Warranty
The manufacturer guarantees this product for a period of 24 months as of the date of sale; the
device must be returned together with this instruction manual, with the date of installation and
programmed parameters noted in the last page of this document.
The guarantee will be rendered null and void if the device is tampered with, disassembled, or
damaged due to causes aributable to incorrect use and/or improper installation, if it is used for
purposes other than as specified, if it is installed in unsuitable environmental conditions or if it is
connected to an electrical installation that does not comply with current standards.
The manufacturer declines all liability in the event of damage to objects and/or physical injury
caused by failure to install the necessary electrical safety devices up line of the device, or due to an
unprofessional installation.
Installation and maintenance of this device must be performed by specialist personnel, able to fully
understand the contents of this instruction manual.
All operations performed with the device cover removed must be performed with the power mains
disconnected.
As there are no concrete reasons for removal of the electronic board, take into account that some
of the board parts remain live for a few minutes also aer disconnecting the device from the
mains.
The manufacturer declines all liability in the event of damage to objects and/or physical injury
caused by failure of an internal protection device, with the exception of the refund of the device, if
still covered by the guarantee. This device complies with the directive ROHS 2002/95/EC.
Description
Flowcon VSD - B Inverter is an electronic control device for single phase electric pumps which
enables automatic start-up and shutdown of the pump, protecting it in the event of adverse
operating conditions (failure of water supply, motor overload, risk of ice).
The Flowcon VSD - B Inverter can operate on various systems:
- with a single electric pump,
- in a twin pump system in which the two alternate automatically
Flowcon VSD - B Inverter inverter is programmable to operate on the basis of two dierent
principles:
- mode P+F (pressure + flow) = in this mode, the pump is started up following a fall in pressure,
when the minimum set threshold is reached (Pmin); the pump operates until the water supply runs
out and there is zero flow through the device. In this condition the resulting pressure in the system
will correspond to the maximum pump head.
- mode P+P (pressure + pressure) = in this mode the pump operating mode is controlled within
two pressure levels (Pmin e Pmax); when the lower pressure threshold is reached (Pmin) the
pump is started up, while it is stopped when the upper pressure threshold (Pmax) is reached.
In this configuration, the use of an expansion vessel is essential, sized according to the system
requirements and type of pump.
