5. INSTALLATION
IMPORTANT: The machine must be positioned against the wall
(minimum distance 10 cm) and must be installed by a technician
authorized by the manufacturer.
The technician who installs the machine is responsible for the
appliance operating correctly after it has been installed. He is also
obliged to provide the user with all the information required to use
the machine in the correct way.
All adjustments, servicing and so forth, must be carried out with the
appliance disconnected from the electricity main.
The scratch-proof film must be removed from the external steel
surfaces when the appliance is installed.
IT IS STRICTLY FORBIDDEN FOR UNAUTHORIZED PERSONS TO
USE THE MACHINE.
5.1. POSITIONING
The side panels of the machine must adhere to the adjacent furniture and care must
be taken to leave space at the rear: it is therefore advisable for the wall at the back to
be made of brickwork or some other impermeable material.
The machine has pipes to supply and drain off the water. These can be positioned
towards the right or left, depending on the installation requirements.
The machine can also be installed under a work top: this operation must be carried out
by specialized personnel.
5.2. LEVELLING
Once the machine has been set in position, it must be levelled until horizontal (2
degrees tolerance allowed) by either screwing in the feet or unscrewing them.
Correct levelling will ensure that the machine operates in the right way.
5.3. CONNECTION TO WATER MAINS
Prevent the risk of clogging or damage to the appliance: if the water pipe is new or has
remained unused for a long period of time, make sure that the water is limpid and free
from impurities before connecting the machine to the water main.
The pipe is pre-engineered for connection to a cock with 3/4’’ gas threaded union on
both ends.
Insert the supplied filters "A" before connecting the other ends of the pipes to their
respective cocks.

WD1050 12/04/2010 Pag. 10
It is advisable to allow the water to run in order to drain off any rusty deposits or
sludge if connections are made with new pipes.
In case of blood-stained instruments make sure that the machine is not supplied with
water at temperature higher than 40°C.
WARNING
Make sure that the inlet pressure of the mains water is within the
operating limits: min. 2 bar - max 5 bar.
The water shutoff valves must be accessible
Always shut off the water supply cocks when the machine is not being used
CAUTION
Chemical characteristics of mains water that are not compatible
with a good washing process.
If the water contains more than 0.5 ppm of iron Fe
2+
/Fe
3+
and/or the
hardness of the water is more than 42°F (French degrees), it must be
pre-treated by installing a deferrization and/or softening system
upstream.

WD1050 12/04/2010 Pag. 11
5.4. WATER SUPPLY
The machine is supplied with two water supply pipes that join to a non-return device
inside the machine.
The pipes are designed for connection to cocks with 3/4” gas threaded bushings.
The following pipes (see the picture below) must be connected to water mains:
 cold water pipe;
 pressurized demineralized water pipe (min. 2 bar - max. 5 bar) – if present.
If demineralized water isn't available: don't connect the demi pipe
to the cold or hot water, leave it disconnected and see the
instructions (paragraph "DEMI WATER SETTINGS" 6.11) in order to
set correctly the demi water parameter.
fig. 3 – Back view of the machine

WD1050 12/04/2010 Pag. 12
5.5. NON PRESSURIZED DEMINERALIZED WATER CONNECTION
The connection to a non-pressurized demineralized water supply (e.g. gravity tank) is
possible only by installing the special demineralized water pump, called "PAD5".
The PAD, optional booster pump, ensures the correct inlet water supply pressure
within the pre-set filling time.
This accessory can be fitted on any machine and must be mounted on the back of the
machine.
If the PAD pump is used, the water supply pressure must be less
than 1 bar.
We advise having the pump installed by a specialized technician, who should follow
the instructions provided.
The manufacturer will accept no responsibility for any possible damage caused
by an incorrect installation performed by an unauthorized technician.
WARNING
Make sure that the demineralized water pressure is less than or
equal to 1bar. The manufacturer declines every responsibility for
higher pressures.

WD1050 12/04/2010 Pag. 13
5.6. WATER DRAIN CONNECTION
This machine has just one outlet hose.
The internal diameter of the hose is ½” so it can be connected to any standard ½”
hose adapter.
General rules for installing outlet
The washing water outlet hose must be placed with its curved section hooked onto the
edge of a sink or waste pipe. A drain pipe with siphon should be used.
The following precautions should be observed during installation:
•As the water drain temperature may reach about 93°C the end of the outlet hose
must be connected firmly to the drain by using clamps.
•The outlet hose must not have any tight bends liable to obstruct the flow;
•The end of the outlet hose must not be placed either more than 80cm or less than
65 cm above the surface on which the machine is installed;
•The end of the hose must under no circumstances be immersed in water;
•The internal diameter of the waste pipe must be at least Ø 40 mm;
•We recommend installing a waste pipe of diameter 50 mm;
•Don't use waste pipe extensions.
fig. 4 – 65 cm < A < 80 cm
WARNING
The drain connection must comply with international standards.
Our company will accept no liability for pollution caused by the
machine. .

WD1050 12/04/2010 Pag. 14
5.7. ELECTRICAL CONNECTION
The machine is designed for connection to an electricity main with the following
voltage rating:
•WD1050 ~ 230V 3 / N / PE 50Hz.
There is also a single-phase and 230V three-phase "without neutral", with the following
electrical characteristics:
•WD1050-1 ~ 230V 1 / N / PE 50Hz.
•WD1050-3 ~ 230V 3 / PE 50Hz.
WARNING
The machine is equipped with a power cable for permanent connection to the

6.1. WASHING PROGRAMME SETTINGS
The instrument washer has a practical display that provides all the information the
user needs to know about the functions programmed.
Consult the following table to select the required programme. It gives the washing
cycle most able to suit the nature of the instruments you need to wash and the degree
of dirt involved.
Once you have found the most suitable washing programme in the table, turn the
PROGRAMME SELECTOR knob and select the desired programme by setting it to the
relative reference number.
The following is an indicative list of the type of washing cycles to which the available
programmes refer:
1. Quick washing programme using cold water.
2. Washing programme at 60°C suitable for plastic w are.
3. Washing programme at 75°C suitable for standard glassware.
4. Washing + disinfection at 90°C for 1’ (A 0 =600).
5. Washing + disinfection at 90°C for 5’ (A 0 =3.000).
6. Washing + disinfection at 93°C for 5’ (A 0 =6.000).
7. Washing + disinfection at 93°C for10’ (A 0 =12.000).
8. Service programme: to test the detergent and neutralizer dispensers and rinse the
washing chamber.
6.2. THERMAL DISINFECTION IN ACCORDANCE WITH THE PARAMETER "A0"
We introduce the "A
0
concept" to explain the time/temperature relationship used to
draw up the programmes.
According to EN ISO 15883 and the recommendations of the Robert Koch Institute
(European authority on the subject), an A
0
of 600 is considered as the minimum
standard for non-critical medical devices, i.e. for those that only come into contact with
uninjured skin. A further condition required is that microbic contamination must only be
slight and there must be no heat-resistant pathogens present.
An A
0
value of 600 can be obtained by maintaining a temperature of 80°C for 10
minutes or 90°C for 1 minute or again, 70°C for 100 minutes.
If the medical devices are contaminated with heat-resistant viruses, such as those of
hepatitis B, the value of A
0
must be at least 3000. This can be obtained by
maintaining a temperature of 90°C for 5 minutes.
An A
0
value of 3000 is considered the minimum value to apply to all medical devices
considered to be critical.
Programmes that include thermal disinfection have therefore been designed to offer
the following A
0
values:
