Replacement set for solar pumps

How to replace the pump

• Dismount the asynchronous pump and replace it with a high-efficiency pump.

• Connect the PSW to the controller (to the same relay to which the previous pump

was connected to).

• Connect the PSW to the pump plugs and plug the safety plug into a socket. The PSW

is correctly preset for the pump.

Complex solar installations can thus be operated with the existing controller.

Whether it is the replacement of a faulty asynchonous pump or the increase of the efficiency of an

installation: The PAW service team is happy to assist you in the selection of a high-e

fficiency pump

with an appropriate characteristic curve.

What is the situation with domestic hot water installations?

PAW domestic hot water modules are equipped with perfectly matched components such as heat

exchanger, pumps, sensors and controllers. The pumps are usually designed as high-e

fficiency pumps.

To ensure the usual temperature stability after replacing a component, please contact our service team

and keep the serial number of the station at hand. The serial number is placed in the lower right corner

of the retaining plate of the station. We will gladly submit you a specific recommendation for

replacement.
