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 TC 180 counter nugget ice
dispenser.
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 EUROPE
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°C40°C
Water Temperature 5°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 left side panel and blows air out the rear side
of the top panel. Do not install the machine where
the left side air flow might be blocked. A minimum
clearance of 15 cm is required.
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 150
mm be allowed at the left and upper side 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 and leave
the upper lowers open for proper air exhaust.
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).
Page 6
Page 6
The maximum allowable voltage variation should
not exceed -10% and +10% of the data plate
rating. Low voltage can cause faulty functioning
and may be responsible for serious damage to
the overload switch and motor windings.
NOTE. All external wiring should conform to
national, state and local standards and
regulations.
Check voltage on the line and the ice maker’s
data plate before connecting the unit.
E. WATER SUPPLY AND DRAIN
CONNECTIONS
GENERAL
When choosing the water supply for the ice flaker
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Since water is the most important single ingredient
in producting ice you cannot emphasize too
much the three items listed above.
Low water pressure, below 1 bar may cause
malfunction of the ice maker unit.
Water containing excessive minerals will tend to
produce scale build-up on the interior parts of the
water system while too soft water (with too lo
contents of mineral salts), will produce a very
hard flaker ice.
PLUMBING CONNECTIONS MUST
CONFORM TO ALL APPLICABLE CODES
CONNECT TO POTABLE WATER ONLY
The model TC 180 has the possibility to have the
water connections through the bottom base or
through the rear bottom side of the machine. In
this second case it is necessary to remove the
rear bottom small panel.
WATER SUPPLY
Connect the 3/4" GAS male of the water inlet
fitting, using the flexible tube supplied to the cold
water supply line with regular plumbing fitting
and a shut-off valve installed in an accessible
position between the water supply line and the
unit.
If water contains a high level of impurities, it is
advisable to consider the installation of an
appropriate water filter or conditioner.
WATER DRAIN
The recommended drain tube is a plastic or
flexible tube with 18 mm (3/4") I.D. which runs to
an open trapped and vented drain. When the
drain is a long run, allow 3 cm pitch per meter
(1/4" pitch per foot).
Install a vertical open vent on drain line high point
at the unit drain connection to ensure good
draining.
The ideal drain receptacle is a trapped and
vented floor drain.
NOTE. The water supply and the water drain
must be installed to conform with the local
code. In some case a licensed plumber and/
or a plumbing permit is required.
F. FINAL CHECK LIST
1. Is the unit in a room where ambient
temperatures are within a minimum of 10°C
(50°F) even in winter months?
2. Is there at least a 15 cm (6") clearance
around the unit for proper air circulation?
3. Is the unit level?
4. Have all the electrical and plumbing
connections been made, and is the water supply
shut-off valve open?
5. Has the voltage been tested and checked
against the data plate rating?
6. Has the water supply pressure been checked
to ensure a water pressure of at least 1 bar
(14 psi).
7. Check all refrigerant lines and conduit lines
to guard against vibrations and possible failure.
8. Has the owner/user been given the User
Manual and been instructed on the importance of
periodic maintenance checks?
9. Has the Manufacturer’s registration card
been filled in properly? Check for correct model
and serial number against the serial plate and
mail the registration card to the factory.
10. Has the owner been given the name and the
phone number of the authorized SCOTSMAN
Service Agency serving him?

OPERATING INSTRUCTIONS
START UP
After having correctly installed the ice maker and
completed the plumbing and electrical connections, perform the following “Start-up” procedure.
A. Open the water supply line shutoff valve and
give power by moving the main switch, on the
power supply line, to the ON position.
The GREEN LED will glow to signal that unit is
under power.
NOTE. Every time the unit is put under power,
after being kept for sometime in shut-off
conditions (electrically disconnected) the 2nd
RED LED will blink for 3 minutes (Fig.1).
FIG. 2
FIG. 1
B. Elapsed the 3 minutes - stand by period - the
unit starts operating with the activation in
sequence of the following assemblies:
GEAR MOTOR
COMPRESSOR
FAN MOTOR kept under control by the condenser
temperature sensor which has its probe within
the condenser fins
with the switching off of the 2nd RED LED
(Fig. 2).
C. Elapsed 2 or 3 minutes from the compressor
start up, observe that flaker ice begins dropping
off the ice spout to fall into the storage bin.
