Model Current Voltage (kg) Voltage Ø (VDC) SUNFLO-X 600H Helical Rotor 60-120VDC SUNFLO-X 1200H Helical Rotor 120-160VDC Centrifugal SUNFLO-X 1800C 120-160VDC 1040 Ø 2. SYMBOLS AND WARNINGS Misuse will result in fire, serious injury to person or even death. DANGER Misuse may damage equipment or cause light to medium injuries to a person. - Page 6 Earth terminal must be reliably grounded or else inverter enclosure may be electrified. WARNING The selection of solar array, motor and inverter should be compatible. In case of doubt, consult nearest Dayliff dealer. NOTE Terminals should be tightly fastened or else there is risk of arcing and fire.

Page 7: Installation And Wiring
The temperature of heat sink is normally high when inverter is running and it should not be touched or else it may cause burns. WARNING For areas with altitude over 2000m, the inverter output current should be derated at 10% for every 1500m increase in height. WARNING Maintenance and inspection must be performed by a qualified technician. - Page 8 When positioning the pump it is important to ensure adequate motor cooling Ÿ through water flow past the motor. This will be achieved by installing the pump suction above the borehole main aquifer or well screen and if not possible or in cases of open water installation a cooling sleeve must be used.
- Page 9 As the valve is being opened, the water output should be monitored to ensure that Ÿ the pump output does not exceed the borehole capacity as indicated by the pump starting and stopping on the low level relay (if fitted) or uneven water flow at the outlet.

Page 18: Troubleshooting
5. TROUBLE SHOOTING 5.1 Fault Codes Description and Counter Measure DC solar pumping inverters have complete protection functions. When system fault occurs, the inverter will take protection counter measures: The general protection measure is to stop the inverter immediately and not allow the inverter to restart in a while. When fault or protection occurs, the inverter operation panel will automatically display the blinking fault code in the last 2 digit nixie tubes. - Page 19 5.2 Other Codes Description Relevant Description Code Code Description p 1.u.
