•Connections to external instruments.
The equipment can be hooked up only to other instruments that bear the CE mark.
•Electromagnetic interferences.
Use of electrical equipment that does not comply with standard IEC 60601-1 3rd Ed. - 2007 in the office or nearby may cause electromagnetic or other
types of interferences resulting in dental unit malfunctions.
In these cases it is recommended to shut off the dental unit power before using this equipment.
•Replacing the drills.
Operate the turbine release and contra-angle devices only once the drill has come to a complete stop. Failure to do so, will result in damaging the
locking system and drills could be released and cause injury. Exclusively use high-quality drills with a connection having a calibrated diameter. To
check the conditions of the locking system, make sure the drill is firmly secured to the instrument every day before starting work. Locking system
defects caused by misuse can be easily identified and are not covered by the warranty.
The drills and various instruments attached to the handpieces must comply with Biocompatibility Standard ISO 10993.
•Patients with pace makers and/or hearing aids.
When treating patients with pace makers and/or hearing aids, take into consideration the effects the instruments may have on pace makers and/or
hearing aids. Carefully read technical-scientific information available on this subject.
•Implants.
If the dental unit is used for implant operations using separate equipment designed for this purpose, you are recommended to shut the power off the
dental chair to avoid unwanted movements resulting from faults and/or accidental start-ups of the controls.
•Do not forget to turn off the office water supply and master switch of the equipment before leaving the surgery.
•The equipment is not protected against liquid penetration (IPX 0).
•The equipment is not suitable for use in the presence of a mixture of flammable anaesthetic gas with oxygen or nitrous oxide.
•This equipment must be stored properly so that it is kept in top working order at all times. The manufacturer shall not be held liable for misuse,
carelessness or improper use of the equipment.
•The equipment may only be used by authorised and adequately trained staff (dentists and paramedics).
•The user must be present at all times when the equipment is turned on or ready for start-up. In particular, never leave the equipment unattended in the
presence of children/ mentally disabled or other unauthorised personnel in general.

•Quality of the water delivered by the dental unit.
The user is responsible for the quality of the water delivered by the dental unit and must adopt measures to maintain the water quality.
To ensure that delivered water is kept to quality standards, CEFLA s.c. recommends equipping the dental unit with an internal or external disinfection
system.
The dental unit, once installed, is exposed to possible contaminants coming from the water mains. So, to effectively overcome this problem, it is
advisable to install the dental unit only when its use will be daily and to perform the disinfecting procedures starting from the day in which it is installed
by following the instructions set forth in the relevant sections.
If the dental unit is equipped with the air separation device from water mains (EN 1717), make sure that the expected continuous supply of disinfectant
is also carried out by ensuring that the relevant tank contains a suitable quantity of disinfectant (see relevant paragraph).
NOTE:
contact your local dealer or Dentists Association for more detailed information about national laws and requirements.
•Applied parts.
The parts of the equipment that come into contact with the patient while carrying out its functions correctly during standard use are: dental chair
upholstery, armrest, curing light fibre optics, syringe terminal, disposable camera protection, scaler bits, handpiece drills, suction tube terminals.
Non applied parts that may come into contact with the patient are: dental chair armrest support, dental chair lower casing, patient-side water unit
casing, water-to cup-spout, bowl, suction tubes, handpiece body.
WARNING:
Dental chair movement.
Make sure that the patient is ready to collaborate: ask
him/her to keep his/her hands and feet close to the body,
avoiding incorrect postures.
Check that the patient is sitting properly when moving the
dental chair (see figure).

A7 Plus –OPERATOR'S MANUAL

EN
1.4. CLEANING AND DISINFECTION
Cleaning is the first step of any disinfecting process.
Physically scrubbing with detergents and surface-active substances and rinsing with water removes a considerable amount of micro-organisms. If a
surface is not clean first, the disinfecting process cannot be successful.
If a surface cannot be adequately cleaned, it should be protected with barriers.
The outer parts of the equipment must be cleaned and disinfected using a product for hospital use with indications for HIV, HBV and tubercolocide
(medium-level disinfectant) specifically for small surfaces.
The various drugs and chemical products used in dental surgeries may damage the painted surfaces and the plastic parts. Researches and tests
performed show that the surfaces cannot be fully protected against the harsh action of all products available on the market. We therefore recommend
protecting with barriers whenever possible.
The harsh actions of chemical products also depend on the amount of time they are left on the surfaces.
It is therefore important not to leave the product on the surfaces longer than the time specified by the manufacturer.
It is recommended to use the specific medium-level disinfectant, STER 1 PLUS (CEFLA s.c.), which is compatible with:
•Coated surfaces and plastic parts.
•Upholstery.
WARNING:
The MEMORY FOAM upholstery will stain when splashed with mordant acid. Immediately rinse with plenty of water if acid splatters
on the upholstery.
•Uncoated metal surfaces.
If you do not use STER 1 PLUS, it is recommended to use products that contain at maximum:
•Ethanol. Concentration: maximum 30 g per 100 g of disinfectant.
•1-Propanol (n-propanol, propyl alcohol, n-propyl alcohol). Concentration: maximum 20 g per 100 g of disinfectant.
•Combination of ethanol and propanol. Concentration: the combination of the two should be maximum 40 g per 100 g of disinfectant.
WARNING:
•Do not use products containing isopropyl alcohol (2-propanol, iso-propanol).
•Do not use products that contain sodium hypochlorite (bleach).
•Do not use cleaners that contain phenols.
•Do not spray the selected products directly on the surfaces.
•All products must be used as directed by the manufacturer.
•Do not mix the STER 1 PLUS disinfectant with other products.
WARNING:
The products suggested are compatible with the materials of the equipment, however damages may occur to surfaces and
materials resulting from the use of different products, even if not included in the above list of excluded products.
Cleaning and disinfecting instructions.
Clean and disinfect with disposable non-abrasive paper (avoid using recycled paper) or sterile gauze.
Do not use sponges or, in any case, any material that can be reused.
WARNING:
•Turn off the dental unit prior to cleaning and disinfecting the external parts.
•All materials used to clean and disinfect must be thrown away.
