52
INSTRUCTIONS FOR TECHNICAL PERSONNEL
2)WATER CONNECTION
Install a 55°C water tap in a well accessible place, terminating in a 3/4 " fitting,
which the pipe strainer and inlet hose shall be connected to. Carefully comply
with any national or regional regulations in force. The operating pressure
should be neither less than 2 bars or greater that 4 bars (200/400 kPa). If
water pressure is inferior then 2 bar, a pressure increase pump is necessary. If
water pressure exceeds 4 bar, a pressure reducer is necessary.
In order to obtain best results, it is suggested that the water supply have a
hardness not greater that 15°F.
3)WATER DRAIN
Arrange a water drain towards the floor with siphon and connect the machine
with the flexible tube given with the machine, so that it leans towards the drain.
Moreover, make sure that the hose does not have constrictions. Make sure
that the building drain tubing withstands temperatures up to 70°C.

Marks can be caused by an insufficient rinse: in this case check that the rinse
nozzles are clean and that there is sufficient water supply pressure.
In case of dishware residue check that:
?? the washing nozzles are clean
?? the water temperature is around 60°C
?? there is detergent
?? the pump suction filter is clean
?? the racks are suitable for the dishes and cutlery that are to be washed
?? the position of the cutlery and the dishes in the racks are correct
3) TEMPORARY MACHINE NON-USE
In case the machine is stopped for some weeks, it is recommended before
closing it to fill the tank and run the machine with clean water, then empty it
out, in order to avoid the forming of bad odour and that any residue remains
in the pump.
If necessary repeat this operation until the water leaving the machine is clean.
If the machine is stopped for many weeks, it is recommended to oil the
stainless steel surfaces with paraffin oil and to discharge the water from the
boiler and the electric pump.
4)SANITISING THE MACHINE
Sanitising the machine at least once a week is of the utmost importance in
order to guarantee hygiene even when the machine is not in use.
It is advisable to use a disinfecting product suggested by an authorised
detergent dealer.
The use of this product will satisfy hygienic requirements, even during
machine non use.
Before switching off the machine run the machine briefly with clean
water.
5)HARD WATER CONDITIONS
If a hard water supply is present, mineral deposits will form within the machine
and also on dishware.
In order to avoid the above conditions a periodic removal of these deposits is
necessary.
The frequency and method of this operation upon consultation by your
detergent supplier.

INSTRUCTIONS FOR TECHNICAL PERSONNEL
INSTALLATION
During installation, carry out proper machine levelling, which is a prerequisite
for a correct operation thereof (max. tolerance 2°).
In order to prevent any damage caused by steam going out of the machine,
make sure that the surrounding materials do not deteriorate in its presence.
00
After machine installation check thermostat settings, booster 85°C, tank 60°C.
1)ELECTRICAL CONNECTION
The electrical safety of this equipment is only assured if it is connected as
follows.
It is necessary to connect the equipment to an effective earthing as specified
by the electrical safety regulations in force. Check that this basic requirement
is complied with, in case of any doubt ask for a careful check of the
installation by a qualified personnel.
In the case the earthing is not efficient there will be a dispersion due to the
suppresser.
The machine shall be included in a correctly dimensioned equipotential, whose
effectiveness is to be very tight in accordance to the procedures set for in the
applicable safety standards. The connection shall be performed through a
screw marked by a plate near the rear
side of the appliance.
The manufacturer declines any responsibility for any damages caused by lack
of an effective ground installation. For the electrical power supply have
available a wall circuit breaker switch with multiple phase protection according
the following table with contact aperture distance, equal to or not exceeding
3mm and a supply cable no less than 2.5mm?.

For other supplies the cable cross section and the circuit breaker switch must
be calculated according to voltage and length of cabling. If cabling too long
adjust cable size to Amp rating; do not pull on supply cable or install it under
tension. If cable needs to be replaced use type H07RN-F.

INSTRUCTIONS FOR TECHNICAL PERSONNEL
2)WATER CONNECTION
Install a 55°C water tap in a well accessible place, terminating in a 3/4 " fitting,
which the pipe strainer and inlet hose shall be connected to. Carefully comply
with any national or regional regulations in force. The operating pressure
should be neither less than 2 bars or greater that 4 bars (200/400 kPa). If water
pressure is inferior then 2 bar, a pressure increase pump is necessary. If water
pressure exceeds 4 bar, a pressure reducer is necessary.
In order to obtain best results, it is suggested that the water supply have a
hardness not greater that 15°F.
3)WATER DRAIN
Arrange a water drain towards the floor with siphon and connect the machine
with the flexible tube given with the machine, so that it leans towards the drain.
Moreover, make sure that the hose does not have constrictions. Make sure
that the building drain tubing withstands temperatures up to 70°C.
4)RINSE AID DOSAGE
Make sure that rinse aid suction hose is correctly installed in it's proper
container.
Adjusting the dose:
-regulate by means of the screw , turning clockwise (-) to decrease the
quantity or anticlockwise (+) to increase it.
Start the machine (as described in paragraph OPERATIONS AND USE).
Fill during the wash cycle by opening (slightly) and closing the door
until the hose has completely filled.
At this point the machine automatically takes the necessary liquid for every
rinse: during the washing operations, check that the liquid of the container
does not run short.
Make some empty cycles, then try to wash: if the objects washed show some
drops, this means that the rinse aid is insufficient. On the contrary, the
presence of marks can mean that there is too much rinse aid or the water is
too hard. The regulation can change according to the kind of rinse aid.
5)DETERGENT DOSAGE (for machines with built-in detergent dispenser)
With the screw on the side of the detergent pump, close completely the
product intake, then slowly open the screw until the desired intake quantity has
been reached. The correct quantity is indicated by the detergent supplier.
Check that the intake of the pipe during the rinse cycle is as preset. (8cm = 1g
approximately). Maximum intake or delivery distance: 2 meters.
