5.14 - Protection against cavitation (option 116)
To ensure the durability of the pumps in the integrated
hydronic modules, the control algorithm of the 61WG/30WG/
30WGA units incorporates anti-cavitation protection.
It is therefore necessary to ensure a minimum pump entering
pressure of 60 kPa (0.6 bar) during operation and at shut-down.
A pressure below 60 kPa will prohibit unit start-up or cause
an alarm with the unit shutting down.
In order to obtain sufcient pressure, it is recommended:
• to pressurise the hydronic circuit between 100 kPa and
300 kPa (1 and 3 bar) maximum on the suction side of
the pump,
• to clean the hydronic circuit before charging water,
• to regularly clean the screen lter.
