Notes..
The Wiring Centre [42] is fitted with a neon which indicates when the unit needs re-filling. It is also fitted with a 5 amp relay to prevent the Heat Exchanger Pump [3] from activating - there will be no hot water available until the unit is topped up manually, using the filling loop [54].
The Bleed Valve [56] is to be used during filling to provide an indication of when the unit is full, and to remove excess water.
The Electronic 7 Controller is not suitable for a Dual Supply Tariff. Other controllers available to suit.
A Mains Water Isolating Lever Valve must be fitted within the cylinder cupboard, in clear view and easily accessible. A Strainer (supplied loose) must also be fitted, down stream of the isolating valve, to protect the flow switch [4].
It is advised that the mains water is tested for hardness. In areas of hard water, we advise the use of a scale inhibitor.
It is important that SENTINEL X100 Inhibitor is used to protect the Heat Bank Thermal Store.  Use 1 litre per 100 litres of stored water. Label the unit as protected with the label provided.
A suitable anti-freeze, such as X500, should also be added when there is a chance that the unit will be left filled and unheated in freezing conditions.
