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.
11. If necessary, on model EC 56, replace the
fourstandardlegswiththetalleronessuppliedin
the machine and adjust them to level the unit.
C. LOCATION AND LEVELLING
WARNING.ThisIce Cuber is designed for
indoorinstallationonly.Extendedperiods
of operation at temperatures exceeding
the following limitations will constitute
misuseunderthetermsoftheSCOTSMAN
Manufacturer’sLimitedWarrantyresulting
in LOSS of warranty coverage.
1. Position the unit in the selected permanent
location.
Criteria for selection of location include:
a)Minimumroomtemperature10°C(50°F)
and maximum room temperature 40°C (100°F).
b) Water inlet temperatures: minimum 5°C
(40°F) and maximum 35°C (90°F).
c) Well ventilated location for air cooled
models.
d)Serviceaccess:adequatespacemustbe
leftforallserviceconnectionsthroughtherearof
the ice maker. A minimum clearance of 15 cm
(6")mustbeleftatthesidesoftheunitforrouting
cooling air drawn into and exhausted out of the
compartment to maintain proper condensing
operation of air cooled models.
2. Level the unit in both the left to right and
front to rear directions.
D. ELECTRICAL CONNECTIONS
See data plate for current requirements to
determine wire size to be used for electrical
connections.AllSCOTSMAN icemakersrequire
a solid earth wire.
A. INTRODUCTION
This manual provides the specifications and the
step-by-stepproceduresfortheinstallation,start-
up and operation, maintenance and cleaning for
the SCOTSMAN EC series icemakers.
These Cubers are quality designed, engineered
and manufactured.
Their ice making systems are thoroughly tested
providing the utmost in flexibility to fit the needs
of a particular user.
These icemakers have been engineered to our
own rigid safety and performance standards.
NOTE .Toretainthesafetyandperformance
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. CallyourauthorizedSCOTSMANDistributor
or Dealer for proper installation.
2. Visually inspect the exterior of the packing
and skid. Any severe damage noted should be
reportedtothedeliveringcarrierandaconcealed
damageclaimformfilledinsubjettoinspectionof
the contents with the carrier’s representative
present.
3. a)Cutandremovetheplasticstripsecuring
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 front panel of the unit and
inspectforanyconcealeddamage.Notifycarrier
ofyourclaimfortheconcealeddamageassteted
in step 2 above.
5. Check that refrigerant lines do not rub
againstortouchother lines or surfaces, and that
the fan blade moves freely.
6. Check that the compressor fits snugly onto
all its mounting pads.
7. Remove all internal support packing and
masking tape.
8. Use clean damp cloth to wipe the surfaces
inside the storage bin and the 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.
GENERAL INFORMATION AND INSTALLATION

Page 10
Page 10
All SCOTSMAN ice machines are supplied from
thefactorycompletelypre-wiredandrequireonly
electrical power connections to the wire cord
provided at 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).
Themaximumallowablevoltagevariationshould
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
Whenchoosingthewatersupplyfortheicecuber
consideration should be given to:
a) Length of run
b) Water clarity and purity
c) Adequate water supply pressure
Sincewateristhemostimportantsingleingredient
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 cloudy coloured ice cubes, plus scale
build-up on parts of the water system.
WATER SUPPLY
Air Cooled Versions
Connect the 3/4" male fitting of the solenoid
waterinletvalve,usingtheflexibletubesupplied,
tothecoldwatersupplylinewithregularplumbing
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 use an appropriate
water filter or conditioner.
Water Cooled Versions
Water Cooled version has water inlet solenoid
valve for the condenser.
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.
WATER DRAIN - WATER COOLED MODELS
Connect the 3/4" male fitting of the condenser
water drain, utilizing a second flexible hose, to
the open trapped and vented drain.
NOTE. Thewatersupplyandthewaterdrain
must be installed to conform with the local
code. In some case a licensed plumber and/
or a plumbing permit is required.
The EC series Ice Cubers can pump out water
up to 1.5 m rise
or to 30 m on horizontal length.
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? (IMPORTANT)
4. Have all the electrical and plumbing
connectionsbeenmade,and isthe watersupply
shut-off valve open?
