The Mira Advance ATL manual emphasizes safe connection procedures. For water, connect to the mains cold water supply using appropriate plumbing fittings, ensuring compliance with regulations. The manual details correct inlet pressure requirements. Electrical connection must be carried out by a qualified electrician, adhering to wiring diagrams within the manual.
Ensure the electrical supply matches the shower’s power rating (9.0kW or 9.8kW). Proper earthing is critical for safety, as highlighted in the manual. Isolate the electrical supply before commencing any wiring. Double-check all connections for security and watertight integrity, following the manual’s guidance.

Operating the Mira Advance ATL
The manual guides users through powering on, initial setup, and temperature adjustment. Utilize the temperature limit stop for enhanced safety, as detailed in the manual.
Powering On and Initial Setup
Before your first use of the Mira Advance ATL, carefully consult the manual for crucial safety information. Ensure the electrical supply is correctly connected and switched on, adhering to all electrical safety guidelines outlined within. Upon initial power-up, the shower may take a moment to prime; this is normal.
The manual details how to perform a pre-shower check, verifying water flow and temperature control functionality. Familiarize yourself with the shower’s controls – power button, temperature adjustment, and any additional features specific to your model (Standard, Extra, or Flex Extra). It’s recommended to initially set a lower temperature and gradually increase it to your desired comfort level, always testing the water temperature before fully entering the shower.
Refer to the manual for specific instructions regarding the temperature limit stop and how to adjust it to prevent scalding.
Adjusting Water Temperature
The Mira Advance ATL’s manual emphasizes precise temperature control via the shower’s dial. Rotate the dial clockwise to increase the water temperature and counter-clockwise to decrease it. The thermostatic valve maintains a consistent temperature, minimizing fluctuations during your shower.
The manual advises starting with a lower temperature and gradually adjusting it to your preference, always testing the water before fully entering. Be mindful of the temperature limit stop; it prevents excessively hot water. If the water isn’t reaching your desired temperature, check the incoming water supply temperature and ensure sufficient water pressure.
Consult the manual for troubleshooting temperature inconsistencies and understanding the shower’s response to changes in water pressure.
Using the Temperature Limit Stop
The Mira Advance ATL manual highlights the crucial safety feature: the temperature limit stop. This adjustable mechanism prevents water from exceeding a pre-set maximum temperature, safeguarding against scalding. Located on the shower unit, it’s typically adjusted using a small tool or screwdriver, as detailed in the manual.
The manual recommends setting a comfortable maximum temperature, especially when children or vulnerable individuals use the shower. Regularly check the limit stop’s setting to ensure it remains appropriate. Adjusting it involves loosening a screw, moving the slider to the desired temperature, and re-tightening the screw.
Always refer to the manual for specific instructions and diagrams related to your ATL model.

Troubleshooting Common Issues
The Mira Advance ATL manual suggests resetting the unit by cutting power. For persistent problems, like cold/hot water, contact Mira customer support immediately.
Low Water Pressure Problems
If experiencing low water pressure with your Mira Advance ATL, consult the official manual first. Check that the inlet filter isn’t blocked, as debris can significantly reduce flow. Ensure the shower is connected to a mains-fed cold water system with adequate pressure – the manual specifies the required range.
Verify that other taps in your home aren’t simultaneously drawing large amounts of water, which could lower pressure to the shower. A partially open stop valve on the shower’s inlet pipe can also restrict flow. If the problem persists after these checks, the pump (for low-pressure models) might be malfunctioning, requiring professional attention. Always refer to the manual for specific troubleshooting steps related to your model.
Temperature Fluctuations
Temperature instability in your Mira Advance ATL often indicates issues with the thermostatic valve. The manual advises checking for limescale buildup, as this disrupts accurate temperature regulation. Descaling the valve, as detailed in the maintenance section of the manual, is crucial.
Fluctuations can also occur if the temperature limit stop is set too close to the desired temperature; adjust it slightly. Ensure consistent cold water supply – simultaneous use of other hot water appliances can cause dips. If problems continue, the thermostatic cartridge itself might be faulty, necessitating replacement. Always consult the manual before attempting any repairs, and prioritize safety.
Shower Not Turning On
If your Mira Advance ATL fails to power on, the manual suggests first verifying the electrical supply. Check the circuit breaker hasn’t tripped and that the shower’s power cable is securely connected. A complete reset – switching off the electrics for 30 minutes – is recommended, as outlined in troubleshooting guides within the manual.
Inspect the shower’s internal fuse; a blown fuse will prevent operation. If these steps don’t resolve the issue, the problem may lie within the shower’s control unit. Contacting Mira customer support, as detailed in the manual’s warranty section, is advised for more complex issues or potential repairs.
Maintenance and Care
Regular cleaning of the showerhead and descaling the thermostatic valve, per the manual, ensures optimal performance. Inspect components routinely for wear.
Cleaning the Shower Head
Maintaining a clean shower head is crucial for consistent water flow and a pleasant showering experience with your Mira Advance ATL. Over time, limescale and mineral deposits can build up, restricting water pressure and potentially damaging the shower head itself. The manual recommends regular cleaning, ideally monthly, depending on water hardness.
To clean, gently remove the shower head (consult the manual for specific instructions for your model). Soak it in a solution of white vinegar and water – a 50/50 mix is effective – for at least 30 minutes, or even overnight for stubborn deposits. Use a soft brush, like an old toothbrush, to scrub away any remaining limescale. Rinse thoroughly with clean water before reattaching. Avoid abrasive cleaners, as these can scratch the surface and damage the finish.
Regular cleaning will prolong the life of your shower head and ensure optimal performance.
Descaling the Thermostatic Valve
Descaling the Mira Advance ATL’s thermostatic valve is vital for maintaining accurate temperature control and preventing malfunctions. Limescale buildup can impede the valve’s operation, leading to inconsistent water temperatures or even complete failure. The manual advises descaling frequency based on water hardness – more often in hard water areas.
Refer to your manual for specific descaling instructions, as procedures vary slightly between models. Generally, this involves isolating the water supply, partially disassembling the valve (following the manual’s guidance precisely), and flushing it with a descaling solution. A commercially available descaler designed for showers is recommended.
Thoroughly rinse the valve with clean water after descaling to remove all traces of the solution before reassembling and restoring the water supply.
Regular Inspection of Components
The Mira Advance ATL manual stresses the importance of routine component checks for longevity and safety. Regularly inspect the shower head for limescale buildup and blockages, cleaning as needed. Examine the hose for kinks, cracks, or leaks, replacing it if damaged.
Crucially, check the thermostatic valve for any signs of corrosion or wear. Ensure all connections are tight and free from leaks. The manual details how to access and inspect key components. Pay attention to the turbine and connector assembly, as highlighted in installation guides.
Proactive inspection, guided by the manual, can identify potential issues before they escalate, saving on repair costs and ensuring continued safe operation.
