4.10 ELECTRICAL CONNECTIONS DIAGRAM FOR ASPIROMEC LE
4.11 INSTALLATION OF SMOKE SUCTION UNIT ON ASPIROMEC LE / ASPIROTRONIC LE
See the diagram on the right for the connections of the power
supply, the circulating pump, the fan and the additional
circulating pumps. If the plant is only equipped with one
circulating plant and one room temperature thermostat then the
first must be connected to terminal pins 6 and 7 and the second
to pins 4 and 5.
Connections which are different to those indicated and arbitrary
modifications void the warranty.
If, on the other hand, the plant consists of several areas fed by
the same number of circulating pumps then one area and its
corresponding circulating pump and room temperature
thermostat must be selected to function as a thermal safety
device.
These are to be connected as described above to pins 6-7 and
4-5.
All the other circulating pumps will have to be connected directly
to pins 11 and 12, if the overall load does not exceed 5 Amperes,
or by means of relays if the load is greater.
The corresponding room temperature thermostats must be
inserted in series on the corresponding power supply lines. This
type of connection will guarantee that the circulating pumps
function as anticondensation devices and consequently will not
be able to function if the water in the boiler is below 60° C.
Install the smoke suction unit after
mounting the outer casing.
Firstly mount the ceramic fibre gasket (2).
Then mount the smoke suction unit (1) on
the centring pins on the boiler.
Then secure it using the fasteners on the
boiler.
Make sure that after it has been secured
the safety spring on the fasteners is
attached; this prevents the smoke suction
unit from accidentally coming off.
Then connect the unit plug.
