Caution! Contact with the appliance is dangerous. High temperatures occur during and
after use. Beware of hot surfaces and the danger of fire if, contact is made by flammable
objects
At a predetermined place, position the suction unit on the base (Fig.2) and remove all transport packaging
and fixings. Connect both hoses to their relative inlet and outlet ports of the pump. Prepare the required
electrical connection between the pneumatic control module and suction unit as below:
Connections under floor – suitably shorten both hoses and
connect them to the prepared pipes protruding up through the
hole in the base. Connect the 24V signal wire from the dental
chair to the terminals – 1 & 2 – and connect the power cord to
terminals - PE & U & N - inside the switching block.
Connection above floor – direct power cord and both hoses to
the rear of the base. Thread the 24V signal wire from dental
chair through the rear hole of the box and connect to the
terminals in the switching block. Position the box to face the
right direction, and place over the suction unit whilst at the
same time, thread both hoses and power cord through the rear
hole of the box. When positioned correctly, plug the power cord
in the electrical socket.

11.1. 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.
11.2. Electrical connection
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.
