Important information
THIS INSTALLATION AND USER GUIDE IS DESIGNED TO ENSURE THE SAFETY OF THE INSTALLER AND USER AND THE
OPERATION/RELIABILITY OF THE PRODUCT. FAILURE TO OBSERVE THESE MAY CAUSE A HAZARD, DAMAGE THE PRODUCT AND
INVALIDATE YOUR GUARANTEE.
Safety information
This product must be installed by a competent person in accordance with all relevant current water supply regulations.
The electrical installation should be carried out by a qualified person in accordance with IEE (Institute of Electrical Engineers) wiring
regulations (BS 7671) and certified to current building regulations. With reference to building regulation Part P, any new installation or
replacement product installation which is not identical to the product being replaced, the cable sizes, circuit protection devices, earth
bonding and all other requirements of the building regulation must be assessed by a (registered) qualified electrician and installed to
the site conditions (see table in electrical rating).
THIS APPLIANCE IS NOT INTENDED FOR USE BY PERSONS (INCLUDING CHILDREN) WITH REDUCED PHYSICAL, SENSORY OR
MENTAL CAPABILITIES OR LACK OF EXPERIENCE AND KNOWLEDGE UNLESS THEY HAVE BEEN GIVEN INITIAL SUPERVISION OR
INSTRUCTION CONCERNING THE USE OF THE APPLIANCE BY A PERSON RESPONSIBLE FOR THEIR SAFETY. CHILDREN SHOULD BE
SUPERVISED TO ENSURE THAT THEY DO NOT PLAY WITH THE APPLIANCE.
THIS PRODUCT IS SUITABLE FOR DOMESTIC USE ONLY
Pipework connections
This shower unit is designed for use with 15mm British Standard pipe and must be fitted with a copper olive. This product is suitable
for top, bottom or rear entry pipe work and cable connections. Supply lines should be flushed clear of any debris prior to installation of
the unit.
Plastic pipe may be used (with appropriate inserts) if certified by the plastic pipe manufacturer for use with compression fittings.
The copper olive provided must be used.
WARNING: PLASTIC PIPE INSERTS CAN BE VERY RESTRICTIVE. WHERE USED THE PRESSURE / FLOW REQUIREMENTS DETAILED IN
THE PRESSURES SECTION OVERLEAF MUST BE MET.
Pipe runs in the loft or behind radiators should be avoided.
Isolating valves
A suitable full bore isolation valve must be fitted to the incoming supply in accordance with the current water supply regulations and
our terms of warranty. The isolation valve must be sited in an accessible location for service and maintenance purposes.
Siting
The unit must be mounted on a flat, vertical finished wall with the hose pointing downwards. Any distortion of the back plate may
result in the unit not working.
DO NOT tile up to or use sealants around the unit. The shower is spaced off the wall by integral pillars to allow air circulation around
the unit.
The casing must not be sited where it is subject to continuous spray from the shower head.
The Vitalise SLX variant unit should be sited in a position where the LCD display is easily visible by the users.
The unit must not be sited where it is likely to freeze.
The rail system must be sited in a position where the hose when connected to the shower unit is not stretched or kinked.
WARNING: DO NOT SWITCH THE SHOWER ON IF THERE IS A POSSIBILITY THAT THE SHOWER COULD BE FROZEN. IF YOU HAVE
SWITCHED THE SHOWER ON, SWITCH OFF IMMEDIATELY (Please refer to the troubleshooting guide page 17).

Pressures
Check that the supplied dynamic (running) water pressure to the electric shower is adequate.
The required supplied dynamic (running) pressure is:Maximum 1.0MPa (10 Bar)
Minimum 0.07MPa (0.7 Bar) at a flow rate of 8 litres per minute.
Where pressures are likely to exceed 1.0MPa (10 bar), a pressure reducing valve must be fitted to the incoming mains supply. A setting
of 0.3MPa (3 bar) is recommended. It should be noted that daytime pressures approaching 8 bar can rise above the stated maximum.
The use of other services connected to the same water supply as the shower unit may cause the water pressure to drop below the
minimum required. This should therefore be taken into consideration.The minimum pressure/flow rate provided by your water supplier
may be below the requirements of this product. Contact your water provider for more details. Note: The running pressure at your
shower can be lower than this due to pressure losses in the internal pipe work in your home.
Note: Models of electric showers can differ in performance; if your previous electric shower had a lower output flow rate, then
this may have produced a higher dynamic pressure at the shower head.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will attack the working parts of this unit. All soldering must be
completed and the pipe work thoroughly flushed out in accordance with current Water Supply Regulations prior to connection of the
product.
Pressure relief device (PRD)
To meet European standards, the shower unit features an integral pressure relief device (PRD). The PRD provides a degree of shower
unit protection should an excessive build up of pressure occur within the shower.
DO NOT operate the shower with a damaged or kinked hose or blocked shower head, as this can cause excessive water temperature
and/or the PRD to operate. Failure to follow this instruction will invalidate the product guarantee.
The outlet must not be connected to any tap or fitting, including water saving handsets and flow restrictors, other than those
specified as the shower will only function correctly with the hose and handset provided (see showerhead installation instructions
from page 12). The use of alternative shower heads and/or hoses can cause excessive, potentially scalding, water temperature and/or
the PRD to operate and will invalidate the product guarantee.
Please fully commission the shower prior to use following the instructions on page 14. Failure to do this could cause the PRD to
operate and will invalidate the guarantee.
The shower must be sited over a bath or shower tray as in the event of the PRD operating water will drain from the bottom of the
shower unit.

