6.3. Unpacking
Inspect the device in order to check any
i
damages which may have occurred during
transportation.
Package material, once removed, must be discarded/
recycled according to local laws of the destination
country.
6.4. Installation
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,
to allow for checking of shaft rotation.
6.4.1. Pipes
Ensure the insides of pipes are clean and unobstructed
before connection.
ATTENTION: The pipes connected to the pump
should be secured to rest clamps so that they
do not transmit stress, strain or vibrations to the
pump.
Tighten the pipes or union coupling to the extent
sufficient to ensure a tight seal.
Excessive torque 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 a pump located above the water level (suction
lift operation) fit a foot valve with strainer which must
always remain immersed or a check valve on the
suction connection.
If operating with flexible hoses use a reinforced spiral
suction hose, in order to avoid the hose narrowing due
to suction vacuum.
With the liquid level on the suction side above the
pump (inflow under positive suction head) fit an inlet
gate valve.
For suction from a storage tank fit an anti-backflow
valve. Follow local specifications if increasing network
pressure.
Install a strainer 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. Install a pressure gauge.
With a geodetic head at outlet over 15 m fit a check
valve between the pump and the gate valve in order to
protect the pump from water hammering.
6.5. Electrical connection
OFF
Electrical connection must be carried out only
by a qualified electrician in accordance with
local regulations.
Follow all safety standards.
The unit must be properly earthed (grounded).
Connect the earthing (grounding) conductor to the
terminal with the marking.
Compare the frequency and mains voltage with the
