During installation, starting and maintenance it is suggested
to the authorized operators to consider the use of individual
protection devices suitable for described activities.
During ordinary and extraordinary maintenance interventions,
safety gloves are required.

Signal individual protection device HAND PROTECTION
(gloves for protection against chemical, thermal and
mechanical risks).

5. TRANSPORTATION AND HANDLING

The product is packed to maintain the content intact.
During transportation avoid to stack excessive weights.
Ensure that during the transportation the box cannot move.

It is not necessary to use any special vehicle to transport the
packaged device.
The transport vehicles must comply, for the weight and
dimensions, with the chosen product (see technical catalogue
dimensions and weights).

5.1. HANDLING

Handle with care, the packages must not receive impacts.
Avoid to impact onto the package materials that could damage
the pump.
If the weight exceeds 55 lbs the package must be handled by two
person at the same time.

6. INSTALLATION

6.1. DIMENSIONS

For the dimensions of the device (see technical catalog).

6.2. AMBIENT REQUIREMENTS AND INSTALLATION SITE DIMEN­SIONS

The customer has to prepare the installation site in order to
guarantee the right installation and in order to fulfill the device
requirements (electrical supply, etc.).
The place where the device will be installed must fulfill the
requirements in the paragraph 3.2.
It’s absolutely forbidden to install the machine in an environment
with potentially explosive atmosphere.

6.3. UNPACKING

Inspect the device in order to check any damages which

i

may have occurred during transportation.

Package material, once removed, must be discarded/recycled
according to local laws of the destination country.

6.4. INSTALLATION

See installation examples, par. 13 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, to allow
for checking of shaft rota-tion, for filling and draining the pump
and to allow for collection of the liquid to be removed (especially
for draining liquids which are harmful or have to be removed at
temperatures higher than 140 °F).

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 (par. 13 fig. 3).

Tighten the pipes or union coupling to the extent sufficient to
ensure a tight seal.
Excessive torque may cause damage to the pump.
When the pipe or union coupling is mounted, keep the pump
casing connection blocked with a second wrench, making sure
the connection is not deformed by excessive tightening.
The pipe diameters must not be smaller than the pump
connections.

6.4.2. SUCTION PIPE

If the suction pipe is longer than 33 ft, use an internal pipe
diameter larger than the pump suction connection.
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,
par. 13. 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 avoid the hose narrowing due to suction vacuum.
With the liquid level on the suction side above the pump (inflow
under positive suction head, par. 13. fig.1) 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 49 ft 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 qual-

ified electrician in accordance with local regulations.
