the option of reduced water flow. This option is mainly for summer usage and if this is used then knob 'B' must be re-adjusted.

8.When you have finished showering turn knob 'B' fully clockwise to the '• Stop' position. The motor will switch off and water will stop flowing. The 'POWER ON' light will also switch off.

9.Switch off the electricity at the ceiling switch or local isolator.

10.During normal operation if an overheated water temperature is sensed by the shower the thermal cut-out will switch off the power to the heating elements. The 'overheat' light will illuminate to provide a visual indication that this has taken place. Water will continue to flow and as the water temperature falls the heating elements will be switched back on. If the 'overheat' light continues to cycle turn knob 'B' anti-clockwise to a lower number on the temperature scale and check that the handset does not require de-scaling (see page 4). If the 'overheat' light still continues to cycle turn knob 'A' to the '• low power' setting (knob 'B' will need adjusting).

If the shower is operated after it has recently been used the 'overheat' light may illuminate for a few seconds. This indicates there is still some hot water left in the shower. Either, wait a few moments for the light to go out or turn

knob 'B' anti-clockwise to a lower number on the temperature scale.

WARNING! DO NOT SWITCH THE SHOWER ON IF YOU SUSPECT IT OF BEING FROZEN. WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.

HOW YOUR 'REDRING' SHOWER WORKS

Your Redring shower is designed for convenience, economy and safety of use.

1.Water is heated instantaneously as it flows over the heating elements in the copper cylinder assembly.

2.The required

water temperature is achieved

by adjusting the rate of water flow. Diagram 3 shows the principle involved in relating

temperature rise to flow rate. The higher the water flow the lower the temperature rise and vice versa. The temperature of the water supplied from the cold water storage cistern can vary considerably throughout the year from as low as 5º to as high as 30ºC. This means that in the winter, the flow rate will be less than in the summer to achieve the same outlet temperature. In summer the '• low power' setting may give adequate hot water.

3.Your shower incorporates a pump which boosts the incoming water pressure to a level more suitable for showering. The motor is controlled by a switch connected to knob 'B'.

4.The heaters are only switched on when sufficient water is flowing. This will happen when the motor is switched on, and is done automatically with a switch which works on water pressure.

5.The water is turned on and off by a tap that is built into the shower.

6.If the water supply falls below a set limit, the pressure switch will operate and switch off the power to the elements.

7.As a further safeguard, a thermal cut-out switches the power off if the water
