3.2 PUMP MEDIUM
Ego 2 (T) slim circulation pumps are designed to circulate the fluids in central heating, ventilation and air
conditioning systems. The Ego B easy version, with a bronze body, it is suitable for use in sanitary systems.
These pumps differ from standard fixed speed circulation pumps by allowing for constantly regulated pump
operation based on the actual demand of the system. This feature offers considerable energy savings, as well as
reducing noise. Before installing the pump, make sure that the water in the system is treated in compliance
with the UNI 8065 standard relating to the chemical - physical parameters of the water in thermal systems for
civil use. In the absence of this, it is necessary to carry out a washing of the system with suitable products with
neutral PH then rinsing thoroughly. Exclusively in central heating, ventilation and air conditioning systems, and
NOT in sanitary facilities, add a protective product that is sure to be effective (Builcert certified) to guarantee
the absence of corrosive phenomena on the metals of the plant. To prevent any particles of rust or magnetite
remaining in the fluid treated with protective agent, or present elsewhere in the circuit, from damaging the
pump, the circuit should be fitted with a suitable magnetic cleansing filter. This filter should have a filtration
capacity of no less than 500 microns and a magnetic field of no less than 10,000 Gauss. Wherever anti-freeze is
required, use anti-freeze fluids with specific protective agents, as set out on standard UNI 8065. In the event of
installations on pre-existing systems, these must be equipped with a magnetic cleansing filter with a filtration
capacity of no less than 500 microns and a magnetic mfield of no less than 10,000 Gauss (e.g. IDRAMAG F). This
should be installed on the circuit and sized according to the capacity of the circulation pump. For installations
on new systems, as an alternative to the system mentioned above, you can also install magnetic cleansing
filters with a magnetic capacity of no less than 1,000 Gauss (e.g. IDRAMAG or IDRAMAG FS). These should be
installed on a branch with a draining capacity of approximately 10% of the system's total flow rate. In both
cases, you must ensure that the fluid has been treated with suitable protective agents, as set out in standard
UNI 8065. Any damage caused by solid, fibrous or abrasive substances that cannot be attributed to a defect in
the original product, will INVALIDATE THE WARRANTY.
