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 handy
for future reference.
Mira Logic Power Shower Fittings
An adjustable spray handset with four different spray actions (start, champagne,
massage and eco*), supplied complete with flexible hose, clamp bracket assembly,
slide bar, supports, hose retaining ring/gel holder and wall mounted soap dish. Available
in white and white/chrome finish.
* The eco setting reduces the water flow on the start mode to give better economical
use of water, whilst still giving an adequate shower performance. This setting performs
best with pumped and mains pressure unvented systems. On some combination
boiler systems the economy setting will have no effect, and will give the same spray
action as the start setting.

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. Installations must comply with UK Water Regulations/ Bye-laws (Scotland), and
Building and Plumbing Regulations in force at the time of installation.
3. When installing the shower fittings in a cubicle, position with the spray pointing
across rather than toward the opening of the cubicle.
4. When installing the shower fittings over a bath, position with the spray pointing
down the centre line of the bath.
5. Avoid layouts where the shower hose will be sharply kinked. This may reduce the
life of the hose.
6 . Do not fit any form of flow control in the shower outlet.
7. Do not use excessive force when making connections.
8. Do not install the fittings in a position where it could become frozen.
9. The minimum pressure required for a satisfactory spray pattern to form, at the
handset or spray head, is 0.1 bar. For a gravity fed shower installation the minimum
head of water required, to accommodate the pressure loss in the pipes and shower
control of a typical installation, is 1.0 metre.
For a pump installation the minimum acceptable vertical distance between the
base of the cold water storage cistern and the shower head to operate the pump’s
flow switches, is typically 0.6 m (600 mm).
