the pump body.
Incorrect assembly may damage the impeller, causing a typical
rubbing noise when the circulator starts.
The electronic control device must always remain in vertical po-
sition!

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)
Never insulate the electronic control device.
- In the case of maintenance, always use a set of new gaskets.
7.2 Rotation of the Motor Heads
If the circulator is installed on pipes in a horizontal position, it will be nec-
essary 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.
Should it be necessary to rotate the motor heads, follow the instructions
below with care to ensure correct installation:
