Congratulations on selecting a Dayliff SunFlo Solar Pumping System. They are manufactured to the highest standards and if installed and operated correctly will give many years of efcient and trouble free service. Careful reading of this Installation Manual is therefore important, though should there be any queries they should be referred to the equipment supplier.
Pumps can be installed in wells or boreholes and should be provided with fittings as indicated in Fig1. Piping options are Dayliff PVC for deep wells, galvanized steel or HDPE. The latter is recommended for shallower wells due to simplified lowering. When installing the pump ensure to fit the safety rope which can be used to lower the pump down.

When provided, separate Controllers should be located adjacent to the Isolator and care taken to ensure correct connections to the terminal block. The controller isolator must be 'off' during connections. 2.4 LOW WATER LEVEL PROTECTION Water level sensors are unnecessary when there is no risk of draw down to the pump.

SYSTEM OPERATIONS 4.1 PUMP Generally pump operation is fully automatic with pump flow starting with low output at around 8am building to a peak at mid-day and stopping around 5pm.
4.2.2 SunFlo-A Pumps are controlled by an internal motor controller with no external monitoring or adjustment provisions. However, pumps must be connected through the PV Isolator that also provides over-current protection. 4.2.3 SunFlo-B All SunFlo-B pumps are provided with an advanced MPPT controller that enhances pump performance by up to 25%.
Controls Time delay Speed button Solar battery diverter switch Speed Control – Modulates the pump speed by regulating pump efficiency. Turn fully clockwise for 100% efficiency and fully anti-clockwise for minimum 30% efficiency. This function allows PV module output to be shared between the pump and battery charging according to the set proportion and for reduced pump output in the event of over- pumping.
