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 Elevate is an electric shower with separate controls for power selection and temperature/flow adjustment. A unique flow regulator stabilizes temperature changes caused by water pressure fluctuations. These can result from taps being turned on or off, or toilets being flushed.
Safety : Warnings 1.Warning! 1.1. This shower 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 appliance. 1.2. THIS APPLIANCE MUST BE EARTHED. MAKE SURE SUPPLEMENTARY BONDING COMPLIES WITH THE “REQUIREMENTS FOR ELECTRICAL INSTALLATIONS”. The installation must be in accordance with the current edition of BS 7671 “The IEE Wiring Regulations” in force at the time of installation.
2.3. The plumbing installation must comply with the requirements of UK Water Regulations/Bye-laws (Scotland), Building Regulations or any particular regulations and practices, specified by the local water company. The installation should be carried out by a plumber or contractor who is registered, or is a member of, an association such as: 2.3.1. Institute of Plumbing (IOP), throughout the UK. 2.3.2.
Pack Contents Tick the appropriate boxes to familiarize yourself with the part names and to confirm that the parts are included.
Specifications 1. Plumbing 1.1. Minimum maintained inlet pressure: 9.5 kW = 70 kPa (0.7 bar) 10.8 kW = 100 kPa (1 bar) 1.2. Maximum static inlet pressure of 1000 kPa (10 bar). 1.3. Minimum static inlet pressure of 50 kPa (0.5 bar) to keep the inlet valve closed. 2. Electrical 2.1. The Mira Elevate 9.5 kW requires a 40 Amp circuit protection device. The Mira Elevate 10.8 kW requires a 45 Amp circuit protection device. 2.2. The terminal block will accept cable sizes up to 16 mm2. 3.
4. The appliance must be fitted onto a finished flat and even wall surface (this wall surface should be tiled or suitably waterproofed). Do not fit the appliance to the wall and tile up to the case. For safety requirements, an air gap must be left behind the appliance. 5. Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of the hose. 6. Supply pipework must be flushed to clear any debris before connecting to the appliance. 7.
4. As a guide only, and in accordance with BS 7671 we recommend close circuit protection: i.e. 9.5 kW = 40 Amp, 10.8 kW = 45 Amp. It is strongly recommended that a 30 mA Residual Current Device (RCD) is included in the electrical circuit. This may be part of the consumer unit or a separate unit. A separate, permanently connected supply is taken from the consumer unit to the appliance through a double pole isolating switch, which has at least 3 mm of contact separation.
Installation Warning! Turn off the electrical and water supplies before proceeding with the installation of the Mira Elevate. The electricity must be turned off at the mains and the appropriate circuit fuse removed, if applicable. 1. Hold the installation template in the required position on the wall and mark the positions of the fixing holes. Make sure that there is adequate clearance available for the slide bar.
Cover Fixing Screws 5. Remove the four screws that attach the cover assembly. Remove the cover assembly and place to one side. Cover Assembly 6. Fit the shower to the wall with the supplied fixing screws.
7. Remove the service tunnel. 8. Connect the water supply to the inlet connector assembly. Do not overtighten. Inlet Connector Assembly Water Supply 9. Feed the electrical cable into the case. Fit earth sleeve (not supplied) and strip insulation. Do not twist cable cores. 10. Firmly connect the conductors. Do not exert strain on the terminal block.
11. Fit the wall bracket into the top bracket of the slide bar. Sticky Pad Top Bracket 12. Remove the backing from the sticky pad on the rear of the wall bracket. 13. Fit the front cover of the shower onto the backcase. With the front cover pushed fully into place, apply a small amount of pressure to the top bracket. This will allow the sticky pad to hold the wall bracket in position ready for marking the position of the fixing holes. Wall Bracket 14.
Note! The soap dish is an accessory and does not have to be fitted. If you do not fit the soap dish, then fit the screw (supplied with the soap dish clamp) to secure the cover in position. 19. Screw the soap dish clamp onto the bottom of the case. 20. Slide the soap dish over the clamp making sure that the lip on the soap dish locates correctly on the bottom bracket. Soap Dish Clamp Soap Dish 21. Connect the flexible hose to the handset making sure that the hose washer is in position. Do not overtighten.

How Your Electric Shower Works Power Setting Low, Med, High Heater Tank Assembly Heating Elements within heat cold water as it passes over them. Temperature Control Adjust water flow to increase or decrease temperature. Cold Mains Water Inlet Warm Water to Shower Outlet Hot water is produced by passing cold water through a heating tank. + LD CO _ The shower has three settings, LOW, MEDIUM and HIGH. + _ + _ The warmer the shower, the lower the flow rate and vice versa.
The Effect of Seasonal Changes + * ** _ For a cold shower select Low . For a summer warm shower select Medium . For a winter warm shower select High . During extremes of mains water supply temperature, adjust heater setting to obtain a better showering temperature.

Using Your Shower Read the section “Important Safety Information” first. 1. 3. 2. Switch on electrical supply. 4. Press START button. + _ 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. A small amount of water may continue to drain over a few minutes. Press STOP button.
Changing the Spray Setting The handset spray head has four different spray actions:- Eco, Start, Soothe and Force. The handset operation is described below. 1. Eco To access the eco setting, turn the spray plate fully clockwise.Water will flow from the outer set of holes and the flow rate will be reduced. 2. Start To access the start setting turn the spray plate anticlockwise until it ‘clicks’ (one click from the eco setting). Water will flow from the outer set of holes. 3.
Fault Diagnosis The trouble shooting information table below gives details on probable causes and remedies should difficulties be encountered whilst the shower is in operation. Warning! There are no user serviceable components beneath the cover of the appliance. ONLY A COMPETENT TRADESPERSON SHOULD REMOVE THE FRONT COVER! Malfunction Cause Remedy Shower is too hot during the summer. The incoming water is warmer in the summer, so the shower power setting is too high.
Malfunction Cause Remedy Temperature cycles between hot and cold. The temperature is set too high. This is causing the thermal switch to turn off the heating element to reduce the water temperature. Turn the temperature knob anticlockwise to reduce the water temperature. ALL OF THE FOLLOWING REMEDIES MUST ONLY BE PERFORMED BY A COMPETENT TRADESPERSON! Malfunction Cause Remedy No hot water form Insufficient water supply shower, with the knobs in pressure. any position.
Malfunction Cause Remedy No water or very low flow The handset sprayplate rate. is blocked. The incoming water supply stop valves, or the appliance isolating valve is closed. The hose or handset is blocked. Insufficient water supply pressure. The heater tank is excessively scaled. The pilot valve is faulty. Water leaks from the bottom of the case near the outlet, and there is no flow from the handset. Clean the handset sprayplate. Open the stop/isolating valve completely.
Malfunction Cause Remedy The water cannot be turned off. The pilot valve is faulty. Replace the flow regulator assembly. Replace the flow regulator assembly. Contact the local water authority. The supply pressure is below the minimum requirement.
Maintenance Handset - Cleaning Clean with mild washing up detergent or soap solution. Wipe dry with soft cloth. R EA CL Poor shower performance can be avoided by cleaning the spray head. Use thumb or soft cloth to wipe rubber nozzles. The handset must also be descaled regularly.
