• If the pump does not turn, make sure the power cable and the modulating
signal cable are connected to the ecotronic Tech controller.
• If the pump is noisy, make sure there is no air inside the circuit otherwise
repeat the commissioning operation. If necessary, increase the system
pressure to the permissible design maximum or operate the pump speed
selector, selecting a lower one or suitable for system requirements.

Install the circulation unit on a solid wall not subject to vibration.
Make sure the place of installation and the systems to which the
equipment must be connected comply with the current regulations.
Handle the unit with suitable protection and due caution. Do not
damage existing piping when drilling the wall. Empty the parts that may contain
hot water, by activating any vents, prior to handling. reinstate all the safety and
control functions involved in work on the unit and check their operation before
recommissioning.
The circulation unit is powered. Disconnect the power before any
maintenance on the pump. Do not damage existing electrical cables
when drilling the wall. Make the electrical connections with wires of
suitable section. Protect the connection cables to prevent them from
being damaged. Use suitable electrical equipment (in particular, make sure the
power cable is intact and that the parts with rotary or reciprocating motion are
properly secured), use it correctly, do not obstruct the passages with the power
cable, and prevent possible falling from above.
