01. Read the manual carefully before installation.
02. In case of damage caused to things and/or
people due to lack of respect for installation
and use precautions, the manufacturer cannot
be held responsible.
03. For installation and use, comply with current
regulations safety standards.
04. The user must ensure that the installation
and maintenance is carried out by personnel
qualied and informed about the present
instructions.
05. The circulator must not be installed in humid
environments or wherever it may be subject to
water splashes.
06. To facilitate maintenance, it would be
appropriate to place a ball valve with union
connection at the inlet and outlet from the
circulator.
07. Electricity must be cut off during the
installation and maintenance of the circulator.
08. The P.064 series is not for circulating
domestic hot water.
09. Using the circulator with water rich in calcium
may cause blockage impeller.
10. Do not start the circulator when there is no
liquid in the system.
11. Before removing the circulator it is necessary
unload the relative section of the system in as
much as the presence of water inside is under
pressure and high temperature could cause
damage to people and/or things.
12. During the summer period or when the
room temperature is high, pay attention
to ventilation to avoid condensation and
consequent electrical failure.
13. During the winter when the temperature is
≤ 0°C, if the system is not operational, the
relative section of the plant should be emptied
thus avoiding that the frost cracks the body of
the pump.
14. If the pump is not used for a long time
period, close the shut-off valves delivery
and outlet pipes of the pump and remove
the electrical feed to the same.
15. If the cable is damaged, contact the
maintenance supplier to have it replaced
together with the connector.
16. If we are in the presence of the engine
abnormally overheated, cut off the
power immediately then close the shut-
off valves.
17. If the fault cannot be found and resolved
as instructed cut off the electrical supply,
close the valves of interception and
contact maintenance or service center.
18. Liquid under high pressure and high
temperature it will ow out if the set of
screws are removed: be careful that the
liquid does not cause injury or damage.
19. The product must be installed outside of
the reach of children.
20. The product must be installed in a
dry,cool and ventilated environment.

solid particles, fibers or mineral oil; the pump should not be used for conveying
flammable liquid such as vegetable oil and gasoline absolutely. If the circulating
pump is used for the case of high viscosity, the pump performance will reduce,
therefore, when selecting a pump, the viscosity of liquid must be considered.
4.1 Installation
· Install P.064 series circulating pump, arrows on the pump housing indicate the
direction of liquid flowing through the pump body.
· When the pump is installed on the pipeline, its inlet and outlet must be installed
with two leather packings provided.
· During installation, the pump shaft must be in the horizontal position.

It must be fluid, clean, non-corrosive and non-explosive, without particles or fibers or mineral oils; the pump
must be used for the flow / transport of inflammable liquid such as vegetable oil or diesel. If the circulation
pump is used with a highly viscous liquid, the yield will be lower, therefore when choosing the pump, keep
in mind or into into account the viscosity of the liquid.

Diverter valve:
The function of the diverter valve is to ensure that when all heating valves are closed, the flow from
the boiler is diverted into the return, ensuring a minimum flow through the pump.
Components:
•Diverter valve
•Flow meter. L position
Minimum ow must be ensured even when all valves are closed.
The programming of the pump depends on the type of diverter valve inserted.
Ex diverter valves manually opened or thermostatic diverter valves.
9.1 Use of bypass valve
8.A bypass valve system is fitted between the
inlet pipeline and return pipeline
8.1 Use of bypass valve
Bypass valve
The role of bypass valve is: when all the valves in the floor heating circuit or
the temperature control valve of radiator are closed, it can be ensured that
the heat from the boiler will be assigned.
System components:
·Bypass valve
·Flowmeter, position L.
The minimum flow must be ensured when all valves are closed.
Water pump settings depend on the type of bypass valve it equipped with,
i.e. manually-operated bypass valve or temperature-controlled bypass
valve.

Once night mode is set, the P.064 series pump will automatically alternate between normal and night mode. Switching of
the P.064 series pump between normal mode and night mode depends on the temperature of the system delivery pipe.
When the temperature drop of the system inlet pipeline within two hours is more than 10 ~ 15°C, the pump of the P.064
series will automatically switch to night mode. The temperature drop must be at least 0.1°C/min. When the system pipe
temperature rises about 10°C, it will switch to normal mode.

Follow these steps:
1/ When you adjust the diverter valve, the water pump should be in mod. HS1 (constant speed 1) The minimum system
flow (Q min) must always be ensured. See valve supplier manual diverter.
2/ When the diverter valve has been adjusted, program the water pump by referring to section 11.1 pump programming.
Follow these steps:
1/ When you adjust the diverter valve, the water pump should be in mod. HS1 (constant speed 1) The minimum system
ow (Q min) must always be ensured. See valve supplier manual diverter
2/ When the diverter valve has been adjusted, program the pump in constant pressure mode. For the relationship
between pump schedule and performance curve, see section 11.1
Before starting the pump make sure that the system is full of liquid, the air is out and the pressure is inlet reaches the
minimum pressure required (see chap.3)
The P.064 series pump has the function of automatic gas discharge (vent). It is not necessary to discharge the gas before
starting. The gas in the pump will cause noise. The noise will disappear after operating for a few minutes. Set the pump
in HS3 mode and in short time, depending on the size and structure of the system, the gas will be discharged. After the
gas purge, that is after the noise disappears, set the pump according to the recommended instructions. Please refer to

The "Auto-adapt" function will automatically check the pump performance
within the specified range
• Adjust the performance of the water pump according to the system size
• Adjusts pump performance according to load change
BL1/BL2 Proportional pressure
The duty point of the pump will move up and down on the curve proportional
pressure according to system flow needs, when the flow demand decreases,
the pressure supplied by the pump decreases while increases when the flow
demand increases
HD1/HD2 Constant curve pressure
The duty point of the pump will move back and forth on the constant pressure
curve according to flow rate requirements of the plant. The pressure supplied
by the pump remains constant
HS1/HS2/HS3 Constant speed
Curve at constant speed. In HS mode (1-3), the pump is set to operate at
constant speed in all conditions of work. Set the pump in HS3 mode and in a
short time any gases in the pump will be vented
Night mode Operation at minimum performance and consumption.
