[. . . ] Failure to install appliances correctly could lead to prosecution. It is in your interest and that of safety to ensure compliance with the law. The manufacturers notes must not be taken, in any way, as over-riding statutory obligations. WARNING: This appliance must be earthed and protected by a 3 amp fuse. [. . . ] Thermostatically controlled or pressure equalising shower valves will guard against the flow of water at too high a temperature. Hot and cold mains fed water can be supplied direct to an overrim flushing bidet subject to local water company requirements. With all mains fed systems the flow of water from the individual taps will vary with the number of outlets operated simultaneously and the cold water mains supply pressure to the property. Flow balancing using `Ball-o-Fix' type valves is recommended to avoid an excessive reduction in flow to individual outlets. For further information contact Worcester Heat Systems Ltd. HOT AND COLD FLOW If the flow of water demanded from both hot and cold service outlets is dependent upon mains supply, it may not be possible in some installations to operate all outlets simultaneously. WATER MAINS FAILURE It is important to note that in the event of a mains water supply failure, no tap water will be available until the mains supply is restored. USE IN HARD WATER AREAS In temporary hard water areas (more than 350mg/litre or 200ppm calcium bicarbonate) it is recommended that a proprietary scale reducer is fitted in the mains cold water connection to the appliance. Consult the local water company for additional advice. Installation of a scale inhibitor assembly should be in accordance with the requirements of the local water company. An isolating valve should be fitted to allow servicing. The water hardness can be determined by reference to the local water company. DOMESTIC HOT WATER TEMPERATURE CONTROL By slightly reducing the flow of domestic water from the tap, the delivery temperature will be increased. This is of particular advantage in the winter, for example to increase bath water temperature and to remove heavy grease deposits on plates, etc. Also this will provide an added advantage of reducing the delay before hot water is obtained. 6 VENTILATION OF THE APPLIANCE This is a room sealed appliancem, any ventilation openings in a wall or door must not be obstructed.
