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. An individual light indicates “POWER ON”.

This shower comes complete with a set of Mira Response Adjustable Shower Fittings.

Mira Play models covered by this guide:

Mira Play 9.5 kW- A 9.5 kW 240 V AC (8.3 kW 230 V AC) heater. Available in white/ white panel, white/chrome panel and satin/chrome panel finishes.

Mira Shower Fittings covered by this guide:

Mira Response Adjustable Shower Fittings

An adjustable spray handset with three different spray actions (start, soothe and force), supplied complete with flexible hose, clamp bracket assembly, slide bar, supports, soap dish, and hose retaining ring. Available in white/chrome finish.

If you experience any difficulty with the installation or operation of your new shower control, then please refer to the Fault Diagnosis section before contacting Kohler Mira

Ltd. Our telephone and fax numbers can be found on the back cover of this guide.

Important Safety Information

1.Warning!

1.1. Products manufactured by us are safe and without risk provided they are installed, used and maintained in good working order in accordance with our instructions and recommendations.

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. This appliance is intended to be permanently connected to the fixed electrical wiring of the mains system with its own dedicated supply.

1.3. DO NOT twist the individual cable cores of the live and neutral conductors, as this will prevent them from entering the terminal block.

1.4. The shower unit must NOT be fitted where it may be exposed to freezing conditions.

Make sure that any pipework that could become frozen is properly insulated.

1.5. DO NOT fit any form of outlet flow control as the outlet acts as a vent for the tank body. Only Mira recommended outlet fittings should be used.

1.6. If the cover is removed, the following warnings must be observed:

1.6.1.Turn off the electrical and water supplies before removing the cover.

1.6.2.Mains connections are exposed when cover is removed.

1.6.3.Refer to the wiring diagram before making any electrical connections (see section “Wiring Diagram”).

1.6.4.Ensure all electrical connections are tight, to prevent them overheating.

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.

It is recommended that a non-restrictive (free flowing) isolating valve is fitted as part of the cold water supply pipe to allow the complete maintenance of the appliance. Do not use a valve with a loose washer plate (jumper) as this can lead to the build up of static pressure.

4.

The appliance is only suitable for installation within the shower area. It is fitted with a pressure relief device and must be positioned over a water catchment area with the controls at a convenient height for all users.

5.

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.

6.

Avoid layouts where the shower hose will be sharply kinked. This may reduce the life of the hose.

7.

A Hose Retaining Ring is supplied to prevent the handset from dropping below the spillover level of the bath or shower tray, which could lead to contamination from backsiphoning. The supplied Hose Retaining Ring should meet the greater majority of user requirements for shower installations with flexible outlet fittings. However, there will be occasions where it will not provide a suitable solution. In these instances an outlet double checkvalve, e.g. a Mira DCV-H, must be fitted. This will increase the required supply pressure typically by 10 kPa (0.1 bar). See section “Accessories”.

8.

Supply pipework must be flushed to clear any debris before connecting to the appliance.

9.

To avoid damage to the case when soldered fittings are used, pre-solder the pipework and fittings before connecting them to the inlet connector assembly. Refrain from applying excessive force when making any connections. Always provide mechanical support when making the plumbing connections.

10. The appliance is fitted with a plastic inlet compression assembly for connecting to a

15mm supply pipe from the top, bottom or back. Double checkvalves, fitted in the inlet supply to the appliance, cause a pressure build-up, which could exceed the maximum static inlet pressure and damage the appliance.

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.

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.

The appliance must be earthed by connecting the supply cable’s earth conductor to the earth terminal.

Supplementary bonding: Within the bathroom or shower room, all accessible conductive parts of electrical equipment and extraneous conductive parts (metal parts) that are likely to introduce earth potential, must be electrically bonded to earth. If the cable is not mechanically protected, the cable size must be a minimum of 4.0 mm 2 (2.5 mm 2 if mechanically protected). Use a suitable earth bonding strap to connect the earth terminal to 15mm copper pipe. The installation must comply with the “REQUIREMENTS

FOR ELECTRICAL INSTALLATIONS” in accordance with BS 7671.

3.

Supply cable - see opposite.

Important! The shower circuit should be separated from other circuits by at least twice the diameter of the cable or conduit, and it should not be run through thermally insulating material or in locations where the ambient temperature is likely to exceed 30 °C. If any of these conditions are unavoidable, it is necessary to determine the cable size which will prevent damage to the cable caused by overheating.

4.

As a guide only, and in accordance with BS 7671 we recommend close circuit protection:

i.e. 9.5 kW = 40 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.

The switch can be a ceiling mounted pullcord type within the shower room, or a wall mounted switch in an adjacent room.

5.

DO NOT twist the individual cable cores of either the live or neutral conductors, as this will prevent them from entering the terminal block.

6.

DO NOT exert strain on the terminal block. Ensure that the electrical connections are tightly screwed down.

7.

DO NOT turn on the electrical supply until the plumbing has been completed.
