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.
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.
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.
