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 sufcient 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.

Installation - SITING OF THE SHOWER

SITING OF THE SHOWER

The installation must be in accordance with
Water Regulations/Bylaws - see page 10 for

water specifications

• If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service
for advice.

• If the stated flow rates are not available,
it may not be possible to achieve optimum
performance from the unit throughout
the year.

• During periods of high ambient temperatures
it may be necessary to select the economy
power setting to achieve your preferred
shower temperature.

NOTE: The T80 Pro Fit Eco flow rate is limited to
6 litres per minute, during the warmer months it
may be necessary to select the economy power
setting.

Fig.5 shows a typical system layout.

NOTE: The control knobs are an integral part of

the cover. Do not attempt to remove them.

• Lift the cover from the backplate and remove
the trimplate.

• Refer to (fig.7) for the correct siting of
the shower. Position the unit where it will
NOT be in direct contact with water from
the showerhead. Position the shower unit
vertically.

• Allow enough room between the ceiling and
the shower to access the cover top screws.

• Mark out entry points and routing of the
water and electric supplies into the shower.

WARNING

The shower MUST NOT be

positioned where it will be

subjected to freezing conditions.

IMPORTANT: Water regulations (fig.7)

• It is required that the showerhead be
‘constrained by a fixed or sliding attachment

so that it can only discharge water at a point
not less than 25mm above the spill-over level
of the relevant bath, shower tray or other
fixed appliance’.

• If the riser kit is supplied with a ‘soapdish
hose retainer’ or bespoke ‘hose retainer’, it
will in most cases meet this requirement. If
the showerhead can still be placed within a
bath, basin or shower tray within the 25mm
limit, then a double check valve, or similar,

MUST be fitted in the supply pipework
to prevent back-flow.

Pressure relief safety device

• A pressure relief device (PRD) is designed
into the shower unit which complies with
European standards. The PRD provides a level
of appliance protection should an excessive
build up of pressure occur within the shower.

DO NOT operate the shower with a damaged or
kinked shower hose, or a blocked showerhead.
This may cause the PRD to operate.

• When commissioning, the showerhead
must be removed from the flexible hose.
Failure to follow this procedure may cause
the PRD to operate.

• Make sure the shower is positioned over a
bath or shower tray. If the PRD operates,
then water will eject from the bottom of
the unit. Should this happen, turn off the
electricity and water supplies to the shower
at the isolating switch and stopvalve.
Contact Customer Service for advice on
replacing the PRD.

IMPORTANT: The unit must be mounted on
a flat surface which covers the full width and
length of the backplate. It is important that
the wall surface is flat otherwise difficulty
may be encountered when fitting the cover
and subsequent operation of the unit may
be impaired.

IMPORTANT: If installing onto a tiled wall,
ALWAYS mount the unit on the surface of
the tiles. NEVER tile up to the unit.
