3. GENERAL RECOMMENDATIONS

Never use alcohol or solvents such as turpentine in the appliance as they could cause

explosions. Do not place materials dirtied with ash, wax or paint in the appliance.

• Do not rest or sit on the open door of the instrument washer as this could cause the appliance to tip over

and endanger persons.

• Never ever touch the heating elements in the tub just after a washing program has terminated.

•

The heating elements could become slightly discoloured as the instrument washer is used. This is normal as

it depends on the operating mode and will in no way impair the way the appliance operates.

•

Discarded appliances must be rendered unusable. Cut off the power flex after having detached the terminals

from the electric panel. After this, the appliance must be consigned to a differentiated waste collection

center.

•

If the appliance functions in a faulty way, disconnect it from the electricity main and shut off the water

cocks. After having done this, call the nearest authorized Assistance Center.

The machine must only be used by specifically trained persons. It is Smeg’s task to train the

designated users when the appliance is installed.

. insert the screwdriver into the hole;

. push on the screwdriver delicately without forcing until you hear the closing mechanism release.

The door may be opened during the cycle only if the temperature inside the washing chamber
has not exceeded 40°C. Use the keyboard to open the door.

Depending on the settings chosen for the system, a password must be entered to open the door
during a washing cycle. However, it is always advisable to wait until the cycle terminates before
opening the door.

It is dangerous to open the door when the temperature inside the washing chamber exceeds
50°C!
Smeg declines all liability for damage to persons or property caused by forcing the door open

during a thermal disinfection cycle.

5.8

BUILT-IN SOFTENER

The machine has a softener for the washing water.

The amount of lime in the water (denoting its hardness) is responsible for the whitish stains on the dry
instruments, which tend to become opaque after a certain period of time. The instrument washer is equipped
with an automatic decalcifier which removes the hardening substances from the water by means of specific
regenerating salt.

•

Before the instrument washer is used for the first time, pour 1 kg of salt into the reservoir along with a
little water to fill. Make sure that the plug is firmly closed each time the reservoir is filled. The water and
detergent mixture must not penetrate into the salt reservoir as this would prevent the regeneration
system from operating correctly. Moreover, the washing tub and the instruments inside it would be
damaged if salt were to spill out. If this were to occur, the warranty would become void.

Only use regenerating salt for domestic dishwashers. Do not use normal kitchen salt.

• Edible salt must not be used as it contains insoluble substances that could damage the water softener

over a period of time.

The ionic exchange resins of the water softener are regenerated by sodium chloride, i.e. common salt (NaCl).
The only routine maintenance required is to add coarse salt to the reservoir when the appliance is installed and
after this, whenever the following alarm message appears on the display:

Lack of salt

! ! ! ALARM: W075

Ignore ? ?

<N>

+

II



When this message appears on the display, it can be ignored by pressing key

and then key

However, it is inadvisable to ignore this message since a softener that fails to function correctly will impair the
quality of the washing result and could even damage the processed instruments over time.

5.8.1 How to add salt

If the water used is of medium hardness, fresh salt must be added after every 20 washing cycles approximately.
The reservoir of the decalcifier contains about 1 kg of coarse salt. The reservoir is situated at the bottom of the
instrument washer (see fig. 3.2.2.1). Remove the lower basket, unscrew the reservoir’s plug by turning it in the
anti-clockwise direction and then pour salt inside using the funnel supplied with the appliance.

Do not use compressed salt tablets or fine salt as these can clog the regeneration valve.
Close the reservoir by turning the plug clockwise. Make sure that the plug is not blocked by salt residues. The
plug must be screwed fully into place without forcing.

Versione 09/11/2009

Manuale GW3060- User

Before proceeding with a new washing cycle, it is advisable to run the “Prewash” program 1 to eliminate any salt
residues that may have remained in the tub along with the excess initial salt.

Fig. 3.2.2.1

After the salt has been added, remember that the resins will only regenerate automatically for the first time after
several work cycles, i.e. when the softener’s operating capacity has terminated.
Since the softener’s new resins are not always regenerated to the full extent, the glassware may appear opaque
during the first 2/3 cycles owing to lime residues.
To prevent this from happening, the softener’s resins can be subjected to a Forced Regeneration cycle. Consult
the next chapter: “FORCED REGENERATION OF THE SOFTENER”.

5.8.2 Use of the appliance with softened mains water

If already softened hot or cold mains water is available with a hardness value of less than 15°F (expressed in

French degrees) or 8°D (expressed in German degrees), the regeneration cycle of the built-in softener must be

inhibited and salt must not be added to the softener.

Consult chapter 6.1 of the TECHNICAL MANUAL and set Softened Water to <Y> to inhibit the Water
Softener.

