1. PARTICULAR WARNINGS
Ensure that the product has not suffered any damage during
transport or storage. Check that the outer casing is unbroken and in
excellent conditions.
Always switch off the mains power supply before working on the
electrical or mechanical part of the system. Wait for the warning 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.
Only firmly cabled mains connections are admissible. The appliance
must be earthed (IEC 536 class 1, NEC and other applicable
standards).
Mains terminals and motor terminals may still have dangerous
voltage when the motor is stopped.
If the power cable is damaged, it must be replaced by the technical
assistance service or by qualified personnel, so as to avoid any risk.
2. PUMPED LIQUIDS
The machine has been designed and made for pumping water, free from explosive
substances and solid particles or fibers, with a density of 1000 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%.
3. 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 restrictive
measures may be requested).

4. MANAGEMENT
4.1. 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.
4.2. 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).
4.3. Weight
The adhesive plate on the packaging indicates the total weight of the circulator.
5. INSTALLATION
Carefully follow the advice in this chapter to carry out correct electrical, hydraulic and
mechanical installation.
Ensure that the voltage and frequency on the data plate of the
EVOPLUS circulator are the same as those of the power mains.
5.1. Circular Installation and Maintenance
Always install the EVOPLUS circulator with the motor shaft in a
horizontal position.Install the electronic control device in a vertical
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 pump body indicates the
direction of flow.
- 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.
- Before installing the circulator, accurately flush the system with only water at 80°
C. Then drain the system completely to eliminate any harmful substance that may
have got into circulation.
