Notes..
The Flow Switch is fitted with a 22mm By-Pass. This can be used to reduce the mains pressure drop across the unit. The valve should be balanced so that the Heat Exchanger Pump [3] switches on at the minimum hot water flow rate.
The unit is fitted with two heat exchangers, and is capable of delivering 45 litres/minute @45°C (80°C storage).
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. 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.
