The key installation steps

 

1.

Preparing the site

  

 

 

Before installing ensure that the following have been provided at the installation site:

  • Sufficient space to install the pump. The pump is 385 mm (height) by 216 mm (length) by 151 mm (width) and weighs 11.2 kg.

  • A reliable cold water supply (6 lpm flow and 1 to 10 bar pressure) with a standard BSP 3/4” connection.

  • Automist should be powered by an independent circuit either via a delayed action RCD or no RCD (1.7kW, 230V and 50Hz) with an unswitched fused connection unit.

2.

Install the spray head

  

 

 

The Automist emitter can be installed either within a standard 35mm hole (under a tap or on a work surface), or wall mounted in a standard single-gang mounting box (85mm x 85mm with fixing centres offset centre to centre by 60mm) The nozzles must be installed between 600 -1100 mm from the ground and directed into the protected volume.

3.

Connect the water supply

 

 

 

Position the pump as close as possible to the mains water supply pipes. Connect the high pressure hose from the assembled emitter to the outlet on the pump. Connect the 3/4” water supply with an approved isolation valve to the check valve. Finally, connect the check valve outlet to the pump inlet.

4.

Connect the electrics

 

 

 

Connecting the power to the electrics requires a suitably qualified & competent person. Switch off electricity at the mains before working on existing circuits. Connect the wiring between the mains, control unit, pump and alarm detection system.

 

 

 

5.

Commission the unit

  

 

 

Commissioning is a procedure which allows Automist to be tested. During commissioning, the pump runs for approximately 20 seconds and the output pressure is monitored. A rubber shield is provided to direct the resulting spray into an adjacent sink or within a bucket.

System Diagram

Standard under tap installation:-

1. Automist emitter

- utilises watermist nozzles from the commercial fire fighting industry. Silicon protective caps protect the nozzles from limescale, dirt and cleaning products.

2. Automist Pluvia Pump

- water is driven by a positive displacement pump, powered by a 1.7 kW AC induction motor to deliver 5.3 lpm at 80bar.

3. High pressure hose

4. ¾" braided stainless steel hose

5. ¾" approved single check valve

6. Heat alarm

- sensing is based on heat detection as recommended in Approved Document B, effectively eliminating nuisance alarms.

Alternative installation:-

7. Automist wall mounted nozzle kit

- A standard single-gang mounting box holds the spray head in place and allows the system to become a stand alone side wall sprinkler. In this case the pump can be housed in a cupboard, under a staircase or within a custom box unit.
