before beginning the installation.
Note solar PV examples are often
based on 270W panels. Today
280W or larger panels may be
more common/cost effective.
Please note that the intended
application of this solar pump is
for high country stock water
pumping from Spring to Autumn.
Operation in winter (or when
freezing temperatures may occur)
is only permitted if protection
from freezing is implemented.

1. Scope of Application and Safety
This document is part of the product. It refers to the PowerSpout React pump (formerly
called the SHP-TX Solar Hydraulic Pump Triplex) and the associated PV array, wiring and
pipe connections.
1.1. Scope
The product is designed to pump fresh water with the use of solar power (or other approved
power sources) in the following conditions:
The application of the React pump is to lift water on hill country farms for stock water
needs. If you plan to use (or store) this pump in conditions below freezing then extra
protection in needed to protect the React pump from damage due to freezing
temperatures.
Do not install unprotected in situations where the pipeline may freeze. Protection from
freezing temperatures is outlined later in this document. Frost will damage the pressure
sensor first, which is designed to fail safe and prevent operation of the pump.
Water that will not corrode aluminium parts. Seawater is not permitted.
Dirty pond water is acceptable within reason. River water that includes pumice or other
sharp abrasive material must be adequately filtered.
Terrain that can be walked over safely for pipe laying etc. (i.e. no large vertical drops).
The client confirms that the site is unlikely to: slip, have rock falls, flood, earthquake etc.
Where such conditions exist the client has taken appropriate measures (i.e. insurance
cover). Product warranty does no cover such events.
The client has read the manuals, viewed online videos and understood installation
examples before starting on this project.
We advise engaging an experienced/qualified installer who has good mechanical,
electrical, plumbing, reading and comprehension skills if you do not possess these skills
yourself.
The React pump must be sited above any flooding level unless pontoon mounted. React
pump submersion will result in serious equipment damage which is typically 50% of the
new cost to have repaired.
The React pump, solar PV array and power cable must be adequately protected from
large animal damage.
The client must determine:1.1.1.
Vertical lift from the React pump centre line to header/storage tank.
Size of header tank to meet their needs.
Length of pipe to the header tank.
Inside diameter of pipe to the header tank (already installed or available to purchase) to
allow for the extra friction pumping head to be determined.
Suction lift (vertical distance) from the lowest level of the water resource surface to the
React pump centre line (if a floating React pump on a pontoon is not being employed).
The suction pipe length. This must be less than 5m long, or the suction pipe size will
need to be increased from the 25mm ID to 30mm ID. Long suction lines should be
avoided where possible.
Maximum daily water requirement in summer, or the driest season.
Items that are provided with all pump sales (NZ & International):1.1.2.
React pump with pressure limit control
Thick rubber vermin guard
Inlet and outlet fittings (final pipe outlet fitting rated up to 16 Bar, > 16 bar threaded

Note: Some items above may be provided by a local dealer/supplier/installer in your country
or you can source them yourself. Many will be available on our website at the time of
purchase for an additional charge.
Note1Nominally based of 270W pairs. Panels in the range 250-325W are also acceptable
refer to 12.1.1.
Note2PV panel ratings tend to increase by 5W/per year for the same size. The best price
panel today (2019) is likely to be 280W. Last year it was 270W. This manual and
examples herein mainly refer to 270W panel examples.

1.2. Pump serial numbers
All React pumps have identification plates and serial numbers. We use the same plate as on
our hydro turbines.
For example:
You might see Serial number: 00235 as the serial number. This means you have number
235 made. Write the serial number in your records, as from this number we can locate when
it was made, when it was sold, to whom, software version etc.
If you ever need to query an installation or order spares for a product, take a picture of the
identification plate and forward it with your query.

