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 qualified 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 - 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 affect 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.

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-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.

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
flux to fall onto the casings.
Important: An additional independent stop valve complying with the
current water regulations must be fitted 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 flushed through to remove debris
and swarf that could otherwise damage the unit. Once the pipe
work has been flushed 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 first 25mm of plating is carefully removed to allow
push-fit fitting 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 11).
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 (7) securing the inlet connector elbow clamp
(8), remove the tab from the slot and keep until the inlet pipe is
repositioned. Lift the outlet connection (9) up out of the way from
its position at the bottom of the unit. Pull the inlet connector elbow

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, fit ‘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-fit 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-fit type fitting, 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 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 Customer Services.

Fixing Your Riser Rail to the Wall
Fitting the Riser Rail
Before proceeding with fitting the rail, identify each of the items
supplied using the illustration on the right.
The Slider should not be removed from the rail during fitting. The
underside of the slider has a button to release the slider and allows
the height to be adjusted.
Slide the soap dish 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 retaining hole
in the soap dish. Mark the wall to indicate the upper fixing 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 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.
Drill the wall at the marked fixing position to suit the wall fixings to
be used, loosely fix 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 fix 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 fixing
position and fix 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 fixing
screw. Insert end caps into the wall brackets at both ends of the rail.
When fitting the hose, it should pass through the larger hole of the
soap dish.
Note: The conical hose end and not the handset handle, fits into the
slider. Ensure the washer is fitted between the hose and the handset
handle. The slider moves more freely on the rail if gripped next to
the rail, rather than at the handset.

Commissioning - Testing the System
Warning: Before using the shower for the first time, it
should receive a final flush through and filter clean to remove
any remaining debris that may be in the pipe work or hose and
to ensure the heater unit contains water before the electrical
elements are switched on.
Remove the showerhead from the hose and if not already attached,
attach the hose to the outlet port and ensure that the outlet hose
mesh filter is fitted.
The temperature control knob (6) must be set fully clockwise to
minimum flow. (This is to prevent the PRD activating when water is
first 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 touch button (3).
Note: The unit has been factory set to first come on in the Cold ( )
Power position.
Only the Cold ( ) power touch button (4) should be illuminated
when first turned on. If not please press the cold ( ) power touch
button to obtain cold water only.
Wait approximately 30 seconds for the water to flow correctly.
Once the water has flowed for a further 10 seconds, rotate the
temperature control knob (6) from the fully clockwise position to the
fully anti-clockwise position. Repeat this procedure several times
until a continuous flow of water (with no air bubbles) is obtained
from the shower hose.
Once you are satisfied that the system has been flushed through
thoroughly, press the STOP/START touch button (3) to stop the flow.
Important: Isolate the electrical and water supply to the unit. Clean
the Inlet Filter and Outlet Hose Mesh Filter to remove any debris
from the flush - see Maintenance Section.
Note: If the words ‘LOW PRESSURE’
appear below the large numerical display
this indicates too low a water supply
pressure to the unit. Please switch off unit until water pressure
increases before continuing to use the shower.
Re-fit the showerhead to the hose, insert hose rubber washer to
seal the joint; please ensure that the hose passes through the
larger hole in the soap dish. The showerhead is attached to the riser
rail by inserting the conical hose end into the movable slider.
Your shower is ready for use.

If you did not fit this shower yourself and you are about to use it for
the first time, check with the installer to ensure he or she has run
the commissioning procedure as described on page 18.
To Start the Shower
Press the STOP/START touch button (3).
Note: The display will only light up once the STOP/START touch button
is pressed, then the temperature indicator display will start to count up.
During periods of high ambient temperatures (e.g. hot summer
days), it may be necessary to select a lower power setting in order to
achieve your ideal shower temperature.
When adjusting the temperature, including during first start up, do
not rapidly turn the dial to Max Temp to increase the temperature.
Instead, use small changes and wait for the new temperature to
settle before changing again.
To Stop the Shower
Press the STOP/START touch button (3).
Phased Shut Down: When the shower is turned off, water will
continue to flow for a short period of time while the heater cools
down. This ensures that the shower is ready for the next user. Do
not use the isolation switch (pull cord) to stop the shower, use the
STOP/START touch button (3).
It is always advisable to test the water temperature with your hand
before stepping under the shower. Please note that there is always a
delay of a few seconds between you selecting a temperature setting
and the selected water temperature starting to flow.

Adjusting the Showerhead
Your Bliss showerhead has 3 spray modes - spray, jet spray and
combination. Simply rotate the spray head one way or the other until
it ‘clicks’ into the desired spray pattern.
Note: The spray head mode may need to be altered during winter
conditions (low flow conditions) to achieve a satisfactory spray.

General Cleaning
Before attempting to clean your shower unit you must switch off
the power at the isolating switch. Do not remove the cover.
Do not use abrasive cleaners or solvents to clean this unit. The
shower unit and accessories should be cleaned with a soft, clean,
damp cloth.
Performance Maintenance Indication
Display shows “CL”. This is a performance Maintenance Indication
that routine service cleaning is advisable to maintain showering
performance. Follow the instructions to Clean the Showerhead,
Clean the Inlet Filter and Clean the Outlet Hose Mesh Filter.
Cleaning the Showerhead
Your Bristan showerhead has a rub-clean pad for easy cleaning.
Simply rub your fingers across the rubber spray jets regularly and
before you turn the shower on to remove any scale or debris.
The hardness of the water in your area will determine how often
you should clean your showerhead. Build up of scale in particularly
hard water areas combined with constant use means you may
need to clean your showerhead once a week. To ensure continued
performance of your electric shower the showerhead needs to be
regularly descaled.
