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 regarding
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 dining facilities. Therefore, installation, use and
maintenance must in all cases be performed by trained personnel who follow the
manufacturer’s instructions. Do not leave within the reach of children. The choice of
materials, construction in conformity with EC safety directives and complete testing ensure
the quality of this machine.
The manufacturer declines all responsibility for damage to property 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 is 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.
For Australia this machine must be installed in accordance with AS/NZS3500.1
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 it 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.
•Different 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 at 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 close to the
place of 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 section 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 gate 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 just before the appliance.
•If the system is new or nearly so, let the water 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 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 in any
way
.
•The tank empties by gravity, so the drain must be at a
lower level
than the base of the machine (s25mm).

With discharge pump (available
on request)
•If the drain is not at a lower level than the base of the machine, you
can use the version equipped with a discharge pump (available on
request).
•In this case the maximum drain height is 710mm.
•Always check that the drain works properly and that it is not clogged.
•All other solutions must be previously agreed upon and approved by
the manufacturer.
2.6 Rinse aid and detergent
•Rinse aid is dispensed by the hydraulic dispenser installed standard on the
machine.
•Dispensing of detergent is manual, even if installation of an automatic dispenser
is always recommended.
•Dispensing is established based on water hardness by the installation
technician, who will also calibrate the dispensers.
•The level of liquids in the container must be high enough that it can be
drawn. It must never empty completely, or be topped off with corrosive or
impure products.
