17. A water treatment device should be installed where the water hardness may
exceed 200 ppm. Malfunctions caused by excessive limescale formation are
not covered by this shower’s guarantee (see back page for details).

use.

and checked for leaks.
20.
Wall fixings are not supplied
. For solid wall structures a red rawl plug and a
no. 8 x 1½” countersunk brass or stainless steel screw should be used. For other
wall structures such as panels alternative fixings may be required. A minimum
of 3 fixing screws should be used.
Hose retaining ring fitted and shower fittings fixed at a suitable height
preventing dirty water backflow
Note: There will be occasions when the hose retaining ring will not provide
a suitable solution for Fluid Category 3 installations, in these instances
an outlet double check valve must be fitted, this will increase the required
supply pressure typically by 10kPa (0.1 bar). Double check valves fitted in
the inlet supply to the appliance cause a pressure build up, which affect
the maximum static inlet pressure for the appliance and must not be fitted.
For Fluid category 5 double check valves are not suitable.
