Cleaning Mechanical cleaning
Place the electronic motor in the strainer basket after
pre-cleaning.
Mechanical cleaning is only successful if the pre-
cleaning described above is adhered to!
Cleaning is done using the VARIO TD programme in the
cleaning and disinfection unit (RDG). For the cleaning
process it is advisable to use DI water (fully desalinated
water).
After completing the cleaning programme (incl. thermal
disinfection) check the electronic motor, motor cover
with cable and handpiece carrier for visible
contamination in the grooves and gaps. Repeat the
cleaning if necessary.
Disinfection Mechanical disinfection
The cleaning/disinfection unit has a thermal disinfection
programme which follows the cleaning. When
performing mechanical thermal disinfection, give due
consideration to the national requirements relating to
the A0 value (see DIN EN ISO 15883-1). We recommend
an A0 value of 3,000 for the electronic motor.
Disinfection must be carried out with DI water.
Drying Mechanical drying
Dry the electronic motor using the cleaning/disinfection
unit's (RDG) drying cycle. If required, manual drying can
also be achieved by using a lint-free cloth. When drying
manually, take particular care with the grooves and gaps
of the electronic motor. Then spray the electronic motor
again with NouClean spray.
Every RDG must provide a corresponding drying
procedure through the manufacturer (see ISO 15883-1).
Please follow the corresponding RDG-manufacturer's
directions and operating instructions.
Inspection 1. First unscrew the motor cover and remove the cable incl. the motor cover. Unscrew the handpiece carrier
and care and remove it also.
2. Perform a visual check for damage, corrosion and wear.
3. In the next step spray the electronic motor for cleaning and care. Nouvag AG recommends using
NouClean spray for this purpose. Screw the spray attachment (fig. 1) in place of the connector onto the
motor and spray with NouClean spray for about 3 seconds (fig. 2) until only clear liquid runs off the
electronic motor.

4. Then wipe down with a moist cloth (Follow the product's instructions for use).
5. After spraying the electronic motor screw the handpiece carrier and the motor cover with the cable back
onto the electronic motor (see figs. 3 – 4).

Warning
When inadequately rinsed or exposed to the
disinfectant or detergent for too long, the
electronic motor can corrode. Please see the
corresponding detergent and disinfectant's
package insert for dwell times.
Manual drying
Set the electronic motor up in an upright position
without motor cover and cable and without
handpiece carrier.
Dry the electronic motor for at least 30 minutes.
Then spray with NouClean spray. Afterwards
screw the handpiece carrier and the motor cover
with cable back onto the electronic motor (see
fig. 4).
