is equipped with high efciency electronically controlled circulation units. The performance data of these units to be used to
size the system is shown in the graph.

When starting up for the rst time and at least once a year,
it is advisable to check that the shaft of the circulation units
rotate.This is necessary because, especially after lengthy pe-
riods of inactivity, deposits and/or residue may stop it rotat-
ing freely.

Do not run the circulation unit without water.

If there are ow regulator devices in the low temperature
circuits (thermostatic, electrical or motorized zone valves,
etc.) it is recommended that the circulation unit is set to
"Proportional Head" and includes a differential by-pass on
the manifold.
