5. Improper use
This is a circulator to be used in heating plants and for the circulation of clean
water without abrasive particles. This is not a submersible pump.

Do not use this circulator:

With liquids other than water (e.g. flammable liquids, etc.) (EN60335-2-
51);

For handling drinkable water or food related liquids;

For the circulation of domestic water;

In locations where special condition prevail, such as the presence of a
corrosive or explosive atmosphere (dust, vapor or gas) (EN60335-2-
51);

For other than intended use.
Never run the circulator dry. The circulator must be always fully filled with
water when operating.
6. Installation
The circulator must be mounted in a stable/fixed position in a dry, well
ventilated, frost-free, waterproof and protected place, with sufficient ventilation
around it. Make sure that the circulator is securely and correctly installed
before operating it and that there is enough room around it for maintenance
operations, dismantling, checking for free inspection.
The maximum ambient temperature at which the pump is to be used is 40°C
(EN60335-2-51).
To avoid circulator overheating, do not place any object on the circulator itself.
7. Electric connection
IMPORTANT: Connection to the power supply must be effected by means of a
fixed power cable which is fitted with a plug-type connection or an all-pole
isolating switch with a minimum contact opening of 3 mm.
Electrical connection must be carried out only by a qualified electrician and in
accordance with local regulations and both data on the name-plate and the
appropriate diagram inside the terminal box cover.
Follow all safety standards.
Do not connect to mains supply unless circulator is fully and correctly
assembled.
8. Supply cord must be selected following the requirements of EN60335-2-51
Chapter 25. Supply cord must be protected against any kind of mechanical
damage (cuts, abrasion, etc.). It must not touch the pipe or the pump. (EN
60335-2-51). If the insulation of the Supply cord can come in contact with parts
having a temperature exceeding 70°C the supply cord insulation must be
protected, for example, by insulating sleeving having an appropriate
temperature rating. (EN60335-2-51) .
9. Connect circulators only to a mains supply protected by a Residual Current
Device (RCD or Ground-Fault Circuit-Interrupter) with a rated residual
operating current not exceeding 30mA.
10. Any modification to the equipment must be prior agreed upon with and
authorized by the manufacturer. Original spare parts and accessories
authorized by the manufacturer are integral part contributing to the safety of the
equipment and of the machines. The use of not original components or
