iSOLAR PDP4 pump installation notes
White International shall not be held responsible for damage caused by
improper installation, use of incorrect cable specifications, negligent or careless
handling, lightning, improper voltage supply, corrosion due to impure water,
wear caused by sand, gravel or other abrasives in the water being pumped.
•
Only suitable qualified personnel should carry out electrical connection/disconnection
•
Off-grid electrical equipment is subject to regional and national electrical standards
•
The iSOLAR PDP4 motor has internal capacitors that MUST be allowed to discharge before
handling. Allow 2 minutes for stored energy to dissipate before handling the pump/motor
The water source must be clean water free from contamination such as dirt, dust, loose
rocks, decaying organic matter or any other foreign bodies that could block the intake.
Sand greater than 100g/m

will accelerate wear and shorten the lifespan of
progressive cavity, helical rotor pumps such as the PDP4. Warranty does not cover
failure or wear due to abrasives in the water. The stator and rotor are considered wear
parts and will require replacing as pump performance diminishes with age.
GENERAL PRECAUTIONS
•
Never support the weight of the pump by the drop cable/safety rope or by the
power cable. An unstrained safety rope must be connected to the bore pump
suspended on poly pipe. This line should be fastened to the lifting hook of the
pump. The other end should be fastened at the top of the bore casing/cap.
•
Fit the low-level float to ensure the pump switches off should the water level
reach 150mm above the pump suction inlet.
An absent or inactive low water level float will result in damage should the
pump run dry voiding warranty.
•
A check valve must be installed on the pump outlet or at the well head.
Additional check valves for heads greater than 80 metres may be necessary.
These will reduce water hammer shocks to the pump.
PUMP SHROUDING
A shroud is essential if the current drawn by the motor is above 2kW. The optimum
cooling will be achieved by a water velocity of 80mm/sec past the motor.
Estimated motor consumed wattage = total wattage of the solar array and less 30%.

Example: If the total size of the solar array is 3000W, less 30% = 2100W.
At peak power, it is expected to be above 2kW, so fit a shroud.