Electrical installation
!
BEFORE ANY ELECTRICAL CONNECTION IS ATTEMPTED, THE ELECTRICITY SUPPLY MUST BE TURNED OFF AT THE MAINS
SWITCH. FAILURE TO DO SO COULD RESULT IN ELECTROCUTION.
The electrical installation should be carried out by a qualified person in accordance with IEE (Institute of Electrical
Engineers) wiring regulations (BS7671).
THIS APPLIANCE MUST BE EARTHED.
IN THE INTERESTS OF ELECTRICAL SAFETY, A 30mA RESIDUAL CURRENT DEVICE (RCD) MUST BE INSTALLED IN ALL UK
230-240V ELECTRIC SHOWERS. THIS MAY BE PART OF A CONSUMER UNIT OR A SEPARATE UNIT.
A suitable double-pole isolating switch for supply disconnections must be incorporated in the fixed wiring circuit in
accordance with current wiring rules. This must have a mechanical indicator showing when the switch is in the OFF position.
A neon lamp alone is not sufficient. (see the typical sysytem diagram in the MAINS VOLTAGE CONNECTION section
overleaf). If it is fitted in the bathroom it must be a cord operated type. The switch must be readily accessible and clearly
identifiable in zone 3 i.e. at 0.6m horizontally from the shower cubicle or edge of bath, or located above zone 2 (i.e. adjacent
to the shower cubicle or edge of bath, but at least 2.25m from the floor) as detailed below. This requirement does not apply
to the pull cord from the switch. See illustration overleaf.
Where shower cubicles are located in rooms other than bathrooms, any socket outlet in the room must be situated at least
3m from the shower cubicle and protected by a 30mA RCD.

BEFORE ANY ELECTRICAL CONNECTION IS ATTEMPTED, THE ELECTRICITY SUPPLY MUST BE TURNED OFF AT THE
MAINS SWITCH. FAILURE TO DO SO COULD RESULT IN ELECTROCUTION.
1
The shower unit must only be fitted to a 230-240V ac supply.
2
The shower unit must be connected to its own independent electrical circuit. It MUST NOT be connected to a ring main,
spur, socket outlet or lighting circuit, otherwise the circuit will overheat.
3
Check that the consumer unit (main fuse box):
a) Has a main switch rating of 80A or above and
b) Has a spare fuse way which will take the fuse/mcb (miniature circuit breaker) that you need to fit.
If so you can wire the shower direct to the consumer unit (please refer to the typical system diagram overleaf).
(Not all consumer units accept a 35/40/45A sized fuse).
!
If the consumer unit has a rating below 80A or if there is no spare fuse way, then the installation will not be straightforward.
It may be necessary to install a new consumer unit to service the whole house or just the shower. A qualified person should
install this. It may be necessary to contact the electricity supplier to upgrade the incoming supply.
Electrical rating
!
Refer to the electrical rating diagram (shown below) to determine the nominal current of the shower. The current rating of
the supply cable must be at least that of the shower itself. Use the chart to choose a fuse or mcb with a rating of less than
that of your chosen cable.

