How To Use Your Shower Your shower has two modes of operation, Normal and Temperature Lock. The temperature lock feature ensures a factory preset maximum temperature is not exceeded. [. . . ] The water is turned on and off by the solenoid valve built into the shower. A stabiliser is built into the flow valve to automatically compensate for small fluctuations in water pressure that frequently occur in households. There are three further controls to cater for exceptional reductions in water pressure to prevent the shower from getting too hot. a) If the flow of water is less than 1. 0 l/min the power to the elements is switched off, but the solenoid valve remains open allowing water to flow through the shower. b) If the outlet temperature sensor senses an excessive temperature the flow of water and the heating elements will automatically switch off. The electronics will signal over temperature condition (see "over temperature shutdown" section). c) A two stage mechanical thermal cut-out is mounted on the top of the heat exchanger independent of the electronics. Stage one switches the power off to the elements if it senses an excessive temperature. The switch operates with an audible click and will reset if cold water is run through the shower. Stage two only operates if an extreme temperature is sensed. The cut out will permanently switch off and it will then have to be replaced. A pressure relief device is fitted to safeguard against other extreme conditions. If this operates a replacement part will be required. 3. 4. 5. Troubleshooting If the performance of the shower deteriorates in service, follow the checks in the "self help" table opposite before calling out the contractor. Any one of the simple adjustments could restore the performance. If these fail to restore the performance you should seek professional help. The person who installed the shower is probably the best one to repair it and is certainly the person to contact if you have a problem in the guarantee period. 6 Self Help Check List a) Water too HOT Press the cooler button when in NORMAL operation. Press the warmer button when in NORMAL operation. Switch off electricity at ceiling / isolating switch, wait a few seconds, switch on again. (Note the shower should be switched off each time after use at the ceiling switch). Note: It there is no water flowing then the shower will automatically switch off after 30 seconds Check the water supply is turned on. Unit in over temperature mode see section on "purging" Check ceiling switch is on. [. . . ] Replace the front cover and fasten in position with three screws. d) Commissioning The unit is supplied in TEMPLOCK mode. It is recommended that the commissioning be carried out in NORMAL mode. Ensure the water and electricity are switched on to the unit. [. . . ]
