Dimensions

Con guration

Settable parameters:

- Running pressure.

When the pressure in the

system falls below the Pm,

PRESFLO

starts-up the pump.

The Pm should always be

higher by at least 0.2 – 0.3

bar of the pressure genera-

ted by the column of water

overlooking PRESFLO

The Pm value can be carried

in the eld between 1 bar and

5 bar.

- Maximum current

allowed.

PRESFLO

is tted with a cur-

rent sensor, which continually

detects the absorption of the

pump. If the current remains

above the set Imax value for

a signi cant period of time,

PRESFLO

stops the pump to

protect it from damages (LOCK

condition for OVERCURRENT).

PRESFLO

nevertheless allows

, it again signals an

the Imax to be exceeded for

short periods during the pump

start-up phase.

For correct functioning,

the Imax should be set at

a value higher by approx.

10 – 20% to the maximum

absorption of the pump

(normally indicated on the

rating plate of the motor).

If this rating value is not known,

it s better to leave the standard

Imax value (16A) to avoid that

the pump stops also in normal

absorption conditions.

The Imax value may be varied

in the eld between 4A and

16A.

Disposal

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.
