CUBER MODEL EC 46

NOTE

. With the unit in "built-in" conditions, the ice production is gradually reduced in respect to the
levels shown in the graf, up to a maximum of 10% at room temperatures higher than 32°C.
The daily ice-making capacity is directly related to the condenser air inlet temperature, water
temperature conditions of the condenser air filter and age of the machine.

To keep your SCOTSMAN CUBER at peak performance levels, periodic maintenance checks must
be carried out as indicated on Maintenance and Cleaning section of this manual.

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.

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 fill­in all parts including: Model and Serial Number
taken from the data plate.
Forward the completed self-addressed
registration card to Frimont factory.

11. If necessary, on model EC 56, replace the
four standard legs with the taller ones supplied in
the machine and adjust them to level the unit.

C. LOCATION AND LEVELLING

WARNING. This Ice Cuber is designed for
indoor installation only. Extended periods
of operation at temperatures 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:

a) Minimum room temperature 10°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) Service access: adequate space must
be left for all service connections through the rear
of the ice maker. A minimum clearance of 15 cm
(6") must be left at the sides of the unit for routing
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. All SCOTSMAN icemakers require
a solid earth wire.

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 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

. 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 front panel of the unit and
inspect for any concealed damage. Notify carrier
of your claim for the concealed damage as steted
in step 2 above.

5. Check that refrigerant lines do not rub
against or touch other 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.
