Service and Maintenance
Pump should only be serviced by qualied personel.
To avoid dangerous or fatal electrical shock hazard, turn OFF power
to motor and remove plug from power outlet before working on pump
or motor.
Liquid may be HOT, release pressure with care before servicing.
1. General Care and Maintenance
No lubrication or regular maintenance is needed beyond reasonable care. When pump
is not in use for a long period of time, empty the pump, rinse it with clean water and
place it in dry storage.
In order to prevent possible failures, it is advisable to periodically check the pressure
supplied and power absorption. A decrease in pressure is a symptom of wear. An
increase current absorption is a sign of abnormal mechanical function in the pump
and/or motor.
1. Start-up / Operation
When the power is turned on, the pump will start, and stop as soon as it has pressurised
the system it is connected to. If the pump does not start, press
the ‘restart’ button on the front of the pressure controller. Open a tap, (or garden hose
nozzle) and the pump should start and deliver water. When the tap is closed, the
pump will stop once pressure is built up in the system. The system is now working
correctly.
If no water is delivered, check the troubleshooting section of this manual, and
additionally, refer to the pressure controller installation and operating instructions
packaged with the controller.
