Specifications 1. General 1.1. Ambient temperature – Maximum recommended ambient temperature for the appliance is 30°C. 1.2. Maximum recommended hot water temperature – 65°C. Warning! For safety reasons set the maximum stored hot water temperature to between 60 and 65°C. Such temperatures are considered sufficient to meet all normal requirements and will also minimise the deposition of scale in hard water areas. 1.3.
3. Electrical 3.1. Appliance power supply – 230–240 V, 50 Hz, fused at 3 Amps, via a double pole switched fused connection unit (not supplied) with a minimum 3 mm contact separation in each pole. 3.2. Power supply connection – The Mira Event XS is fitted with a terminal block which will accept cable up to 2.5 mm². Minimum cable size (cross-sectional area) required under normal installation conditions is 1 mm2. 3.3. Absorbed power - Approximately 150 W under normal working conditions. 4. Standards 4.1.
Installation Requirements 1. General 1.1. Do not take risks with plumbing or electrical equipment. 1.2. Do not install the Mira Event XS in a position where it could become frozen. 1.3. Isolate electrical and water supplies before proceeding with the installation of the Mira Event XS. 1.4. The shower control must be fed from a cold water storage cistern and hot water cylinder providing nominally equal pressures. 1.5. The installation must be carried out by a competent installer. 1.
2.6. A 30mA residual current device (RCD) must be fitted. This may be part of the consumer unit or a separate unit. 3. Plumbing 3.1. Do not use excessive force when making connections to the flexible hoses or handset, finger tightness is sufficient. 3.2. Do not solder supply pipework with the Mira Event XS connected. Heat transmitted through the pipework will melt the inlet manifold. 3.3. The storage cistern should have a minimum storage capacity of 230 litres to provide adequate showering time.
Use the table below to calculate the actual head of water (x) needed in your installation. A = Total length of 15 mm pipe in hot water supply pipe run* B = Total length of 22 mm pipe in hot water supply pipe run* C = Total length of 15 mm pipe in cold water supply pipe run* D = Total length of 22 mm pipe in cold water supply pipe run* *Measure from the base of the cold water cistern to the relevant inlet port on the Mira Event XS.
4. Installation Diagrams To prevent operational difficulties, the feed from the cylinder should be as illustrated below. Side entry cylinder bosses are not recommended because: • A drop in cylinder water level could expose a top entry immersion element if fitted. • Air-in-water solution gathers at the edge of the cylinder and in the centre, during the heating process before travelling up the vent. 25 mm minimum A A Warning pipe Cistern Minimum 1.
Installation 1. Before You Start Decide where to site the Mira Event XS power shower. It should be positioned at a height convenient for all the family. The fittings should be fitted so the handset sprays away from the Mira Event XS, either down the centre line of the bath or across the shower cubicle opening. The Mira Event XS can support top, bottom or wall entry configurations for both the water and power supplies.
2. Configuring Inlet Supplies The Mira Event XS is supplied with blanking plugs fitted to all four ports of the inlet manifold. The pipework configuration will determine which blanking plugs and case inserts supplied must be fitted to the case. Supply Pipework Inlet Manifold Ports Case Inserts Top Entry Inlet Fit blanking plugs to bottom ports of the inlet manifold. Fit half insert in the top inlet of the case. Fit full insert in the bottom inlet of the case.
This procedure removes the top two blanking plugs from the inlet manifold for top or wall entry pipe configurations. Using this procedure as a guide, adjust the steps for bottom entry configurations as appropriate. Cover Retaining Screws 2.1. Remove the temperature knob concealing cap. Push-fit Release Tool 2.2. Use the push-fit release tool to lever off the temperature knob.
3. Shower Installation The following installation procedure is based on a bottom entry pipework configuration (rising hot and cold water supplies) and a top entry electrical supply configuration (via miniature trunking from above). Using this procedure as a guide, adjust the steps for alternative water supply or electrical supply configurations as appropriate. 3.1. Decide on a suitable location for the Mira Event XS avoiding buried cables and pipes.
3.6. Using a spirit level position, the appliance on the wall, then mark through the three fixing points. Tip! Special consideration should be given to the strength of the fixing arrangements when installing on to a dry lined, stud partition or dry partition wall structure. Installers may wish to obtain alternative proprietary cavity fixings, or choose other options such as fabricating rear supports using wooden blocks, however, these methods of fixing are beyond the scope of this guide.
Run the hot and cold water supply pipes at 28 mm centres, ensuring that the pipe ends project into the Mira Event XS by 30 mm to allow connection into the inlet manifold. Caution! Do not use stainless steel piping for inlet pipework. Caution! If chrome plated copper pipework is used then all traces of chrome plate must be removed from the connecting surfaces.
Important! This Mira Event XS must be fixed to the wall at all three fixing positions. The fixing holes are elongated to assist in vertical and horizontal alignment. 3.14. Screw the Mira Event XS to the wall using either the supplied wall screws or alternative fixings depending on the wall structure. Flow Spindle Do not over-tighten! Ensure that the electrical supply cable is correctly seated in the channel in the back of the case. 3.15.
Commissioning 1. General Commissioning 1.1. Make sure the flow control knob is turned to the "stop" position and the electrical supply is isolated. If applicable remove the appropriate circuit fuse. Caution! Do not over-tighten the hose connector. 1.2. Connect the flexible hose from the shower fitting to the outlet of the appliance. Ensure the hose washer is fitted. 1.3. Turn the water supplies fully on at the isolating valves. Check that water is not leaking from the bottom of the case. 1.4.
Operation Warning! The shower is a manual mixing shower which can select water temperatures from FULL HOT to FULL COLD. If the temperature control knob is turned anticlockwise fully the shower will deliver water at the same temperature as the stored hot water temperature (this will be the same temperature as the hot tap water temperature). Note! The shower is a manual mixing shower. The showering temperature will change if the incoming water temperature changes.
Fault Diagnosis 1. User Maintenance The Mira Event XS is fully performance tested after assembly. Providing the Mira Event XS has been correctly installed and is operated as advised, difficulties should not arise. In the unlikely event that you experience problems with your appliance then the following procedure will enable you to undertake basic fault finding before contacting the person responsible for installing your shower. Malfunction Cause Remedy Shower temperature too cold.
2. Installer Maintenance The Mira Event XS is one part of an entire plumbing system. The fitting of a pump places additional requirements on the plumbing system. Some systems may require plumbing modifications to allow them to cope with higher flow rates. Providing the Mira Event XS has been correctly installed and is operated as advised, difficulties should not arise. Fault diagnosis and maintenance must be carried out by a competent person for whom the fault diagnosis table is provided.