If upgrading to a higher kW shower it is essential to ensure that the electrical circuit, including the wiring and isolating switches
are adequate for the increased load.
Notes:1. Cable selection is dependant on de-rating factors detailed in the notes below.
2. In certain installations the combination of low voltage and extended cable lengths may result in loss of power and a
consequential reduction in flow rates.
3. Above cable sizes are the minimum acceptable sizes. Sizes greater than these shown above may be used and should be used if
cable runs are greater than indicated (above cable runs are based on a maximum 9.6v drop).
4. Rewirable fuses are not recommended and are not covered by this table.
5. Installation should be carried out by a qualified person. Please refer to BS7671 (Wiring regulations) if in doubt.
6. A 16mm² cable may be required for long cable runs.
Cables which are chased into the wall must be protected by the use of a conduit or sheathing. Surface mounted cables must also
be protected by a suitable approved conduit.
The current rating will be reduced if the cable is:
a. Bunched with others.
b. In an ambient temperature above 40oC.
c. In an insulated wall or within thermal insulation, e.g. loft insulation.
d. In any other unusual position.
If in doubt about any aspect of electrical insulation, consult a qualified electrical engineer or the electricity supplier.
!
WE STRONGLY RECOMMEND NOT USING REWIRABLE FUSES.
Wiring installation
1
Loosen the terminal screws and insert the wires as indicated on the back plate moulding.
2
Resecure the terminal block screws. Ensure connections are tight and secure to prevent
overheating.
!
Any cable MUST NOT have the outer insulation stripped back beyond the bottom of the backplate
and must be protected from water as shown.
16mm cable can only be used for bottom entry due to the ability to bend the cable.
11
3
If fitting the shower unit with bottom entry connections remove the blanking cap from the service
tunnel.
4
Place the service tunnel onto the shower unit ensuring it fits flush with the shower unit back plate.
Earth bonding
!
The installation must be earth bonded in accordance with current regulations.
Where earth bonding of the premises is not evident, it may be necessary to run a bonding cable back to the earth
terminal at the consumer unit.
Shower head installation
The shower head should be sited close to the shower unit, not necessarily on the same wall, but so that the unit is not subjected to
continuous spray. Ensuring the shower hose is not kinked or under strain, the shower head should be sited so that it is no more than
610mm (2ft) above the bottom of the unit or no lower than 305mm (1ft) below the unit, when in its normal position in the shower
head holder.

!
Carefully offer the front casing onto the back plate assembly ensuring the wires are not trapped.
Refit the fixing screws and secure the front cover to the backplate.
The control knob, in the fully cold position, may have to be slightly adjusted to enable the
keyways to align.
3
Ensuring the front cover is fitted correctly, secure the cover to the back plate using the fixing screws,
taking care not to overtighten.
4
Without fitting the shower head, fit the hose washer into the hose and attach to the shower outlet
to allow the water to discharge safely to waste.
5
Turn the flow control knob to ensure it moves smoothly. If not, the knob may be fitted incorrectly. The shower should be
commissioned with the knob in the mid position (12 o’clock).
6
If installing Vitalise S model, set the power/heat setting to low.
7
Turn on the electrical isolation switch and press the start stop button.
!
14
The Vitalise SLX LCD screen on the shower unit will display 3 dashes.
8
Select the low power/heat setting. (Refer to the separate user guide booklet).
9
Slowly turn the flow control knob towards the hot direction. The heater elements should now be hotter and the temperature
of the spray should increase.
10
Adjust the flow control knob to provide the desired temperature. Allow a few seconds after each adjustment for the
temperature to stabilise. A cool shower can be achieved with the flow control knob set towards the cold direction.
The temperature achieved will depend on the incoming water temperature, pressure and power setting.
11
Repeat the above procedure with the other power/heat settings.
12
Remove the labels from the front cover of the fitted unit ensuring the model and bar code label located under the unit
remain in place.
Handset to hose assembly
1
Pass the hose through the hose restraint (if required). Ensuring the hose washer is in the
correct position, connect the hose to the handset, taking care not to overtighten and place
into position within the handset holder.
Thermal trip
The Thermal trip cut out will operate with extreme water temperatures. Power to the heater element(s) is cut when the trip operates.
Power restores when the water is cold enough to reset the trip. Unless the temperature dial is adjusted, or other cause of high
temperature is eliminated, the element(s) will continue to cycle on/off and the temperature will cycle hot and cold. Temperature
reduces, but the heat setting knob (Vitalise S) / button indicator (Vitalise SL & SLX) remains at its set position.
Electronic cut out
Vitalise SL and SLX include a 2 stage electronic cut out feature.
Stage 1
If a high water temperature is sensed, the unit will automatically switch down one heat setting until a comfortable temperature is
reached. This procedure repeats every few seconds if the temperature is still too high and may include cycling from High > Medium >
Low > Cold.
After use, if the power to the shower is NOT isolated, the last used heat setting (determined by the Electronic cut out) will be
automatically applied.
If power to the shower IS applied after use, at next operation, the shower will start in default, COLD heat mode.
Stage 2
If an extreme water temperature is sensed, the unit will flash all heat setting button lights (Vitalise SL) / LCD screen flash red, stating
“Over heat” (Vitalise SLX) and will automatically shut the heater element(s) down. Cold water will flush through the unit before
turning the water off. All lights will remain illuminated (Vitalise SL) / The LCD screen will display fault message E2
(Vitalise SLX) with the Start/stop button pushed in to indicate the unit is in fault mode. The lights and error message will
15
remain on and the unit in fault mode until the Start/stop button is pressed to turn the unit off.

