The pump can become contaminated due to:
- An extremely high feed velocity.
- Connecting a seldom used supply line.
- Taking supply from a fire hydrant.
Before connecting the supply to the pump allow the water to run freely for a minute or so.
Before every starting:
Control the water filter in front of the pump regularly for cleanliness and change the filter
insert
- at high pressure pumps with a operating pressure up to 1500 bar every 100 operating
hours
- at high pressure pumps with a operating pressure over 1500 bar every 50 operating
hours
Never clean the filter insert. Rechange by new. Only use original HAMMELMANN-spare
parts!
A blocked filter can cause cavitation and damage the pump. Cavitation damages at high pressure pumps are
excluded from the guarantee.
