Model 620 - Press button “C”. The electricity to the elements is then switched off, water will continue to flow for approximately 5 seconds before switching off. This reduces the temperature of the water in the unit.
Switch the electricity off at the ceiling switch or local isolator.
10.Your shower is designed to stabilise temperature changes caused by water pressure fluctuations. These can result from toilets being flushed or taps being turned on or off. When this happens your showering temperature will be held within a controlled band, provided that the minimum pressure required by the shower is maintained.
11.Your shower requires a minimum operating pressure of 100 kPa (1.0 bar, 14.5 p.s.i.). At pressures above 100 kPa (1.0 bar, 14.5 p.s.i.) it will minimise temperature fluctuations detailed in note 9. If the water pressure falls below 100 kPa (1.0 bar, 14.5 p.s.i.), it is likely that the pressure switch will turn off the power to the heating elements, resulting in a cold shower.
12.During normal operation if the shower senses an overheated water temperature then the thermal cutout will switch off the heating elements. Water will continue to flow and as the water temperature falls the heating elements will be turned back on. If the unit continues to do this then increase the flow rate by turning knob “B” clockwise and check that the handset does not require
13.Note that knob “B” IS NOT A TAP and does not turn the water off.
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 shower works
Your 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 heating tube.
2.The required water temperature is achieved by adjusting the rate of water flow. Diagram 2 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 mains can vary considerably
