SHOWERS, BIDETS, TAPS AND MIXING
VALVES
Standard hot and cold taps and mixing valves used with the
appliance must be suitable for operating at the available mains
pressure. 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.

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.
