1. Introduction of the 4HS submersible pumps range
4HS is a 4” centrifugal submersible pump for clean water composed by:
three phase pump with wet rotor and canned type resin filled stator.
Built-in inverter on board.
Multi stage pump entirely made of AISI 304 stainless steel.
Pump driving made by inverter allows:
Modify the pump speed. In this way the pump is operated only and when needed thus avoiding unnecessary
waste of energy and granting longer system life.
Implement the soft start and the soft stop to increase the system life and reducing the current peaks.
Protect the pump from overloading and dry running , overvoltage, undervoltage and possible abnormal
conditions.
4HS is used on residential and industrial sectors for water pressurized systems, granting:
Energy saving.
Simplified and quick installation.
Long life reliability.
4HS MultiPower pumps can be fed both AC and DC with wide margins of operating voltage (90-265 VAC or 90-400
VDC). This means that the same pump can be powered by photovoltaic panels, by wind or diesel generator or by
batteries. The hydraulic performance will be adjusted automatically according to the power source and the power
available.
In the application with photovoltaic panels an MPPT algorithm maximizes, for various conditions of irradiation and
temperature, the electric power obtained from the panels thus the amount of water extracted.
Pump speed is adjusted in relation to solar irradiation. When solar irradiation increases, pump will run faster thus
pumping more water. When solar irradiation decreases (clouds moving or different hours of the day) pump will
reduce its frequency and so delivery but it continues pumping till solar irradiation reaches the minimum value
necessary for working.
4HS MultiPower pumps can be installed with or without the surface control module.
When installed, the CM MP monitors and records:
Running hours.
Input voltage, current and power.
Alarms: dry running, overload, overvoltage.
Digital inputs make it possible to connect a float switch, a pressure switch, a start and stop signal, etc...
Running and alarm status are given by two digital outputs.
Analogical inputs can be used to connect sensors (i.e. flow meter).

2. Safety Instructions
The manufacturer strongly suggests to reading carefully 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 instruction of this manual may result fatal in dangerous electric shock.
The unit must be connected to the power supply by a switch granting the
complete visual disconnection (separation) from the line before any operation.
Disconnect the unit from the power supply before any operation.
Do not remove for any reason, the cover of the CM MP and the cable guard
without having visually disconnected the unit from the power supply and
having waited at least 5 minutes.
CM MP and pump system must be grounded properly before operation.
For the entire period the CM MP is powered a high voltage is present on the
output terminals independently if it is running or not the pump.
Do not start the pump for any reason if not completely immersed in water.
Avoid any shock or serious impact during transportation.
Check the product immediately upon delivery and check for damage and/or missing parts. In either case,
immediately notify the supplier.
Damages due to transportation, incorrect installation, or improper use of the device will null and void the warranty.
The manufacturer cannot be held responsible for any damage to people and/or property due to improper use of
its products.

3. CM MP installation
The CM MP can be easily fixed to the wall using 2 screws through the holes shown.
Then using the special inserts thus cover can be fixed firmly.
The IP55 protection degree enables the CM MP installation even in humid and dusty environments. However it is
recommended to protect the CM MP from the direct exposure to weather and sunlight.

Read carefully the Guidelines for safety before installing the device.
At the end of the installation check that no other objects are inside the CM MP
or deposited on the electronic board.
It is recommended to tighten all 4 screws with washers of the cover before
powering the device. Otherwise, you may fail to connect to ground the cover
with a risk of electric shock or even death.
