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 electri -
cal 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 dangerous -
ly 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 as -
sistance 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 sub-
stances and solid particles or fibres, 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 SMALL circulators respect standard EN 61800-3, in the C2 category, for elec-
tromagnetic compatibility.
- Electromagnetic emissions - Industrial environment (in some cases restrictive
measures may be requested).
-
Conducted emissions - Industrial environment (in some cases restrictive meas-
ures may be requested).
4. MANAGEMENT
4.1 Storage
All the circulators must be stored in a dry covered place, with possibly constant air hu-
midity, 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).
4.3Weight
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
SMALL circulator are the same as those of the power mains.
5.1 Circular Installation and Maintenance
Always install the EVOPLUS SMALL 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 deliv-
ery 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 cir-
culating 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 con-
densate 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 im -
purities present in the system (particles of sand, particles of iron and sludge).
-
In the case of maintenance, always use a set of new gaskets.
