Introduction Thank you for purchasing a quality Mira product. To enjoy the full potential of your new product, please take time to read this guide thoroughly. Having done so, keep it handy for future reference. The Mira Escape Thermostatic is an electric shower with separate controls for power selection and temperature/flow adjustment. A unique thermostatic valve stabilises temperature changes caused by water pressure fluctuations. These can result from taps being turned on or off, or toilets being flushed.
Recommended Usage Domestic ü Light Commercial ü Heavy Commercial û Healthcare û Guarantee For domestic installations, Mira Showers guarantee the Mira Escape 9.0 kW and 9.8kW against any defect in materials or workmanship for a period of two years from the date of purchase (shower fittings for one year). For non-domestic installations, Mira Showers guarantee the Mira Escape 9.0 kW and 9.8kW against any defect in materials or workmanship for a period of one year from the date of purchase.
Important Safety Information WARNING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY: 1. Installation of this shower must be carried out in accordance with these instructions, and must be conducted by competent personnel. 2. Isolate the electrical and water supplies before commencing installation. The electricity must be switched off at the consumer unit and the appropriate circuit fuse removed, if applicable. 3.
16. Electric showers can deliver scalding temperatures if not operated, installed or maintained in accordance with the instructions, warnings and cautions contained in this guide and on or inside the shower. 17. Rapid or excessive operation of the shower controls may result in high or unstable outlet water temperatures. Operate controls gradually and allow 10-15 seconds to stabilise checking the temperature before entering the shower. 18.
Pack Contents Checklist Tick the appropriate boxes to familiarize yourself with the part names and to confirm that the parts are included.
Specifications 1. Plumbing • Minimum maintained inlet pressure for 9.0 kW and 9.8 kW 70 kPa (0.7 bar). • 100 kPa (1.0 bar) recommended for satisfactory operation. • Maximum static inlet pressure 1000 kPa (10 bar). • Minimum static pressure 20 kPa (0.2 bar) to keep the inlet valve closed. 2. Electrical • The Mira Escape 9.0 kW requires a 40 Amp fuse. The Mira Escape 9.8kW requires a 45 Amp fuse. • The terminal block will accept cable up to 16 mm².
• Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of the hose. • A Soap Dish/Hose Retaining Ring is supplied to prevent the handset from dropping below the spill-over level of the bath or shower tray, which could lead to contamination from back-siphoning. The supplied Hose Retaining Ring should meet the majority of user requirements for shower installations with flexible outlet fittings. However, there will be occasions when it will not provide a suitable solution.
2. Electrical • In a domestic installation, the rating of the electricity supplier’s fuse and the consumer unit must be adequate for the additional demand. All Mira electric showers are high power units, it is essential to contact your electricity supplier to ensure that the supply is adequate for the product. Voltage drop due to local heavy demand will reduce the shower’s performance. • The appliance must be earthed by connecting the supply-cable earth conductor to the earth terminal.
Consumer Unit Double-pole Isolating Switch Installation Installation of Mira Escape Warning! Turn off the electrical and water supplies before proceeding with the installation of the Mira Escape. The electricity must be turned off at the mains and the appropriate circuit fuse removed, if applicable. Note! An installation template is supplied to help you install the Mira Escape.

User Instructions How Your Electric Shower Works Heated water is produced by adjusting the flow of cold water passed through a heater tank. + LD CO _ The shower has three heater settings. + _ + _ The warmer the shower, the lower the flow rate and vice versa.
Thermostatic (Temperature-Stable) The shower's top priority is to keep the desired water temperature constant. Electric showers with thermostatic control are able to keep a stable temperature across the range from hot to cold, whilst also dealing with fluctuations in electrical and water supplies. As a result, there is a temperature limit the shower cannot go beyond. For safety, this temperature is factory set and cannot be adjusted to make the shower hotter or colder.
Using your Shower Read the section “Important Safety Information” first. 1. 2. Switch on electrical supply. 3. Press the ‘Start/Stop’ button, light on the button comes on. 4. + _ Set to desired position. 5. Check water temperature before entering shower. + _ Allow 10 - 15 seconds for any temperature adjustments to reach the handset. 6. 7. Press STOP button, light on the button goes out. Shower flow will continue for a few seconds before stopping. Isolate power.
The Effect of Seasonal Changes + _ For a cold shower select I. For a summer warm shower select II. For a winter warm shower select III. During extremes of mains water supply temperature, adjust heater setting to obtain a better showering temperature. The Effect of Other Water Devices Example of how shower temperature stabilises due to pressure changes. + _ ± 2°C Water inlet pressure fluctuations due to other draw offs (e.g. flushing toilet).
