ELECTRICAL INSTALLATION

Electrical connection must be carried out by qualified person. Connection to electrical supply is shown
on figure:
The electrical connection of pump to the power supply (1~230V, 50 Hz) must be carried out with
suitable connecting cable (equivalent to connecting cable 3G 1mm2, H05RR-F).The supply cord shall
be connected the way it cannot come into contact with parts of enclosure due to high temperature of
the enclosure.

PUMP OPERATION

Pump can be turned on/off with five seconds press off a button on electric box. When pump is turned
off the orange light blinks.
Pump goes through calibration procedure every time it is turned on by button or by power up. This
procedure takes about 20s and is indicated with blinking green light (4 times) and then blinking blue
light (4 times). Meanwhile pump is calibrating, it is advised that all outflows are closed.
In normal operation pump is constantly detecting flow changes. If there is no flow or flow is low, pump
runs at low power, which is indicated with blue light. In case of sudden increase of flow for
approximately 100 l/h pump starts to run with high power to ensure needed pressure/flow on the
outflow. High power running is indicated with green light. When flow falls under approximately
100 l/h, pump goes back to low power running. Pump has one hour time limitation on high power
running. So, if user has a failure in the system or forgets to turn the tap off, pump will stop after an
hour and reduce power and water consumption.
Charts of the curves are located at the end of the manual.
