2.6All plumbing connections must be completed before making the electrical connections.
2.7This appliance MUST not be connected to the inlet supply by a hose-set.
3ELECTRICAL
3.1The installation must comply with BS 7671 ‘Requirements for electrical installations’ (IEE wiring regulations), building regulations or any particular regulations as specified by the local Electrical Supply Company.
3.2This appliance MUST be earthed.
3.3In accordance with ‘The Plugs and Sockets etc. (Safety) Regulations 1994’, this appliance is intended to be permanently connected to the fixed wiring of the electrical mains system.
3.4Make sure all electrical connections are tight to prevent overheating.
3.5A 30mA residual current device (RCD) MUST be installed in all UK electric and pumped shower circuits. This may be part of the consumer unit or a separate unit.
3.6Switch off immediately at isolating switch if water ceases to flow during use.

in a safe way and understand the hazards involved. Children may not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.
GENERAL ADVICE TO USERS
The following points will help you understand how the shower operates:
a.The electric heating elements operate at a constant rate at your chosen power setting. It is the rate of the water passing through the heater can which determines the water temperature. (The slower the flow, the hotter the water becomes; the faster the flow, the cooler the water).
b.During winter, the mains water supply will be cooler than in the summer. The flow rate will vary between seasons at any one temperature setting. At different times of the year you may have to adjust the position of the temperature control to maintain your desired temperature setting.
c.The stabiliser valve minimises variations in shower temperature during mains water pressure changes. If changes in shower temperature are experienced during normal use, it will most likely be caused by the water pressure falling near to or below the minimum level. The drop in pressure may be due to water being drawn off at other points in the house whilst the shower is in use. If pressure drops appreciably below the minimum, the heating elements will automatically cut out.
NOTE: If ever the water becomes too hot and you cannot obtain cooler water, first check that the sprayplate in the showerhead has not become blocked.
DO NOT place items such as soap or shampoo bottles on top of the unit. Liquid could seep through the joint between the cover and backplate.
IMPORTANT ADVICE TO USERS
COMISSIONING ADVICE
When first installed the unit will be empty. It is essential the unit should contain water before the elements are switched on. It is vital that the commissioning procedure is followed. Failure to carry out this operation will result in damage to the unit and will invalidate the guarantee.
ADVISORY - CLEANING
It is recommended that all products are cleaned using warm, soapy water.
DO NOT use abrasive or aggressive chemical cleaning products as this may affect the product surface finish and invalidate your guarantee.
Please read this book thoroughly and familiarise yourself with all instructions before commencing installation and keep it for future reference.
The shower installation MUST be carried out by a suitably qualified person, in the sequence of this instruction book.

THIS APPLIANCE MUST BE EARTHED |
||
The installation, supply cable and circuit protection must conform with BS 7671 (IEE wiring regulations) and be suf cient for the amperage required.
The following notes are for guidance only: 1
1.1The electrical rating of the shower is shown on the rating label (Fig.3) within the unit.
2Before making any sort of electrical connection within the installation make sure that no terminal is live. If in any doubt, switch off the whole installation at the mains supply and remove the correct fuse.
3The shower must be connected to its own independent electrical circuit. IT MUST NOT be connected to a ring main, spur, socket outlet, lighting circuit or cooker circuit.
3.1The electrical supply must be adequate for the loading of the unit and existing circuits.
4Check your consumer unit (main fuse box) has a main switch rating of 80A or above and that it has a spare fuse way which will take the fuse or Miniature Circuit Breaker (MCB) necessary for the shower (Fig.4).
4.1If your consumer unit has a rating below 80A or if there is no spare fuse way, then the installation will not be straightforward and may require a new consumer unit serving the house or just the shower.
4.2You will need to contact the local electricity company. They will check the supply and carry out what is necessary.
5For close circuit protection DO NOT use a rewireable fuse. Instead use a suitably rated Miniature Circuit Breaker (MCB) or cartridge fuse (see Table A).
5.1A 30mA residual current device (RCD) MUST be installed in all UK electric and pumped shower circuits. This may be part of the consumer unit or a separate unit.

6A 45 amp double pole isolating switch with a minimum contact gap of 3 mm in both poles must be incorporated in the circuit.
6.1It must have a mechanical indicator showing when the switch is in the OFF position, and the wiring must be connected to the switch without the use of a plug or socket outlet.
6.2The switch must be accessible and clearly
able, but out of reach of a person
u xed bath or shower, except for the cord of a cord operated switch, and should be placed so that it is not possible to touch the switch body while standing in a bath or shower cubicle. It should be readily accessible to switch off after using the shower.
7Where shower cubicles are located in any rooms other than bathrooms, all socket outlets in those rooms must be protected by a 30mA RCD.
8The current carrying capacity of the cable must be at least that of the shower circuit protection (see Table B).
8.1To obtain full advantage of the power provided by the shower, use the shortest cable route possible from the consumer unit to the shower.
8.2It is also necessary to satisfy the disconnection time and thermal constraints which means that for any given combination of current demand, voltage drop and cable size, there is a maximum permissible circuit length.
9The shower circuit should be separated from other circuits by at least twice the diameter of the cable or conduit.
9.1The current rating will be reduced if the cabling is bunched with others, surrounded by thermal loft or wall insulation or placed in areas where the ambient temperature
is above 30°C. Under these conditions, derating factors apply and it is necessary to select a larger cable size.
9.2In the majority of installations (see Table B), the cable will unavoidably be placed in one or more of the above conditions. This being so, it is strongly
recommended to use a minimum of 10mm cabling throughout the shower installation.

9.3In any event, it is essential that individual site conditions are assessed by a competent electrician in order to determine the correct cable size and permissible circuit length.

1.Measure the width of an individual strand, and half that measurment to find (r),
e.g: 1.34mm ÷ 2 = (r) 0.67mm
2.Multiply (r) x (r) x 3.14,
e.g: (r) 0.67 x (r) 0.67 x 3.14 = 1.41mm2
3.Multiply this by the number of wire strands (usually 7), e.g: 1.41mm2 x 7 = 9.87mm2.
4.The number obtained would suggest 10mm2 wiring.
*PLEASE NOTE: If unsure, consult a qualified Electrician.
