Sicce Syncra SDC 6.0 Manuel D'instructions page 11

It is recommended to place the pump in spaces where there is
a proper ventilation and the pump is not directly exposed to heat
sources.
Place the pump so as to prevent too long idraulic pipings, which
would reduce its performance.
Do not position the pump above the water level (Pic.2) because it
is not self-priming and the risk of the pump to run dry. The risk of
invisible air bubbles creating a vacuum area is very high. Damages
which are caused by the pump running dry are excluded from
warranty.
To maximize the pump's efficiency, choose a straight inlet tube
without elbows. (Pic.3)
We suggest an Inlet and outlet tubes with diameter equal or bigger
than the diameter of the threaded pipe included. (Pic.4)
Do not use the pump leaving the outlet totally closed. A minimum
water flow is necessary to keep the inner motor cool without running
dry (Pic.5)