1.3. Safety
The following safety warning signs are used throughout this manual.
Caution
Risk of electric shock. On this Solar ELV (extra low voltage) pump system
electric shock is very unlikely if these instructions are followed. All voltages
are ELV if the solar panels are correctly connected together. Incorrect
connection of >3 solar PV panels is LV (over 120VDC) and can result in
electrocution (and/or damage to the React pump speed controller).
Caution
Cautions identify conditions or practices that could result in damage to
equipment, fire, or personal injury, other than by electric shock.
EcoInnovation will not be liable if you connect this equipment incorrectly and in doing harm
yourself, harm others, cause a grass/bush fire or damage other equipment in your system.
This section addresses safety concerns as required by international standards and accepted
best practices.
If you are not technically competent, experienced and qualified you should not install this
equipment until after you have read this manual and watched all relevant videos provided.
Our INDEX provides links to the most recent version of all these documents/videos.
Equipment can be installed or operated in such a manner that hazardous
conditions can occur; compliance with this manual does not by itself assure a
100% safe installation. If the equipment is properly selected and correctly
installed and operated according to this manual, then any such hazards will be
minimized.
Rotational Machinery Safety1.3.1.
The PowerSpout React pump is rotating equipment and is provided with a
stainless steel protective enclosure. There are rotational hazards present if the
protective enclosure is removed. The React pump must be turned off at the DC
switch(s) prior to removing the protective enclosure. It is also possible to turn off
the React pump (if the PV array is distant) using the "ignition switch" which is located inside
the protective enclosure (on the end of the microprocessor enclosure). This can be also
wired to an external switch if required.
Note: a React pump can start rotating without warning if the DC switch is on and the
microprocessor switch is on.
Once the React pump has been commissioned, the protective enclosure needs to be
fastened in place with the latching tie-down provided.
The installer should ensure that the React pump is mounted such that
inquisitive children are not exposed to a rotational machine hazard.
Note: Direction of rotation is best anti-clockwise when looking on the electric motor end, this
direction provides slightly better lubrication on the plunger guide surfaces when run anti-
clockwise. For a full explanation view this video.

Pressurised Water Safety1.3.2.
In some countries, legislation covering pressurised pipes applies for pipe
pressures over 10 bar (100m head). The PowerSpout React pump often
operates at more than 10 bar. It is capable of pumping to 30+ bar (300m head).
Check with your local authority if you have any legal requirement that may
concern this installation in your country.
Generally there is little risk at less than 10 bar pressure. The biggest risk is insecurely
fastened pipe joiners that blow off, with the free end of the pipe hitting people. Securing the
pipe at regular intervals, particularly near the joins, and checking all joiners are tight and that
the pipe's pressure rating exceeds the pumping pressure will eliminate such risks.
Fire Safety1.3.3.
Solar pumping is often done in very dry parts of the world. In tinder-dry conditions the risk of
fire can be extreme. These manual instructions comply
with AUS/NZS 5033:2012 and AS/NZS 4509.1:2009, as
such if installed as per this document the installation
meets the requirements in NZ and Australia for ELV
systems. Not all countries have the same rules and in
many countries the rules are not clearly defined. Check
with your local electrician and fire department if you are
unsure of the rules in your country. Also call your
insurance company to check that your cover meets your
needs in this regard.
Warning: if you do not comply with standards/codes and
laws in your own country then your fire insurance may not be valid and if your inadequate
installation of this React pump were to cause a fire you could be personally liable for any
damaged caused.
The electronics in the React pump are contained in a metal enclosure to reduce the
fire risk.
The smart drive motor (stator and rotor) are made from fire resistant UL listed plastic
and are the same parts used in Whirlpool washing machines.
The pump outer casing is a metal skin. This product does contain a small amount of
combustible plastic material.
Where the risk of a grass or forest fire is real in your area, the following
measures shall be taken:
Mount the React pump on a concrete base at least 1m square.
Ensure the React pump is shaded if exposed to high summer temperatures. The
BLDC motor and pump do need cooling airflow. Provide shade but do not enclose it.
In pontoon applications (see pontoon section) no additional fire protection is needed).
Assessing the fire risk is the owner/installers responsibility:
The precautions required are the same as for petrol/diesel water pumps, which
have a high fire potential due to their liquid fuel and high exhaust temperatures.
The risk is small but the consequences can be very high, so please take the time
to ensure that your installation is fire safe.

