GENERAL INFORMATION AND INSTALLATION

A. INTRODUCTION

This manual provides the specifications and the
step-by-step procedures for the installation, start­up and operation, maintenance and cleaning for
the SCOTSMAN DXN 107 and DXN 207 counter
cubelet ice dispensers.
Their ice making systems are thoroughly tested
providing the utmost in flexibility to fit the needs
of a particular user.

NOTE. To retain the safety and performance
built into this icemaker, it is important that
installation and maintenance be conducted
in the manner outlined in this manual.

B. UNPACKING AND INSPECTION

1. Call your authorized SCOTSMAN Distributor
or Dealer for proper installation.

2. Visually inspect the exterior of the packing
and skid. Any severe damage noted should be
reported to the delivering carrier and a concealed
damage claim form filled in subjet to inspection of
the contents with the carrier’s representative
present.

3. a) Cut and remove the plastic strip securing
the carton box to the skid.

b) Cut open the top of the carton and remove

the polystyre protection sheet.

c) Pull out the polystyre posts from the

corners and then remove the carton.

4. Remove the top and sides panels of the unit
and inspect for any concealed damage. Notify
carrier of your claim for the concealed damage
as stated in step 2 above.

5. Remove all internal support packing and
masking tape.

6. Check that refrigerant lines do not rub against
or touch other lines or surfaces, and that the fan
blades move freely.

7. Check that the compressor fits snugly onto
all its mounting pads.

8. Use clean damp cloth to wipe the surfaces
outside of the cabinet.

9. See data plate on the rear side of the unit
and check that local main voltage corresponds
with the voltage specified on it.

CAUTION. Incorrect voltage supplied to
the icemaker will void your parts
replacement program.

10. Remove the manufacturer’s registration card
from the inside of the User Manual and fill-in all
parts including: Model and Serial Number taken
from the data plate.
Forward the completed self-addressed
registration card to SCOTSMAN factory.

C. LOCATION AND LEVELLING

WARNING. This Ice Dispenser is designed
for indoor installation only. Extended
periods of operation at temperature
exceeding the following limitations will
constitute misuse under the terms of the
SCOTSMAN Manufacturer’s Limited
Warranty resulting in LOSS of warranty
coverage.

1. Position the unit in the selected permanent
location.
Criteria for selection of location include:

Min Max
Air Temperature 10°C38°C
Water Temperature 10°C35°C
Water pressure 1 bar 5 bar
Voltage -10% +10%
(Compared to the nameplate)

Service access: adequate space must be left for
all service connections through the rear of the ice
maker.

This machine is air cooled and sucks air through
the right side panel and blows air out the rear and
left side panels. Do not install the machine where
the right side air flow might be blocked.

It is important that the machine be installed in a
location where it has enough space around it to
be accessible for service, and minimum of 15 cm
be allowed at all sides for air circulation. Try to
avoid hot, dirty and crowded locations.

NOTE. It is imperative to do not place on top
of the machine any sort of goods.

D. ELECTRICAL CONNECTIONS

See data plate for current requirements to
determine wire size to be used for electrical
connections. All SCOTSMAN icemakers require
a solid earth wire.
All SCOTSMAN ice machines are supplied from
the factory completely pre-wired and require
only electrical power connections to the wire
cord provided at the rear of the unit.
Make sure that the ice machine is connected to
its own circuit and individually fused (see data
plate for fuse size).
The maximum allowable voltage variation should
not exceed -10% and +10% of the data plate
