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. The shower is designed to operate with a gravity fed water supply providing
apressurefrom0.8kPa*(0.008bar/80millimetreshead)to100kPa(1bar
/ 10 metres head, the vertical distance from the base of the cold water cistern
to the top of the shower unit). The shower must have its own separate supply
from the cistern.
DO NOT FIT THE SHOWER TO A MAINS WATER SUPPLY OR WHERE THE
MAXIMUM SPECIFIED PRESSURE MAY BE EXCEEDED!
Failure to comply with these restrictions may result in product damage not
covered by the guarantee.
 *Note: In practice the minimum head required will increase with pipe length.
See “Pipework” for further guidance which includes a calculation table to make
sure that adequate head is available for any given installation.

3. DO NOT install the product in a position or location
that will limit access for servicing.
4. A suitable position for the shower will have a minimum
clear distance of 200 mm above and below the
showerunittoallowforcoverremovalandretting.
5. Thepositionoftheshowerandshowerttingsmust
provide a minimum air gap of 25 mm between the
showerhead and the spill over level of any bath,
shower tray or basin. There must be a minimum

spill over lever 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 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.

6. The shower is suitable for installation within the shower area. The shower is
ttedwithaninternalpressurereliefvalveandmustbeinstalledoverawater
catchment area.
7. Position the shower where the controls are at a convenient height for the user.
Position the showerhead so that the water sprays in line with the bath or across
the opening of a shower cubicle. The showerhead must not spray directly onto
the shower unit during normal use. The installation must not cause the shower
hose to be kinked during normal use.
8 The shower must be tted to a waterproof, at and even wall surface. The
3 screws (No. 8 x 1¼”) and wall plugs supplied are suitable for most solid wall
installations.Alternativexingscrewsforpanelstructuresarenotsupplied.Useall
3xingpointstosecuretheshowerunit,besuretousexingsappropriatefor

DO NOTttheshowertothewallandtileuptothecaseorsealthegapbetween
the shower and the wall surface with sealant.
9 The shower is intended to be permanently connected to a gravity fed water
supply using the inlet connection supplied as part of the shower unit.
DO NOTuseanyothertypeoftting.
10. Use a minimum of 15 mm diameter supply pipework. For long pipe runs, this
should be increased to 22 mm (see “Pipework” for guidance and calculation
table).Whenusingexibleplasticpipeitisessentialthatthepipeiskeptatto
minimise air build up in the system.
11. 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.
12. The 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 falling supply.
We recommend a falling supply to prevent air lock in the pipework.
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. 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.
15. 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 the guarantee.
16. DO NOT perform the electrical installation until the plumbing has been completed
and checked for leaks.
17. The water supplies to this product should be isolated if the product is not to be
used for a long period of time. If the product or pipework is at risk of freezing
during this period they should also be drained of water.

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 pull-cord type mounted to the
ceiling within the shower room or a rocker type switch mounted to the wall in
the applicable zone area.
6. For new installations a 30 mA Residual Current Device (RCD) must be
incorporated into the electrical supply to the shower in accordance with the
current wiring regulations. When replacing an existing electric shower we
recommendthata30mARCDisincorporatedinaccordancewithcurrentwiring
regulations if not already provided.
7. Check all electrical connections are tight, to prevent overheating, before
switching on the electrical supply.
DO NOT apply excessive force to the terminal block.
