USER INSTRUCTIONS

How Your Electric Shower Works

Heated water is produced by adjusting the ow of cold water passed through a

heater tank.

The temperature indicator shows the temperature of the shower.

The shower has three heater settings.

The warmer the shower, the lower

the ow rate and vice

versa.

Page 18

Thermostatic (Temperature-Stable)

The shower's top priority is to keep the desired water temperature constant. Electric showers with thermostatic control are able to keep a stable temperature across the

range from hot to cold, whilst also dealing with uctuations in electrical and water supplies. As a result, there is a temperature limit the shower cannot go beyond. For

safety, this temperature is factory set and cannot be adjusted to make the shower hotter or colder.

The Effect of Seasonal Changes

For a cold shower select ‘Low’. For a summer warm shower select ‘Medium’. For a winter warm shower select ‘High’.

During extremes of mains water supply temperature, adjust heater setting to obtain a better showering temperature.

The Effect of Other Water Devices

Example of how shower temperature stabilises due to pressure changes.

Water inlet pressure uctuations due to other draw offs (e.g. ushing toilet). Shower

temperature will be controlled to within ± 2°C of the set temperature provided that the supply conditions remain within the required operating parameters (refer to section: ‘Specications’).