It is very important to make the adjustments described in the above-mentioned chapters in the correct way as the
passage of softened water through a softener designed to treat hard water will entrain chlorides and sodium
carbonates along with the washing water. These inorganic salts can leave whitish stains on the washed glassware
and, in the case of surgical instruments, may turn the metal yellow or reddish brown.
These whitish deposits on the glassware can be removed by means of a special acid washing cycle using 200/250
ml of neutralizer.
If the colouring on the surgical instruments is persistent, it may be necessary to treat them with an appropriate
stain remover.

HOW TO REGULATE THE WASHING PRESSURE IN THE SPRAYING ARMS

The pressure of the washing water in the top and bottom spraying arms can be regulated by means of the
adjuster under the spraying arm itself. Turn the adjuster lever fully towards the left (normal position) to obtain
the maximum pressure in the top spraying arm or in the injection system.
Turn the lever towards the right (towards the bottom of the tub) to obtain the maximum pressure in the bottom
spraying arm as the top one will be throttled.

1 Maximum flow at top level
2 Balanced flow
3 Maximum flow from bottom arm

5.10 HOW TO FILL THE WASHING TROLLEYS

The machine is supplied without trolleys. The Customer chooses the trolleys he needs from a vast range of
available solutions.
These trolleys are simply placed on the door and allowed to slide inside. Connection to the hydraulic circuit is
automatic. It may be necessary to initially adjust the upper funnel at the water inlet.

A loaded trolley can weigh as much as 20 kg: take care when handling it. Persons with problems
affecting their backs or articulations should not load or unload the trolleys.
Smeg declines all liability for problems concerning the health of persons caused by lengthy use

of the machine.

Take great care when positioning the instruments in the baskets/trolleys: a good position,
where all the surfaces are exposed to the washing action certainly contributes towards the result
of the washing and disinfecting cycle.

5.11 DETERGENT DISPENSING SYSTEM

The machine is equipped with peristaltic pumps that dispense liquid detergents.
Each tube is marked by a tag that indicates the number of the pump and the relative additive it can dispense:

take care not to invert the tubes!

The level of the liquid is monitored by means of level sensor.

Fig. 5.11.1

Up to four 4 cans can be housed in the side cabinet on two can baskets that run on pull-out guides for easier
positioning and replacement.

The plug must be removed from each can and the suction
device with its plug inserted instead.

If detergent spills out of the container it
must be dried immediately.

6. WASHING PROGRAMS - DESCRIPTION

SMEG programs are installed in program positions 1 to 20. These programs have been researched and
formulated so as to guarantee the best possible washing and disinfecting results. However, they can be changed
in relation to the quantity of detergent.

The remaining 10 positions from 21 to 30 are empty and can be used by the customer to create his own
programs. These new programs can either be created in the manual mode by means of the keyboard, or by using
Smeg’s application software WDTRACE (which can be purchased as an optional).

It is always possible to reinstall the original programs by loading them (consult the relative section).

6.1

WASHING AND DISINFECTING PROGRAMS

The functions accomplished by the 20 default programs are described in chapter 6.3 on pages 33,34 and 35.

Only peristaltic pumps 1 and 2 are activated in the standard programs. To activate the other pumps, access the
programming menu and activate them in the required phase.

A drying phase for the material can be added to the washing program (see Drying Programs section).
NOT APPLICABLE FOR THE GW3060 MODELS.

Warning

To prevent possible contamination amongst the various cycles due to water residues that may have remained
after a program, it is advisable to run program N° 1 (tub prewash) at the beginning of a work day as a preventive
safety measure.

A washing program generally comprises phases of different types:

• Prewash with mains or demineralized water

dilutes or softens the pollutants on the instruments; Use cold water without additives to eliminate coarse
dirt and foam substances.

• Hot alkaline wash

effective action that detaches the pollutants from the walls and solubilizes them; this phase is usually
performed at temperatures between 40°C and 65°C for a few minutes. Alkaline or neutral detergents are
used.

• Neutralizing in an acid environment

action that eliminates alkaline residues
solubilization of the calcium carbonate precipitates from the surfaces of the instruments
prevents the surfaces from becoming opaque

• Rinsing with mains water

dilution of the previously used chemical additives
every rinse dilutes the initial concentration of the pollutant by about 99%

•

Rinsing in demineralized water

dilutes the inorganic salts and any organic fractions in the mains water

•

Thermal disinfection

Thermal disinfection is a hot alkaline washing phase where the washing temperature exceeds 70°C and is
maintained for a period of time that depends on the required thermal disinfection action.
Consult the next section for details about the thermal disinfection process.

•

Drying phase

Final process phase that must guarantee sufficient drying

EFFICACY OF THE WASHING ACTION AND DETERGENTS

To ensure that the materials processed by the instrument washer are completely washed and disinfected, the
washing phase/s must be as efficacious as possible.

