4 INSTRUCTIONS FOR TECHNICAL STAFF
4.1 lumbing hookup
Water supply and drain connection
The water pipelines and electricity supply cable lead out of the bottom
ri ht-hand corner of the appliance. Connect the water intake hose to a
connector with ¾” threaded fittin , fittin the filter A provided (in models
with acquastop, the filter and rin -nut form a sin le unit).
The connection to the water mains must only be made with new hoses; the
use of old or worn hoses is not permitted.
FOR MODELS WITH A WATER SOFTENER
AN ‘APPROVED’ DOUBLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING
BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE
POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE.
FOR MODELS WITHOUT A WATER SOFTENER
AN ‘APPROVED’ SINGLE CHECK VALVE OR SOME OTHER NO LESS EFFECTIVE DEVICE PROVIDING
BACKFLOW PREVENTION PROTECTION TO AT LEAST FLUID CATEGORY TWO SHALL BE FITTED AT THE
POINT OF CONNECTION BETWEEN THE WATER SUPPLY AND THE FITTING OR APPLIANCE.
The dynamic water supply pressure must be between 1 and 6 bar; if it is hi her a pressure reducer
must be installed. It is essential to fit a main stop tap on the water intake deliver pipeline; the tap
must be accessible after installation of the appliance, so do not install it behind the warewasher. The
stated cycle duration applies to appliances supplied with hot water >50°C<60°C If the warewasher is
supplied with cold water, the cycle duration mi ht increase dependin on the intake water
temperature. The warewasher is fitted with a drain pump and can operate with drain connections
on the floor or wall. Refer to the connection dia ram for the maximum permitted hei ht of wall
drains – (see TECHNICAL DATA)
Caution: the indoor system and premises in which equipment for institutions is installed
must comply with the relevant re ulations.
The manufacturer declines all liability for direct or indirect injury or dama e derivin from failure
to comply with these re ulations. Before installation, check that there are no objects or materials
in the vicinity which may be dama ed by steam or splashes of washin solution, or that any such
items are suitably protected. Place the lasswasher in the chosen point and remove the protective
film. Level the lasswasher (with the aid of a spirit level) on its adjustable feet to ensure that it is
stable; all other mountin solutions must be approved by the manufacturer.

8
Caution: make sure that the intake and drain hoses are not bent, constricted or crushed
after installation.
When installin the drain hose to a siphon with valve, the maximum hei ht of the drain outlet is
reduced to 600 mm.
4.2 Electrical connection
The glasswasher and any additional equipment must be connected to the electrical
system by authorised, skilled staff, in accordance with the relevant re ulations; also
comply with the technical instructions for the connection.
The total rated power is stated on the appliance’s technical data plate.
The electrical protection devices fitted for the lasswasher must serve this appliance
only.
The user must have a master switch and a differential safety breaker, with rating
suitable for the appliance’s characteristics, installed on the electricity supply line in
accordance with the relevant regulations.
These switches must be installed close to the lasswasher, be easily accessible after
installation, and provide complete disconnection from the electrical mains in
overvolta e class III conditions.
Warning !!!
The lasswasher is always powered up unless the master switch is turned off.
Connect the appliance to the user’s earth system. The terminal for the connection is
in the bottom ri ht-hand corner of the appliance.
The earth wire (PE) is yellow- reen in colour, the neutral wire (N) is blue and the live
wires (L1, L2, L3) are black, rey and brown.
In the event of sin le-phase connection (230V-1N~), the connection to the electrical
mains must be made usin a cable with plu compliant with the relevant regulations.
THE POWER SUPPLY CABLE, AS PROVIDED, MUST BE REPLACED BY THE
MANUFACTURER OR AN AUTHORIZED SERVICE CENTER IN COMPLIANCE WITH THE
SPECIFICATIONS PROVIDED ON ELECTRICAL DIAGRAM SUPPLIED IN THE MACHINE IN
ORDER TO PREVENT ALL RISKS.

