3.1.4 Maximum system pressure
Make sure that the system in which the pump is instal-
led is designed for the maximum pump pressure.
When installing a non-return valve in the plumbing sys-
tem, make sure that the system has an expansion tank
at the water heater and that the pressure-relief valve in
the water heater is plumbed to a drain. Carry out the in-
stallation in accordance with local regulations.
The maximum inlet pressure depends on the head at the
actual duty point. The sum of the inlet pressure and the
head must not exceed the maximum system pressure.
W
e recommend installing a pressure-relief valve to protect
the pump so that the outlet pressure does not exceed the
maximum system pressure.
