Installation requirements
•Before installing, ensure that the following have been provided at the installation site:
•Sufficient space to install the pump in accordance with these installation instructions. The pump is 14.37
inches (365 mm) (height) by 9.45 inches (240 mm) (depth) by 7.13 inches (181 mm) (width) and weighs 15.43
pounds (7.0 kg). Pump shall be placed on a flat smoth level surface. Pump is Type 1 automatic operation
and specified for Pollution Degree 3 (dust damp conditions). The rated impulse intake voltage is 1500V.
Data port connections are 24 VDC and classed as PLEV (protected extra low voltage circuit) system.
•The pump should be installed in one of the following locations with clearance of 3.94 inches (100 mm) at
front and rear:
▪In a room or cupboard with volume of at least 4.38 ft3(0.124m3 ) or,
▪In a cupboard with volume of at least 4.38 ft3 (0.124m3), within a room that the pump serves, with
the top of the pump less than 2.62 ft (80cm) above finished floor level.
▪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.
•Additional clearance at the front and the rear of the pump should also be provided to accommodate the
connections.
•Sufficient space to install the controller in accordance with these installation instructions. The controller is 6.1
inches (155 mm) (height) by 1.6 inches (42 mm) (depth) by 6.1 inches (155 mm) (width).
•Ceiling heights are limited to 11.5 ft (3.5m) based on testing. Higher ceiling applications require the
involvement of a professional fire protection engineer at Plumis Inc.
•It is recommended that the controller is positioned near or next to the consumer unit. The controller should
also be installed in a location that 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 approved 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 1.6 gallons (6 litres) per minute flow at a minimum of 14.50 psi (1 bar)
(100kPa) and a maximum of 87.02 psi (6 bar) (0.6 MPa) static pressure. In case that pressure is too high, a
Plumis approved pressure reduction valve (pre-set to 43.51 psi (3 bar), maximum 232.06 psi (16 bar input)
shall be installed upstream of system water supply (available at the Plumis ordering shop). It is responsibility
of the installer to ensure the water supply to the Automist pumps is adequate. An outside pipe diameter of
less than 1.1 inches (28mm) is a good indicator that a survey is required.
•A dedicated electrical branch circuit. This should be on a listed and approved Overcurrent Protection Device
(Circuit Breaker) rated for 20 amps. This circuit breaker should protect only the Automist Smartscan Hydra
system and not be incorporated with any other circuit.
•All wiring and electrical safety shall comply with the National Electric Code and all local requirements.
•Important! If power cable can come into contact with parts having a temperature rise exceeding 122 F (50C),
the wiring insulation must be protected, for example, by insulating sleeving having an appropriate
temperature rating i.e. near boiler or hot water pipes.
•Important! The maximum allowable total data cable length for the spray heads daisy chain is 196.85 ft
(60m).
•Important! The maximum allowable total data cable length for the pump to the controller is 98.43 ft (30m).
•Important! The maximum allowable alarm cable length from spray head to the furthest connected wired
alarm is 98.43 ft (30m).
•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 3.93 ft (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.
