use and maintenance booklet - safety instructions
WARNING:
Check that the submersible pump has been primed. In some cases, an air bubble may form in the upper part of the pump body,
which prevents liquid pumping.
1.7.1 Mobile post (Fig. 1)
Using a hose union, connect the delivery pipe to a hose with an internal
reinforcement coil and a diameter which is the same size as or larger
than the electric pump outlet.
1.7.2 Fixed post (Fig. 2)
Connect the electric pump to a metal piping, fitting a non-return valve
and an interception gate valve on the said metal piping. This ensures
the pump stability is guaranteed by the piping.
The pump can also be connected to polyethylene piping, using the
relative union. Connect the electric pump to the earth using the PVC
insulated fork.
1.7.3 With the joining foot (fig. 3)
Designed for the horizontal outlet models. Fix the joining foot to the
bottom of the tank first, using expansion plugs. Install the delivery pipe
with the relative non-return valve and gate valve.
Engage two guide pipes on the joining foot, fixing them in the upper
part using the spacer bracket provided by the manufacturer.
This way, the pump can be lowered supported with a galvanised chain
or cable hooked around the handle and, thanks to the two guide pipes
it will fit perfectly in place on the foot.
1.8 Electrical connections
All the operations involved in the connection to the electrical network must be carried out by skilled labour and in compliance with the
legislation in force.
WARNING:
In the wiring-up stage, connect the yellow-green earth conductor first, then the others.
For the protection of the electric motor and the safety of the people in the vicinity, connect the pump to a suitably-scaled differential overload
switch.
WARNING:
for the single-phase versions it is compulsory to avoid a high number of start-ups per hour in order to maintain the capacitor in
the best condition.
Before installation make sure that:
•
the power line has an earth and complies with the regulations in force
•
the pump’s and float switch cables are not damaged
