D) Second Fix - Connecting the Water Supply
IMPORTANT!
The flow to a fire suppression device must be ensured when using a domestic water supply.
A survey must be carried out to ensure that there will be water supply available for the Automist pumps
and the normal domestic supply in its worst condition. Otherwise, a priority valve or a booster pump must
be used to provide the required flow and pressure. It is responsibility of the installer to verify the water
supply to the Automist pumps complies to the requirement (See Section
The water supply must comply as follows:
•
A check valve must be installed to ensure back flow protection to the mains water (supplied in kit).
•
PRV must be installed to protect the system from overpressure or water hammer.
•
See Figure 2 for installation sequence.
•
WRAS approved isolation valves are required so that the Automist Smartscan Hydra system can
be shut off from the water main. All such valves must be labelled with the included warranty void
anti-tamper sticker. This enables clear identification of any tampering with the water valve (note:
spare stickers can be ordered from Plumis)

•
Priority valves are not normally required but must be used in circumstances where the water
supply may otherwise be inadequate.
IMPORTANT!
If new pipe has been fitted, remember to flush out any contaminants before connecting to
Automist Smartscan Hydra, to avoid clogging the nozzle.
IMPORTANT!
Before planning and installation, it is recommended to carry out a study on hose routing
regarding minimum hose length for connecting multiple heads to the Automist pump. See Appendix C for
Place sticker over valve body &
handle, ensuring both are
connected by the sticker
When valve is disturbed, the
sticker will disintegrate
