ORIGINAL OPERATING INSTRUCTIONS
Safety
Read these instructions carefully before
installing or using the device.
The assembler and final user must carefully com-
ply with all applicable standards and laws, inclu-
ding local regulations. The manufacturer declines
any liability in the event of damage due to impro-
per use or use under conditions other than those
indicated on the serial plate and in these instruc-
tions. The device has been built in conformity with
the current European Community laws.
Symbol used:
This symbol indicates high voltage
hazard. It draws attention to
components or procedures that could
represent a potential danger to the
health and welfare of the operator.
This symbol is used to draw the
operator's attention to situations of
potential danger for people or for
operations that could cause damage to
the product.
Example plate pump
1. Operating conditions
- Energy saving circulating pumps (with inverter)
for heating and conditioning systems.
- For clean liquids without abrasives, non-
explosive, non-aggressive for the pump
materials.
- Maximum glycol quantity: 20%.
- Liquid temperature from -10 °C to +110 °C.
- Ambient temperature from 0 °C to +40 °C.
- Storage: -20°C/+70 °C max. relative humidity
95% at 40 °C.
- Maximum permissible working pressure: 6/10 bar.
- Minimum suction pressure: - 0,5 bar at 50 °C.
- 0,8 bar at 80 °C.
- 1,4 bar at 110 °C.
- Sound pressure ≤ 54 dB (A).
The pump must not be used for:
- handling of drinking water or for sanitary
applications;
- pumping of explosive liquids;
- pumping of liquids aggressive for the pump
materials.
2. Installation
Installation must be carried out by trained
personnel and in accordance with local
regulations.
Due to the weight of the product we
recommend the use of handling equip-
ments suitable for the weight of the pro-
duct (eg lifting straps or chains).
Ensure the inside of pipes are clean before
connection.
Mount pump in an easily accessible position for
ease of inspection, dismantling, checking for free
rotation of the shaft and for draining the air from
the pump.
To avoid draining and refilling of the whole pipe
system when dismantling the pump, it is
recommended to provide valves on the suction and
delivery sides.
The pump must be installed with the shaft axis
horizontal (
fig. 1 ).
In order to obtain a correct terminal box position,
the motor housing must be turned once the
screws have been loosened
(fig. 2) . Change the
terminal box positions as shown (fig. 3) .
ATTENTION: Take care not to damage the
casing gasket.
ATTENTION: The pump is equipped with
systems to drain the condensate water, in case
of insulation of the pump casing check that the
drain holes are not blocked.
During the installation phase it is required to
follow the direction of the water flow as indicated
by the arrow on the pump casing, see (
fig. 4 ).
3. Electrical connection
Electrical connection must be carried out
only by a qualified electrician and in
accordance with local regulations.
To connect the main electric line it is
necessary to open the terminal motor cover.
Follow all safety standards.
Compare the frequency and mains voltage with
the name-plate data and connect the supply
cables to the terminals in accordance with the
appropriate diagram inside the terminal box cover
(
fig. 5 ).
Make sure all cables pass through the ferrite core
supplied as standard.
