1 GENERAL
1.1 Isolate the electrical and water supplies before
removing the cover.
1.2 Read all of these instructions and retain them
for later use.
1.3 DO NOT take risks with plumbing or electrical
equipment.
1.4 Isolate electrical and water supplies before
proceeding with the installation.
1.5 The unit must be mounted onto the nished
wall surface (on top of the tiles). DO NOT tile
up to or seal around ANY PART of the unit
using silicone sealer after xing to the wall.
Special care must be taken NOT TO BLOCK

should be in accordance with BS EN 806.
2.2 The supply pipe must be ushed to clear debris
before connecting to the shower unit.
2.3 DO NOT solder pipes or ttings within 300mm
of the shower unit, as heat can transfer along
the pipework and damage components.
2.4 DO NOT t any form of outlet ow control as
the outlet acts as a vent for the heater can.
2.5 DO NOT use excessive force when making
connections to the exible hose or
showerhead, nger tight is sufcient.
2.6 All plumbing connections must be completed
before making the electrical connections.
2.7 This appliance MUST NOT be connected to
the inlet supply by a hose-set.

‘Requirements for electrical installations’ (IEE
wiring regulations), building regulations or any
particular regulations as specied by the local
Electrical Supply Company.
3.2 This appliance MUST be earthed.
3.3 In accordance with ‘The Plugs and Sockets etc.
(Safety) Regulations 1994’, this appliance is
intended to be permanently connected to the
xed wiring of the electrical mains system.
3.4 Make sure all electrical connections are tight to
prevent overheating.
3.5 A 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.
3.6 Switch off immediately at isolating switch if
water ceases to ow during use.

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 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.
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.
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 nish and
invalidate your guarantee.
IMPORTANT ADVICE TO USERS
COMMISSIONING 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.
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.

CIRCUIT PROTECTION
Fig.4 Schematic of installation circuit
ELECTRICAL REQUIREMENTS
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufcient for the
amperage required.
The following notes are for guidance only:
1 The shower must only be connected to a
230-240V ac supply. If you are installing a
shower with a kilowatt rating above 9kW, it
is advisable to contact the local electricity
supply company.
1.1 The electrical rating of the shower is shown
on the rating label (Fig.3) within the unit.
2 Before 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.
3 The 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.
3.1 The electrical supply must be adequate for
the loading of the unit and existing circuits.
4 Check 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).
4.1 If 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.
4.2 You will need to contact the local electricity
company. They will check the supply and
carry out what is necessary.
5 For close circuit protection DO NOT use a
rewireable fuse. Instead use a suitably rated
Miniature Circuit Breaker (MCB) or cartridge
fuse (see Table A).
5.1 A 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.

*The method below may be used by
installers to determine the approximate
size of the incoming cable.
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 = 1.41mm
2
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.
6 A 45 amp double pole isolating switch with
a minimum contact gap of 3 mm in both
poles must be incorporated in the circuit.
6.1 It 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.
6.2 The 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.
7 Where shower cubicles are located in any
rooms other than bathrooms, all socket
outlets in those rooms must be protected by
a 30mA RCD.
8 The current carrying capacity of the cable
must be at least that of the shower circuit
protection (see Table B).
8.1 To obtain full advantage of the power
provided by the shower, use the shortest
cable route possible from the consumer unit
to the shower.
8.2 It 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.
9 The shower circuit should be separated from
other circuits by at least twice the diameter
of the cable or conduit.
9.1 The 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.
9.2 In 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.
9.3 In 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.
