Control-Box.
4.6.2 Connecting the Electric Appliances
 Connect the electric appliances to the appliance socket connections (16, Fig. 5) on the QCB
(A, B, C, D). Observe the allocation of the socket connections – suction channel / pinch valve.
When connecting the electronic equipment to the Quattro Control-Box, ensure that the total
sum of currents from the connected electrical appliances does not exceed the maximum per-
missible load on the Quattro Control-Box (see section 8.2, Technical Data).

and the number of open suction channels. If the extraction unit is running at its maximum level,
it may occur that one particular suction point does not achieve its full potential.
In this case, in order to increase the suction level at this particular suction point, it is necessary
to close one or more other suction channels.
