A,AS Rev13 - Operating Instructions
4.2. Safety devices
The device has an external case that prevents any
contact with internal parts.
4.3. Residual risks
The appliance, designed for use, when used in-
line with the design and safety rules, doesn’t have
residual risks.
4.4. Information and Safety signals
For this kind of product there will not be any signals
on the product.
4.5. Individual protection devices
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, where it is required to remove the
filter, 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 25 Kg 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
catalogue).
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
i
Inspect the device in order to check any
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.
Provide enough clearance around the unit for
motor ventilation and for filling and draining the
pump.
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. 12.3 fig. 1).
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
The suction pipe must be perfectly airtight.
If operating with flexible hoses use a semi rigid
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.
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.
6.4.4. Alignment of pump-motor unit AS
The pump-motor units positioned on a baseplate
and with a flexible coupling are aligned before
leaving the factory.
The pump and motor assembly can lose alignment
during shipping. Final alignment must be
accomplished in the field.
After installation is completed with tightening
of anchor bolts and connection of pipes,
alignment of the coupling must be
double-checked before starting the
pump.
