WARNINGS:
Once installation is complete, it is recommended to detach the installer’s guide section of
this manual for future reference.
1. MACHINE INSTALLATION
1.1 Receiving product
After removing the packaging, make sure that the apparatus was not damaged during tran-
sportation. If this should be the case, notify the seller of the defect. For packaging disposal
see chap. 9.
1.2 Water connection
Connect the machine water supply with a stop valve that can quickly and completely
turn off water ow.
Make sure that the water supply system is within the parameters reported in tab. 1.
If the water system pressure is above 4 BARS (400 KPa), a pressure reducer is recom-
mended.
It is compulsory to install a water-softner for water with average hardness above
10°f.
Dishes/objects will be cleaner and the machine will last longer.
Each machine is supplied with a rubber water load tube with a 3/4"F threaded connection.
It is recommended to connect the tube to water supply systems that do not exceed 55°C,
if connected to hot water.
Connectthe suppliedmachinedrainingtubetotheconnectorlocatedunderthetank,making
sure that the water ows freely (giving, therefore, minimum slope).
The drain tube shall always be connected to a siphon (Ø) in order to prevent the release of
odours. The MAXIMUM drain permitted height is 10cm.
1.3 Electrical connection
The electrical connection shall be carried out in accordance to the laws in force.
Make sure that the line voltage is the same as that written on the machine plate. Apply a
suitable magneto-thermic omni polar switch measured in accordance to absorption
and that is equipped with a contact opening of at least 3 mm (always turn the machine
off with this switch). This is the only switch which guarantees total electric supply
system isolation.
This switch shall be solely and exclusively used for this purpose and installed in the imme-
diate vicinity.
Make sure that the facility is equipped with efcient grounding.
Moreover, the machine has a clamp at the back indicated by the symbol (see g. 1) that is
used for equipotent connection among different apparatuses. The maximum power expresses
in watts (W) and amperes (A) is located on the serial number plate for line measurement,
cable and switches.
N.B.: for machines cable types H05RN-F or H07RN-F must be used or replace with
others which correspond to the regulations of the country where the ware-washer is
installed. A 4mm² section for voltage 380-415V3~, and a 6mm² section for voltage
220-240V3~. The replacement of the cable must be carried out by specialized
personnel only.
The seller/importer/installer must adapt the supply cable isolation class in function to the
work environment respecting the Technical Regulations in force.

Proceed to machine start-up and rinse aid dispenser calibration as follows:
1) Turn on the wall switch and the water tap.
2) Turn on the ware-washer by pressing key (B) (see par. 2). The relevant green led will
come on.
3) The machine begins to load water in the boiler and the tank (it is important to not open
the door).
4) Once water is loaded, it is heated in the boiler then subsequently in the tank.
5) It is already possible to verify correct pump rotation pressing the START key, since, being
tri-phase, it can rotate the other way. In addition to the orientation arrows, this is also
indicated by excess noise during the wash cycle (see g. 2).
Important: improper pump rotation can cause impeller unscrewing and rotary seal water
leakage.
6) The machine is ready for washing.
The machine’s sound level is LpA= 82dBA± 2.5. **
**test made according to EN 60335-2-58/A11
1.4 Rinse aid dispenser operation
Dispenser operation g. 3:
Use the rinse pressure pump to withdraw from the canister and inject the rinse aid into the
boiler during the wash phase.
Water connection (for replacement only):
1) Use the rubber tube installed on the machine to hook up the dispenser to its connector
(B) with the special connector located near the boiler (injector).
2) The green tube, on the other hand, which comes out of the suction connector (C), shall
be inserted with a small lter and relevant ballast, in the rinse aid product withdraw
canister (during use).
The connector “A” shall be hooked up to the rinse circuit with a “T” connection.
Initiation:
For initiation simply start the machine and carry out a few wash and rinse cycles.
Regulation:
During each cycle the dispenser withdraws an adjustable quantity of rinse aid product from
0 to 4 cm3equivalent to the suction length in the tube from 0 to 30 cm.
The minimum ow is obtained by completely screwing the regulation screw (D) (clockwise),
while maximum ow is obtained by unscrewing the regulation screw with about 20 rotations
(counter-clockwise).
For proper chemical product dosage see the product manufacturer notes (see also par.
7.4).
N.B.: for each screw rotation the rinse product dosage varies from 1,6 cm sucked into the
tube, equal to 0,2 cm3/rotation (about 0,21 g/rotation with product density of 1,05 g/cm3).
The rinse aid dispenser cannot function properly is there is a slope of over 40 cm
between the bottom of the machine and the canister.

