ATTENTION
The maximum pressure
produced by the pump must
be at least 1-1.5 bar higher
than the start-up pressure
( Pm ) . If the pressure
produced by the pump is too
low, PRESFLO
®
will stop the
pump and indicate a ‘dry
running’ error message.
When disposing of any PRESFLO
®
parts, adhere to the
relevant laws and regulations in force in the country in
which the equipment is being used. Do not dispose of
any polluting parts in the environment.
ATTENTION
The pressure applied by the
water column above
PRESFLO
®
must not exceed
that of the pump start-up
pressure ( Pm ).
If, for example, PRESFLO
®
is
installed at a height 20
metres below that of the
highest tap in the system, the
pressure detected by
PRESFLO
®
will be
approximately 2 bar.
A model with Pm = 2.2 bar
should, therefore, be installed
in order to guarantee that the
pump is started when a tap
is turned on.

Electrical connections
ATTENTION
The cable bushings and circuit
board cover must be properly
assembled and secured in order
to guarantee IP 65 grade protection
of the electrical components.
First start-up
Priming the pump
For instructions on how to prime (fill) the pump, see the pump
manual.
ATTENTION
PRESFLO
®
is fitted with a check valve: do not use the PRESFLO
®
’s
outlet to fill the pump for priming.
Switching the pump on
The red (Power) LED lights up; PRESFLO
®
instantly
detects that there is no pressure within the system
and starts the pump (the green ‘Status’ LED lights up).
If, within 15 seconds of starting up, PRESFLO
®
does
not detect the correct priming of the pump, it stops
the pump and indicates a ‘dry running’ error message.
ATTENTION
When the pump is started for
the first time, it may have to be
run for longer in order to
complete the priming procedure.
Press the START/STOP
button
to restart the pump and
complete the priming procedure.
