INTRODUCTION

This manual provides the specifications and the
step-by-step procedures for the installation, start-
up and operation, maintenance and cleaning for
the SCOTSMAN MODULAR CUBERS.
The Electronic Modular 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 performence 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.

Storage Bin

Since the MXG series Modular Cubers do not
have their own attached ice storage bins, it is
necessary to use an auxiliary bin such as:
SB 193
SB 322
SB 393
SB 530.

UNPACKING AND INSPECTION

Modular Cuber

1.

Call your authorized SCOTSMAN Distributor

or Dealer for proper installation.

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) Remove the packing nails securing the

carton box to the skid.

c) Cut open the top of the carton and remove

the polystyre protection sheet.

d) Pull out the polystyre posts from the

corners and then remove the carton.

4.

Remove 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.

Loose two nuts on left and rights side of the

unit base and remove it from the skid. Save the
two bolts and nuts to mount the machine on
storage bin or on top of another Modular Cuber.

GENERAL INFORMATION AND INSTALLATION

6.

Remove all internal support packing and

masking tape and the hardware package.

7.

Check that refrigerant lines do not rub

against or touch other lines or surfaces, and that
the fan blade moveS freely.

8.

Check that the compressor fits snugly onto

all its mounting pads.

9.

See data plate on the rear side of the unit

and check that local main voltage corresponds
with the voltage specified on it.

CAUTIONIncorrect 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

LOCATION AND LEVELLING

WARNING. This Ice Cuber  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 Bin 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 Storage Bin Assy in both the left

to right and front to rear directions by means of
the adjustable legs.
