The document provides an installation and user guide for the GROHE Tempesta 100 Electric Shower, a product designed and engineered in Germany. It includes important safety information, installation instructions, advice for users, maintenance tips, troubleshooting, and a description of how the shower works, along with a list of common spare parts and a circuit diagram.
The GROHE Tempesta 100 Electric Shower is designed to provide instantaneous hot water for showering. It heats mains cold water as it flows over electric heating elements within a heat exchanger. The shower is designed to stabilize temperature changes caused by water pressure fluctuations, ensuring a consistent showering experience. A pressure switch automatically activates the heaters only when sufficient water is flowing. The water flow is controlled by a solenoid valve, which is switched on and off by a start/stop button. For safety, a thermal cut-out switches off power if the water temperature exceeds a set limit, and a pressure relief device safeguards against abnormal pressure conditions, preventing excessive pressure build-up within the unit. The shower is intended for permanent connection to the fixed electrical wiring of the mains supply with its own dedicated supply and must be earthed.
The shower features two control knobs and a push-button for operation. Knob 'A' controls the power selection, offering three settings: 'I' (1 bar), 'II' (2 bars), and 'III' (3 bars). Knob 'B' controls the water temperature. The push-button 'C' starts and stops the shower. To begin showering, the user presses button 'C', which illuminates the 'Power' light and initiates water flow. The desired power setting can then be selected, typically 'III'. The water temperature is adjusted by turning Knob 'B': anti-clockwise for cooler water and clockwise for warmer water. It is recommended to allow about 20 seconds for the water temperature to stabilize after adjustments. The shower is designed with a multi-spray pattern handset, allowing users to adjust spray patterns by rotating the spray plate, with each mode identified by an audible click. The unit includes an 'Auto Reset' light that illuminates if the water temperature becomes overheated, indicating that the heater has temporarily switched off. Water will continue to flow and cool down before the heater reactivates.
Regular maintenance is crucial for the shower's performance and longevity. The guide emphasizes that the shower unit and accessories should be cleaned using a soft cloth, avoiding abrasive or solvent-based cleaning fluids, especially on plated finishes. Before cleaning, the isolating switch should be turned off to prevent accidental activation. The shower handset requires regular cleaning to prevent limescale build-up, which can reduce performance. This can be done by rubbing the rubber nozzles or soaking the handset in a proprietary limescale remover and rinsing thoroughly. The inlet filter, located inside the water inlet fitting, can also be cleaned to maintain performance. Accessing the filter requires removing the front cover and the detachable lower section of the backplate, then unscrewing the filter cap. When cleaning the filter, a sharp object should not be used to avoid damage; an old toothbrush is suggested. The metal filter mesh is best cleaned while still in the cap. The shower hose should be regularly inspected for wear and damage and replaced every two years or if necessary, with an approved part. The guide also provides a troubleshooting section for common issues, such as water being too hot or cold, water taking longer to heat up, water going cold during use, poor spray, or broken parts, offering self-help checks before professional service is required.
