MAINTENANCE
Regular maintenance, cleaning and inspection of the pumps is extremely important. This will reduce problems and increase
operating safety and reliability.
MAINTENTANCE
Maintenance of the product should be carried out only by specially qualified personnel.
Before starting the pump after extended non-use or when restarting in the spring, it is advisable to turn the motor shaft, with
the pump switched off and the pump full of water, by means of the motor fan using a screwdriver. This will free the shaft seal
and make starting the pump easier.
