SETTINGS

The ISI series softener can rapidly and easily be set,

thanks to three buttons that control time (C), salt

quantity

(D)

and

the

time

interval

between

regeneration cycles (E).

During normal operation, the current time is displayed;

conversely, during regeneration cycles, only two

running lines are visible. By pressing button (A), the

actual regeneration step under way is displayed.

INSTALLATION INSTRUCTIONS:

We suggest installing the equipment:

A-NON-RETURN VALVE

B-OUTLET TAP

C-BY-PASS TAP

D-INLET TAP

E-OVERFLOW PIPE

F-UNLOADING PIPE

Install on the water outlet a check valve (A)

(DVGW, DIN 1988 T2) to protect the water

softener from a reverse flow of hot water that could

cause damage.
