5 MAIN CAUSES OF FAILURE TO
FUNCTION
If the additive is not injected the User must verify and
check:
-
whether there is any of the product to be
consumed in the storage tank
-
whether the filter is blocked
-
whether the electric current is on
If faults occur or are found that are different to the
above, such as:
-
difficulty in sucking up the product to be
injected
-
rapid and continuing emptying of the suction
pipe after each functioning
-
breakage of the pumping pipe
-
breakage of the motor reducer
-
breakage of the electronic card
It is a good idea to contact a Service Centre as
maintenance is necessary.
For a rapid and efficient intervention it is important
when calling to indicate precisely the model of the
pump, which can be seen on the data plate.
6 MAINTENANCE AND CLEANING
Before carrying out any type of maintenance
work on the device you must turn off the power
and remove the plug from its socket.
The component that needs maintenance is:
-
the pumping pipe (fig. 8)
the efficiency of the pump is linked to this
component so it must be periodically replaced, at
least every 3 months, in order to guarantee a
constant capacity to the device itself. This also
prevents the pipe from breaking through wear.
Maintenance on this component must be carried out
by competent and professionally qualified personnel
from a Service Centre and demanding the use of
original spare parts.
The component that needs cleaning is:
-
the suction filter (fig. 9)
The filter will have to be periodically washed in case
the additives used contain sediments that prevent
the product being sucked up to the pump itself.
The state of the filter must be checked each time
the pump is refilled with the product. When cleaning
the filter protect your hands with rubber gloves.
6.1 PERIODICAL CHECKS
The device must be periodically checked and if
necessary refilled with the consumed product. Also
verify that there are no leaks in the water circuit.
7 PERIODS OF NON-OPERATION
If a long period of non-operation is expected,
when the pump is going to be used again an extra
repair must be carried out, replacing the pumping
pipe (fig. 8)
This operation is necessary because the product that
has remained in the pipe tends to solidify removing
the natural elasticity of the pumping pipe.
Skilled and qualified personnel must carry out this
maintenance.
8 DIRECTIONS FOR THE
MAINTENANCE FITTER
All the operations that entail working on circuits
or internal parts, for the performance of which
electrical protection devices have to be removed,
must be carried out with the device stopped and
only after having turned off the voltage.