Electrical Safety: ELV Wiring rules specific to NZ and Australia1.3.4.
Two definitions exist in NZ for ELV ("extra low voltage"):
Any voltage normally not exceeding 50 volts AC or 120 volts ripple-free DC
Any voltage not exceeding 50 volts AC or 120 volts ripple-free DC
AS/NZS5033 also defines “ripple free DC” as:
1.4.62 Ripple-free D.C.
For sinusoidal ripple voltage, a ripple content not exceeding 10% r.m.s.
NOTE: The maximum peak value does not exceed 140 V for a nominal 120 V ripple-
free d.c. system
All extra low voltage wiring should be performed by a 'competent' person, defined by
NZS4509.1 as:
"a person who has acquired through training, qualifications, experience or a
combination of these, knowledge and skill enabling that person to correctly perform
the task required"
Note –even with a reduced shock hazard there is danger of fire from
incorrectly installed ELV wiring systems. Note the word “should”is
advised (best practice) and not a legal requirement in NZ. ELV work in NZ
is classified as “non prescribed electrical work”. So you cannot break the
law as the law does not apply to this work, nevertheless you can be liable
for the consequences of improper installation practice. Do a quality job and seek paid
assistance if/as required.
This document and supporting videos are sufficient training and knowledge to enable a
capable owner/installer to perform the tasks required. If you feel you are not capable and do
not have the time to fully read and view our installation material (to become capable and
competent) then engage the services of an Electrician or Renewable Energy
Installer/Technician.
Wiring is simple. You will need to attach MC4 connectors from the Solar PV DC switch box
to the pump as the wire length/size will vary from site to site. All that is required is for the
installer to plug together the waterproof connectors (in the correct sequence) and secure the
wiring as per our supporting videos. If using three or more strings of solar panels you should
determine whether there is also a need for string fuses in the design. (See 3.2.3)
Installation Safety Checklist1.3.5.
The installation shall be carried out by installers, owners or contracted persons with relevant
experience and good practical skills relating to general water reticulation systems and ELV
electrical systems.
To meet good working practices and safety requirements for this installation, the installer
must:
GENERAL
Check for any transit damage to the product prior to installing it. If damaged it must
not be installed.
Connect equipment to a high standard to relevant good practices and standards.
Read and comply with this installation manual and supporting videos.

