3.2 Tank-mounted confi guration
This section describes how to mount an SE Flowstar pump
station onto an SBB tank using a low tank mounting kit.
These components are sold separately.
1. Remove the pump station from the packaging.
2. Pull off the front shell.
3. Observe the lower connector of the pump station.
Remove the ¾˝ NPT adapter, revealing a ¾˝ BSP threaded
connection.
4. Inspect the threads of the tank to make sure they are
clean and free of debris.
5. Connect the pump station to the system by means of the
top and bottom connections. The bottom connection should
be piped to the heat exchanger outlet of the storage tank.
The top connection should be piped to return to the collector
fi eld. It is recommended to ensure the seal of all threaded
connections by using tefl on tape and pipe dope.
6. To prevent thermosiphoning, install a check valve in the
supply line of the solar circuit.
7. Connect the discharge line to the pressure relief valve
connection. Pipe this discharge line to a heat-resistant
container.
