The BCS1 pipeline set is a kit of components selected to enable

straightforward installation of a TDS control system where the probe

assembly is to be mounted in the pipeline, rather than directly in

the boiler shell.

The BCS1 pipeline set consists of the following items:-

1 x S10 sensor chamber 1⁄2" BSP.

1 x CP10 sensor and gasket.

1 x PT2 plug tail.

1 x Sensor chamber plug 1⁄4" BSP.

1 x BCV1 solenoid valve 1⁄2" BSP, 230 V.

1 x LCV1 check valve 1⁄2" BSP.

1 x Fig 12 SG iron strainer 1⁄2" BSP.

2 x M10 ball valves 1⁄2" BSP.

Alternative products are available, but not as part of a kit.

A controller is also required, and should be selected from the Spirax

Sarco range.

The BC3150 and BC3250 are both suitable, and offer a choice of

features. Full details are available in separate literature.