Please refer to the separate user guide booklet provided.
After installation
Inspection & maintenance
In the interest of safety, we recommend the Vitalise range and its electrical installation are checked by a qualified electrician
at least every 2 years.
After installation
Familiarise the end user with the Vitalise product operation and hand them this guide.
Complete and post the Vitalise guarantee card and optional guarantee extension agreement document.
Cleaning and maintenance
Your Vitalise product should be cleaned using only a soft cloth and washing up liquid.
DO NOT USE ABRASIVE CLEANERS.
To reduce the requirement for chemical descaling in hard water areas, the shower head incorporates rub clean teats. Any scale
build up that may occur in any of the holes can be broken down by gently rubbing the flexible tips of the jets during use. This
procedure should be completed regularly, as often as once a week in some hard water areas as scale build up can affect the
spray pattern and cause the shower to perform poorly. Failure to descale the shower head can affect the internal seals and may
affect the warranty.
Should chemical descaling of the head become necessary, remove the shower head and fully immerse in a mild proprietary
descalent.
! IT IS IMPERATIVE THAT DESCALING IS CARRIED OUT STRICTLY IN ACCORDANCE WITH THE MANUFACTURERS
INSTRUCTIONS. SUBSTANCES THAT ARE NOT SUITABLE FOR PLASTICS AND ELECTROPLATED SURFACES MUST
NOT BE USED.
Cleaning the filter
Cleaning the filter should only be completed by a competent person.
1. Turn the power supply to the shower off at the consumer unit or mains fuse board.
2. Isolate the water supply to the shower.
3. Remove the fixing screws from the front cover, detach the solenoid connector(s)
and pull the front cover clear.
4. Unscrew using a large flat bladed screwdriver if required and remove the
filter assembly from the shower unit inlet.
! For rear and bottom fed inlet connections, it may be necessary to remove the unit
from the wall.
5. Clean the filter assembly as necessary.
6. Refit the filter assembly and protective cover. Reassemble the unit in reverse
16
of the above procedure.
Trouble shooting guide
! These checks must only be performed by a competent person.
Warning! There are no user serviceable components beneath the cover of the appliance.
IF YOU ARE UNABLE TO REMEDY THE PROBLEM WITHOUT REMOVING THE COVER, YOU SHOULD CONTACT YOUR
INSTALLER OR A QUALIFIED ELECTRICIAN.
Only a competent tradesperson should remove the front cover.
!! The electrical supply to the shower MUST BE isolated at the consumer unit (fuse board) prior to the front cover
being removed!!
Where the fault cannot be corrected by yourself or your installer, DO NOT REMOVE THE UNIT FROM THE WALL, but
contact the Customer Services Department, who will provide assistance over the telephone. If necessary, they can
arrange a visit by a service engineer. We find the vast majority of problems can be resolved by reference to these
fitting instructions or by discussion over the telephone. In the event an engineer is called and the fault is caused by
faulty installation, usage or lack of reasonable maintenance, a call out charge will be made.
Pressures
To ensure optimal performance and that the shower is working to specification:• Try reducing the flow rate (increasing demand temperature) to increase dynamic pressure and selecting the
appropriate heat setting to give required showering temperature.
• Check inlet requirements (see Important Information - Pressures section).
• Ensure no other main water devices are being used whilst showering (e.g. toilet, garden hose, washing
machine, etc).
• Check pipework for potential blockages/pressure losses.
• Ensure the stop cock and servicing valves are fully open. Ensure full bore isolation valve has been fitted.
• Check with the local water authority to check the running pressure is above the minimum required (see
Important Information – Pressures section). This may be apparent during periods of high demand or when
other outlets are used.
IF YOU ARE UNABLE TO REMEDY THE PROBLEM WITHOUT REMOVING THE COVER, YOU SHOULD
CONTACT YOUR INSTALLER OR A QUALIFIED ELECTRICIAN.

select too hot a temperature, the safety temperature switch
inside the shower will turn off the heater elements until a
suitably lower temperature is reached. If this happens turn
the knob anti-clockwise (towards cold) to increase flow and
adjust power setting as required.
