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.

Mira Logic Power Shower Fittings

An adjustable spray handset with four different spray actions (start, champagne, massage and eco*), supplied complete with flexible hose, clamp bracket assembly, slide bar, supports, hose retaining ring/gel holder and wall mounted soap dish. Available in white and white/chrome finish.

* The eco setting reduces the water flow on the start mode to give better economical use of water, whilst still giving an adequate shower performance. This setting performs best with pumped and mains pressure unvented systems. On some combination boiler systems the economy setting will have no effect, and will give the same spray action as the start setting.

INSTALLATION REQUIREMENTS

Installation must be carried out in accordance with these instructions, and must be conducted by designated, qualified and competent personnel.

1. The hose retaining ring supplied must be used to stop the handset from dropping below the spill-over level of the bath or shower tray. This will prevent water supply contamination due to backsiphonage.

2. Installations must comply with UK Water Regulations/ Bye-laws (Scotland), and Building and Plumbing Regulations in force at the time of installation.

3. When installing the shower fittings in a cubicle, position with the spray pointing across rather than toward the opening of the cubicle.

4. When installing the shower fittings over a bath, position with the spray pointing down the centre line of the bath.

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

6 . Do not fit any form of flow control in the shower outlet.

7. Do not use excessive force when making connections.

8. Do not install the fittings in a position where it could become frozen.

9. The minimum pressure required for a satisfactory spray pattern to form, at the

handset or spray head, is 0.1 bar. For a gravity fed shower installation the minimum head of water required, to accommodate the pressure loss in the pipes and shower control of a typical installation, is 1.0 metre.

For a pump installation the minimum acceptable vertical distance between the base of the cold water storage cistern and the shower head to operate the pump’s flow switches, is typically 0.6 m (600 mm).

INSTALLATION

Note! For dry lined, stud partition, shower cubicle or laminated panel walls the installer

may wish to obtain alternative proprietary cavity fixings. Use of these alternative fixings is beyond the scope of this guide.

Important! If the Logic slide bar replaces an existing Mira slide bar make sure that the position of the shower control and the shower fittings provide a minimum of 25 mm between the handset and bath/tray spill-over level. This is necessary to prevent back-siphonage. If this is not possible then the new slide bar will have to be repositioned.

Slide Bar and Clamp Bracket

Read the section: Installation Requirements before proceeding with the installation. The slide bar should be positioned to one side of the shower control at a convenient

height for all the family. It should be positioned so that the handset discharges down the centre line of the bath, or across the opening of the shower cubicle. The handset should be directed away from the shower control.

1. Decide on a suitable position for the slide bar avoiding buried cables and pipes. Make sure that when the hose retaining ring is placed on the lowest position on the slide bar there is a minimum of 25 mm between the handset and bath/tray spill-over level. This is necessary to prevent back-siphonage.

2. Important! The slide bar has been supplied with an applicator fitted to one end (refer to illustration) to assist the assembly of the slide bar through the clamp bracket.

With the clamp bracket button FULLY depressed carefully ease the slide bar through the hole in the clamp bracket. Take care not to dislodge the constant friction mechanism or the friction pad.

3. Release the clamp bracket button. Remove the applicator from the slide bar and store in a safe place for future use.

4. Slide the hose retaining ring onto the slide bar below the clamp bracket.

5. Make sure that the slots in the slide

bar are aligned with the lugs in the support and fit the two slide bar supports to the ends of the slide bar. Make sure that each support is pushed firmly home.

Note! If replacing an existing Mira Slide Bar proceed to instruction 8.

6. Using the assembled slide bar and supports as a template, mark the position of the two fixing holes using the centre slot.

Warning! Make sure that there are no buried cables or pipes in the wall before drilling.

7. Drill the two 8 mm holes for the fixing screws and insert the wall plugs supplied. (Alternatively use proprietary cavity fixings for dry lined, stud partition, shower cubicle or laminated panel walls).

8. Fix the bottom slide bar support to the wall using the screw provided. Make sure that the screw is fully tightened.

9. Loosely screw the top slide bar support to the wall. Press firmly down on the top slide bar support and, while continuing to apply force, fully tighten the screw.

10. Fit the end caps to the slide bar supports.

11. Check the slide bar cannot be rotated or vertically moved. If there is movement remove the slide bar assembly from the wall. Check the slide bar support lugs are properly engaged with the slots in the slide bar and the supports are pushed fully onto the slide bar ends. Refit the slide bar assembly.

12. Refer to sections: Handset Installation and Soap Dish Installation to complete the fittings installation.

OPERATION

Changing Spray Settings

The handset has four different spray settings (start, champagne, massage and eco).

1. Eco Setting

Turn the spray plate fully clockwise. Water will flow from the outer set of holes and the flow rate will be reduced. This setting performs best with most gravity, pumped, and mains pressure unvented systems. On electric showers and some combination boiler systems the economy setting will have no effect, and will give the same spray action as the start setting.

2. Start

Turn the spray plate anticlockwise until it 'clicks' (one click from economy setting). Water will flow from the outer set of holes.

3. Champagne

Turn the spray plate anticlockwise until it 'clicks' (two clicks from economy setting). Water will flow from the large diameter holes.

4. Massage

Turn the spray plate anticlockwise until it 'clicks' (three clicks from economy setting). Water will flow from the inner set of holes.

Page 12

Clamp Bracket Adjustment

1. Depress the release button and slide

the clamp bracket assembly to the required position.

2. Move the handset to the required angle. A friction mechanism within the clamp bracket assembly will hold the handset at the desired angle.

FAULT DIAGNOSIS

The trouble shooting information tabled below gives details on what you can do as a user, should you encounter difficulties with the shower fittings whilst operating the shower. Before replacing any parts make sure that the underlying cause of the malfunction has been resolved.

Cause RemedyMalfunction

No flow or low flow rate from shower fittings.

Drip from spray plate assembly in handset.

Spray plate blocked.

Hose blocked or twisted.

Partially closed stop or servicing valve in supply pipe work to the shower control.

Head of water below minimum required.

Problem with shower control.

A small amount of water may be retained in the shower fitting after the shower control has been turned off. This may drain over a few minutes.

Problem with shower control.

Refer to section: Maintenance, Cleaning.

Clear blockage or release twist in hose or renew hose.

Open valve.

Raise cistern or fit Mira pump.

Refer to the shower control Installation and User Guide.

This is quite normal. Changing the angle of the shower fitting may vary the draining time.

Refer to the shower control Installation and User Guide.

Shower temperature changes when spray action is adjusted.

Adjusting the spray action changes the flow of water. This may affect some shower controls and plumbing installations.

To minimise the effect make sure that the spray plate is clean. Refer to section: Maintenance, Cleaning. If the malfunction persists refer to the shower control Installation and User Guide.
