6.4. Installation
See installation examples, chap. 14 fig. 1 and 2.
The pumps must be installed with the rotor axis in the
horizontal position and with the feet under the pump.
Place the pump as close as possible to the suction
source.
Provide space around the pump for motor ventilation,
for checking the direction of rotation of the shaft,
for filling and draining the pump and to allow for the
collection of the liquid to be removed.
6.4.1. Pipes
Make sure that the insides of the pipes are clean and
unobstructed before connection.
ATTENTION: the pipes should be secured to their
supports and connected in such a way that they
do not transmit stress, strain or vibrations to the
pump (par. 14 fig. 3).
Tighten the pipes or union coupling to the extent
sufficient to ensure a tight seal.
Excessive tightening may cause damage to the pump.
The pipe diameters must not be smaller than the pump
connections.
6.4.2. Suction pipe
The suction pipe must be perfectly airtight and be led
upwards in order to avoid air pockets.
With the pump located above the water level (suction
lift operation, chap. 14. fig. 2) fit a foot valve with
strainer which must always remain immersed.
If operating with flexible hoses use a reinforced
spiral suction hose, in order to prevent the hose from
narrowing due to suction vacuum.
With the liquid level on the suction side above the
pump (inflow under positive suction head, chap. 14.
fig. 1) fit an inlet gate valve.
ATTENTION: the pump is equipped with non-return
valve built into the pump suction, in order to fill the
suction pipe there must be a filling system on the
suction pipe (chap. 14 fig. 4).
Follow local specifications if increasing network
pressure.
Install a filter on the suction side of the pump to
prevent foreign particles from entering the pump.
6.4.3. Delivery pipe
Fit a gate valve in the delivery pipe to adjust delivery
and head.
when the geodetic difference in level in the delivery
section is over 15 m fit a check valve between the
pump and the gate valve in order to protect the pump
from water hammering.
ATTENTION It is necessary to check that the restart
pressure (subtraction between
compatible with the actual pressure of the pump and
of the water column of the system.
6.5. Electrical connection
OFF
The electrical connection must be carried out
only by a qualified electrician in accordance
with local regulations.
Follow all safety standards.
META_S_Rev100000277_01-s13 - Operating Instructions
Make sure that the frequency and mains voltage
correspond to the values indicated on the plate.
For use in swimming pools (only when there are no
people in the pool), garden ponds and similar places,
an F-type residual current device with IΔN not
exceeding 30 mA must be installed in the supply circuit.
Install a device for disconnection from the mains
(switch) with a contact separation of at least 3 mm in
all poles.
The pumps are supplied with with a built-in thermal
protector and with a plug.
Connect the plug to a socket with an earth lead.
The motor will stop if overheating is detected.
When the windings cool down, the thermal protector
enables re-starting.
The pumps are supplied with power supply type
H07RN-F with plug and cable section equal to or
greater than the value defined in table 1 in paragraph
14.2.
When extension cables are used, make sure the cable
wires are of adequate size to avoid voltage drops.
