2 Safety
Dürr Dental has designed and constructed this
unit so that when used properly and for the in-
tended purpose it does not pose any danger to
people or property. Nevertheless, residual risks
can remain. You should therefore observe the
following notes.
2.1 Intended purpose
The purpose of the place selection valve is to
specifically open the volume flow between the
suction unit and the hose manifold.
2.2 Intended use
The installation position and technical data must
be observed. Installation as a suction valve in a
dental treatment unit or in other areas of a den-
tal suction unit for one treatment chair. Only the
media associated with dental treatment
(e.g.water, saliva, dentine and amalgam) must
be suctioned.
2.3 Improper usage
Any other usage or usage beyond this scope is
deemed to be improper. The manufacturer ac-
cepts no liability for damages resulting from im-
proper use. In these cases the user/operator will
bear the sole risk.
2.4 Systems, connection with other
devices
Additional devices connected with medical elec-
trical devices must be proven to conform with
their corresponding IEC or ISO standards. All
configurations must continue to comply with the
standard requirements for medical systems (see
IEC 60601-1).
Whoever connects additional devices to medical
electrical devices automatically becomes the
system configurator and is responsible for en-
suring that the system corresponds with the
standard requirements for systems. Local laws
take priority over the requirements outlined
above.

Product description
5 Operation
Place selection valve closed
The solenoid valve on the place selection valve is normally open. Atmospheric pressure enters be-
tween the valve cap and membrane through a small channel. The membrane therefore rests on the
valve body and interrupts the suction power.
1 Solenoid valve
2 Valve membrane
Place selection valve open
If the suction hose is taken out of the hose manifold, a voltage is applied to the solenoid valve on the
place selection valve and the solenoid valve is actuated. With the vacuum of the suction unit, the vol-
ume between the valve cap and membrane is drawn by suction until it is empty and the membrane is
consequently raised. The raised membrane therefore releases the suction power in the place selec-
tion valve.

7 Installation
Prior to working on the device or in case
of danger, disconnect it from the mains
(e.g. pull the mains plug).

6 Requirements
6.1 Setup options
– Installation in treatment units in dental surger-
ies or dental clinics.
– Installation outside the treatment unit in the
suction system (e.g.for 12 o'clock suction).
6.2 Hose materials
For waste connections and suction lines only
use the following hose types:
– Flexible spiral hoses made of PVC with inte-
grated spiral or equivalent hoses
– Hoses that are resistant to dental disinfectants
and chemicals
Plastic hoses will display signs of ageing
over time. Therefore, they should be in-
spected regularly and replaced as neces-
sary.
The following types of hoses must not be
used:
– Rubber hoses
– Completely PVC hoses
– Hoses that are not sufficiently flexible
6.3 Information about electrical
connections
