Operation
Completely fill the plumbing system before operating the pump. Do not start the pump until the plumbing system
has been filled. Make sure isolation valves are fully open and the pump is flooded with water. Purge air from the
plumbing system prior to operating the pump. This can be achieved by loosening the plumbing connection at the
pump to allow any air present, to escape. These 2 steps are very important. The pump can never be allowed to run
dry as this can severely damage the pump and will void warranty. Operate the pump. Ensure water is pumping
through the plumbing system. Turn off immediately if no water is flowing within 30 seconds. Once running
correctly, recheck after 5 minutes to ensure continued proper operation. It may be necessary to open a discharge
valve, port or fixture to ensure all air is purged. The pump should be running quietly. If gurgling is heard, it may
mean that air is still in the system. Turning the pump on and off several times will generally clear remaining air. If
gurgling noises persist, recheck and purge the system (note that ozone injection can make a gurgling sound at the
injector and not be a pump issue). Dry run protection. Pump motors are fitted with dry run protection to preserve
the MOTOR. If a dry run condition occurs, the motor will stop and restart numerous times in the attempt to purge
air. If this condition remains, the motor will turn off and remain off until the power is interrupted. This does not
guarantee protection of the wetend / rotor bearing as dry running can cause failure NOT covered by warranty. This
dry run motor protection prevents motor failure. A failed rotor due to dry running or chemical / water condition
damage, can be ordered from Australian Spa Parts and replaced rather than a complete pump.
Trouble Shooting
Motor will not start or run: Improper electrical connection, blown fuse or circuit breaker, loose or broken wiring,
foreign object stuck in impeller, motor failure, dry run motor protection has operated. Pump will not prime: leak,
kink or obstruction in suction line, pump is worn, dirty / blocked filter Little or no discharge: Air in pump, suction
blockage, head to high, blockage in pump, pump not running, dirty / blocked filter Noisy operation: Air in pump
housing / dry running, worn rotor bearing, debris in pump.
