Installation Requirements
Plumbing
1. The plumbing installation must comply with all national or local water regulations and all relevant building regulations, or any particular regulation or practice specified by the local water supply company.
2. The shower is designed to operate with a gravity fed water supply providing a pressure from 0.8 kPa* (0.008 bar / 80 millimetres head) to 100 kPa (1 bar / 10 metres head, the vertical distance from the base of the cold water cistern to the top of the shower unit). The shower must have its own separate supply from the cistern. DO NOT FIT THE SHOWER TO A MAINS WATER SUPPLY OR WHERE THE MAXIMUM SPECIFIED PRESSURE MAY BE EXCEEDED! Failure to comply with these restrictions may result in product damage not covered by the guarantee. * Note: In practice the minimum head required will increase with pipe length. See "Pipework" for further guidance which includes a calculation table to make sure that adequate head is available for any given installation.

25 Gallon/113 Ltr Cistern

25 mm

Correct Cistern Take Off
Positioned away from the ball valve, with a 25 mm distance from the base of the cistern. This connection will prevent air and debris entering the shower supply.

Incorrect Cistern Take Off
Debris from the bottom of the cistern and air generated when the cistern refills will enter the shower supply.

To shower unit only.

1383572-W2-A

3. DO NOT install the product in a position or location that will limit access for servicing.
4.A suitable position for the shower will have a minimum clear distance of 200 mm above and below the shower unit to allow for cover removal and refitting.
5. The position of the shower and shower fittings must provide a minimum air gap of 25 mm between the showerhead and the spill over level of any bath, shower tray or basin. There must be a minimum distance of 30 mm between the showerhead and the spill over lever of any toilet, bidet or other appliance with a Fluid Category 5 backflow risk.

Hose retaining ring fitted and shower fittings fixed at a suitable height preventing dirty water backflow

Note: There will be occasions when the hose retaining ring will not provide a suitable solution for Fluid Category 3 installations, in these instances an outlet double check valve must be fitted, this will increase the required supply pressure typically by 10kPa (0.1 bar). Double check valves fitted in the inlet supply to the appliance cause a pressure build up, which affect the maximum static inlet pressure for the appliance and must not be fitted. For Fluid category 5 double check valves are not suitable.

11

1383572-W2-A

6. The shower is suitable for installation within the shower area. The shower is fitted with an internal pressure relief valve and must be installed over a water catchment area.
7.Position the shower where the controls are at a convenient height for the user. Position the showerhead so that the water sprays in line with the bath or across the opening of a shower cubicle. The showerhead must not spray directly onto the shower unit during normal use. The installation must not cause the shower hose to be kinked during normal use.
8 The shower must be fitted to a waterproof, flat and even wall surface. The 3 screws (No.8 x 1�") and wall plugs supplied are suitable for most solid wall installations. Alternative fixing screws for panel structures are not supplied. Use all 3fixing points to secure the shower unit, be sure to use fixings appropriate for the chosen wall structure and environment.
DO NOT fit the shower to the wall and tile up to the case or seal the gap between the shower and the wall surface with sealant.
9 The shower is intended to be permanently connected to a gravity fed water supply using the inlet connection supplied as part of the shower unit.
DO NOT use any other type of fitting. 10.U se a minimum of 15 mm diameter supply pipework. For long pipe runs, this
should be increased to 22 mm (see "Pipework" for guidance and calculation table). When using flexible plastic pipe it is essential that the pipe is kept flat to minimise air build up in the system.
11. A full bore/non restrictive servicing valve must be fitted in a readily accessible position adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a build up of static pressure.
12.The shower is not designed to be plumbed directly from the rear. For rear-entry supply, add an elbow to the supply pipe and connect as a rising or falling supply. We recommend a falling supply to prevent air lock in the pipework.
13.If pipework and/or electrical cables enter the shower from the rear through a hole in the wall, provision must be made to prevent water ingress back into the wall structure.
14. DO NOT apply excessive force to plumbing connections; always provide mechanical support when making plumbing connections. Any soldered joints should be made before connecting the shower.
15.A water treatment device should be installed where the water hardness may exceed 200ppm. Malfunctions caused by excessive limescale formation are not covered by the guarantee.
16.D O NOT perform the electrical installation until the plumbing has been completed and checked for leaks.
17. The water supplies to this product should be isolated if the product is not to be used for a long period of time. If the product or pipework is at risk of freezing during this period they should also be drained of water.

1383572-W2-A

Many household and commercial cleaners, including hand and surface cleaning wipes contain abrasives and chemical substances that can damage plastics, plating and printing and should not be used. These finishes should be cleaned with a mild washing up detergent or soap solution, and then wiped dry using a soft cloth.
Important! Keeping the showerhead clean and free from limescale will ensure that your shower and showerhead continue to perform to their maximum. A blocked showerhead can restrict the flow rate and may cause damage to your shower. Use your thumb or a soft cloth to wipe any limescale from the nozzles.

Inspecting the Hose
Important! The shower hose should be inspected periodically for damage or internal collapse, internal collapse can restrict the flow rate from the showerhead and may cause damage to the shower.
Unscrew the hose from the showerhead and the shower outlet.
Inspect the hose.
Replace if necessary.
Warning! If you have to replace the shower fittings only use Mira Showerheads and hoses. Non-Mira manufactured showerheads and hoses can be restrictive leading to scalding temperatures or other personal injury.
Servicing
Warning! There are no user serviceable parts inside the shower. Servicing of the shower must only be carried out by qualified, competent personnel following the instructions provided in this guide and those provided with any spare part.
Cleaning / Replacing the Filter The filter can be removed from the lower left of the shower unit. Isolate the electrical supply to the shower unit before removing the filter. The water supply will shut off automatically as the filter is removed, however we recommend isolating the water supply to the shower unit to aid with refitting the filter. Note: Removing and replacing the filter allows a small amount of air into the product. The time it takes to clear the air will vary depending of the effective head of the installation.
