Any regulations specified by the local water company must be observed. The final 600 mm of the mains cold water connection to the applaince should be made in copper tube only. The appliance is suitable for a mains supply having a maximum pressure of 10 bar. A pressure reducing valve must be fitted, if necessary. The hot water outlet temperature is set to be capable of achieving a maximum of 60 °C. The maximum temperature and the frequency of the recharge of the heat store may be reset. The maximum water flow rate is factory set at 9.9 l/min to give temperature rise of 40 °C. If a higher rise is required then the flow must be reduced at the tap and the discharge temperature will rise up to the maximum set figure.
The temperature rise, upto the maximum set by the user, is automatically maintained by the modulation of the heat input. In winter, when the mains temperature is very low, the water flow, adjusted at the tap or shower, should be reduced to maintain the required delivery temperature.
