The following condition must be fulfilled:
Σ (F ), Σ (F ) and Σ (M ) are the totals of the absolute amounts of the
V H t
corresponding loads acting on the connecting pieces. For these
totals, neither the direction of the loads nor their distribution is taken
into consideration.
NOTE:
When pumping out of a tank, ensure that the liquid level is always
high enough above the suction port of the pump so that the pump
never runs dry. The minimum inlet pressure must be observed.
• When the pump is used in air-conditioning or cooling systems, the
condensation that forms in the lantern can be drained specifically via
an existing hole. A drain pipe can be connected at this opening. Small
amounts of fluid leakage can be also drained off.
The motors are equipped with holes for condensation which are
sealed with plastic plugs at the factory (in order to guarantee that
protection class IP 55 is achieved).
• If used in air-conditioning/cooling systems, this plug must be
removed downwards so that condensation water can drain.
