Overhaul
•
The pump must be overhauled even though it operates properly. In continuous or repeated
operation, the pump may need to be overhauled earlier.
NOTE:
For pump overhaul, contact a Pumpa a.s. service centre.
8.1 Storage
If the pump will not be used for a long time, take it out, let it dry and store it inside.
NOTE:
Before reinstalling, start the pump for a test run. If the pump remains submerged in water, run it regularly
(i.e., once a week) to prevent rust from blocking the impeller.
9 Troubleshooting
DANGER:
Danger of injury. Do not repair the control panel if it is live. Electrical repairs must be done by a qualified
electrician to avoid serious injury, death and/or property damage.
WARNING:
Always disconnect the pump from the power supply before repairs to avoid serious injury due to
unexpected starting.
Read this manual carefully before requesting repairs. If the pump does not operate properly after
rechecking, contact a Pumpa a.s. service centre.
Problem Cause Solution

are low.
Worn impeller or suction cover. Replace.
Hose may be bent or blocked. Reduce the number of hose bends to a minimum. (In areas with
large amounts of debris, place the pump in a mesh basket.)
