Temperature Control Device
The Temperature Control Device will activate when
the temperature is set too high and the water inside
the water heater gets too hot. The Temperature
Control Device will switch o the power to the
heating elements. Once the unit cools down to a
safe temperature the elements will come on again
and reheat the water within the water heater and the
whole cycle will repeat itself until the temperature is
manually reduced.
Warm-Up Mode
The light around the STOP/START Button will flash
as the water heats up. Once the light stops flashing
and stays on, the shower has reached your selected
temperature and is ready to use.
Phased Shut Down & Indication
When the shower is turned o, water will continue to
flow and the light around the STOP/START Button
will flash for a short period while the heater cools
down to approximately 30’C, before automatically
turning o. This helps reduce limescale build-up.
ThermoSafe™Technology

The Electrical Installation and Circuit Protection of this
shower must comply with current I.E.E Wiring Regulations
(BS 7671) and Building Regulations (Part P). We
recommend that this product is installed by a qualified
electrician prior to use. The following notes are for
guidance only.
Important: You must switch o the power at the consumer
unit, isolate the electrical circuit and verify the earth before
making any electrical connections.
The shower must only be connected to a 230-240V AC
supply. The electrical rating of your shower is on the pack or
on the rating plate label.
The shower must be connected to its own independent
electrical supply. It must not be connected to a ring main,
spur, power socket,
or lighting circuit.
If you don’t have a spare fuse way or the rating at the main
fuse box is below 80A, you should seek advice from an
electrician and may need a new consumer unit - specifically
for the shower.
A separate and permanently connected cable must be taken
from the consumer unit directly to the shower via a 45 Amp
double pole switch with a minimum contact separation gap
of 3mm in live (L) and neutral (N) poles.
The isolating switch can be a ceiling mounted pull cord
switch within the bathroom or wall mounted in an adjacent
room. The power switch must be easily accessible and
identifiable as the supply to the shower.
Note: Voltage drop in the supply to the premises, due to
heavy local demand, will aect the performance of your
shower. To gain the optimum power possible from this
shower unit try to find the shortest possible route from the
consumer unit to the shower to run your cable.

Electrical Requirements

It is a requirement that a residual current device
(RCD) formerly known as an earth leakage circuit
breaker (ELCB) with a tripping current of 30mA, is
incorporated in the circuit. This may be part of the
existing consumer unit or a separate unit.
For close circuit protection DO NOT use a rewireable
fuse. Instead use a suitably rated Miniature Circuit
Breaker (MCB) or Cartridge Fuse.
Please refer to the Circuit Protection Table.

Note: Cable selection is dependant on derating factors
On installation of the appliance the impedance
measurement of the Neutral and Earth back to the supply
source is to be less than 1.0 Ohms. This is in line with the
general installation requirements of the UK Network and
will generally present no problem within the UK Network.
In domestic installations you must ensure that the
electrical supply and existing fuse board are adequately
rated.
Do not turn on the electrical supply until the plumbing
has been completed and the shower cover re-fitted.

If the shower is to be installed in a hard water area, we
recommend that an in-line scale inhibitor is fitted which will
prolong the life of the shower. Please refer to your supplier
for advice.
Warning: The shower must not be installed in
an area subject to freezing conditions. Do not use
if you suspect the shower is frozen, this will
damage the shower unit.
The shower must be connected to a mains water supply
only with a minimum working inlet pressure of 0.07MPa
(0.7bar) at a minimum flow rate of 8 litres per minute. The
maximum static inlet pressure must not exceed 1.0MPa
(10bar).
If it is intended to operate the shower at pressures above the
maximum stated, a suitable pressure reducing valve (PRV)
should be used.
Water regulations stipulate that the showerhead be
‘constrained by a fixed or sliding attachment (hose retainer)
so that it can only discharge water at a point not less than
20mm above the spill over level of the bath or shower tray
or other fixed appliance’.
If a showerhead can sit within a bath, basin or shower tray,
you must fit a double check valve in the supply pipe work
to prevent back siphonage. If the showerhead can sit within
a WC then the air gap should be a type AUK3 not less than
20mm or twice the diameter of the inlet pipe to the fitting,
whichever is the greater.
This fitting needs to be installed in accordance with the
following Installation Requirements and Notes (IRN) to
ensure they meet the requirements of the Water Supply
(Water Fittings) Regulations 1999 and the Scottish Bylaws
2004.
The fitting shall be installed so that its outlet discharges
above the spill-over level of any fixed appliance as indicted
on the illustration below.
For backflow protection in premises or installations up to,
and including Fluid Category 3 and 5.
The vertical distance of the outlet above the spill-over level
shall be not less than 20mm or twice the diameter of the
inlet pipe to the fitting, which ever is the greater. If the fitting
cannot be installed as indicated it shall be installed with
a backflow prevention arrangement suitable for the Fluid
Category.

Warning: Please check for any hidden pipes and
cables before drilling holes in the wall.
Remove the 4 cover retaining screws and lift o the cover.
Do not try to remove the control knobs from the cover.
They are an integral part of the cover and must not be
removed.
If you are fitting the unit to a partition wall or a wall of
particularly friable (crumbly) substrate, you will need
appropriate fixings for the wall type.
Select the position for the shower unit over a bath or shower
tray using the installation template provided.
Important: The shower unit must be fitted to a flat,
waterproof surface. Under no circumstances should the
shower unit be attached to a wall and then tiled up to the
edges. The unit must be fixed on top of the wall surface.
Important: Use a spirit level to ensure the template is level.
Mark the 3 fixing points with a suitable pencil through the
paper. Remove the template from the wall and drill the wall
to suit the wall fixings to be used.
Tips:
A piece of insulation or masking tape positioned where
holes are to be drilled and before marking out the exact
position for the fixing holes will help stop the drill bit
from wandering, particularly on a tiled surface.
When working near a basin, bath or shower insert plug
or cover waste to prevent losing small parts.
Take care not to drop tools/equipment into basin, bath
or shower during shower installation.
Note: The unit can be hung temporarily on the top screws
to help with the positioning of the pipe work etc.
* The bottom screw should only be fitted during final
installation.
Important: Under no circumstances should this shower unit
be recessed (it must be fitted onto the finished wall surface)
or tiled up to or sealed around the unit as this may prevent
air circulating and any condensation escaping.
