Notes..
The Wiring Centre [42] is fitted with a neon which indicates when the unit needs topping-up. It is also fitted with a 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 [8].
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.
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. 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.
