INSTRUCTIONS FOR RUNNING THE SET
6.1.
When the set remains inactive for long periods at a temperature below 0°C, it must be drained
completely. (fig.7)
7
MAINTENANCE
7.1.
To dismantle the Active Driver module:
a)
switch off the power supply and wait a few minutes;
b)
close the interception valves upstream and downstream from the module;
c)
drain off the water by means of the drainage cap on the rear of the Active Driver;
d)
slacken the unions upstream and downstream and extract the module.
After reassembling the module, fix the unions, open the interception valves again and prime the set as in points 5.2 a) and b).
The Active Driver must be calibrated as in the enclosed instruction manual.
7.2.
All our sets are subjected to strict testing of both the electrical and the hydraulic part.
It is unusual for malfunctions to occur, unless due to external or completely accidental causes.
7.3.
Below is a table with some suggestions on regulating the set in the event of irregularities in operation.

Suction pipe with insufficient diameter;
excessive us of couplings which cause
sudden variations in direction of the
suction pipe; siphon effect.
Suction pipe clogged.
Air infiltrations in the suction pipe of the
set.
Foot valve clogged or blocked.
Water recycling between the pumps in
the set.
Interception valves on suction of each
pump partly closed.

Check that the suction pipe is correctly
made, as indicated in the paragraph on
"Installation".
Clean it or change it.
Testing under pressure, check the perfect
seal in the couplings, the joins and the
pipes.
Clean it or change it.
Check correct operation of the non return
valves on suction of each pipe.
Open them completely.
THE SET DOES NOT START.

the electropump.
The circuit in the Active Driver is
interrupted.

The set chosen is undersized for the
characteristics of the system.
Excessive water consumption for the
flow rate of the well (set above head) or
of the first collection tank (set below
head or above head).
One or more pumps clogged.
Pipes clogged.
Foot valve clogged or blocked (set
above head).
Water recycling between the pumps in
the set.
Interception valves at suction and
delivery of each pump partly closed.
Air infiltrations in the suction pipe of the
set.

Change it, consulting the Technical
Catalogue.
Increase the flow rate that can be supplied
by the well or by the first collection tank.
Dismantle them and clean the pump body
and the impellers, ensuring that they are in
good condition.
Clean them or change them.
Clean it or change it.
Check correct operation of the non return
valves at suction of each pump.
Open them completely.
Testing under pressure, check the perfect
seal in the couplings, the joins and the
pipes.
