TOPICS

On the next slides are shown the following steps by steps
procedures:

• UNPACKING

• INSTALLATION

• START UP AND OPERATIONAL CHECKS

• OPERATING PRINCIPLES and COMPONENTS

• MAINTENANCE

• SERVICE ANALYSIS

NEW MXG SERIES

UNPACKING

NEW MXG SERIES

The machines are supplied
in a carton box secured by
two plastic strips to a
wooden base. Check first
the outside conditions of
carton box and wooden base
then cut the two plastic
strips, remove the tape and
then the carton box.

frame from

the wooden

base….

The Modular Cuber machines
require for the installation the
use of a companion storage
bin to store the ice produced.

Perfect “matching” storage
been are:

SB 193 – 322 for MXG 328-428
SB 393 – 530 for MXG 438-638-938

UNPACKING

NEW MXG SERIES

Due to design reason MXG
series can not be stacked:

• Ice chutes not aligned

• Not enough space for
Service over the bottom unit
top evaporator

• Not possible to remove
bottom unit front panel

UNPACKING

NEW MXG SERIES

INSTALLATION

NEW MXG SERIES

After having installed the
ice maker on top of chosen
bin, remove polystyrene
block form ice chute top
and remove the ice chute.

locate I/R and its bracket,
release the same from
clamps

INSTALLATION

NEW MXG SERIES

Cut the unit base
gasket , pass the
I/R sensor through
the same reaching
the inner bin area.

INSTALLATION

NEW MXG SERIES

Fix the IR
by
supplied
screws to
related
bracket

INSTALLATION

NEW MXG SERIES

Fix IR bracket at
ice chute
discharge area by
stainless steel
screw

INSTALLATION

NEW MXG SERIES

Once installed optical level
sensor, re-install ice chute
previously removed paying
attention to hang the same
to its hook rim point.

INSTALLATION

NEW MXG SERIES

Note different
location
according to
MXG models

INSTALLATION

NEW MXG SERIES

MXG 328-428-438-938

MXG 638

Check the data plate
of the machine
located on the rear
panel for correct
voltage as well as
for the proper
wiring/fuse size.

Remember that all
machines require a
solid earth wire.

INSTALLATION

NEW MXG SERIES

Check for the correct water and ambient conditions that
should be:

• Min. ambient temperature 10ºC (50F)

• Max. ambient temperature 40ºC (100F)

• Min. water temperature 5ºC (40F)

• Max. water temperature 35ºC (90F)

• Min. water pressure 1 bar (14 PSI)

• Max. water pressure 5 bar (70 PSI)

INSTALLATION

NEW MXG SERIES

Adequate space must
be left for proper water
and electrical
connections on the rear
side of the machine. A
minimum clearance of
15 cm on both sides for
best routing air.
