Section 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 safe for future reference. 1. Description The Mira Enhance single impeller centrifugal pump is designed to receive a single gravity feed from a mixing valve and provide a pressurized supply to a fixed shower head or shower handset. - Page 6 To overcome an initial low flow rate in the outlet pipe it is possible to bypass the function of the flow switch by the addition of a momentary action switch connected in parallel with the flow switch (Refer to Figure 6).
