INSTALLATION REQUIREMENTS
Please read the Important Safety Information and specifications sections at
the front of this guide, and the requirements detailed in this section before
installing the shower.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY:
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
specified 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 fit and removal).
4. The position of the shower and shower fittings 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
backflow risk (see diagram on page 8).
5. The shower is suitable for installation within the shower area and is fitted 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 fitted to a waterproof flat and even wall surface.
7. DO NOT fit 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 fitting.
7
15. A full bore/non restrictive servicing valve must be fitted 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.

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
checkvalve must be fitted, this will increase the required supply pressure typically by
10kPa (0.1 bar). Double checkvalves 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 checkvalves are not suitable.

WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY:
Electrical
1. The electrical installation must comply with BS 7671 (commonly referred to as
the IEE Wiring Regulations) and all relevant building regulations, or any particular
regulation or practice specified by the local electricity supply company.
2. Ensure that all circuit protection devices, switches and cabling is adequate
for the rated current of the shower and that the rating of the electricity supply
company fuse and the consumer unit are adequate for the additional demand.
3. The shower must be earthed. Ensure any supplementary bonding complies
with the relevant regulations.
4. This shower is intended to be permanently connected to the fixed electrical wiring
of the mains system. A separate supply must be provided from the consumer
unit to the shower.
5. DO NOT supply any other electrical equipment including extractor fans or pumps
via this product.
6. This shower must be provided with means for local disconnection that is
incorporated into the fixed wiring in accordance with the relevant local wiring
regulations. This must be a double pole switch, which has at least 3 mm contact
separation in each pole. The switch can be a ceiling mounted pull-cord type within
the shower room or a wall mounted switch fitted in the applicable zone area.
7. A 30mA Residual Current Device (RCD) must be incorporated into the electrical
supply to this shower in accordance with wiring regulations.
8. DO NOT apply excessive force to the terminal block.
9. All electrical connections should be checked for tightness to prevent overheating
before switching on the electrical supply.
10. DO NOT switch on the electrical supply until the plumbing has been completed
and checked for leaks.