7.1 General operation
The machine needs 3 connections to run:
• Electric;
• Water supply;
• Drain.
The machine is designed with a wash chamber inside which there is:
• A basket support, connected to a clutch equipped gear, where the rack is placed to rotate
during the wash cycle.
• Two interchangeable wash arms where water and water mixed with granules ow from.
• A rinse arm connected to a pump which withdraws from the boiler guaranteeing constant
temperature rinse ("Plus" system).
• A lter located under the chimney to prevent granules from rising and getting stuck in the
fan located at the end of the chimney.
A tank is found under the chamber which contains water in one part and water mixed with
granules in the other. The part containing water shall always be covered by blind chutes to
avoid granule contamination.
The part containing the granule water mixture shall always be covered by work perforated
lters or, in the granules recuperation phase, the collection strainer with special lateral
compensatory chutes (see chap. 7.7).
7.2 Machine preparation
• Prepare the right amount of granules by lling the strainer to the indicated level (see
photo 1).
• Pour the contents into the right-hand side of the tank.
• Place the overow tube in the dedicated seat, at the tank bottom.
• Insert the two chutes above the water-only area (left-hand side of the tank) and the two
perforated lters above the granule area (right-hand side of the tank).
• The lters shall be cleaned every 15-20 cycles and whenever necessary. Do not use
the machine without lters.
• Make sure that the wash and rinse arms are properly placed.
• Make sure that the rack support is inserted properly.
• If the machine is equipped with a detergent dispenser, insert the transparent hose into
the detergent canister.
• Insert the special green rinse-aid chemical container and check that the quantity is
sufcient for the workload of the day.
• Shut the door.
• Open the water valve, activate the main wall switch and proceed with turning on the
machine by pressing key “B” (see g. 7). The green led will come on. After a few seconds,
the lling stage shall begin.
• After water-lling, the machine will automatically activate the heating stage.
• The machine shall be ready for washing, only when the boiler and tank thermometers
indicate that the proper temperatures have been reached: 80-85°C for the boiler and
50-55°C for the tank.
• Insert the rack with the various objects to wash and shut the door.
• Before beginning the wash cycle, insert the proper detergent into the tank (if the machine
is not equipped with an automatic dispenser).
• Select the wash cycle time using the keys (C/D) and the type of wash cycle (only water

7.9 H.A.C.C.P. and hygiene regulations
• The machines are equipped with temperature displays that indicate boiler and tank
temperature. It is recommended to wait until the set temperature is reached.
• Rinse all objects to be washed carefully to avoid obstruction of lters, nozzles and
piping.
• Drain the wash tank and clean the lters at least 3 times a day.
• Check that the detergent and rinse-aid dosage are correct (as recommended by the
manufacturer). In the morning, before using the machine, check that the quantity of
product in the canisters is enough for daily supply.
• Keep dish table clean.
• Extract the dishwasher basket with clean hands or gloves to avoid nger marks.
• Do not dry or polish the clean objects with cloths, brushes or rags that are not sterile.
7.10 Pressure increase/rinse pump
Aftera periodofinactivityoftheware-washer, thepressureincrease/rinsepumpcanbecome
blocked due to oxidation; should this problem occur the alarm sounds (7) (slow wash tank
load - chap. 11.2). Call a Service Technician to unblock (also check the water pressure and
quantity).
7.11 Energy-Saving function
If this function is enabled, it reduces boiler temperature when the machine is standing-by
for a subsequent cycle.This saves energy.
7.12 Thermostop function
Ifenabled, thisfunction waitsfor theboiler temperatureto be reachedat theend ofthe wash
cycle, prolonging washing before the rinse cycle begins.
7.13 Conditions that inhibiy the washing cycle
The washing cycle is annulled and brought to stop position under the following conditions:
• if fault is detected
• if the (B - ON/OFF) button is held for more than 2 seconds.
pict. 9
• Replace with the strainer and two lateral compensation chutes.
Once this operation is complete, simply select cycle 1 granule mode and with the door
shut press (START). One the cycle is nished, the granules shall be found in the collection
strainer. To clean, simply place the strainer in a sink and wash from above.
On this occasion, check granule consistency and quantity (see photo 1).
If they are too small and spherical, replace; if they are too few, add to level.
Excessive amount or lack of granule can result in unsatisfactory results, when using the
granule mode.
7.8 Chamber cleaning
Once the cleaning stage is nished, replace the overow, chutes and lters and proceed
with new lling (see 7.2).
Periodically remove the wash arms and clean under running water.
Periodically remove the rinse arms and clean the nozzles.
Reassemble the nozzles as originally assembled.

10. ECOLOGICAL ASPECTS
10.1 Recommendations for optimal use of energy, water and additives
Use the machine fully loaded when possible.
This shall prevent detergent, rinse aid, water and energy consumption waste.
Detergent and rinse-aids
Use detergents and rinse-aid chemicals with high biodegradability, to best respect the en-
vironment. Verify proper dosage in relation to water hardness at least once a year. Excess
product pollutes rivers and seas while an insuf cient dose results in unsatisfactory dish
washing and/or hygiene.
Boiler and Tank temperatures
The boiler and tank temperatures are set by the manufacturer in order to obtain the best
washingresultswithdetergentsonthemarket.Thetemperaturescanberesetbytheinstaller
in relation to your detergent.
Pre-washing
Carefully pre-wash with a moderate amount of water at room temperature to facilitate the
removal of animal fats.
To remove encrusted materials warm water soaking is recommended.
Note:
Wash objects as soon as possible to avoid deposits from drying and compromise effective
washing.
For effective washing routine dishwasher cleaning and maintenance is advised (see chap.
8).
The disregard of the points listed above and of any the information contained in this
manual can cause energy, water and detergent waste with a subsequent increase in
cost and/or performance reduction.
