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.

PUMPED LIQUIDS

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.
- Conducted emissions - Industrial environment (in some cases restrictive measures may be
requested).
4. MANAGEMENT
4.1. Storage
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).
The adhesive plate on the packaging indicates the total weight of the circulator.
³ , a kinematic viscosity of 1mm ² /s and non chemically
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.
- 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 products 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 ensure that the condensate
draining holes in the motor casing are not closed or partly blocked.
- To guarantee maximum efficiency of the system and long life of the circulator it is recommended
to use magnetic sludge-removing filters to 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.
5.2.

Rotation of the Motor Heads

If the circulator is installed on pipes in a horizontal position, it will be necessary 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 2-3).
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:
