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 Wiring & Control Centre [42] is fitted with the following warning lights:
a) Over-Heat, b) Over-Flow, c) Low Water Level
An Audible Alarm is sounded during Over-Flow conditions. |
| The Wiring & Control Centre [42] provides wiring to all fitted controls, as well as terminals for installer connections to electrical supplies:
a) 3amp supply to Flow Switch [4], Pump [3] & Water Level Cutout
[55], b) 25amp supply to upper Immersion Heaters,
c) Connections to remote Immersion Heater Switch, such as a time clock,
d) Connections to remote Alarm. |
| 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. |
| A chemical corrosion inhibitor, such as
Sentinel X100, must be added to the stored water within the cylinder. Anti-freeze should also be added where there is a possibility of prolonged exposure to sub-zero temperatures.
