Installation: On the pump outlet (in vertical position)
Dry running protection: Yes
Expansion vessel/tank: recommended (min.20% max flow of the pump)

Why should you add the expansion vassel to the frequency inverter drive system?

The basic plant does not require the use of a compensation tank/vassel. But if you want to maximize the energy consumption and the duration of the electric pump, it's necessary to add a tank. In fact, by using a water tank, the continuous and repeated starts of the electric pump (due to small withdrawals and/or water leaks in the water system) are avoided; Decreasing the start/stop of the electric pump:

1) Decreases energy consumption;

2) Extends the life of the electric pump.

How to connect this frequency inverter drive to the submersible pump?

Attention: the power value (maximum power load) is indicative. For a correct match with the electric pump, it is essential to verify that the amps absorbed by the electric pump do not exceed the amps allowed by the inverter.

AQUONTROLLER WATER-COOLED VARIABLE FREQUENCY DRIVE

The AQUONTROLLER is designed for maintaining constant. It is very efficient and easy to install.

pressure independent in domestic application & gardening. It is characterized by the dry running protection. Smooth operation and soft starting ensure silent running and an extended electric pump life.

Energy savings are the result of the precise speed control of the inverter system.

Electrical Protection:

max. current absorbed, under- and overvoltage, short circuit between phase/ground or phase/phase, over temperature.
