ENGLISH
- 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.
-
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).
- In the case of maintenance, always use a set of new gaskets.
Never insulate the electronic control device.
7.2 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.
2. Rotate the motor casing with the electronic control device through
90 degrees clockwise or counterclockwise, as necessary.
3.
-
The electronic control device must always remain in vertical
position!

7.3 Non-return valve
If the system is equipped with a non-return valve, ensure that the mini-
mum pressure of the circulator is always higher than the valve closing
pressure.
