C) Connecting the Water Supply
IMPORTANT:
The flow to a fire suppression device must be ensured when using a domestic water
supply. This can be assumed when there is only a single pump connected because of its very low (6
lpm) flow requirement. However, if more than one pump is being linked to work simultaneously in a
fire, a survey needs to be carried out to ensure that there will be water supply available to both the
Automist pumps and the normal domestic supply in its worst condition. Otherwise a priority valve or
a booster pump may need to be used to provide the required flow and pressure. It is responsibility of
the installer to ensure the water supply to the Automist pumps is adequate.
The water supply should comply as follows:
•
A check valve must be installed to ensure back flow protection to the mains water (supplied in kit).
•
WRAS approved isolation valves (or equivalent) are required so that the Automist Smartscan
system can be shut off from the water main. All such valves should 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 should be used in circumstances where the water
supply may otherwise be inadequate.
Position the pump unit as closely as possible to the mains water supply pipes.
IMPORTANT:
If new pipe has been fitted, remember to flush out any contaminants before connecting to
Automist Smartscan, to avoid clogging the nozzle.
Connect the high pressure hose from the assembled head to the outlet on the pump. Plumis supplies
suitable high-
pressure hoses. If using another brand of hose, follow Plumis’s guidance note, available on
the Plumis Partner Site. All high pressure hoses should have a minimum working pressure of 150 bar,
minimum internal diameter of 6.3mm and a minimum burst pressure of 600 bar. For hoses longer than 4m,
Place sticker over valve body &
handle, ensuring both are
connected by the sticker
When valve is disturbed, the
sticker will disintegrate
