Chap 1 PREFACE
Failure to follow the instructions provided in the attached documentation may jeopardize
safety of the appliance and immediately cancel the warranty.
The warnings contained in this manual provide important information r
egarding
safety during the various installation, operation and maintenance stages.
Carefully store all documentation near the appliance; give it to the technicians and operators who
will be using it. It is the operator’s duty to read, understand and learn
this manual before
starting any operation on the machine
. The appliance is intended for the professional washing of
dishes for communities, so installation, use and maintenance must in all cases to be performed by
trained personnel who follow the manufact
urer’s instructions. Do not leave within the reach of
children. The choice of materials, construction in conformity with CE safety directives and complete
testing ensure the quality of this machine. In addition to this manual, you will find in the machine:
•wiring diagram
•topographic table
The manufacturer declines all responsibility for damage to things or injuries to persons
deriving from failure to comply with the instructions given or from improper use of the
machine.
Chap 2 INSTALLATION
Proper installation i
s essential in order for the machine to operate well. Some of the data needed for
machine installation can be found on the data plate placed on the right side
of the machine and in
duplicate on the cover of this manual.
Only qualified, authorised technicians must install the machine.
2.1 Unpacking
Check that the packing is in perfect condition and write down any damage found on the delivery
note. After you have removed the packing, make sure the appliance is intact. If the machine
is
damaged, immediately notify the dealer by fax or by registered letter with advice of receipt and the
haulage contractor that transported it. If the damage is such as to jeopardize machine safety, do not
install and/or use until a qualified technician services it.
The packing components (plastic bags, foam polystyrene, nails, etc. ...) must not be
left within the reach of children and pets as they may be dangerous.
2.2 Positioning
•Check that there are
no objects and materials in the
installation area that can be damaged by steam that
may exit the machine during operation, or at least
that they are sufficiently protected.
•
In order to ensure stability, install and balance the
machine on its four feet.
•Dif
ferent installation solutions must be agreed upon
and approved by the manufacturer.

2.3 Electrical connection
•
There must be an omnipolar type of main switch
that disconnects all contacts, including the
neutral, with a distance of a
t least 3 mm between
the open contacts and with safety circuit breaker
tripping or connected with fuses
, to be sized or
calibrated in conformity with the power indicated on
the machine’s data plate.
•
The main switch must be located on the electric line
clos
e to the installation, and it must serve only one
appliance at a time.
•
Electric network voltage and frequency must
coincide with those given on the data plate.
•
There must be an effective earthing system in
conformity with the prevention standards in force
for
operator and equipment safety.
•The power supply cable (type H07RN-
F only) must
not be pulled or crushed during normal operation or
routine maintenance.
•
The unipotential terminal fastened to the body must
be connected to a unipotential cable having a se
ction
suited to the application.
•
Respect the polarities indicated in the wiring
diagram.
•
Consult that attached wiring diagram for additional
information.
Do not use adaptors, multiple socket-outlets or cables of inadequate type
and
section or with extension connections not compliant with plant engineering
standards in force.
2.4 Plumbing connection
The appliance is to be connected to the water network
with a hose. There must be a slide on-off, ball or ga
te
valve
able to quickly and completely turn off the
water if necessary
between the water network and the
appliance’s solenoid valve. The on-
off valve must be on
the line near and right before the appliance.
•If the system is new or barely used, have the w
ater run a long time before making the
connection.
•The water supply, temperature and pressure must be compatible
with what is indicated on the
machine’s technical data plate.
•If the water’s hardness is greater than 14 F (8 dH), we recommend you use the mac
hine with
internal water softener (available on request
). If the water’s hardness is greater than 35 F (19.5
dH), we recommend you install an external water softener upline of the solenoid valve.

Free drain
2.5 Connection to the drain line
•
The drain line must be made up of a free water
trap
of a size proportionate to the delivery of the
drain pipe supplied with the machine. The pipe must
be able to reach the water trap
without being
pulled, squeezed, bent, crushed, pressed or
forced by anything.
•
The tank empties by gravity, so the drain must be at
a lower level than the base machine.

and similar items slanted on dedicated ra
ck with
internal surface facing upwards. Accommodate all
silverware in the supplied basket with handles-down.
•Wash only items approved for dishwashing.
•
