CWG410

Water supply and drain connection

The water pipelines and electricity supply cable lead out of the bottom right­hand corner of the appliance. Connect the water intake hose to a connector
with ¾” gas threaded fitting, fitting the filter A provided (in models with
aquastop, the filter and ring-nut form a single unit).
The connection to the water mains must only be made with new hoses; the
use of old or worn hoses is not permitted.

Caution: the indoor system and premises in which equipment for institutions is installed
must comply with the relevant regulations.

The manufacturer declines all liability for direct or indirect injury or damage deriving from failure
to comply with these regulations.
Before installation, check that there are no objects or materials in the vicinity which may be
damaged by steam or splashes of washing solution, or that any such items are suitably protected.
Place the dishwasher in the chosen point and remove the protective film.
Level the dishwasher (with the aid of a spirit level) on its adjustable feet to ensure that it is stable;
all other mounting solutions must be approved by the manufacturer.

POSITIONING:

4 INSTRUCTIONS FOR TECHNICAL STAFF

4.1 Plumbing hookup

The dynamic water supply pressure must be between 2 and 6 bar; if it is higher a pressure reducer
must be installed. If the pressure is less than 2.5 bar it might be necessary to fit a special pump on
the appliance to ensure optimal performance. Contact the After-Sales Service.
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 dishwasher.

The stated cycle duration applies to appliances supplied with hot water >50°C<60°C
If the dishwasher is supplied with cold water, the cycle duration might increase depending on the

intake water temperature.

7

CWG410

Caution: make sure that the intake and drain hoses are not bent, constricted or crushed
after installation.

The dishwasher and any additional equipment must be connected to the electrical
system by authorised, skilled staff, in accordance with the relevant regulations; 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 dishwasher 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 dishwasher, be easily accessible after
installation, and provide complete disconnection from the electrical mains in
overvoltage class III conditions.

Warning !!!
The dishwasher 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 right-hand corner of the appliance.
The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the live
wires (L1, L2, L3) are black, grey and brown.
In the event of single-phase connection (230V-1N~), the connection to the electrical
mains must be made using a cable with plug 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.

Drainage:

The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or
wall.
Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL

DATA)

When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is
reduced to 600 mm.

4.2 Electrical connection

8

CWG410

Before inserting the hoses into the containers, fit the weights (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 detergent dispenser is not factory-fitted, it can be retrofitted after
ordering the relative kit.

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 dishwasher is equipped with an automatic water softener which removes
the substances that cause hardness from the water with the aid of regenerating
salt.

The first time the dishwasher 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 detergent must not get into the salt tank, as this
would impair operation of the regeneration system.
In this case warranty cover will be forfeited.

5 FIRST START-UP

First start-up

The electrical protection system must undergo 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 operating instructions.

Preparing for use (important)

The rinse aid dispenser is fitted on all models, the detergent dispenser only on some.
If both dispensers are present put the external detergent and rinse aid containers in place and
insert the respective intake hoses on the rear of the appliance into them.
Red hose: detergent
blue hose: rinse aid

NOTA:

It takes about 10-15 wash cycles before they arrive in detergent and rinse tank and boiler.

As an alternative an external dispenser can be fitted, making the electrical connection by means of
an H05 RN-F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL
DATA diagram and connected as shown in the wiring diagram supplied with the dishwasher.
The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.
Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above.

5.1 Using the water softener (on models with this feature only)

9

CWG410

IMPORTANT:

Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out
the peristaltic pumps by placing the external intake pipes in water for a few cycles.

Always use only products specifically recommended for use in a dishwasher.

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 diaphragm rinse aid pump
should be checked.

To reuse the appliance, repeat procedure 7.3

Caution: use only salt of the specific type, do not use cooking salt.

Salt must be added when the LED underneath the symbol shown in the box on the left
lights up.
Top up with salt when there is no water in the tank to prevent washing water from getting
into the water softener device.
The salt tank has a capacity of about 1 kg of coarse-grained salt .
The salt tank is in the bottom of the appliance's tank. After removing the basket, undo the
cap and pour the salt in using the funnel supplied. Remove any salt residues around the
opening before screwing the cap back on.

After a total pump-out the filters should be cleaned as described in the relevant point.

Resin regeneration (for models with water softener)

Once the set number of wash cycles is reached (see point 6.9 of “Technical Manual”) the LED above the

key flashes. Therefore, during the working day resin regeneration is RECOMMENDED, following the

procedure described below.

Filling up with regenerating salt

(for models with water softener)

20

CWG410

Remove the filters (simply lift them out as shown here), taking care
that no large residues fall into the sump underneath. Clean them to
remove residues and rinse with plenty of water, then put them
correctly back in place; do not use sharp or pointed tools.
Clean away any limescale deposits to prevent excessive build-ups;

The dishwasher has IPX4 protection but pointing water jets straight at it for cleaning is
forbidden

9 MAINTENANCE AND CLEANING

Although no particular scheduled maintenance is required, users are advised to have the dishwasher
checked by a specialist technician twice a year.
N.B. the manufacturer accepts no liability for wilful damage or damage deriving from carelessness,

neglect, failure to comply with instructions, regulations and standards or incorrect connections, which
lead to forfeiture of warranty cover.

If possible, leave the door ajar when not in use;
Clean surfaces thoroughly and often with a damp cloth; use neutral, non-abrasive detergents which do

not use chlorine compounds, which corrode and damage stainless steel.

Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of
the dishwasher,
to ensure that fumes or drops cannot damage the steel surfaces.

9.1 Daily cleaning of filters

Cleaning the filter at the end of each working day

9.2 Routine inspection of the spray arms (once a week)

Remove the washing and rinsing (top and bottom) spray arms by unscrewing the central screw; remove
the rinsing spray arms 3 and remove the screws 2 as shown. Do not unscrew the nozzles. Clean the
holes and nozzles under a jet of clean running water; do not use tools which might cause damage.
Reassemble the spray arms with care.

Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.

9.3 Lengthy periods out of use

If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid
dispenser devices must be emptied to prevent crystallisation and damage to the pumps: remove the

intake hoses from the detergent and rinse aid containers and place them in a container of clean water,
then perform a few wash cycles followed by a complete pump-out.

Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior
is completely dry. The detergent and rinse aid intake hoses must be put back into the containers when
the dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue
hose = rinse aid).
