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

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.
