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.
