11. Installation cont.
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.
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.
•
The voltage shown on the nameplate of the controller and motor must match.
•
Never install additional solar panels other than what has been supplied. The maximum
and voltage and current specifications must be respected.
•
Fit the low-level float to ensure the pump switches off should the water level fall to
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.
•
Water temperature has an impact on pump performance. Recommended water
temperature of 10
°
to 40
°
C.
•
A check valve is included with the kit. It 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.
Borehole installations
•
Damage to the pump or motor caused by abrasive or corrosive water is not covered
by the Warranty.
To prevent damage to the pump by aggressive water, an analysis of the bore water
should be carried out prior to installation to ensure pump suitability.
Note
: Sand content not to exceed 100g/m3 of water pumped.
•
The bore must be clean before installation. A helical pump must NEVER be used to
bail a new bore. Warranty does not cover failure or wear due to abrasives in the
water.
•
Know the total depth of the bore and ensure that the pump does not rest on the
bottom or in sand. Ensure 1.5 metres clear below the pump to the
bottom of the bore.
•
Know the pumping level (drawdown level) of the bore and ensure
that the pump remains submerged.
Minimum water level should be 150mm above the pump inlet
•
Never install borehole submersibles in a crooked bore without
first lowering a gauge which is the same diameter and length as
the pump to be used into the bore.
If the gauge does not bind, it is safe to install the pump.
