Both Immersion Heaters [14,15], the Pump [3], Flow Switch [4], are pre-wired to the Wiring Centre [42], and are isolated from their appropriate electrical supply until the unit is full, switched via the Level Switch [55] and relays.
The Bleed Valve [56] is to be OPEN during filling to provide an indication of when the unit is full, and to remove excess water. The unit is fitted with an Integral Overflow Chamber [8], which traps small volumes of water discharged as a result of overfilling. Water in the chamber can be drained off via the Overfill Drain Cock [66]. The unit MUST be watched during filling as excessive overfilling will result in over-spill onto the floor.
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 -  mains water pipework  should be protected separately (either by draining or by the application of trace heating).
