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 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.
5. The shower must be tted to a waterproof at and even wall
surface.
6. DO NOT t the shower to the wall and tile up to the case.
7. DO NOT seal the gap between the shower and the wall surface.
8. The showerhead should be positioned so that it discharges down the centre line of the bath or across the opening of a shower cubicle.
9. The showerhead must be directed away from the shower unit, during normal use the showerhead must not spray directly on to the shower unit.
10. 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.
11. 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.
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 tted, this will increase the required supply pressure typically by 10kPa (0.1 bar). Double checkvalves tted 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 tted. For Fluid category 5 double
checkvalves are not suitable.

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. This shower is intended to be permanently connected to the mains water supply, only use the inlet connection 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.
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
specied 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
xed 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 xed 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 tted in the applicable
zone area.
7. For new installations a 30mA Residual Current Device (RCD)
must be incorporated into the electrical supply to this shower in accordance with current wiring regulations. When replacing
an existing electric shower we recommend that a 30mA RCD
be incorporated in accordance with current wiring regulations if not already provided
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.
