Postioning
Using the fixing holes indicated by the green arrows, mount
the controller close to the water source and low down
so that the pump inlet (for standard pump) is below the
water line in the tank – for the submersible pump it can
be mounted at a convenient height. The controller case is
weather resistant but can be mounted inside if desired.
The solar panel should be mounted, facing the midday
sun and has a 5m cable, a 5m extension can be added if
required. The panel can be connected and screwed tight to
the socket hanging from the base of the controller.
The kit is supplied with a choice of water pumps.
Internal diaphragm pump. (fig 1) This pump delivers
about 1.5lpm at 3 bar pressure and is ideal for use where
the outlets are 2 – 5m higher than the water source.
However, it is not very good at self priming so needs to be
situated low down where natural flow from the tank will
avoid the problem.
Submersible pump. (fig 2) This delivers more water at
a lower pressure, the volume delivered varies with the lift
required to reach the outlets but up to 2m will be higher
than the diaphragm pump. As it is submerged it does not
require priming. In a typical situation it will deliver 50%
more water per week from the same amount of solar
power, but it will be at a lower pressure which reduces the
risks associated with over-pressurisation, especially with
micro-porous hose. It is also very quiet.
If the submersible pump is required, leave the diaphragm
pump in place, but unplug it from the circuit board. The
submersible can be plugged in, in its place and the
moulded in grommet used to fit it into its designated slot
in the case.
