MAINTENANCE

Regular maintenance is essential if the pump has to give good service over a long period. The following
advice should be strictly followed.
Before any operation, make sure the system is unplugged!
Weekly operations:
Check the level of the liquid to be dosed to avoid the pump working dry
-
Check that in the suction and injection pipes there are no impurities
-
Check the filter clogging, which may cause the decrease of flow rate
-
Operations every three months (or in case of pump drifting):
Cleaning: clean all parts that are in contact with the dosed chemical (pump body, foot filter and
-
injection valve). If using additives that form crystals, clean more frequently.
Proceed as follows:
o Immerse the suction tube and foot filter into a tank containing clean water
o Start the pump for a few minutes to let the water pass through the pump body
If there are crystals to be removed, proceed as follows:
o Replace the water with an adequate chemical (e.g. hydrochloric acid for sodium hypochlorite
crystals) and let the pump work for a few minutes
o Repeat the operation with clean water
Once completed the cleaning, the pump can be connected again to the plant and start to work.
Extraordinary maintenance – Replacing the fuse:
This operation must be performed only by qualified personnel. If the intervention of a technician
is not possible, send the pump to the manufacturer for proper maintenance.
