These instructions include information necessary to assemble and use the product correctly.
Besides respecting the general safety regulations, it is necessary to observe all points specically and specially marked.
3 Indication of instructions
This manual contains information and prescriptions marked by the following symbols.
The inobservance of the safety provisions marked by the symbol “CAUTION”:
hazard” may endanger the safety of people.
The inobservance of the safety provisions marked by the symbol “CAUTION”:
electricity” may endanger the safety of people, as well as the integrity of
things.
The inobservance of the safety provisions marked by the word “CAUTION”
CAUTION
The Quick Guide contains following warning symbols.
may endanger the integrity and functionality of the equipment and of the
machines.
The circulators are not to be used to transfer ammable liquids such as
gasoline, oils, gas oil or similar liquids.
The circulators are not to be used to transfer aggressive liquids, such as acids
and sea water.
CAUTION
The removal of the screws can cause the output of hot uids under high pressure from heating system. Drain the system or close the isolating valves.
6 Indication of instructions
CAUTION
High temperature surface. Pay utmost care to prevent people from getting in
contact with the hot surfaces of the circulator.
4 Important safety and installation instructions
Prior to installation, read these installation and operating instructions. The installation and
operation should also be in accordance with national regulations and accepted codes of good
practice.
This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge, only if they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
To guard against injury, basic safety precautions should be observed, including the following:
1. Read and follow all safety instructions and all the important notices on the
appliance before installing, using and maintaining the circulator. failure to do so
may cause personal injury or damage to the circulator or installation.
2. Always disconnect electrical supply before putting on or taking off parts
and whilst the equipment is being installed, maintained or handled. Never
work with bare feet and/or with wet hands.
3. To avoid possible electric shock, special care should be taken since
water is used with electrical equipment. Carefully examine the circulator
before and after installation. Do not operate the circulator if it has a damaged
supply cord or enclosure, or if it is malfunctioning or it is dropped or damaged
in any manner. Inspect the circulator periodically. The circulator should not be
electrically supplied if there is water on parts not intended to be wet.
4. Risk of scalding.
To avoid injury before any servicing operation wait until the water has cooled
inside the circulator.
Do not touch the uid or the circulator when temperature is higher than 60°C.

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. ammable 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 corro-
sive 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 lled with
water when operating.
6. Installation
The circulator must be mounted in a stable/xed position in a dry, well
ventilated, frost-free, waterproof and protected place, with sufcient ventilation
around it. Assemble 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 disassembly 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 xed power cable which is tted 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 qualied 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.
8 Important safety and installation instructions
10. Any modication to the equipment must be prior agreed upon with and au-
thorized 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 accessories
may endanger the safety and causes the termination of the warranty. A safe
operation is assured only for the applications and conditions described in → 5
Field of application of this manual. Non-observance of the safety instructions
results in the loss of any claims to damages.
Non-observance of the safety instructions results in the loss of any claims to
damages.
The indicated limit values are binding and cannot be exceeded for any reason
whatsoever.
Keep these instructions for future reference.
