9.1. Vacuum Connection
Two hoses, one for suction (1) and one for exhaust (2) are
connected to the suction pump (Fig.3). The hoses are inlet
(1) and outlet (2) of the pump. They protrude through the
rear hole of the box, or they are connected to the pipe-work
under the floor. Suction (vacuum) hose is connected to the
separator/pneumatic control module at the dental chair, and
exhaust hose is vented away from the surgery to the
environment outside of the building.

Plug the electrical cord into the mains.
The appliance is equipped with a grounded plug. Make sure this connection complies with
local electrical codes. The mains voltage and frequency must comply with the data stated

on the appliance label.
 Keep the socket easily accessible to ensure that in an emergency the appliance can be safely
disconnected from the mains.
 Connection to the power distribution box must be max.16 A.
 Power between the suction unit and pneumatic control module on the dental chair, is 24V provided by
wires connecting to a PCB in the switching block (CP1).
If any electrical cord or air hose is damaged it must be replaced immediately.
