In Order To Maintain The Performance OfYour Shower
You Must Clean The ShowerHead Regularly.
All watercontains particles of lime-scale,which build up in the showerhead and unit reducing the
performance.
Itistherefore important toclean the showerhead by simply rubbing the
rubber nozzles or soaking in proprietary lime-scale remover and rinsing
thoroughlybefore use.
The frequencyof thiswillvaryfrom weeklyto quarterlydepending on the
water hardnessand experience.
In somewinter conditions, when theincoming mainswater isparticularly cold
it maybenecessarytoselect the innerorouter spray pattern only; this will
ensure correctoperation of the showerwitha slightlylowerwater flow rate.
Afteruse it isnormal for some water todrip from thesprayhead fora few
moments. Thishelpsprevent scale build up over prolonged use.
Routine Maintenance
Itisrecommend that as well as checking the showerhead asdetailed above, the shower unit,riser
rail,hose etc. be cleanedusing a soft cloth and that the use of abrasiveorsolvent based cleaning
fluid be avoided, especiallyon any plated finishes.
Werecommend thatbeforeany cleaning, the isolating switch be turnedoff, thus avoidingaccidentally
switching on the shower.
You Must Regularly Inspect The Shower Hose For Wear And Damage.
Replace If Necessary,Or Every Two Years, WithOur Approved Part.

b) Plumbing
Werecommend thataWRAS (WaterRegulations AdvisoryScheme) listed isolatingvalve befitted
between the risingmain and the unit.
Thiswill allowthe unit to be serviced withouthaving to turnoff the housewater at thestop valve.
The unit should be connected to themains cold watersupply. This musthave a minimum running
pressureof 0.07 MPa (0.7bar /10 p.s.i.)and a maximum pressure of 1MPa(10bar /145 p.s.i.)
The unit can befed from a header tank provided this has aminimum headof 7 metres(23ft).
Standard Ø15mm copper or stainlesspipe should be used. Connection to the unit isviaa Ø15mm
plainshankon thesolenoid valve.Acompressionelbow orpushfit connector can be used.
(Stainlesspipe isnot recommendedfor push fit).
Using anIsolating valve, flushthe pipe work through to
removeparticles etc., before making the final connection to
the shower.A blockage in the waterways(particularlythe spray
plate and solenoidvalve)will prevent the unit from working
correctly.
The shower is designed tohavean open outlet and should only
be used with the fittingsrecommendedbythemanufacturer.
Warning!!Do Not FitATapOn The ShowerOutlet.
Take Care ToAvoid RestrictingThe OutletOfThe
Pressure ReliefDevice. (See fig.8forlocation)
c) Electrical Connections
The electrical installation must be in accordancewiththe
current BS7671(I.E.E. wiring regulations)
and “PartP” of the Building Regulations and/orlocal
regulations.
The unit isdesigned fora singlephase50 Hz a.c. electrical supply.
Please check the ratingplate on theunit to see whatdetailsapplyto
yourunit.
A meansfor disconnection inall poles mustbe incorporatedin the
fixedwiring in accordance withthe wiring rules.

Installation Instructions
ALL WIRING AND INSTALLATION
MUSTBE SUPERVISEDBY A SUITABLY QUALIFIEDPERSON.
Werecommend thatthe installation be done in the following sequence: -
a) Fix theshowerto the wall
b) Plumbing
c) Electrical connections
d) Commissioning
Warning. Do Not Install The ShowerIn ARoom WhereIt MayBeSubject ToFreezing
a) Fix TheShowerTo The Wall
When deciding where to place the unit afew things need to be takenintoconsideration: -
1) The unit mustnot be mounted directly in the path of the sprayfrom thehandset
2) The handset could be used over a sink for hairwashing.
3)
The handset does not come into contact with the used waterin the cubicle, bath or basin.
A hose retaineris supplied with the accessories (see separate instructions supplied with
accessories).
4) Choose a flatpiece of wall to avoid thepossibility of distorting the backplate and making the
front cover a poor fit.
Remove the three cover screwsand liftthecoveroff.
Remove side sectioncomplete with seal.
Depending on which water entryisbeing used (top orbottom)
break outthe relevant rearsupport rib using a pair of pliers.
(Seefig.9)
Identify whichpipe and cable entryneedsto be cut toenable
the services toenter the shower (top or bottom, no trimming
required forrear entry) then fit them to the backplate.
(Seefig.9)
Hold the shower verticallyagainstthe wall and markthe top
hole first.
Drill the hole totake therawl plug provided(taking care to keep
dust awayfrom the shower).
Put the topscrew in first leavingit proudby5mm approx.

How Your ShowerWorks
1. Wateris heated
instantaneously as it
flows overthe heatersin
the plasticheat
exchanger assembly.
2. The shower
automaticallyadjuststhe
powerto the heating
elements and flow of
water toachieve the
selected water
temperature.
The electronicssenses
the incoming water
temperature and the flow
of water through the heat
exchanger. It then works
out how many heaters to
switchon so that the
showertemperature
matches the temperature
selected bythe buttons.
3. The amountof hot water
available at the selected
temperature is limited by
the total power of the
heater. Theideal flow
rate iscalculatedand
adjusted automatically.
4. The wateris turned on and off bythe solenoid valve built into the shower.
5. A stabiliserisbuilt into the flow valvetoautomaticallycompensate for small fluctuations in
water pressure that frequentlyoccur in households.There are three further controls to cater for
exceptional reductions in water pressure to preventtheshowerfrom gettingtoo hot.
a) If the flow of water is less than 1.0 l/minthe powerto the elements is switched off, but the
solenoid valve remains open allowing water toflow through the shower.
b) If the outlet temperature sensor sensesan excessivetemperature the flow of waterand the
heating elements will automaticallyswitch off. The electronics willsignal over temperature
condition (see “over temperature shutdown” section).
c) Atwostage mechanical thermal cut-outis mounted on the top of the heat exchanger
independentof the electronics. Stage one switches the power off to the elements if it
senses an excessive temperature.The switchoperates withan audible clickand willreset
if cold wateris run through the shower. Stage two only operatesif an extremetemperature
is sensed.The cutout willpermanently switchoff and it will then have tobe replaced.
6. A pressure relief device is fitted to safeguard againstother extreme conditions,and provides a
level of appliance protection should an excessive build of pressure occurwithin the shower.
If thisoperates a replacementpart willbe required.
