7.2. React pump Components
In order to reduce the length of this installation manual, instructions on how to service and
assemble the React pump are in a separate videos that will be available from 2020.
for our React Pump YouTube channel
NEVER work on your React pump while it is in operation.
React pump Protection
7.2.1.
React pumps arrive fully assembled, other than oil.
The PowerSpout React pump is encased in a durable housing, ensuring all internal parts are
protected from rain, rodents, children and UV.
This housing does not provide freezing
protection, the installer must make provision to ensure that the React Pump is not
exposed to freezing temperatures.
7.3. Commissioning procedures
Checks with cover off - before start-up
7.3.1.
These tests ensure you have completed the plumbing connections and have no leaks.
By this stage you should have:
Installed the suction (foot valve and filter sock) or a gravity feed intake.
Securely attached the React pump to a suitable base.
Connected React pump suction and delivery pipes.
Connected the delivery pipe to the tank with a ball cock fitted (inside the tank) if you
want to React pump to turn off when full.
Filled the React pump with SAE15W/40 oil
to the top edge of the level glass
.
Manually primed the React pump suction line if required (if suction head exceeds
3m). If you pipeline to tank is already full of water you will need to open the bypass
valve to purge out trapped air before closing again.
Ensure the on/off switch on the BLDC is on.
Secured all protective fairings.
Commissioning the React pump
7.3.2.
Check that there is sufficient sunlight for the solar panels to provide adequate power. Turn
the React pump on at the switch. Provided you have good sunshine on the panels the React
pump will start to rotate. It will spin fast at first, and there should be little noise. As the
delivery pipe fills with water and the backpressure builds up, the React pump will steadily
slow in speed. While the pipe is filling keep an eye on the React pump pipefittings for any
leaks. Turn off and fix them if observed.
If the delivery pipe is already filled with water following a React pump service (for example).
You will need to open the bypass valve for air to purge from the React pump. After 15-30s of
observed water flow this valve can be closed.
Once the sun gets too low in the sky there is not sufficient power for the pump to continue to
work and it will stop. It may still attempt to start (clicking noises) but will in due course stop
completely. Likewise, on sunrise the pump will attempt to start and in due course will run
continuously increasing speed with sun intensity.
