CHAP.1 INTRODUCTION
The warnings contained in this manual provide important
information for safely installing, using and servicing this
machine.
The operator is required to read this manual before starting
any operation involving handling, installation, use,
maintenance or disassembly of the machine. This manual
must be kept intact and in a safe place for frequent
consultation.
CHAP.2 INSTALLATION
2.1 HANDLING AND UNPACKING
xMove the machine very carefully using a forklift.
xMake sure the equipment is not damaged, if it is immediately
inform the dealer and shipper. If in doubt do not use the
machine until it has been checked by professionally trained
personnel.
xMove the machine to the site where it will be used and
remove the packing.
Packing materials (plastic bags, polystyrene,
nails) can be dangerous and must be kept out of
the reach of children.
xThe installation must be carried out according to the
manufacturer’s instructions and by professionally trained
personnel.
xOnly a fixed connection is suitable for this equipment.
xPosition the machine and level it perfectly using the feet.
xThe flooring must be suitable for the overall weight of the
machine.
xFollow the indications on the installation drawing and set-up
the electrical, water and drain systems in the wash area.

Pag. 4 GB
2.2 ELECTRICAL CONNECTION
1. Connection to the power supply must be made with a main
switch (H) it must be omnipolar and interrupt all contacts
including neutral. There must be a distance of at least 3
mm between open contacts, and it must have a thermal
magnetic safety switch or fuses which are able to
withstand the maximum power indicated on the plate.
2. Make sure that the power supply corresponds to that on
the technical features plate on the right side of the
machine.
3. Use an effective earthing system in compliance with local laws to
protect the safety of the operators and not damage the machine.
4. Do not use adapters, multiple sockets or extension cords.
5. The equipment must be included in an equipotential
system, and connected using a screw marked with the
symbol. The equipotential wire must be 10 mm² .
If the power supply cable (provided with the equipment) needs to
be replaced use another H07RN-F type with the same dimensions.
For additional information see the wiring drawing.
2.3 WATER CONNECTION
Set-up the site according the attached plumbing drawing.
Before connecting the equipment make sure that a gate valve
has been placed between the water supply and the
equipment so that the water can be turned off if required or
for repair work.
Use a hose to connect the solenoid valve (E) to the gate
valve (V) and make sure that the delivery is not less than
20l/min.
Check that the temperature and water pressure correspond to
what is shown on the technical specifications plate.
If the water is harder than what is listed in the chart, it is
advisable to install a decalcifier upline from the solenoid
valve.
If there are high concentrations of very conductive minerals
in the water, it is advisable to install a demineralization
system calibrated to the hardness shown in the following
chart.

2.4 CONNECTION TO THE DRAIN LINE
The tank empties by gravity, so the drain needs to be
situated below the base of the machine.
The drain pipe needs to be connected to a drain- trap built
into the floor.
The drain dimensions are shown in the installation drawing.
2.5 ADJUSTMENTS AND CHECKS
The temperature of the wash tank is regulated by a fixed thermostat at
about 55° C. This temperature ensures proper action by the chemicals
contained in industrial dishwashing detergents.
The boiler temperature set by a fixed thermostat is about 85° C.
2.6 RINSE-AID DISPENSER (optional)
Before adjusting, the dispenser and hose need to be filled
using the primer button (A).
To adjust use the ring nut (B) situated at the center of the
dispenser, rotating clockwise reduces the quantity,
counterclockwise increases it.
The dispenser must not operate empty
An excessive amount of rinse agent causes bluish stripes on the
dishes and creates foam in the wash tank.

If the glassware is covered with droplets of water and it dreis rather
slowly this means that the amount of rinse agent is insufficient.
7 cm. of tubing = 1 gram of product
2.7 DETERGENT
Equipment without a detergent dispenser
Put the amount of detergent recommended by the
manufacturer into the tank. Depending on the type of
detergent this may vary from 2 to 4 gr/lt of water in the tank.
Detergent needs to be added approximately every 5 washes
as per the manufacturer’s instructions.
The above amounts are for water with a hardness of 5-10°F
(French degrees).
Machine equipped with detergent dispenser (optional)
Regulations:
A trimmer (A) allows to determine the «ON-OFF» time and
consequently the amount of detergent required.
xTurning the adjustment trimmer clockwise or counter-clockwise will
respectively decrease or increase the amount of rinse aid it
delivers.
xTo optimise the calibration, evaluate the results of some washing
cycles.
BE CAREFUL!
The level in detergent tank must not get empty or filled with corrosive
or inadequate products.
The warranty does not cover damages caused by an improper use of
dispenser.
CHAP.3 SAFETY RECOMMENDATIONS
3.1 RESIDUAL RISKS AND WARNINGS
xNever open the door quickly if the cycle has not finished.
xDo not put bare hands into the wash solution.
xNever remove the machine panels if the power upline has not been turned off.

xThe professionally trained personnel who install the machine and connect the electricity,
will explain to the user how to operate the machine and which safety measures to use.
xThe installer will provide practical demonstrations and leave written instructions which are provided with
the machine.
xThis machine is only to be used for the purpose for which it was designed.
Any other use is considered improper and dangerous.
xThe machine is not to be used by untrained personnel.

4.2 USE OF THE MACHINE
xPour the proper amount of detergent in the wash tank according to
the producer’s instructions.
xThe detergent must be the industrial type or possibly
foamless.
xNever put your bare hands in the wash water; place the cups and
the glasses upside down in the baskets. Place the dishes in the proper
basket with support pins and their inner surface must be facing up.
xPlace the silverware and the coffee spoons with the handles facing
down.
xNever place silverware and stainless steel cutlery in the same
basket. This could cause the silver to burnish and the stainless steel to
corrode.
xUse the proper baskets specifically designed for the different type
of glassware (dishes, glasses, cups, silverware etc.). To save on
detergent and electricity only wash when the baskets are full, but do not
overload them. Avoid stacking glassware.
xWE RECOMMEND TO PRE-CLEAN the glassware in order to
minimize maintenance. The quality of final wash results will be greatly
improved by first removing food particles, lemon peels, toothpicks, olive
pits, etc. which could partially clog the pump filter and impair washing
efficiency.
We recommend washing the glassware before food particles dry
on its surface. It is good practice, when dried food waste is
involved, to first soak the glassware and silverware before
introducing them into the machine.

4.3 FINAL OPERATIONS
xRemove tension from the machine.
xOpen the door and remove the rack with clean dishes.
xDrain the water from the tank by lifting the overflow-pipe. For the
model with drain pump please follow the operations described in the
«Use instructions» paragraph.
xDisconnect the main switch of the equipment.
xClose the «rolling shutter valve» for the hydraulic connection.
xRemove the filters clean them under a water jet with a nylon brush.
xPay attention not to let any dirtiness rests on the bottom of the
drain pump filter inside the tank. Clean the tank with a moderate water
jet. Wash outside surfaces when are cold with non-abrasive products
which are especially studied for steel maintenance.
REMARK: Do not wash the equipment with direct jet or at
another pressure because eventual infiltrations to the electric
components may harm the regular working of the equipment or
of the single safety systems, and penalty for this would be the
loss of guarantee.
