1. Plumbing
Read the section "Important Safety Information" first.
1.1. Supply pipework MUST be flushed to clear debris before connecting the
appliance.
1.2. A hose retaining ring is supplied to prevent the handset from dropping below the
spill-over level of the bath or shower, which could lead to contamination from
back siphonage. The supplied hose retaining ring should meet the great majority
of user requirements for shower installations with flexible outlet fittings.
However, there will be occasions when the hose retaining ring will not provide
a suitable solution. In these instances an outlet double checkvalve may be
fitted.
1.3. Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
1.4. Do not fit any form of flow control in the outlet pipework if the shower fitting is
installed in conjunction with a product that requires the fitting to act as a vent
(e.g. an electric shower).
1.5. Do not use excessive force when making connections.
1.6. Do not install the product in a position where it could become frozen.
1.7. The layout and sizing of pipework should be such that when other services are
used, pressures do not fall below the recommended minimum for that fitting as
this will cause the spray pattern to collapse.
1.8. Perceived sound levels of the handset and spray impingement, will be affected
by the spray pattern selected and flow rates.