The following factors contribute towards improving the efficacy of the washing process:
. arrangement of the instruments in the washing trolley in the best possible way;
. quality and quantity of the water;
. pressure of the water in the washing ducts;
. temperature at which washing occurs;
. detergents used.

6.2.1

Arrangement of the instruments in the washing trolley

Take the following precautions:
. do not fill the trolleys with too much material and/or too many glassware at the same time
. position the glassware so that they are unable to obstruct the spraying arms.

6.2.2

Quality and quantity of water

It is essential for the water to be of a good quality. Have the water in the water supply system periodically
checked. Connect the demineralized water supply when possible (conductivity < 8-10 µS).
It may be advisable to increase the amount of water used for each phase (by means of the relative menu),
depending on the washing trolley and program selected; this parameter may not be changed for Smeg’s
programs.

6.2.3

Water pressure

By operating correctly, the washing pump ensures that the pressure in the machine’s hydraulic circuit is correct.
An alarm message will appear on the display if the pressure is incorrect.

6.2.4

Washing temperature

The optimum temperature at which washing takes place depends on the type of detergent used and the
instruments to process. However, washing temperatures must usually exceed 50°C, otherwise the chemicals will
be inefficacious.

6.2.5

Detergents used

The detergents used represent the most important factor for obtaining an optimum washing result. Smeg
guarantees that optimum washing results are obtained so long as the customer uses the products tested along
with the appliance.

Smeg has prepared two groups of programs that differ as to the type of detergents used: both groups provide
optimum washing and disinfecting results, depending on the case in question.

Here are the products for which Smeg guarantees the envisaged washing results:

alkaline detergents: Smeg’s DETERLIQUID D and D2

acid neutralizers: Smeg’s ACIDGLASS P and P2

soda caustic 33%: to be supplied by the end-user

anti-foam agent: Smeg’s F1-S or F2-S

Handle cans containing detergents with care: always wear protective gloves when transferring
liquids, topping up and inserting the suction devices.
Wash the affected area immediately with water if detergent substances splash on to the skin.

Consult the next section for further details.

6.3

THE THERMAL DISINFECTION PROCESS

Over the last few years, many efforts have been made to improve the decontamination of instruments and
glassware: specific standards for both the process and techniques used have been issued and have defined the
state-of-the-art. All this has provided the end-user with quality and safety advantages.

We would now like to go on to describe the A0 concept (see Tab. 1) defined by EN ISO 15883, which explains
the meaning of the temperature and time values indicated in the thermal disinfection programs.

Value

A

indicates the degree of thermal disinfection of the corresponding program: thermal disinfection is all

0

the more efficacious and suitable for particular instruments the higher its value is.
Research has been conducted according to which, by conducting washing cycles that comply with these 2
parameters, i.e. temperature @93°C and holding time @10 min., one obtains a high degree of microbiological
disinfection in the treated materials, such as to inactivate the majority of the bacteria (with the exception of
spores) and heat-resistant viruses such as the HIB viruses of hepatitis A and B as well as the HIV virus
responsible for AIDS.
Thermal disinfection processes that provide a good degree of disinfection can also be carried out at lower
temperatures and with shorter holding times. The temperature/holding time combination depends on which
type of disinfection is required.
A stands for the equivalent time in seconds required to produce a given disinfection effect at a temperature of
80°C (taken as a reference). If D is the time required to reduce the bio burden on the instrument treated by a
factor 10 (thus with a 90% “lethality” degree) at a particular temperature, value z can be expressed as the
temperature increase (in K degrees) required to reduce D (in boldface) by a factor 10. In view of this, A0 stands
for the value of A when the temperature is 80°C and value z equals 10.
In short, the value of A0 expresses the degree of “lethality” in seconds at a temperature of 80°C, released by the
thermal disinfection process to the device under treatment, with reference to micro-organisms that possess a z
value of 10 (a characteristic valid for many micro-organisms). The A0 value that must be obtained depends on
both the type and number of micro-organisms on the contaminated medical device and on its successive use.
According to EN ISO 15883 and the recommendations of the Robert Kock Institute (European authority on the
subject), an A0 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 A0 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 (lower
temperature are not recommended).
If instruments are contaminated with heat-resistant viruses, such as those of hepatitis B, the value of A0 must
be at least 3000. This can be obtained by maintaining a temperature of 90°C for 5 minutes.
An A0 value of 3000 is considered the minimum value to apply to all medical devices considered to be critical.
Programs that include thermal disinfection have therefore been designed to offer the following A0 values:

NOTE ** WASHING TIMES:

The times given in the table are indicative and refer to the following operating conditions:
400V – 7.0 kW three phase electric power supply
Cold water supplied at 20°C – 3 bar
Program 1 is only a simple pre-wash lasting for 6 minutes. They are useful if the appliance is partially filled with materials stained with blood and a true washing
program need not be used at that time. This prevents the blood from coagulating, thus making the instruments easier to clean and preventing longer washing programs
from being used.

