2. GENERAL
Read this documentation carefully before installation.
Installation, electrical connection and commissioning must be carried out
by specialised personnel, in compliance with the general and local safety
regulations in force in the country in which the product is installed. Failure
to respect these instructions not only causes risk to personal safety and
damage to the equipment, but invalidates every right to assistance under
guarantee.
The appliance is not intended to be used by persons (including children)
with reduced physical, sensory or mental capacities, or who lack experi-
ence or knowledge, unless, through the mediation of a person respon-

tions on the use of the appliance. Children must be supervised to ensure
that they do not play with the appliance.
Ensure that the product has not suffered any damage during
transport or storage. Check that the outer casing is unbroken
and in excellent conditions.
2.1 Safety
Use is allowed only if the electric system is in possession of safety pre-
cautions in accordance with the regulations in force in the country where
the product is installed.
2.2 Responsibility
The Manufacturer does not vouch for correct operation of the machine or
answer for any damage that it may cause if it has been tampered with,

2.3 Particular warnings
Always switch off the mains power supply before working on
the electrical or mechanical part of the system. Wait for the war-
ning lights on the control panel to go out before opening the
appliance. The capacitor of the direct current intermediate circuit
remains charged with dangerously high voltage even after the
mains power has been turned off.

cable standards).
Mains terminals and motor terminals may still have dangerous
voltage when the motor is stopped.

3. PUMPED LIQUIDS
The machine has been designed and made for pumping water, free from

Kg/m³, a kinematic viscosity of 1mm²/s and non chemically aggressive
liquids. It is possible to use ethylene glycol in a percentage of no more
than 30%.
4. APPLICATIONS
EVOPLUS series circulators allow integrated adjustment of the differ-
ential pressure which enables the circulator performance to be adapted
to the actual requirements of the system. This determines considerable
energy saving, a greater possibility of control of the system, and reduced
noise.
EVOPLUS circulators are designed for the circulation of:
- water in heating and conditioning systems.
- water in industrial water circuits.
- domestic water only for the versions with bronze pump body.
EVOPLUS circulators are self-protected against:
-Overloads
-Lack of phase
-Excess temperature
- Over-voltage and under-voltage

5.1 Electromagnetic Compatibility (EMC)
EVOPLUS circulators respect standard EN 61800-3, in the C2 category,
for electromagnetic compatibility.
- Electromagnetic emissions - Industrial environment (in some cases
restrictive measures may be requested).
- Conducted emissions - Industrial environment (in some cases re-
strictive measures may be requested).
6. MANAGEMENT
6.1 Storage
All the circulators must be stored in a dry covered place, with possibly
constant air humidity, free from vibrations and dust. They are supplied in
their original pack in which they must remain until the time of installation.
If this is not the case, accurately close the suction and delivery mouth.
6.2 Transport
Avoid subjecting the products to needless impacts and collisions. To lift
and transport the circulator use lifting devices with the aid of the pallet
supplied with it (if contemplated).
6.3 Weight
The adhesive plate on the packaging indicates the total weight of the
circulator.
7. INSTALLATION
Carefully follow the advice in this chapter to carry out correct electrical,
hydraulic and mechanical installation.
Always switch off the mains power supply before working on
the electrical or mechanical part of the system. Wait for the war-
ning lights on the control panel to go out before opening the ap-
pliance. The capacitor of the direct current intermediate circuit
remains charged with dangerously high voltage even after the
mains power has been turned off.

pliance must be earthed (IEC 536 class 1, NEC and other appli-
cable standards).
Ensure that the voltage and frequency on the data plate of the
EVOPLUS circulator are the same as those of the power mains.
7.1 Circular Installation and Maintenance
Always install the EVOPLUS circulator with the motor shaft in a
horizontal position.Install the electronic control device in a verti-
cal position (see Figure 1)
- The circulator may be installed in heating and conditioning systems
on either the delivery pipe or the return pipe; the arrow marked on the
SXPSERG\LQGLFDWHVWKHGLUHFWLRQRIÀRZ
- Install the circulator as far as possible above the minimum boiler level
and as far as possible from bends, elbows and junction boxes.
- To facilitate control and maintenance operations, install an interception
valve both on the suction pipe and on the delivery pipe.

If the motor assembly has been removed from its seat, pay the greatest
attention during assembly, taking care to insert the impeller completely

has been correctly assembled, the motor assembly rests completely on
the pump body.
Incorrect assembly may damage the impeller, causing a typical
rubbing noise when the circulator starts.
The electronic control device must always remain in vertical po-
sition!

ter at 80°C. Then drain the system completely to eliminate any harmful
substance that may have got into circulation.
- Assemble in such a way as to avoid dripping on the motor and on the
electronic control device during both installation and maintenance.
- Avoid mixing additives derived from hydrocarbons and aromatic prod-
ucts with the circulating water. It is recommended that the addition of
antifreeze, where necessary, should not exceed 30%.
- In the event of heat insulation use the special kit (if provided) and en-
sure that the condensate draining holes in the motor casing are not
closed or partly blocked.

separate and collect any impurities present in the system (particles of
sand, particles of iron and sludge)
Never insulate the electronic control device.
- In the case of maintenance, always use a set of new gaskets.
7.2 Rotation of the Motor Heads
If the circulator is installed on pipes in a horizontal position, it will be nec-
essary to rotate the motor with the respective electronic device through
90 degrees in order to maintain the grade of IP protection and to allow
the user a more convenient interaction with the graphic interface (see
Figure 2).
Before rotating the circulator, ensure that it has been completely
drained.
Should it be necessary to rotate the motor heads, follow the instructions
below with care to ensure correct installation:
