•
The pump located such that it is: a) unlikely to be affected by a fire b) protected in the
event of fire; c) unlikely to be affected by flooding.
•
A 3/4” water supply (connection) with an appro
ved isolation valve located inside the cupboard and
positioned so that the connection point will not be obstructed when the pump is installed.
•
A cold water supply which can deliver 6 litres per minute flow at a minimum of 1 bar (100kPa) and
a maximum of 10 bar (1MPa) static pressure. If multiple Automist units are to operate
simultaneously, a proportionately higher flow will be required.
•
A dedicated electrical supply circuit in FP200 cable.
•
If the consumer unit is located in the same fire resisting compartment as the protected area, it
should be protected by an electrical cover unit tested to BS476 Part 22 (1987) & EN1364-1 (1999).
•
Flexible high pressure hoses should be mounted as close to the ground as possible and within the
wall. For cases where the hose is exposed, conduit sleeves must be used. Where the hose is
surface mounted more than 1.2m from the floor in a protected room, or where the hose passes
above/within the ceiling of a protected room, a suitable thermally insulating sleeve may be
required.
Never
use old hose sets, only use new hoses for each installation. Contact Plumis
technical support for more details.
•
Note:
When installing flexible high pressure hose behind plasterboard walls, Plumis advises the
hose is left free and unconstrained.
This is because mounting the hose in a conduit
or narrow
groove within joists makes it more susceptible to perforation when subsequent building works are
carried out.
•
Operating ambient temperature: above 4°C.
Spray Head Placement
The Automist Head is designed to be affixed to a standard 50mm deep single-gang mounting box (85mm x
85mm with fixing centres offset centre to centre by 60mm).
IMPORTANT:
The Automist head must be located where the spray pattern will not be obstructed and
750mm clearance is provided adjacent to each of the active nozzles. The nozzles must be installed between
1400 - 1500 mm from the ground.
When installing between a work surface and the cupboard, it is better to have the spray head as high as
possible within this space, as long as it 120mm from the lowest point on the cupboard.
