- Nel montaggio delle valvole sull’impianto rispettare il senso di
flusso delle frecce incise sul corpo.
- La valvola a due vie può essere installata sia sulla tubazione di
andata che su quella di ritorno.
- La valvola a tre o quattro vie va installata sulla tubazione di
mandata.
- La valvola va installata con manopola rivolta verso l’alto o in
posizione orizzontale, mai in posizione rovesciata.
- Nell’installazione in cassetta lasciare uno spazio di almeno 20 mm
tra comando elettrotermico e telaio per un eventuale sostituzione
o manutenzione.
- La valvola a tre vie non può essere trasformata in valvola a due vie.
- When mounting the valve onto the system the arrows indicating the
flow direction must be respected.
- The two-way valve can be installed either on the supply pipe or on
the return pipe.
- The three or four-way valve should be installed on the supply pipe.
- The valve should always be installed with the handle in the up-
right or horizontal position, it should never be in the upside-down
position.
- When the valves are installed into boxes, there must be at least
20 mm of space left between the control actuator and the frame.
This is for maintenance or replacement reasons.
- The 3-way valve should never be converted into a 2-way valve.
