ORANGE HD50 Installation Instructions Manual

Installation Instructions
HD50 Solar Pump

Assembly
drawing

The solar pump must be connected to 36 volt solar Panels

When connecting the pump make sure the electrical red

pump lead on the pump is connected to the positive on the
Solar Panels. The plugs provided should make the
electrical connections correctly.

The pump and motor must be protected from the weather.
When assembling the pump make sure the flow switch is
plugged into the motor and the water flow is in the correct
direction.

Installation

Pipe used on the suction and discharge should
be 25mm if the pipe length exceeds 100 Metre
then a pipe friction table should be checked and
if required a larger pipe used.
Care should be taken with the suction pipe.
Suction pipes should be layed with an even
gradient so that air trapped in the pipe is
minimised when primming the pump. The
vertical suction is limited to 6 metres at sea
level.
A foot or check valve must be used in the
suction pipe.
When first primming the pump it is easier to
remove the flow switch and pour water directly
in to pump outlet. Later the primming plug can
be removed to bleed trapped air. All air has to
be removed for satisfactory pump operation.
Pipe should be buried to stop the sun from
heating the water and effecting the suction
ability of the pump.
If sucking from a dam etc consideration should
be given to floating the foot valve and using a
large suction strainer to prohibit foreign matter
entering the pump

Remove strainer
and replace with
large suction strainer
to help stop foreign
matter entering the
pump.

?The pump will operate automatically. If it stops it will wait for 10 minutes and

then try to restart. For emediate restart push the reset button.

?If the green lights are rotating the pump is running normally if they are blinking

there is something wrong, loss of prime, flow switch off, lack of sun light, etc

?If the red light is on the power is on, if it is blinking the motor is running hot.

Panel Watts

Solar Panels

Any type of solar panel can be used
which has an operating voltage of about
36 volts and an open circuit voltage of 45
to 47 volts and combined wattage as
chosen from the graph. If using panels in
parallel you can buy our solar leads for
plug in assembly.
If not using panels to this specification
high voltage panels must not be used low
voltage can probably be compensated for
by using more panels.
