Electrical Requirements
Warning: This appliance MUST
be earthed!
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 qualied
electrician prior to use. The following notes are for
guidance only.
Important: You must switch off 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 - specically
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
identiable as the supply to the shower.
Note: Voltage drop in the supply to the premises, due to
heavy local demand, will affect the performance of your
shower. To gain the optimum power possible from this
shower unit try to nd the shortest possible route from the
consumer unit to the shower to run your cable.

Electrical Requirements cont.
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.
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-tted.

If the shower is to be installed in a hard water area, we
recommend that an in-line scale inhibitor is tted 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 ow 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 xed 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 xed appliance’.
If a showerhead can sit within a bath, basin or shower tray
(Fluid Category 3), you must t a veriable double check
valve in the supply pipe to prevent back siphonage.
If the showerhead can sit within a WC (Fluid Category 5)
then the air gap (Type AUK 3) shall be not less than 20mm or
twice the diameter of the inlet pipe to the tting, whichever
is the greater.

This tting 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
Byelaws 2004.
All water ttings connected to the plumbing system require
an assessment of the risk of contamination by backow.
The regulations dene the levels of contamination risk, called
Fluid Categories, based upon the nature of contaminants.
Fluid Category 3 are uids which represent a slight health
hazard such as common household disinfectants and Fluid
Category 5 are uids which represent a serious health
hazard such as human waste.
The tting shall be installed so that its outlet discharges
above the spill-over level of any xed appliance such as a
bath or shower tray as indicated on the illustration below.
For backow protection in premises or installations where
a Fluid Category 5 is present;-
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 tting, which ever is the greater. If the tting
cannot be installed as indicated it shall be installed with
a backow prevention arrangement suitable for the Fluid
Category.

Warning: The outlet of the shower acts as a vent and
must not be blocked, restricted or connected to any tap/
closure device other than the handset supplied.
Do not solder within 300mm of the shower unit or allow
solder or ux to fall onto the casings.
Important: An additional independent stop valve complying
with the current water regulations must be tted in the
mains water supply as a means of isolating the supply to the
unit for servicing and/or maintenance work.
It is essential that all pipe work is ushed through to remove
debris and swarf that could otherwise damage the unit.
Once the pipe work has been ushed through, turn off the
water supply at the stop valve.
Connect the mains water supply to the inlet port of the
shower using 15mm copper pipe (BS EN1057) or 15mm
plastic pipe (with insert).
Do not use stainless steel pipe work. If using chrome plated
pipe ensure that the rst 25mm of plating is carefully
removed to allow push-t tting to grip the inlet pipe.
Inlet Entry Options
The pipe work can enter the shower unit from 6 different
positions. Bottom left, Bottom right, Top left, Rear left, Rear
right or Rear left - using an elbow (as shown on page 9).
To top or bottom left positions
The shower unit should come supplied with the inlet
connection set for a bottom left position. To change it to
a top left position: swivel the inlet connector elbow from
facing downward to facing upward.
To bottom right position
Unfasten the screw (4) securing the inlet connector elbow
clamp (5), remove the tab from the slot and keep until the
inlet pipe is repositioned. Lift the outlet connection (6) up
out of the way from its position at the bottom of the unit.

Hole Cover Fitting
Top left entry: Depending on your choice of cold-water
entry direction, you may need to remove thin areas of plastic
cover to facilitate pipe work entry down through the top left
of the unit.
Bottom entry: Depending on your choice of cold-water
entry direction, t ‘hole covers’ to the pipe work slots at the
bottom of the unit.
Note: The grey areas shown are tabs that can be removed to
allow 6mm cable entry only.
Water Connection
The inlet pipe connection into the elbow is a self-seal push-
t type. All burrs and rough edges must be removed from
the end of the pipe before connecting.
To release the pipe work from the push-t type tting, press
and hold the collet against the elbow and pull the pipe out
of the elbow.
Turn on the water supply and inspect for water leaks at the
shower inlet. Once inspected-turn off the water supply.
Pressure Relief Device (PRD)
A pressure relief device is designed into this shower.
The pressure relief device provides protection should an
excessive build up of pressure occur within the shower unit.
It is advisable to position the shower unit over a bath or
shower tray to contain water released in the unlikely event
the device should discharge.
Do not use the shower with a damaged or kinked shower
hose or blocked handset. This may trigger the PRD which
will discharge through the vent in the bottom right hand
corner (shown).
In the event of the PRD activating, water will be discharged
from the vent. If this happens, switch off the electricity and
water supplies to the shower and contact your point of
purchase.

Need help? For further technical help or advice please contact your point of purchase.
Fitting the Riser Rail
Before proceeding with tting the rail, identify each of the
items supplied using the illustration on the right.
The Slider should not be removed from the rail during tting.
The underside of the slider has a button to release the slider
and allows the height to be adjusted.
Slide the soap dish and hose retainer onto the bottom end
of the rail. Position a wall bracket onto each end of the rail,
ensuring the hole through the top of the rail lines up with the
hole in a wall bracket.
Position the rail on the wall, bearing in mind the different
heights of people likely to use the shower and the length of
the hose when connected to the shower and passed through
the hose retainer. Mark the wall to indicate the upper xing
screw position.
Warning: Please check for any hidden pipes and cables
before drilling holes in the wall.
Tips:
A piece of insulation or masking tape positioned where
holes are to be drilled and before marking out the exact
position for the xing 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.
Drill the wall at the marked xing position to suit the wall
xings to be used, loosely x the rail (with the large hole
on the side shown) and wall bracket. Check that the rail is
hanging vertically using a spirit level.
Slide the lower wall bracket onto the rail and mark its required
position onto the wall.
Note: The lower wall bracket does not x to the riser tube and
can be positioned along the riser tube so as to cover either an
existing riser hole in the wall or over a tile joint.
Remove the lower bracket from the rail and unscrew the
upper bracket from the wall. Mark and drill the lower wall
bracket xing position and x the bracket to the wall. Slide
the rail down through the lower wall bracket and reattach the
upper bracket.
Check that the rail is perfectly vertical and tighten the upper
xing screw. Insert end caps into the wall brackets at both
ends of the rail.
When tting the hose, it should pass through the hose retainer.
Note: The conical hose end and not the handset handle, ts

activating when water is rst turned on).
Turn on the water supply and inspect for water tightness.
Turn on the mains electrical supply to the shower.
Press the STOP/START button (1). Wait approximately 30
seconds for the water to ow correctly. Once the water
has owed for a further 10 seconds, rotate the temperature
control knob (3) from the fully clockwise position to the fully
anti-clockwise position. Repeat this procedure several times
until a continuous ow of water (with no air bubbles) is
obtained from the shower hose.
Once you are satised that the system has been ushed
through thoroughly, press the STOP/START button (1) to
stop the ow.
Re-t the showerhead to the hose, insert hose rubber
washer to seal the joint; please ensure that the hose passes
through the hose retainer. The showerhead is attached
to the riser rail by inserting the conical hose end into the
movable slider.
Your shower is now ready for rst use.
