6.1 — CONNECTION TO ELECTRICAL SYSTEM
The connection involves hooking up the two electrical
terminals to the transformer, arranged to provide an output
of 24 V (see wiring diagram 14.1). Model L only: voltage for
LED light 3.3 Vdc: black wire (+), white wire (-)
NOTE
• The electric power supply and transformer used must
be rated Safe Extra Low Voltage (SELV) for medical use, in
compliance with the mandatory regulations.
• Connection to terminals with output voltage exceeding 24
V could irreparably damage the unit and compromise safety.
6.2 — CONNECTION TO HYDRAULIC SYSTEM
The syringe’s green line must be hooked up to the water
supply.
NOTE
• The operating pressure is 250 kPa. A slight increase in
pressure would only increase the power of the jet, but
would not create any problems and is not dangerous.
• The water used must be potable water, filtered (<25 μm)
and free of bacteria, etc.
• For the syringe to function properly, the water pressure
must not be lower than indicated.
6.2 — CONNECTION TO COMPRESSED AIR SYSTEM
The syringe’s blue line must be connected to the compressed
air system.
NOTE
• The recommended operating pressure is around 450
kPa.
• When using the Minilight syringe, national regulations
regarding water and air quality must also be met.
• The air must be medical grade, dry and free of oil and
bacteria – a 5μm air filter is recommended.
6.4 — CONNECTION OF STRESS ABSORBER CORD
The stress absorber cord must be anchored to the dental

IMPORTANT NOTE:
With each syringe, the package also includes a User’s manual
which also includes a “Fault Report Form”. Since this is
required by law, the user must receive this User’s manual.
Therefore, the syringe installer is responsible for delivering
these forms to the dentist. Directive 93/42/EEC requires
product traceability: therefore, our customers are asked to
ensure that we can identify the end customer to whom the
product has been sold.