9
5 FIRST START-UP
First start-up
The electrical protection system must under o a functional test before the appliance is put into
operation.
The appliance must be installed and/or inspected by qualified staff, who will start it up for the first
time and provide the relevant operatin instructions.
Preparing for use (important)
The rinse aid dispenser is fitted on all models, the deter ent dispenser only on some.
If both dispensers are present put the external deter ent and rinse aid containers in place and
insert the respective intake hoses on the rear of the appliance into them.
Red hose: deter ent
blue hose: rinse aid
NOTE: It takes about 10-15 wash cycles before they arrive in deter ent and rinse tank and boiler
Before insertin the hoses into the containers, fit the wei hts (needed
to ensure that they always draw in liquid from the bottoms of the
containers) and the filters onto their ends as shown.
If the deter ent dispenser is not factory-fitted, it can be retrofitted
after orderin the relative kit.
As an alternative an external dispenser can be fitted, makin the electrical connection by means of
an H05 RN-F 2x0.5 mm electrical cable, which can be laid alon the route shown in the TECHNICAL
DATA dia ram and connected as shown in the wirin dia ram supplied with the lasswasher.
The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.
Connect to the deter ent dispenser outside the lasswasher usin the red hose mentioned above.
5.1 Using the water softener (on models with this feature only)
The quantity of lime in the water (which indicates its hardness) causes whitish
marks on dry dishes and dishes also tend to lose their shine over time.
The lasswasher is equipped with an automatic water softener which removes
the substances that cause hardness from the water with the aid of re eneratin
salt.
The first time the lasswasher is used, a litre of water must be poured into the
tank with the salt. Whenever the tank is filled, always take care to ensure that the
cap is firmly closed.
The mixture of water and deter ent must not et into the salt tank, as this would
impair operation of the re eneration system.
In this case warranty cover will be forfeited.

IMPORTANT:
Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out
the peristaltic pumps by placin the external intake pipes in water for a few cycles. Always use
only products specifically recommended for use in a lasswasher. Failure to comply with this
recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system.
The internal pipes of the detergent and rinse aid pumps should be replaced by the After-Sales
Service every 12 months or 15,000 wash cycles and operation of the diaphra m can be disposed
of in accordance with the relevant re ulations rinse aid pump should be checked.

that the rinse aid peristaltic pump fills the circuit in about 7
minutes, while for the deter ent it only takes 2 minutes. So
draw only rinse aid from the jerry cans (1 for the rinse aid
and the other for the deter ent) for the first 5 minutes and
then also take in deter ent for the last 2.
7 MALFUNCTIONS SHOWN ON THE DISPLAY (FOR
THE TECHNICIAN)
The lasswasher is able to identify a number of malfunctions and show them on the display. If the
problem persists after the lasswasher has been switched off and back on, proceed as described below:
Err01
The anti-floodin system has
been activated (for the
relevant models only).
Lar e water leak: check the ori in of the problem.
Err04
Tank temperature probe
malfunction
Tank temperature probe disconnected or not workin .
Err05
Tank water fillin malfunction The tank does not fill within the allowed time: check water intake
tap, dynamic pressure in intake system, cleanin of water intake

17
filter, possible dama e to water intake hose or cleanin of rinsin
nozzles. If the problem persists durin FILL:
- tank pressure switch has failed (continuous empty readin : check
whether tank safety pressure switch is tripped)
- leak from pipe connected to air trap
If the problem occurs durin work cycle
- filler hose bleeder valve fouled: tank empties completely at end
of a wash cycle due to siphon effect.
Err06
Water pump-out malfunction
Inspect the filters for dirt and check that the drain hose is not
blocked, bent or crushed.
Check that the drain pump is not blocked by dirt by removin the
insert on the sump (from inside the tank).
If it persists, check in this order:
- with tank empty: constant “tank full” si nal: tank pressure switch
faulty or leak from connections of air trap connection pipe (water
enterin pipe)
- with tank full: drain pump failure
Err09
Too much water in tank
With tank full:
see above (water pump-out malfunction)
With tank empty: constant “tank full” si nal: safety pressure switch
faulty or leak from connections of air trap connection pipe (water
enterin pipe)
Err23
Boiler does not heat up as
expected
The problem mi ht occur because water is continually enterin the
tank (the causes are as for Err5 – see above)
If it persists, check in this order:
- dama ed boiler heatin element
- contactor failure,
- boiler safety thermostat failure,
- boiler temperature probe faulty or incorrectly positioned
- motherboard relay failure,
Important: if the boiler heatin element is dama ed, this mi ht be
due to operation with no water in the boiler - the pressure switch
is indicatin full even with the boiler empty: check and if necessary
replace the boiler air trap and/or the relative pressure switch: the
problem is enerally preceded by “boiler overheatin E28”
Err24
Boiler temperature probe
malfunction
