Group cannot be subjected to very high temperatures, such as occur during eg. welding or soldering. It
should be installed only after the finished such work.
After assembly of the group, pressure test must be performed in order to check the tightness in the
threaded connections.
After connection water pump group to the installation make electrical connection of the pump and valve

are intact and suitably electrically isolated from human touch during operation.
Electric connection for the pump
The pump requires no external motor protection. Check that the supply voltage and frequency correspond to the values
stated on the nameplate.
The pump must not be used with an external speed control which varies the supply voltage, for example phase-cut or
pulse-cascade control.
The supplied pumps are delivered with molex 3-pin plug
and cable to moved out of the pump group casing
. Connect
power supply to the three leads L, N and PE.
The cable size to be used is 3 core 0.75mm2. The cable should be capable of withstanding a minimum
