cooler's front panel. Then connect the filter unit
to the snap connector and fasten the unit to the
mounting plate. Inside the cooler there is a flow
switch, factory­adjusted to 1 litres per minute. To
change the flow rate, loosen the locking screws
of the black slide control and move it to show the
desired flow rate.
2. Connect the mains voltage and control connectors
of the cooler unit to the corresponding connectors
on the base of the power supply. The connection
can be established through the base of the power
supply when the devices are separated or through
the right side of the A7 Cooler unit by removing
the right side plate.
