Installation Requirements
Plumbing
1. The plumbing installation must comply with all national or local water regulations
and all relevant building regulations, or any particular regulation or practice
speciedbythelocalwatersupplycompany.
2. DO NOT install the product in a position in which service access is limited.
3. Decide on a suitable position for the shower (minimum distance of 200 mm from
theceilingtoallowforcovertandremoval).
4. Thepositionoftheshowerandshowerttingsmustprovideaminimumgapof
25 mm between the showerhead and the spill over level of any bath, shower
tray or basin and a minimum gap of 30 mm between the showerhead and the
spill over level of any toilet, bidet or other appliance with a Fluid Category 5
backowrisk(seediagramonpage10).
5. Theshowerissuitableforinstallationwithintheshowerareaandisttedwith
a pressure relief valve. It must be positioned over a water catchment area with
the controls at a convenient height for the user.
6. Theshowermustbettedtoawaterproofatandevenwallsurface.
7. DO NOTttheshowertothewallandtileuptothecase.
8. DO NOT seal the gap between the shower and the wall surface.
9. The showerhead should be positioned so that it discharges down the centre
line of the bath or across the opening of a shower cubicle.
10. The showerhead must be directed away from the shower unit, during normal
use the showerhead must not spray directly on to the shower unit.
11. DO NOT apply excessive force to plumbing connections; always provide
mechanical support when making plumbing connections. Any soldered joints
should be made before connecting the shower.
12. This shower is not designed to be plumbed directly from the rear. For rear-entry
supply, add an elbow to the supply pipe and connect as a rising or a falling
supply.
13. If pipework and/or electrical cables enter the shower from the rear through a
hole in the wall provision must be made to prevent water ingress back into the
wall structure.
14. Only use the inlet connector supplied with the shower. DO NOT use any other
typeoftting.
15.Afullbore/nonrestrictiveservicingvalvemustbettedinareadilyaccessible
position adjacent to the shower to facilitate maintenance of the shower.
DO NOT use a valve with a loose washer plate (jumper) as this can lead to a
build up of static pressure.

16. 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).
17. The installation must not cause the hose to be sharply kinked during normal
use.
18. DO NOT perform the electrical installation until the plumbing has been completed
and checked for leaks.
Hose retaining ring tted and shower ttings xed at a suitable height
preventing dirty water backow
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 tted, this will increase the required
supply pressure typically by 10kPa (0.1 bar). Double check valves tted in
the inlet supply to the appliance cause a pressure build up, which a󰀨ect
the maximum static inlet pressure for the appliance and must not be tted.
For Fluid category 5 double check valves are not suitable.

The shower's top priority is to keep the desired water temperature constant. Electric
showers with thermostatic control are able to keep a stable temperature across the
rangefromhottocold,whilstalsodealingwithuctuationsinelectricalandwater
