Translation of original operating manual

9.3. Cleaning/replacing valve plates and pump

diaphragm

Pump must be switched off and mains plug removed from
the socket.

The pump must be free of any hazardous substances.

Hoses must be disconnected from the pump head.

Qty.

Tool/material

Phillips screwdriver No. 1

Spare parts kit (see Chapter 11)

Tab. 24: Tools/materials

Always replace valve disks, valve seats and seals at the same

time, to maintain satisfactory flow rate performance.

WARNING

Health risk from hazardous substances in the pump

Some pumped media involve the possibility of
corrosion damage or intoxication.

Use protective equipment if necessary, e.g.

protective gloves, goggles.

Flush pump with a neutral fluid and then pump

empty.
