WARNING
Always install pumps with output of maximum pressure at least 1 bar higher than the minimum start-up pressure setting.
If the water column over the device is higher than 15m it is necessary to increase the start-up pressure.
Examples
Water column height
Start-up pressure setting
Pump must have max pressure equal or greater
than:
20m
2.5 bar
3.5 bar
25m
3 bar
4 bar
To increase the start-up pressure:
-
Connect and turn on the Hydromatic, wait until it stops.
-
Open a tap slowly and observe the pressure gauge to identify at what pressure the pump starts.
-
Turn the adjustment screw on the rear of the unit to the right.
-
Recheck the start pressure as per Step 2 until the desired pressure is achieved.
