TROUBLESHOOTING GUIDE

SYMPTOM
Low water pressure, low flow
from pump.
The Onga Pantera Evolution should only be serviced by certified Pentair service agents. For
best results and to ensure warranty is not void, insist on use of only genuine Pentair service
parts.
To avoid dangerous or fatal electrical shock hazard, turn OFF power to pump and remove
plug from power outlet before working on pump.
The power supply cord has a type 'Y' attachment and if service is required to the power
cord, it must be replaced with the specialised power cord assembly by Pentair Water
service agent or similarly qualified personnel in order to avoid a hazard. Warranty is void if
unauthorised modifications are made to any component.
CAUSE
Suction leaks / lost prime.
Low speed setting.
Clogged pipe / strainer /
impeller / filter system.
REMEDY
Pump must be primed; make sure that
the pump casing and strainer are full of
water. Refer priming instructions.
Make sure there are no leaks in suction
piping and ensure all o-rings are present
and clean.
Make sure suctions pipe inlet is well
below the water level to prevent pump
from sucking air.
Suction lift of 3 to 6 metres will reduce
performance. Suction lift of more than 6
metres will prevent pumping and cause
pump to lose prime. In either instance,
move the pump closer (vertically) to water
source. Ensure that the suction pipe
diameter is large enough.
Check speed setting. Refer to speed
selection section of this manual.
Ensure trap is not clogged with debris;
clean basket and/or filter.
Make sure that the impeller is not clogged.
This should be checked by qualified
personnel only.
Pump may be trying to push too high a
column of water. If so, a higher pressure
pump is required.
