4.3 Unpacking the Product information for installers
Use suitable equipment. Observe all the accident prevention regulations in force. Lift and handle the product carefully, using suitable
lifting equipment.
When you receive the electric pump, check the outside of the package for any signs of damage. If the product appears to be damaged, notify our distributor
within 8 days from the delivery date.
4.3.1 Disposal of Packing Materials
If you cannot utilize the packing container for other purposes, dispose of it according to the waste disposal regulations locally in force.
4.4 Handling the Product
Lift and handle the product carefully, using suitable lifting equipment. Observe all the accident prevention regulations.
The product must be securely harnessed for lifting and handling.
5. Installation information for installers
The installation operations must be carried out by qualified and experienced personnel.
Use suitable equipment and protections. Observe the accident prevention regulations in force.
Carefully read the installation limits specified in section 3.1.7
Always refer to the local and/or national regulations, legislation and codes in force relating to the selection of the installation site and the water and power con-
nections.
5.1.1 Position
Make sure that no obstructions or obstacles hinder the normal flow of the cooling air delivered by the motor fan. Provide adequate clearance around the
pump for the maintenance operations. Whenever possible, raise the pump slightly from the level of the floor. Carefully observe the diagrams provided in sec-
tion 10.8.
5.1.2 Anchoring
Please refer to the pump manual.
5.1.3 Selecting the Suction and Delivery Pipes
Use pipes suited to the pump’s maximum working pressure.
In case of an open circuit, make sure that the diameter of the suction pipe is suited to the installation conditions and that it is not smaller than the diameter
of the suction port. Refer to the illustrations in section 3.1.4.
Refer to the relevant electric pump manual.
5.1.4 Selecting the Foot Valve
Install a foot valve at the end of the suction pipe if the level of the liquid source is lower than the pump’s. Refer to the instructions provided in section 3.1.4.
Refer to the relevant electric pump manual.
5.1.5 Selecting the Electric Control Panel
The motors must be suitably protected against overload and short circuits.
Make sure that the panel’s electric ratings match those of the electric pump. Improper combinations may cause problems and fail to
guarantee the protection of the electric motor.
Avoid the possibility of dry running, i.e. the pump must not run without water inside it. Make sure that the electric panel is equipped with a
dry running protection system to which you must connect a pressure switch or float switch or sensors or other suitable device.
If you use thermal relays, we recommend those that are sensitive to phase failure.
Make sure that the control panel and any control devices are suitable for installation in the selected location (Directive 1999/92/EC –
ATEX 137 regarding the safety and health of personnel who may be exposed to the risk of explosive atmospheres)
6. Start-up information for installers
6.1 Water Connection
The water connections must be made by a qualified installation technician in compliance with the regulations in force.
In case of connection to the water system, the regulations issued by the competent authorities (municipal, public utility company,…)
must be observed. These regulations often require the installation of a backflow prevention device, such as a disconnector or check
valve or disconnection tank.
The suction pipe must be perfectly sealed and watertight. If the pump/electric pump is installed near dwellings, suitable pipes or flexible unions should be pro-
vided to prevent the transmission of vibrations from the pump to the pipes. Install on-off valves on the suction and delivery sides to avoid having to drain the
system before maintenance, repair or pump replacement operations can be performed. Whenever necessary, provide a by-pass circuit to prevent the
overheating of the water inside the pump.
Refer to the instructions provided in section 3.1.4.
