DownloadWhat is the circulator's supply voltage?
The circulator’s supply voltage is 230V
What is the correct position and installation for circulators and in-line pumps?
Please check the pictograms in the instruction manual.
What wattage can be used for star connections?
Above 7.5 kW, we suggest to use this kind of start-up in order to limit very high inrush currents.
What percentage of glycol can be used in the system when the circulator is used for cooling?
The maximum amount of glycol that can be used is 20%.
How do I check the in-line pump's direction of rotation?
The in-line pump’s direction of rotation has to be checked every time a new installation is carried out.
We suggest to follow the steps given below:
- tilt the pump on its side or safely keep it suspended,
- start the pump for a moment
- check the impeller’s direction of rotation or the kickback’s direction.
The correct direction of rotation is clockwise.
If it’s not, reverse the phases of the pump’s motor.
Can I change the circulator’s settings?
If the circulator has a display, its functions can be changed according to the system’s requirements.
