TPS20TM PRODUCT MANUAL
The performance of the pump depends on sunlight
intensity and the incident angle at which sunlight strikes
the panel surface.
The latest DC brushless motor technology is introduced in
the pump design and manufacturing, so that the pump
has higher efciency and a longer service life.
The solar pump is powered by a solar
panel. In order to make the pump work
by solar energy, the solar panel needs to
be placed in the sunlight with its solar
cells facing the sun as much as possible.
Ideally, set up the solar panel
facing north at 45 degrees to
the horizontal. (Facing South if
in Northern Hemisphere)

ASSEMBLING
1. Unpack all components carefully. See Figures 1
(unassembled) and 2 (assembled) below.
2. Fit a square tube 75mm x 50mm x 2.5mm x
500mm long (NOT SUPPLIED) to the solar
panel hinges TPS50
3. Erect a wood or steel pole next to the trough
high enough so when the solar panel is tted,
animals cannot interfere with the solar panel
and its parts (photo 1).
4. Adjust the angle of the solar panel to face true
north as closely as possible.
5. Place the pump in the trough as per
instructions, and t riser tubes and outlet to
the correct height as shown in the instructions
(page 6).
6. Run the power cable to the solar panel. The
power cable is protected by a metal spiral
convoluted tube. This must be securely
attached to the pole to ensure minimal
interference by animals.
7. Connect the pump power cable to the ON/
OFF switch cable and then to the solar panel
power cable, taking care with the terminal
position. Lock the two power cables in place
using the nut on the solar panel power cable.
Ensure the pump remains fully submerged in
water while the pump is in operation.
8. The solar pump is now ready to operate.

INSTRUCTIONS
Round Troughs
Place the pump in the centre of the round trough, making sure that it cannot be reached by livestock.
It is recommended that the pump is covered by mesh, or a mesh cage, for protection from the animals
being watered.
For best results, the outlet tube should be submerged below the water level between 50mm to 100mm.
This should result in a short fountain and wave type motion throughout the round trough. For the larger
round troughs, the Y piece can be tted to the outlet tube between approx. 25mm to 75mm above
water level.

Placement of TPS-20 Pump in Short Rectangular Troughs up to 2.5 Metres Long.
Short Rectangular Troughs up to 2.5 Metres
Place the pump at the oat cover end of the trough, ensuring it does not interfere with the oat valve
operation. The outlet tube and Y or T piece outlet should be approx. 25mm to 75mm above water level.
Screw the threaded cap on the threaded outlet of the Y piece to ensure only one outlet of the Y piece
is open. Direct the open outlet of the Y piece towards the centre of the trough, so the outlet sprays the
water to the end of trough, forming a wave like motion.

POWER CABLE PROTECTION
PROTECTION
It is critical that the Pump and the Power Cable are protected at all times.
The power cable should be completely concealed.
Pump protection
A reinforced mesh cage is recommended, or the use of other suitable means to ensure animals cannot
access the pump system.
Example of mesh placed over pump at water level.
The power cable should be protected inside a metal tube and protected as it enters the trough. Excess
cable should be tied or clamped under the solar panel ensuring it is not accessible to the animals
(clamps supplied in Kit)

Notes:
• The power cable is protected by metal spiral
convoluted tube. This tube must be securely
attached to the pole supporting the solar
panel, with tube saddles provided. The power
cable can also be ran down inside the metal
tube to the height of the trough
• The solar panel should be cleaned regularly in
all conditions. A damp cloth or window washer/
squeegee is recommended.
• Trough standing water level should always be
at least 100m to 150mm below the top edge of
the water trough.
• Trough water level should be adjusted if water
from the pump is being blown out
of the trough by the wind.
• Please refer to the Croc-TPS website
for photos of different ways to install
the Croc-TPS.
• The solar panel is tted with a red light
to indicate the solar panel is operational,
but it does not indicate the amount of
power the solar panel is generating.
• The Croc-TPS is not a trough cleaning device.
The lter is tted to protect the pump from
becoming blocked and causing damage to
the pump.
• The solar panel must be installed on a strong
wooden or steel post, out of the reach of
the animals being watered, so there is no
interference with the solar panel and its parts.
• Pump lter should be cleaned regularly
depending on the situation. A coarse
laundry brush is recommended.
• The trough should be cleaned thoroughly
before installing the pump system.
• If algae is present, it is recommended to treat
the trough with an Algaecide to kill the algae
cells present in the trough.
• Animals are very inquisitive; they will tamper
with and chew on any loose materials when
bored. So, it is imperative that pump and cable
are secured and protected from all animals.
• The TPS has been trialled in many
different trough designs/types.
We can only recommend a basic
installation and protection method.
