Power showers combine the water from hot and cold supplies to reach the perfect temperature, while using a pump to offer incredible water pressure.
Here, we run through how to install a Mira Event XS thermostatic power shower. Remember that only a qualified professional should attempt power shower installation and you should always ensure that both the plumbing and electricity supplies are shut off before installing a power shower.
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.
- Decide on a suitable location for the Mira Event XS, avoiding buried cables and pipes. Leave a minimum distance of 200mm from the ceiling to allow for the fitting and removal of the cover. Ensure that when the hose retaining ring is placed on the lowest position on the slide bar, there is a minimum distance of 25mm between the handset and the bath or shower tray spillover when the handset is hanging down.
- Fit the three rubber feet into the recesses in the case. The feet will reduce the noise transmitted by the power shower through the wall.
- Remove the temperature knob concealing cap.
- Insert the end of the push-fit tool under the temperature control knob, in line with the temperature override button, and lever off the temperature knob.
- Unscrew the three retaining screws sufficiently to remove the shower cover. The cover retaining screws are captive and need not be removed.
- Using a spirit level, position the Mira Event XS on the wall and mark the three fixing points. Ensure the marked fixing points are not in line with buried cables and pipes before drilling.
- Drill 9.5mm holes and fit the rubber wall plugs supplied.
- Cut away and trim the thinned section in the top of the case to allow the electrical supply cable to run down the cable channel in the back of the case.
- Run the electrical supply cable into the surface-mounted miniature trunking (not supplied). Allow sufficient cable to connect to the Mira Event XS terminal block (approximately 275mm). Strip back approximately 30mm of outer cable insulation.
- Run the hot and cold water supply pipes at 28mm centres, ensuring that the pipe ends project into the Mira Event XS by 30mm to allow connection into the inlet manifold.
- Ensure that the end of the supply pipework is cut squarely and that it is free from burrs, which can damage the inlet manifold seals. Chamfer the end of the pipe to assist insertion into the fitting and to prevent the ‘O’ seal from tearing. Do not insert fingers into the push-fit connectors, as this can result in injury. Thoroughly flush the incoming hot and cold water supply pipes to remove debris before connecting the Mira Extreme shower.
- Push the supply pipework inside the inlet manifold until resistance is felt. Do not force it.
- The collet and ‘O’ seal will automatically make a hydraulic seal.
- 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.
- Screw the Mira Event XS T to the wall using either the supplied wall screws or alternative fixings, depending on the wall structure. Do not over-tighten. Ensure that the electrical supply cable is correctly seated in the channel in the back of the case.
- Connect the conductors of the electrical supply cable to the terminal block. The supply cable earth connector should be sleeved.
- Turn the flow spindle fully clockwise so that the flat is facing towards 11 o'clock.
- Turn the flow knob fully clockwise on the cover so that the indicator is pointing to the off position.
- Refit the cover and secure with the three cover retaining screws.
- Refit the temperature control knob and the concealing cap.
