Please read these instructions fully before starting the
installation:
The installation must comply with the relevant water supply,
electrical and building regulations and be installed by a
competent person.
If in doubt, consult Stuart Turner Ltd.
APPLICATION
The range of Automatic Flow Switch pumps is designed for pressure boosting
applications in vented stored hot or cold clean water systems where under gravity some
flow is available.
Other clean, non aggressive, non explosive liquids with similar characteristics to water
may be pumped, consult Stuart Turner for such applications.
