SERVICE & MAINTENANCE
If water is seen to be leaking from directly underneath motor
and casing, have pump serviced immediately. This indicates a leaking mechanical
seal. Failure to fix this may result in premature product failure.
NOTE: Onga recommend the use of silicon based lubricant on all ‘O’rings.
The only routine maintenance needed is inspection/cleaning of leaf basket. Debris or
trash that collects in basket will choke off water flow through the pump. Follow
instructions below to clean leaf basket:
1. Stop pump, disconnect from power, close gate valve in suction and discharge.
2. Unscrew lid (turn counter clockwise). If necessary, undo drain plug to reduce lid
vacuum. Do not hit the lid with a hammer or similar tool. If the lid is still too tight use
a lever such as a board or long screwdriver between lugs on lid.
3. Remove leaf basket and clean. Be sure all holes in basket are clear, flush basket with
water and replace in bowl assembly with large opening at pipe connection port
(between ribs provided). If basket is replaced backwards the lid will not fit into bowl
assembly.
4. Inspect, check and lubricate lid 'O' Ring; reinstall onto bowl assembly.
5. Clean 'O' Ring groove on bowl assembly and replace lid. To help keep lid from
sticking, (tighten hand tight only no wrenches!).
6. Prime Pump (see priming instructions)
NOTE : Failure to carry out routine maintenance may reduce pump performance
and void warranty.
