ADVICE TO USERS
The following points will help you understand
how the shower operates:
IMPORTANT: 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.
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, so 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 while the shower is in use. If pressure
drops appreciably below the minimum, the
heating elements will automatically cut out.
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
and possibly damage the sealing rubber.

WARNING!
THIS APPLIANCE MUST BE EARTHED
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufficient 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.

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
identifiable, but out of reach of a person
using a fixed 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.

provided by the shower, use the shortest
cable route possible from the consumer unit
to the shower.
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, 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.

*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
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.

SITING OF THE SHOWER
IMPORTANT: If installing onto a tiled wall
always mount the unit on the surface of the
tiles. NEVER tile up to the unit.
Refer to (fig.6) 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. Leave
enough space between the right-hand side of the
unit and the wall to allow access to the pressure
relief device (PRD) in the future.
Note: Water regulations require 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’.
The use of the gel hanger/hose guide (if supplied)
will in most cases meet this requirement, but if the
showerhead can be placed within a bath, basin or
shower tray, then a double check valve, or similar,
MUST be fitted in the supply pipework to prevent
back-flow.
Pressure relief device - PRD
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
which can cause the PRD to operate.
When commissioning, the showerhead must
be removed from the flexible hose, while at the
same time the temperature control must be at
the minimum flow position. Failure to follow this
procedure may also cause the PRD to operate.
Make sure the shower is positioned over a bath
or shower tray because 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.
WARNING!
The shower must not be positioned
where it will be subjected to freezing
