2. Safety Instructions
The manufacturer strongly suggests carefully reading this operation manual before using and installing its products
Any operation (installation, maintenance and repair) must be carried out by trained, skilled, and qualified personnel.
Failure to observe and follow the instructions in this manual may result in dangerous and potentially lethal results.
Pay attention to all standard safety and accident prevention regulations.
The device must be connected to power supply via a switch to ensure the complete
disconnection from the power supply before any operation on the device itself (including visual
inspection).
Disconnect the device from the power supply before commencing any work.
Do not disassemble for any reason the device without having first disconnected the device from
the power supply and having waited at least 5 minutes.
The device and pumping system must be grounded properly before operation.
For the entire period the device is powered, high voltage is present on the output terminals of
the inverter part whether or not the pump is running.
Tightening all the screws on the cover with washers is recommended before powering the device.
Otherwise, there may be a failure to connect the cover to ground, creating the risk of electric
shock or even death.
When powering the device with both PV panels (DC) and grid or generator (AC) it is necessary to
connect only one power source (AC or DC) at a time, to switch between AC and DC power supply
through an AC / DC switch, to install protections on both the AC and DC side in accordance with
local regulations.
The pump must operate only if completely filled with water. Failure to do so may result in severe
damage to the pump itself with consequent expiry of the warranty.
The installation must be in a dry, well - ventilated place, protected from access by unauthorized
persons (including children) and from direct exposure to the sun and atmospheric agents.
The pump can contain traces of water used for the final tests of the product. Before putting into
service, it is recommended to wash with fresh water. Do not use solvents or other chemicals for
cleaning any part of the product.
In the case of long periods of inactivity, it is recommended to completely empty the pump to
avoid blocking and freezing of the hydraulic part.
Inspect the pump and the suction filter periodically (at least once a year).
During operation some parts of the pump can reach temperatures above 40 ° C (104 ° F). Avoid
contact with flammable products and always ensure proper ventilation.
The pump is designed to work only with fresh or salty water free of solid particles and fibers,
with a maximum sand content of 50 g/m3.
During operation the pump produces a strong suction that can trap people (especially children)
causing severe physical damage or even death.
To reduce these risks, it is recommended to install the pump and the system according to local
regulations and check the correct functioning of the grilles that protect the suction points.
Do not loosen, unscrew or open the filter cover for any reason while the pump is running. If the
pump is installed below the water level, close the intake valve before opening the filter cover.
Failure to comply with these recommendations can result in severe damages or even death.
Avoid any shock or significant impact during transport.
Check the product immediately upon delivery and check for damage and/or missing parts. If either occurs, immediately
notify the supplier.
Damages due to transport, incorrect installation, or improper use of the device will null and void the warranty.
Tampering or disassembly of any component will automatically void the warranty.
The manufacturer cannot be held responsible for any damages to people and/or property due to improper use of its
products.