7. ALARM MESSAGES

Different messages appear on the display if the appliance operates in a faulty way or water and/or detergent are
lacking. There are two different situations, depending on how serious the fault is:
. warning messages;
. true alarm signals.
In he first case, there will be a message allowing the user to ignore the warning and proceed with the selected cycle
while in the second case, the user must press the Reset button and comply with the relative procedure in order to
overcome the situation.

By and large, an alarm indicates that the machine is operating in a faulty way and needs to be repaired by a technician.
Sometimes, however, the alarm may be caused by a temporary situation. Before calling the authorized Technical
Assistance service you are therefore advised to make a Reset and repeat the cycle a second time. Call the authorized
Technician if the alarm persists.

The possible alarm messages are indicated below.

To release the machine when one of these messages appears, depress the RESET key
for a couple of seconds in order to activate the RESET cycle.
If a cycle has been stopped during a high temperature phase, remember that the temperature must

drop below 45°C before the door can be opened.

8. CLEANING AND SERVICING

Before proceeding with any servicing work, disconnect the electrical and hydraulic connections, i.e. make
sure that the water cocks are shut and that the switches of both the machine and electric panel are in the
OFF positions.

8.1

ROUTINE INSPECTIONS

The following inspections must be carried out periodically to make sure that the machine remains in a perfect
condition.

Each day
Power the appliance
Check the detergent levels
Clean the spraying arms, the filters and the washing chamber
Visually check the washing indicators
Check the temperature parameters with a thermologger
Thermal disinfection of the empty washing chamber
Visual inspection of the washing results after each cycle

Each week
Check the suction action of the dispensers (adjust the positions of the tubes if necessary)

Every six months
Servicing by an authorized technician

Each year
Validation in accordance with EN ISO 15883
Biological controls

8.2

HOW TO CLEAN THE SPRAYING ARMS

The spraying arms can be easily removed in order to clean the nozzles and prevent clogging. Periodically remove the
spraying arms after having unscrewed the knurled nuts, wash them carefully, fit them back in their housings and fully
tighten the knurled nuts. It is particularly important to make sure that the small circular hole at the end of the spraying
arm is perfectly clean.

8.3

HOW TO CLEAN THE FILTERS

The filtering unit comprises a circular filter with a filter cone, a micro filter and a coarse filter. To ensure that the
machine functions in an efficient way, it is extremely important to keep the filters clean. Inspect the filters often (e.g.
if glassware with paper labels is washed, the filters must be checked after each cycle) and remove any deposits that
could impair the way the appliance operates.

Coarse filter

Remove the coarse filter by pressing on the lobes and pulling upwards (fig. 19). Clean the filter and set it back in
position.

Micro filter

This is positioned under the coarse filter (fig. 20). It is advisable to check and clean it when the coarse filter is
inspected.
Use a brush and hot water to clean this filter perfectly.

Circular filter

Proceed as described below to disassemble this filter:

• hold the coarse filter by its lobes and turn it in the anti-clockwise direction (fig. 21).

Versione 09/11/2009

41

Manual GW3060 - User

• lift the entire assembly (i.e. filter, filter cone, coarse filter and microfilter) without pressing the lobes (fig. 22).

When this filter is cleaned, it is also advisable to clean the others.

EXTERNAL CLEANING

The external parts of the appliance must be periodically cleaned.
The front panel can be cleaned with a soft cloth, using water and a delicate detergent (such as the ones used for
crockery) in diluted form.
Do not use alcohol, solvents or the ammonia-based products used for cleaning windows.

The steel surfaces can be cleaned with alcohol and various detergents.
If there are heavy incrustations, use a fine abrasive paste with an electric polisher and soft pads.
After this, normal detergent products can be used.

In places where strong acids are used (hydrochloric/sulphuric/nitric), it is advisable to clean the machine with a soft
cloth soaked in paraffin oil. This film will protect the steel from acid vapour aggression.

8.8

HOW TO SERVICE THE APPLIANCE

The user must call SMEG’s authorized technicians at least once every 12 months (once every 6 months is better) for
preventive maintenance purposes and for the visual inspection required for safety reasons.
The technician must:

• replace all the tubes and cans containing liquids if necessary, since faults could arise if these parts are defective

• check the safety thermostats, the ground terminals and protection conductors, replacing any defective or worn

components if necessary.

All the replaced components must be supplied by SMEG or by one of SMEG’s authorized centres.

Make sure that there is a clear area of at least 1m2 in front of the machine before proceeding with any
maintenance/repair work.
