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 circula
-
tor:
• 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. As
-
semble the circulator only after having ended all welding and brazing works on the
hosing. Before installing the circulator, make sure that the internal part of the tubes
is clean. Install the circulator in an accessible place for future checks and disassem
-
bly procedures. Foresee enough space for inspections and disassembling.
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.
