• A third press on the Cycle button enables the user to reset the choice of cycle
Fig.25 – Full mode Fig.26– Partial mode Fig.27– Short mode
5.4.3 Selection of the instruments
By default, all instruments are selected. If you have less than 4 instruments, you need to manually select the
instrument to be reprocessed as well as the lubricant oil volume to be dispensed:
• Small drop corresponds to a normal volume (Short cycle)
• Large drop corresponds to a specific volume for certain contra-angles (long cycle for surgical or 1:5 contra-
angle for example)
• Unlit light indicators (3) indicate that the instrument is deselected and then the related instrument position will
not be activated
• By default, low oil volume is selected. Press the button corresponding to the position the instrument is
connected to, press once to select the large volume (large drop indicator) and twice to deselect the instrument
The volumes of the consumables to be dispensed and the sequence of injection of the products are
directly programmed and monitored by the device itself, according to an accurately defined and
validated protocol by a microbiological institute.
Except oil volume, the operating parameters cannot be modified.
5.4.4 Selection of the type of instrument
Your iCare+ enables to reprocess two kinds of instruments:
• Instrument with only one drive channel and without spray
• Instrument with 2 channels: both W/A and drive channels, with internal spray
All the different instruments that can be treated with iCare+ are mentioned in the following table for C3:
Instrument 1 Instrument 2 Instrument 3 Instrument 4
Only drive channel Contra-angle or handpiece with external spray / without spray
W/A and drive channel Turbine /Air scaler Contra-angle or handpiece with internal spray

RD 160.iCare+.OPM.ENG.V16 04.27.2020 p. 14
ENG
By default, instrument standard setting is “internal spray”. As illustrated in Fig. 28, to set external or without spray
instrument:
• Press “Spray” key and the key corresponding to the position of the instrument simultaneously
• To indicate that internal spray is disabled, the corresponding indicator is now illuminated
Fig.28– Without spray setting
If the internal spray is disabled by mistake or the internal spray is blocked, the unit detects it and will alert you. For
instance, this may occur in the following scenarios:
• An instrument has been selected as an “external spray instrument” (but in reality, the instrument has an
internal spray)
• An instrument that has been installed with external spray without using the button “ext W/O”
• An instrument which has been installed which has a blocked internal spray channel
In such a case the iCare+ will alert you to the issue:
• Unit will abort the cycle
• “Air warning Indicator” LED will blink
• Unit will emit an audible alert
• The position of the instrument is shown using blinking indicators (oil indicator and/or ext-WO).
Fig.29– Warning

5.5 Launching the reprocessing cycle
Once the reprocessing cycle is selected and instruments setting achieved, press the “Start Key” (K1) to launch the
cycle (see Figure 23).
• “Start Key” launches the selected cycle for the selected instruments. If a problem occurs or if you
wish to stop the cycle the “Start Key” stops the unit when pushed and held
• The cycle is then interrupted, the settings and selections are recorded and the device is in standby
mode. Pressing “Start Key” again, allows the reprocessing cycle relaunch from the beginning with
the same settings
• In case the door is open while the unit is in standby mode, the settings and selections are then reset
to default
When reprocessing cycle is launched, the status indicators on the control panel indicate the progress of the cycle
and the treatment chamber is illuminated using the same colour code.
• Yellow indicator = Cleaning phase
• White indicator = Disinfection phase
• Blue indicator = Lubrication phase
• Once the cycle is completed the green indicator is illuminated to inform the user that the instruments are ready
for further steps.
Fig.30– Indicators during cycle in progress
Caution
• When the “oil drop” indicators are switched off, the related instruments are not selected
• Before first use, or after a long period of no use, run the device without instruments
Caution
• In order to facilitate external cleaning, you need to perform pre-cleaning as defined in section 5.1
• Use disinfectant wipes to handle the instruments while connecting them to the unit
• At the end of the cycle, open the door and remove the instrument using a disinfectant wipe
Lubrication phase
Lubrication is a maintenance
step. Lubricants reduce
noise, friction and prevent
wear and accumulation of
wear debris. This step uses a
high pressure air blowing oil
inside the instrument.
Disinfection phase
Disinfection is the reduction
of the number of viable
organisms of the instruments.
The devices operates using
chemical disinfecting agents
which are used to neutralize
the remaining agents.
Purge and Initialisation
High pressure air is used for
