-
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).
-
In the case of maintenance, always use a set of new gaskets.
-
The appliance is intended to be permanently connected to the water mains.
Never insulate the electronic control device.
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).
Before rotating the circulator, ensure that it has been completely
drained.
To rotate the EVOPLUS SMALL circulator, proceed as follows:
1.
Remove the 4 fixing screws of the circulator head.
2.
Rotate the motor casing with the electronic control device through 90 degrees
clockwise or counterclockwise, as necessary.
3.
Reassemble and tighten the 4 screws that fix the circulator head.
The electronic control device must always remain in vertical position!

5.3.
Non-return valve
If the system is equipped with a non-return valve, ensure that the minimum pressure of
the circulator is always higher than the valve closing pressure.
6.
ELECTRICAL CONNECTIONS
The electrical connections must be made by expert, qualified personnel.
-
The circulator does not require any external motor protection.
-
Ensure that the supply voltage and frequency are the same as the values
indicated on the electrical data plate of the circulator.
6.1.
Power supply connection
After having wired the power supply cable as shown in Figure 3, connect it to the board
as shown in Figure 4.
Before supplying power to the circulator, ensure that the cover of the EVOPLUS
SMALL control panel is perfectly closed!
7.
START
All the starting operations must be performed with the cover of the
EVOPLUS SMALL control panel closed!
Start the system only when all the electrical and hydraulic
connections have been completed.
Avoid running the circulator when there is no water in the system.
As well as being at a high temperature and pressure, the fluid in the
system may also be in the form of steam. DANGER OF SCALDING!
It is dangerous to touch the circulator. DANGER OF SCALDING!
Once all the electrical and hydraulic connections have been made, fill the system with
water and if necessary with glycol (for the maximum glycol percentage see par. 2) and
feed the system.
Once the system has been started it is possible to modify the operating modes to adapt
better to the plant requirements (see par.10).
