). A ¼
inch per foot fall is the minimum pitch for the drain
tubing. There MUST be a vent at the highest point
of the drain line, and the ideal drain receptacle is a
trapped and vented floor drain.

Use only ¾" rigid tubing.
Storage Bin: Connect a separate gravity type

drain tube, similar to the air cooled drain. Insulation
of this drain line is recommended.
