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 Play 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.

Plumbing (checklist in detail) 1. The appliance is designed to operate with a minimum maintained inlet pressure of 70 kPa (0.7 bar), up to a maximum static inlet pressure of 1000 kPa (10 bar). 2. When installed in very hard water areas (above 200 ppm temporary hardness) your installer may advise the installation of a water treatment device, to reduce the effects of limescale formation. Your local water company will be able to advise the hardness of water in your area. 3.
Read the section “Important Safety Information” first. Electrical Checklist 1. Electrical supply fuse and consumer unit are adequate for the product. 2. Shower unit is earthed. 3. The minimum required supply cable size must conform to BS 7671. 4. Double pole isolating switch. 5. DO NOT twist live or neutral cable cores. 6. Electrical connections are tightly secured. DO NOT strain the terminal block. 7. Plumbing supply completed before electricity supply is turned on.
Electrical (checklist in detail) 1. 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 Play electric showers are high power units, therefore 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. 2.

How Your Electric Shower Works Hot water is produced by passing cold water through a heating tank. + LD CO _ The shower has three heater settings. + _ + _ 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. The Effect of Other Water Devices Example of how shower temperature stabilizes due to sudden pressure changes.
Using Your Shower Read the section “Important Safety Information” first. 1. 2. PUSH Switch on electrical supply. 3. Press START button. 4. + _ Set to desired position. Check water temperature before entering shower. 5. + _ Allow 10-15 seconds for any temperature adjustments to reach the handset. 6. 7. PUSH A small amount of water may continue to drain over a few minutes. Press STOP button. Shower will continue to run for a few seconds before stopping.
Changing the Spray Setting The handset has three different spray settings (Start, Soothe and Force). 1. 2. Start Turn the Spray Plate anticlockwise until it “clicks”. Water will flow from the outer set of holes. Soothe Turn the Spray Plate anticlockwise until it “clicks”. Water will flow from the large diameter 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! Symptom Power Light Heater Setting Low/ Medium/ High Probable Cause Possible Remedy Shower is too hot during the summer.
Symptom Power Light Heater Setting Low/ Medium/ High Probable Cause Possible Remedy ON Any The incoming water supply stop valves, or the appliance isolating valve, is closed. Open the stop/isolating valve fully. ON Any Handset blocked. Remove and clean. For sprayplate cleaning, refer to the Handset manual. OFF Any The fuse is blown or the MCB/RCD has been tripped, indicating a possible electrical fault. Renew the fuse or reset the MCB/RCD. If the fault persists, contact the shower installer.
Symptom Power Light ON Heater Setting Low/ Medium/ High Probable Cause Possible Remedy Medium/ High 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 Control anticlockwise to reduce the water temperature. DO NOT TAMPER with the Thermal Switch. ALL OF THE FOLLOWING REMEDIES MUST ONLY BE PERFORMED BY A COMPETENT TRADESPERSON! No hot water from the shower, with controls in any position.
Symptom Power Light No water, or very low flow rate. Water leaks from the bottom of the case near the outlet. There is no flow from the outlet. Heater Setting Low/ Medium/ High Probable Cause Possible Remedy ON Any Handset blocked. Remove and clean. ON Any The incoming water supply stop valves, or the appliance isolating valve, is closed. Open the stop/isolating valve fully. ON Any Insufficient mains water pressure. Check the integrity of the internal wiring.
Symptom Power Light The water cannot be turned off. Heater Setting Low/ Medium/ High Probable Cause Possible Remedy When the Relief Valve operates, a small rubber ball is ejected. Reset the Relief Valve assembly. See “Maintenance” section. OFF Any The Pilot Valve is faulty. Replace. OFF Any The diaphragm is damaged. Replace the Flow Valve assembly. OFF Any The supply pressure is below the minimum requirement. Contact local water company. Check the static water pressure.
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.
