3.6 Installations
Danger
All installation operations should be
performed while the electropump is
disconnected from the mains.
Warning
Do not install the machine in environments
containing gases and/or inflammable or
explosive materials.
Danger
Electropumps are designed so that all the
moving parts are rendered inoffensive by
means of protections. Do not use the
electropump if these protections have been
removed or are damaged, since this could
cause serious accidents to people.
Danger
The machine supply line should always
have a differential circuit breaker.
3.6.1 Assembly
- The arrows printed on the machine body indicate the
direction of the flow.
- It is advisable to fit gates downstream and upstream from
the machine.
- The machine should be installed so that the axis of the motor
is between the vertical and horizontal direction in all
positions.
- The motor should never be arranged in a low position to
avoid water entering the motor and the bearings. See the
following figure for reference.
R4T – R2T
R4TD – R2TD
- Install the machine on horizontal or vertical pipes, on the
“delivery” and “return” lines.
- The machines used do recirculate used water should always
be installed on the vertical section of the pipe so that the
water flow is directed upwards.
- The system should also be equipped with an air venting
system on the section of the pipe where the machine is
installed.
- If the machine is installed on a vertical pipe with the flow
directed downwards, the air vent should be fitted on the
highest point of the machine.
- Do not install the machine in the lowest point to protect it
from deposits.
- To guarantee a regular suction pressure and avoid noise
and cavitation, the pipe connected to the expansion vessel
should be installed before the suction mouth of the machine.
- Verify that the machine is not subject to tensions caused by
pipes or water temperature variations.
- The machines can be directly inserted in the pipes if these
are appropriately supported. The threaded holes on its base
can be used to fix the machine to a support (see PRODUCT
SPECIFICATIONS – DIMENSIONS AND WEIGHTS).
- To avoid deposits from accumulating in the machine and in
the valves, drain the system before starting the machine.
- It is advisable to install anti-vibration supports on both
flanges and on the base to prevent vibrations from being
transmitted along the pipes.
3.6.2 Connection of the machine to the pipes
Check valves should be installed both upstream and
downstream from the machine, to avoid having to drain the
whole system when it is necessary to disassemble and remove
the machine.
Before pipes are installed, it is necessary to make sure that
they do not exert mechanical stresses on the machine.
It is necessary to make sure that the diameter of the suction
and delivery pipes is appropriate and that the minimum inlet
pressure is guaranteed (see 2.2 “Technical characteristics”).
To avoid sediments from accumulating inside the machine, it is
advisable to avoid installing the machine in the lowest point of
the system.
Tubes must be installed in a position that prevents air from
accumulating, especially on the suction side.

PIPE ASSEMBLY
Incorrect Correct
Accumulated
air
Warning
The pump should never be started if the
check valve on the delivery side is closed,
because this would increase the
temperature of the fluid inside the pump.
The accumulation of steam could cause
cavitation, which could damage the moving
components.
If the valve can operate with a closed valve,
it is advisable to ensure a minimum fluid
flow by means of a by-pass or a drain. The
drain can also be connected to a collection
reservoir every time it is necessary to
provide a minimum flow equivalent to at
least 10% of the rated one in the maximum
yield point. Flow rate and head in the
maximum yield point are printed on the
pump nameplate.
3.6.3 Air vent
Considering that the mechanical seal is water lubricated, the
machine should be operated only after the machine and the
system have been filled with water and vented from air. The air
is vented from the pump through a special vent valve.
VENT VALVE
This operation doesn’t need to be performed on machines
installed on vertical pipes with flow directed upwards.
For twin machines with horizontal or vertical shaft, this
operation should be performed by loosening the 1/8” cap on
the pump housing.
Sometimes the air venting operation needs to be repeated
several times to completely remove the noise originating from
the presence of air in the pump.
3.6.4 Terminal block positioning
Warning
Before performing any operation, make
sure that the pump is not connected to the
power supply and that it cannot be started
accidentally.
The terminal block can be rotated in any position by 90° steps.
To change the position of the terminal block, perform the
operations described here below:
1. If necessary, use a screwdriver to remove the grid that
protects the motor-pump coupling. Do not remove the
coupling.
2. Remove the screws that fix the motor to the pump body.
3. Turn the motor in the desired position.
4. Reposition and tighten the screws.
5. Reassemble the protection grid.
3.6.5 Connection to the mains
Danger
The installer will have to make sure that the
electric supply system has an adequate
grounding compliant with the laws in force.
Danger
Check that the supply system has a
differential switch with a degree of
sensitivity of ∆= 30 mA (DIN VDE
0100T739).
Danger
Before removing the cover from the
terminal block of the motor and before
performing operations on the machine,
make sure that the supply line has been
cut-off.