PIPES
Ensure both the suction pipe and the tank supply pipe are of the correct size.
Undersized pipes will reduce React pump performance and can result in pressure
blowouts and failure of the React pump to operate. There is a section later in this
document to assist with pipe sizing.
Do not confuse pipe ID with pipe OD when purchasing pipe.
Use standard LDPE, MDPE or HDPE pipes. The pipes must withstand the maximum
total pressure to which they are subjected. A safety margin is already included in the
pipe rating, this safety margin allows the pressure stop switch to operate without
rupturing the pipe. If you skimp on the pipe cost by installing 12 bar pipe when you
have 160m of head, the lower section of the pipe will likely rupture on a hot day once
the tanks is full - you have been warned.
In hot dry climates where the pipe lays on the ground the pressure rating must
be reduced to allow for the maximum temperatures. Burying the pipe protect
the pipe from physical damage, heat (pressure derating) and cold (damage due
to freezing). If necessary bury the pipe to protect it against heat, stock damage, rock
falls, tree falls, slips, avalanches, freezing etc.
PLUMBING WORK
Tighten all water connections with appropriate sealing tapes or compounds to ensure
connections do not leak.
Provide a suitable disconnection point fitted with a non-return valve close to the
React pump so that it can be easily removed for servicing.
The React pump includes a digital pressure sensor that monitors the pressure and
will turn off the pump when a set pressure is reached. The pump will stop if is detects
a pressure above 300m, this can be easily adjusted downwards or reset (a reset
returns default to 300m).
INSTALLING YOUR REACT PUMP
Make sure that you install the React Pump such that it will not be exposed to freezing
temperatures which may damage it. If the React Pump is only to be used from Spring
to Autumn to provide stock water for hill top gazing, then no extra freezing protection
may be needed, provided the React pump is removed to a dry/warm store for the
winter. Carefully read section 8.3.5 before you decide how best to install your React
pump.
COMMISSIONING
Securely fix the pump base prior to operation, at least 300mm above ground level to
allow for pipe and wire connection that enter via the underside.
Ensure:
Rodents cannot get access inside the pump.
Grass and other vegetation are prevented from growing into the pump via the
cooling vents. Cover the ground with corrugated steel or concrete to prevent
plant growth if required. Plant growth can be a significant fire hazard.
Do not run the pump without first adding oil. Each pump has been tested at our
factory, this testing oil is drained out prior to freighting.
Fill the pump body with clean SAE15W/40 (see section 8.6) to the top of the oil
level indicator glass. Oil level should never be less than the middle of the level
glass. A little higher than the top of the level glass is OK.
Do not intentionally run the pump without the water supply connected for more than
10s. Water is needed to cool and lubricate the ceramic plungers.
Do not run the pump at a supply head above 160 or 300m (depend on option
purchased).
To turn on the pump you must ensure:
Solar panel switch is on.
If pump fails to rotate check sunlight is on panels and that the microprocessor
switch is on.

Any float switch connected to the “float switch” connections is on.
Wiring has been done correctly.
MC4 plug connectors have been pushed fully home (this is a common error).
In a pump runaway situation (where the high pressure output pipe bursts) turn off the DC
switch to stop the React pump.
If you start the pump against a closed valve this will stall the pump. (You may also burst
your pipe or fitting.) It may also go into sleep mode as it thinks your water tank is full.
Turn off the solar power at the switch and wait 30s. Open the valve, turn the switch back
on and it will run fine.
Check for excessive noise. There should be little/modest noise from the pump. Get
familiar with what your React pump normally sounds like.
Check water is being pumped at the expected rate for the sunlight conditions.
Ensure that all protective fairing/enclosures are locked in position after commissioning.
Complete sensible signage requirements to help with pump maintenance and as
required for AS/NZ 5033 compliance.
Complete all documentation and take picture of your installation and the serial number
identification plate.
Make relevant notes in the manuals that will be of assistance to yourself and any future
service personnel.
If installing the React pump for a client then all of the above must be completed before
client handover.
Train the client/user of the pump in routine care and maintenance of the React pump and
general solar system.
SERVICING
Keep the React Pump packaging and red oil transport cap. If you ever need to return the
pump under warranty or for factory service you will need to: drain out oil, fit red oil
transport cap and repackage for freight in a similar manner to which it was received.
Hold is stock a complete spare parts kit, spare suction hose, spare foot valve, spare foot
valve filter sock, spare SAE 15W40 oil.
Check oil level and ensure level is always close to the top of the sight glass. If oil level is
allowed to fall below the bottom of the sight glass serious damage may result.
1.4. CE and FCC Declaration
Refer to PowerSpout Document INDEX for compliance declaration documentation.
The React pump pump contains electrical or electronic components.
The React pump will be tested for radiated emissions as soon as practically possible.
The fact that the BLDC driver and Smart Drive BLDC motor are mass-produced & globally
available means that it is likely that they already comply. We will provide an EMC lab test
report in due course. Once tested the certificate can be located in our INDEX.
1.5. Standards and certification
All PowerSpout pumps have been evaluated against the relevant sections of major
international standards in regard to rotational machine safety and the restriction on the use
of hazardous materials in the manufacture of the React pump.
The React pump has a metal casing and meets product safety, impact durability and freight
drop test requirements.
Refer to PowerSpout Document INDEX for more information.
