2. Operating the lamp Quintaflex
2.1 Checking the lamp Quintaflex with light intensity control
The lamp Quintaflex is optionally equipped with the function of electronic light intensity control. You can
adjust the light intensity at the key pad on the cardan bow.
♦ Voltage measurement and setting
Before using the OT-lamps, a voltage measurement and, if necessary, a voltage setting has to be done.
Only in this way a perfect functioning can be ensured.
If the location of the lamp is changed, the voltage measurement and setting must be repeated.
♦ Voltage measurement at the halogen bulbs
Screw
To measure the voltage proceed as follows:
Mount the lamp to the ceiling or wall attachment.
Switch on the lamp.
In order to make the measurement, remove the
cover.
The cover is fixed with two screws, as shown in the
figure. Loosen the two screws, remove them and
take off the cover.

Measuring points
Measuring points
♦ Voltage setting at the halogen bulbs
The measuring points for checking the voltage are
in the same position at all Quintaflex-lamps.
The measuring points are shown in the figure.
At measuring points 1 + 2 measure the voltage
applied at the halogen bulbs. The lamp is set to
the maximum light intensity.
The AC or DC voltage depends on the external
power supply.
Rated voltage 22,8 – 23,8V.
If the voltage measured is too high or too low, the
value must be adjusted at the power supply.
The setting at the transformer is made by reconnecting the wires on the secondary side.

♦ Voltage measurement at the control board
Please check, whether the power supply is supplying AC or DC.
Voltage measurement at DC
Pay attention to the polarisation during the installation.
If the light intensity control does not function as desired, the PLUS- and MINUS-pole at the power
supply have to be changed.
Voltage measurement at AC
For installation at AC proceed as described below:
• Preparation
The lamp is already switched on. Set the lamp to
the lowest light intensity
• Measurement
Measure the voltage at measuring points 3 + 4. The
voltage must be less than 40V DC.
If this value is exceeded, reset it as described below:

3. Cleaning
V
1
Cleaning / disinfection and sterilisation
Basics
Efficient cleaning / disinfection is an essential requirement for effective sterilisation of the handle.
Within the scope of responsibility for the sterility of the products it should be noted that only sufficiently
validated equipment and product specific processes are used for cleaning / disinfection and that the validated parameters are complied with in every cycle.
In addition, the hospital / clinic hygiene regulations must be observed.
3.1 Sterilizable handle
At delivery the lamp is equipped with the handle
sleeve 1. The handle sleeve is removable and ster-
ilisable. Before using the first time and before every
use the handle sleeve must be cleaned, disinfected
and sterilised.
The handle sleeve must be removed for sterilisation:
• To remove press the lock V and pull off the
sterilisable handle sleeve 1 while keeping the
lock pressed.
• To attach, push on and slightly twist the handle
until the lock V engages securely.
Handles often become unsterile during an OP;
therefore always keep additional handles available
for exchange.
Cleaning / disinfection
Cleaning and disinfection must be carried out immediately after use.
A mechanised process (disinfector) should be used for cleaning / disinfection. The efficiency of the process used must be recognised and validated in principle (e.g. listed under disinfectants and disinfection
procedures tested and recognised by Robert-Koch-Institute / DGHM).
When using other procedures (e.g. a manual procedure), proof and process efficiency in principle must
be provided within the scope of validation.
Proof in principle of the suitability of the handles for efficient cleaning / disinfection was provided using a
cyclic cleaning system (Netsch-Bellmed T-600-IUDT/AN, programme 2 for small parts; code B).
It is not allowed to use agents / disinfectants, which contain the following substances, as these may
cause changes in the material:
- High-concentration organic and inorganic acids
- Chlorinated hydrocarbons
- 2-ethoxyethanol
59250002 Edition 02 18.06.2002 / Bak Page 7/20
Quintaflex Ceiling Model
When cleaning / disinfecting, the following procedures must be followed:
Process Time (sec.)
Zone 1 Pre-rinse, external, cold, 10 – 15°C 45 Washing, acidic, external 35°C 120 Draining time 10 Re-rinse, external approx. 80°C *10 Draining time *15 Re-rinse, external approx. 80°C *15 Draining time 15

≈ 5 minutes
* When occupying the disinfection zone (washing zone 2), the re-rinse and draining times will depend on
the respective objects being washed therein!
Sterilisation
Only previously cleaned and disinfected handles may be sterilised.
The handles are placed in a suitable sterilisation pack (one-way sterilisation pack, e.g. foil / paper sterilisation bags, single or double pack) in accordance with DIN EN 868 / ISO 11607 for steam sterilisation
and then sterilised.
Use only the sterilisation procedure listed below for sterilisation. Other sterilisation procedures (e.g. ethylene oxide, formaldehyde and low-temperature plasma sterilisation) are not permissible.
Steam sterilisation procedure
Validated in accordance with DIN EN 554/ISO 11134
Maximum sterilisation temperature 134°C
Proof in principle of the handles’ suitability for effective sterilisation was provided using a fractional vacuum process (Euroselectomat 666 by MMM Münchner Medizin Mechanik GmbH, sterilising temperature
134°C, holding time 7 min.)
Inspection / durability
The handles should be inspected for damage and changed before re-use, if required.
The handles may be cleaned / disinfected, sterilised and re-used for a maximum of 1000 times. If the
handles are re-used more than 1000 times, then this will be the responsibility of the hospital / clinic.

4.3 Changing of spare parts
4.3.1 Changing the halogen bulbs
Dr. Mach uses special halogen bulbs as illuminants.
Only original Dr. Mach replacement bulbs may
be used.
The use of other bulbs can lead to a considerable
reduction of the light power and increase in the
thermal load.
To change the halogen bulbs proceed as follows:
• Turn off the lamp.
• Rotate the three quick-release fasteners 1 half
a turn anticlockwise so that the corresponding
disk bearer can be removed from the bottom
part of the lamp housing.
• Press outward security clip 2 and turn shade-
holder 3 down.
• Carefully remove the halogen bulb 4 (22,8-24V/
50W) from its socket, change and replace.
• Replace shadeholder and the disk bearer onto
the bottom part of the lamp housing and rotate
the quick-release fasteners 1 clockwise.
Do not touch the halogen bulb with naked hands.
Remove stains with a clean cloth and alcohol, since
otherwise these can burn into the glass and lead to
early failures.
Remark:
The halogen bulbs have a service life of approx. 1000 hours without any deterioration in
their luminosity.
If after approx. ½ year of average use of eight
hours daily one of the halogen bulbs should fail, we
recommend that the whole set should be replaced.
4.3.2 Changing the fuses
The necessary fuses are provided by the customer.
Pay attention to the instructions from the local
installer!
