7.7 — LIGHT FUNCTION (present in version L)
This function is present in the Minilight L version. In this
model, the handpiece has an optical fibre that conducts the
light generated by a LED located in the body of the syringe.
We recommend using a switch to turn the LED on and off.
For connections, see wiring diagram 14.2.
NOTE
• The sole function of the selector switch is to preselect
warm operations. The water and/or air are only heated
at the moment in which they are actually used.
• The cleaning (or line washing) procedures must always
be performed in the cold position.
WARNING
Do not use the tip improperly. Remove and sterilise the tip
after each patient.
IMPORTANT
Air and water must be able to flow freely from the tip. Do not
rest the tip on the tooth or on an object. Do not press the tip
against impression materials as they could cause obstruction
After each use on a patient, the handpiece and tip
of the syringe MUST be cleaned and sterilised to
guarantee maximum hygiene.
