Safety rules
WARNING!
•
All equipment is permanently installed.
Depending on the type of chair the unit comes with, refer to the installation DATA given in paragraph “Specifications”.
CEFLA s.c. shall not be held liable for any personal injury or equipment damage resulting from failure to heed the precaution given above.
•
Floor condition
The floor conditions (continuous type) must meet design load standards set forth in DIN 1055 sheet 3.
The weight of the dental unit including a patient weighing 190Kg, is approximately 350Kg/mq.
See the Installation manual for further details about installation.
• This device may not be modified in any way without the authorisation of the manufacturer.
If the device is modified, appropriate examinations and tests need to be conducted in order to ensure continued safe use.
CEFLA s.c. shall not be held liable for any personal injury or equipment damage resulting from failure to heed the precaution given above.
•
Dental chair
The maximum chair capacity is 190 Kg. This weight must never be exceeded.
•
Tray holders
The maximum weights that can be held must never be exceeded:
- Instrument tray attached to the instrument board maximum allowable load 2 Kg, evenly distributed.
- Instrument tray attached to the instrument board maximum allowable load 1 Kg, evenly distributed.
•
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 to standard IEC 60601-1 3.a Ed. - 2007 in the office or nearby may cause electromagnetic or other
types of interferences resulting in dental unit malfunctions.
In these cases, shut off power to the dental unit before using this equipment.
• Replacing the chucks
Operate the turbine release and contra angle only once the chuck has come to a complete stop. On the contrary, the locking system will wear down
and the chucks can slip off causing injury. Use only high quality chucks with gauged diameter attachment. To check the state of the locking system,
make certain the chuck is firmly secured to the instrument every day before starting work. Locking system defects caused by misuse are easily
identified and not covered by the warranty.
• 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, shut off power to the dental chair to avoid
unwanted movements resulting from faults and/or accidental start up of the controls.
• Do not forget to turn off the office’s water supply and master switch on the equipment before leaving the surgery.
• The equipment is not protected against liquid penetration (IPX O).
• This equipment is not suitable for use in the presence of a mix of inflammable 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 responsible for misuse,
carelessness or improper use of the equipment.
• This equipment is to be used exclusively by qualified personnel (doctors and paramedics) with the proper training.
• 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/the mentally disabled or other unauthorised personnel in general.
Any companions must keep out of the area in which treatment is performed and in any case under the responsibility of the operator. The area in
which treatment is performed refers to the space around the dental unit plus 1.5 meters.
•
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 it.
To ensure that you meet the water quality requirements, CEFLA s.c. advises you to equip the dental unit with an internal or external disinfection system.
Once installed, the dental unit is exposed to contaminants originating from the water supply. For this reason, it is recommended to install and put it
into operation only when you begin using it daily and to perform the decontamination procedures described in the relative chapters right from the first
day of installation.
If the dental unit is equipped with a device for separation from the open water supply system (EN 1717), make sure that it also continuously adds
disinfectant as required and check that the relative tank contains an adequate quantity (see the relative paragraph).
NOTE:
Contact your local dealer or Dental association for more detailed information about national laws and requirements.
