4. ELECTRICAL CONNECTION OVERALL DIMENSION
Electrical installation must only be completed by an authorised and trained technician in
line with Australian safety regulations. The electric installation should be provided by a
system of multiple separations with contact openings of at least 3 mm. The protection
of the system will be made by a dierential switch (1fn=30mA.) The electric cable must
correspond with Australian standards and be sucient for the load generated. The single
phase motors have a built-in thermal protection. Look at the schematic drawing on Fig(1)
for a correct electrical connection. KEEP AWAY FROM CHILDREN.
5. CONTROLS PRIOR TO THE INITIAL STARTING
Check that the voltage and frequency of the electric supply correspond to that indicated
on the technical characteristics label. Make sure that the shaft rotates freely. Fill pump
body with water, unscrewing slightly the priming plug. Verify the motor sense of rotating as
indicated on the fan cover. THIS PUMP SHOULD NEVER BE DRY OPERATED.
6. STARTING
Open all gate valves installed in the suction ( LINE ), connect to the electric supply switch,
wait for the priming to be completed. If a foot valve has been installed, the priming will be
instantaneous. If the motor fails to start, or does not deliver water. Refer to our trouble-
shooting guide with the possible problems and subsequent actions to take.
7. MAINTENANCE
Bromic electro pumps do not require special maintenance. The pump body must be
drained during periods of low temperatures (temperatures below 1°C) or long period of
inactivity. If the pump is inactive for over 60 days, the pump should be cleaned and stored
in a dry and ventilated place.

4.Electrical connection
The electric installation should be provided by a system of multiple separations with contact openings of at
least 3 mm.
The protection of the system will be made by a differential switch (1fn=30mA.) The electric cable must
correspond to the EEC(2) norm or to the type H07 RN-F according to VDE 0250.
The single phase motors have a built-in thermal protection.
Look at the schematic drawing on Fig(1) for a correct electrical connection.
5.Controls prior to the initial starting
Check that the tension and frequency of the electric supply correspond to that indicated on the technical
characteristics label.
Make sure that the shaft rotates freely.
Fill pump body with water, unscrewing slightly the priming plug.
Verify the motor sense of rotating as indicated on the fan cover.
THIS PUMP SHOULD NEVER BE DRYOPERATED.
6.Starting
Open all gate valves installed in the suction and connect the electric supply switch and wait for the priming
to be completed. If a foot valve has been installed. the priming will be instantaneous.
If motor fails to start or does not deliver water.
Refer to our trouble Shooting list with the possible problems and consequent actions to take. This
information will be found on the next pages.
7.Maintenance
Our electro pumps do not need any special maintenance.
Pump body should be drained during periods of low temperatures or long period of inactivity. If this inactivity
last longer, pump should be cleaned and kept in a dry and aired place.
