6.2 Direction of rotation
Simple control of the direction of rotation with push button:
Compare the motor shaft’s direction of rotation
with the direction of rotation indicated on the type plate.
6. Initiation/operating control
6.1 Generalities
Fill and de-aerate the system properly.
Only put the pump into operation when the system is full.
Switch on the distribution voltage.
6.3 De-aeration
The pump, and especially the engine compartment,
is automatically de-aerated after a brief operational period.
If a very quick de-aeration is desired, proceed as follows:
– Switch off the pump
– Lower the system pressure to 0.2 bar
– Loosen the screw plug (roughly one turn counter-clockwise)
until water comes out.
Depending on the temperature and the system pressure,
the hot pumped fluid may be emitted as a liquid or a gas.
– Never remove the screw plug completely
The pump may suck air in.
A great volume of fluid may be lost.
– Switch the pump on and off some 5 to 8 times
until only water comes out of the screw plug.
– Tighten the screw plug.
– Increase the system pressure
– Switch the pump on.
There is a danger of scalding
The desired flow rate is set using the turning knob
on the pump’s electronics.
(infinite from e.g. 1 to max).
The pump can be set to the system’s specific needs using
infinite adjustments.
(Flow volume V [m

Setting value:
– Specifications of heating planner
– Start with the first level.
If the heating elements removed do not become hot,
raise the settings to a higher level. Wait for a reaction.
6.4 Output regulation
Fit correct cover on electronics
(with several pumps).
Refer to type designation in cover.
