UNPACKING<br />
The machines are<br />
supplied in a carton box<br />
secured by two plastic<br />
strips to a wooden base.<br />
Check first the outside<br />
conditions of carton box<br />
and wooden base then cut<br />
the two plastic strips,<br />
remove the tape and then<br />
the carton box. <strong>MV</strong> <strong>306</strong>

UNPACKING<br />
The Modular Cuber machines<br />
require for the installation the use of<br />
a companion storage bin to store the<br />
ice produced.<br />
Storage bins required are:<br />
• B 193 for <strong>MV</strong> <strong>306</strong><br />
• B 393 for <strong>MV</strong> <strong>456</strong>-<strong>606</strong>-<strong>806</strong>-<br />

INSTALLATION<br />
The installation of the<br />
metal plate (air<br />
separator) grants also a<br />
minimum distance<br />
between the back side of<br />
the machine and the wall<br />
so to assure a correct and<br />
adequate ventilation.<br />

Check the data<br />
plate of the<br />
machine located on<br />
the rear panel for<br />
correct voltage as<br />
well as for the<br />
proper wiring/fuse<br />
size.<br />
Remember that all<br />
machines require a<br />
solid earth wire.<br />

INSTALLATION - ELECTRICAL<br />
Install, on the cable supply<br />
with the machine, an<br />
adaguate electrical plug<br />
according to the local<br />
standards and regulations.<br />
Maximum voltage variation<br />
should be ±10%.<br />
Machine must be<br />
individually fuse protected.

Connect the water inlet 3/4”<br />
male threat of the water inlet<br />
fitting to the water supply line<br />
by means of the rubber hose<br />
provided with machine.<br />
Install on water supply line<br />
closed to the machine a water<br />
valve (tap).

Connect the 20<br />
mm O.D. fitting<br />
of the water drain<br />
with the flexible<br />
hose supply with<br />
the machine with<br />
its proper clamp.<br />
As water will be<br />
mainly drained<br />
under pressure<br />
(by water pump)<br />
it is not necessary<br />
to have a vented<br />
drain.
