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 Azora is a thermostatic electric shower with separate controls for power selection and temperature/flow adjustment. A unique thermostatic valve stabilizes temperature changes caused by water pressure fluctuations. These can result from taps being turned on or off, or a toilet being flushed.

Minimum static pressure 20 kPa (0.2 bar) to keep the inlet valve closed. 2. Electrical The Mira Azora 9.8 kW requires a 45 Amp fuse. The terminal block will accept cable up to 16 mm2 . 3. Standards and Approvals The Mira Azora complies with all relevant directives for CE marking. Installation Requirements 1.
Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of the hose. A 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 1 Installation of Mira Azora Warning! Turn off the electrical and water supplies before proceeding with the installation of the Mira Azora. 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 Azora. Cover Retaining Screw Remove the three cover retaining screws and the cover. Caution! Handle glass cover assembly with care.
Determine the direction of the inlet water supply: top (falling), bottom (rising), or back inlet . Note! Make sure that the back inlet does not go directly back into the wall. Use a soldered elbow. Swivel the inlet connector assembly to suit. Remove the inlet blanking cap. Avoid trapping the green earth bonding wire. Before fitting the Cover, make sure that the appropriate cutouts have been removed to suit the supply entering the product. Thoroughly flush the mains-fed cold water supply pipe.
Feed cable into Case. Fit Earth sleeve (not supplied) and then strip insulation. Do not twist cable cores. L = BROWN E = GREEN/YELLOW Firmly connect the conductors. Do not exert strain on the terminal block. N = BLUE Cover Retaining Screw Refit the Cover, making sure it is correctly located. Do not overtighten screws. Caution! Handle glass cover assembly with care. Do not use alternative screws to secure the Cover. This can cause internal damage to the appliance.

2 Installation of Shower Fittings Decide on a suitable position for the slide bar avoiding buried cables and pipes. Drill the two 7.0 mm fixing holes for the slidebar at 600 mm centres and insert the wall plugs. Assemble the clamp bracket components. Push the plastic slidebar ends into the slidebar. Push the slidebar through the clamp bracket assembly, soapdish and hose retaining ring. Fit the bottom end support loosely to the wall. This will make aligning the top support easier.
