Maintenance and repair
WARNING
Sharp edges on the impeller and suction port!
Sharp edges can form on the impeller and suction port. There is danger of limbs be-
ing severed! Protective gloves must be worn to protect from cuts.
WARNING
Hand, foot or eye injuries due to the absence of protective equipment!
Danger of (serious) injuries during work. Wear the following protective equipment:
• Safety gloves for protection against cuts
• Safety shoes
• Closed safety goggles
The following pre-requisites must be fulfilled prior to starting maintenance measures:
▪ Pump cooled down to the ambient temperature.
▪ Pump cleaned thoroughly and disinfected (if required).
Check connection cable for:
▪ Bubbles
▪ Cracks
▪ Scratches
▪ Abrasion
▪ Pinch points
If damage is identified on the connection cable, decommission the pump immediately!
Have the connection cable replaced by Wilo customer service. Only operate the pump
up again once the damage has been properly remedied!
CAUTION! Water may penetrate into the pump due to the damaged connection
cable! Water ingress leads to total failure of the pump.
Accessories must be checked for:
▪ Correct fixation
▪ Smooth function
▪ Signs of wear, e.g. cracks caused by frequencies
Any defects detected must be repaired immediately or the accessories must be re-
placed.
The coatings and housing parts must not show any signs of damage. If there are de-
fects, the following must be observed:
▪ If the coating is damaged, it must be restored.
▪ Contact customer service if housing parts have worn out!
To test resistances, the pump must be cooled down to the ambient temperature!
Measure the resistor of the temperature sensors with an ohmmeter. The bimetallic
strips must have a measured value of 0 Ohm (passage).
