Location
In general a Water-King unit should be installed as close as possible to the appliance where water is to be heated and scale is likely to form. This means in practice it should be installed on the cold service within the same plant room as the calorifier or water heater. If local electric water heaters are being used and especially when hot water draw-off is spare or spasmodic such as in an office environment, it is best to fit a dedicated unit such as the Sentry to each heater.

Signal Propagation
The signal generated by Water-King is transmitted through the water both upstream and downstream from the unit. This means that appliances and storage tanks upstream from the unit can be treated, although ideally water should pass the unit where practical.

Cold Water Storage Cisterns and Break Tanks
Vented cold water storage cisterns generally cause a discontinuity in the signal transmission resulting in decay of the clustering effect generated by the Water-King. This problem can be overcome by installing a unit on one of the outlet pipes from the cistern and utilising the “Back Signal” to treat the stored water. Where hot and cold tanks are close coupled, or there is no ready access to the outlet, the “Air Gap” can be bridged by installing a unit on the supply pipe and grounding one of the aerials to the tank. This procedure is fully explained in the installation instructions.

Booster Sets and Circulation Pumps
Water passing through a pump will lose the effect of Water-King treatment. A unit should be fitted on the discharge side of booster sets and circulation pumps.

Hot Water Secondary Return (HWSR)
We recommend that the HWSR should be treated with a Water-King between the circulation pump and the calorifier or water heater.

Heat Exchangers
We recommend that both the cold inlet and the heated discharge of Plate and Frame or Shell and Tube heat exchangers are treated. This is more easily achieved with any of the four aerial units by applying one pair of aerials to each of the inlet and discharge pipes. Where a pump is close coupled to the inlet side of a heat exchanger, treat only the outlet pipe.

Blending Valves and Showers
Most of the scale formed in these fittings is precipitated from the cold water. It is essential that the cold water services to these appliances are treated as well as the hot.

Re-Circulating Systems
Where water is being constantly circulated, such as through a cooling tower, the Water-King unit should be fitted on the circulating system downstream from the pump and as close as possible to where the heating process or pressure drop is occurring. There is no need to treat the make up water.

Low Water Content Finned Type Water Heaters
Generally this type of water heater is highly resistant to scaling but, to protect buffer vessels and other downstream appliances, we recommend treatment of the return to the buffer at a point after the HWSR and make up water.
