Stainless steel pumps in domestic hot-water
systems:
In domestic hot-water systems, we
recommend that you keep the liquid
temperature below 65 °C to eliminate the
risk of lime precipitation.
Ambient temperatures below 0 °C
require the following conditions:

• The pump runs continuously and
does not stop.
• For twin-head pumps cascade
operation every 24 hours is
mandatory.
