REV_2.00_COD.500159_A4 PAG. 7
2.3 Safety recommendations
•If the new machine appears to be damaged, contact the retailer before starting it.
•Any modification of electrical and hydraulic systems necessary to install the machine must be carried out by
qualified, authorised persons only.
•This machine must be operated by trained persons only;
•The machine must be used for treatment and thermo disinfection of instruments for orthodontic and medical
use and for laboratory glasses.
•Any use other than that for which the machine was intended is forbidden.
•The user is forbidden to carry out any work or repairs on the machine.
•Technical Assistance for this washer disinfector should be carried out by qualified and authorised operators
only.
•The equipment should be installed by authorised persons only.
•Do not install the equipment in rooms where there is the risk of explosion.
•Do not expose the equipment to intense cold.
•The electrical safety of this washer disinfector is only guaranteed if it is connected to an efficient earth system.
•Take great care when handling detergents and additives: avoid contact, wear gloves and act in compliance with
the safety recommendations indicated by the manufacturer of the chemical products.
•Do not inhale the fumes produced by chemical products.
WARNING:
The chemical products are an irritant for the eyes, in case of contact rinse thoroughly with plenty of
water and consult a doctor.
If these products come into contact with the skin, rinse with plenty of water.
•The water in the tank is not drinking water.
•Do not lean on the door and do not use it as a step.
•The machine reaches a temperature of 93°C during the work cycle: take great care to avoid burns.

REV_2.00_COD.500159_A4 PAG. 8
2.4 Recommendations to ensure high quality
performance
•The user must oversee the machine during the cycle.
•The injection tube for washing water must always be connected with the appropriated basket.
•When the machine is running do not interrupt the cycle since this jeopardises disinfection.
•Check periodically using chemical indicators to ensure correct disinfection.
•Use recommended detergents and chemical additives only.
The use of other products may damage the machine.
•During the manipulation of treated objects, it is required the use of appropriated DPI to prevent contact
with infected material and the risk of contamination.
•Recommending chemical additives does not make the manufacturer responsible for any damage to the
materials and objects treated.
•Do not introduce dirty instruments of substances that must not be discharged in sewage system (in
accordance with current legislation) but must be disposed in specific way.
•Follow the manufacturer's indications when using chemical products and use them for the foreseen
use only.
•The machine was designed for use with water and chemical additives.
Do not use organic or other types of solvent as this may result in the risk of explosion or the rapid
deterioration of certain machine parts.
•Residues of solvents or acids, particularly “hydrochloric acid”, can damage steel.
Contact should be avoided.
•Use original accessories only.
•Do never use soap powder.
•Do never use foaming detergent.
•Accessories which are not approved by the manufacturer may compromise the results achieved as well
as user safety.
•Do never use chemical products based on chlorides (bleaches, sodium hypochlorite, hydrochloric acid
and so on).
These kinds of chemical detergents irreparably damage the machine and jeopardise the integrity of
materials and objects treated.
The taps of the water feeding must be always turned off, as the safety and diagnosis system will be deactivated,
in the following situations:
•if the machine is left unused
•if the machine is disconnected from the electrical connection
The manufacturer declines all responsibility for personal injury or material damage resulting from
the non-observance of the above rules.
The non-observance of these rules produces the total and prompt cancellation of the guarantee.

REV_2.00_COD.500159_A4 PAG. 9
2.5 Residual risks
The appliance includes a series of fixed guards to prevent access to hazardous internal parts or zones.
It is however considered that the WASHER DISINFECTOR includes some residual risks.
Hereunder for each phase or significant work intervention are useful measures to be taken:
PHASE TROLLEY LOADING
RISK Contusions and cuts to the upper limbs, due to accidental contact with due to falling or
striking against tools, objects and instruments, mainly while loading and handling the
basket.
MEASURE Assign staff that is instructed and equipped with work equipment (e.g. trolley with protections, transport carts) and appropriate clothing and individual protection gear (e.g.
shirts and protective gloves).
PHASE OBTAINING DETERGENTS/CHEMICAL ADDITIVES
RISK Contact with body parts with chemical washing products.
MEASURE
Assign staff that is instructed and equipped with appropriate clothing and individual
protection gear.
Wear clothing, gloves and goggles and act in compliance with the safety
recommendations indicated by the manufacturer of the chemical products.
FIRST AID MEASURE
•Immediately take off/remove clothing which has been contaminated or soaked by the
product.
•If the substances come into contact with the skin, wash off affected skin areas
immediately and rinse with water.
RISK Inhalation of vapours of chemical wash products.
MEASURE Assign staff that is instructed and equipped with appropriate clothing and individual
protection gear.
Comply with the safety instructions provided by the manufacturer of the chemical products
and if there are none, wear a mask for the protection of the respiratory airways.
RISK Accidental release of chemical wash product
MEASURE Do not flush concentrate into drains, surface or ground waters.
Collect spillage with adsorbent material (e.g. sand, earth, vermiculite, diatomaceous
earth).
Flush away minor amounts with plenty of water.
IN CASE OF CONTACT WITH BODY OR RELEASE OF CHEMICAL PRODUCT LOOK
ALWAYS AT THE SAFETY MEASURES INDICATED IN THE CHEMICAL TECHNICAL
DATASHEET.
PHASE MAINTENANCE OF INTERNAL EQUIPMENT
RISK Burns of body parts by hot parts of the appliance.
MEASURE Allow maintenance to be performed only by trained personnel, equipped with appropriate clothing and individual protection gear.
Wear suitable clothing and protective gloves.
PHASE EMISSION OF HAZARDOUS GAS
RISK Inhalation of vapours of hazardous gas
MEASURE
With a correct installation, concurring with the manufacturer prescription, using the
authorized chemical product and concurring with the rules in force in your country, the
machine don’t generate hazardous gas.
However the machine is supplied with vapours discharge, that have to be connected
concurring with the instruction on section 4.7.

REV_2.00_COD.500159_A4 PAG. 10
2.6 Safety signal used
To inform personnel operating on the machines of obligations of behaviour and residual risks, adequate safety signals
(as set forth by 92/58 EEC) are applied to the machine and near the work place.
GENERIC SAFETY SIGNALS:
In particular, labels with signals of obligation, prohibition and danger contained in this manual and pertinent to this
machine and most commonly used are:
Electrical risk Warning!
See annex documentation Caution hot surface
INDIVIDUAL SAFETY WEAR:
The evaluation of risks for the health and safety of workers carried out in the workplace and on any equipment used, as
well as the evaluation of residual risks as indicated, allow the employer to evaluate the need to adopt the individual
protection gear which is most suitable and appropriate to be provided to workers.
Considering the type of machine, it is felt that the individual protection gear should be provided to staff.
