as detailed in diagram 1 and mark its position.
2. Position the heater so that the top of the unit is horizontal and
level with, or upto 0.6metres (2ft) maximum belowthetop
of the riser rail.
Choose a flat piece ofwalltoavoid the possibilityofdistorting
the backplate, as this maymake the front cover apoor fit.
3. Adjust the positiontogetthe most convenientarrangement
takingthe followinginto account.
•The heater must not be mounted in thedirect sprayfrom
the handset.
•The handset must not be able to come into contact with used water inthe cubicle, bath or basin.
If it can, then a vacuum breaker must befitted.
4. Fixthe riser rail with suitable screws.
The fixing holes at thebase of thebrackets will be disclosed byremoving the
plasticfronts.
(See diagram 9).

How your Creda Shower Works s
Your shower is designed for convenience, economy and safetyof use.
1. Water isheated instantaneouslyas it flows over the heating elements in the copper cylinder (diagram 7)
2. The heaters are onlyswitched on when sufficient water isflowing.
This is done automaticallywith aswitch, whichworkson water pressure.
3. The water is turned on and off bythe solenoid valve
built into the shower.This is switched on bybutton “B”.
4. The flow of water is automaticallyheldat the levelset
by the user even though the supplypressure mayvary.
5. Ifthe water supplyfalls below a set limit, the pressure
switch willoperate switching off the power to the elements.
6. As a further safeguard, a thermalcut-out switches the
power off if the water temperature climbsabove the setlimit.
This cut-out,which gives an audible click, mayalso operate
due to residual heat when the showeris switched off.
Itwill reset itself if water isrun through the shower for
10 to20 seconds.
7. The pressure relief device istosafeguard against safeguard against
abnormal pressure conditions,and provides a level of appliance
protection should an excessive build of pressure occur withinthe shower.
8. The required water temperature is achieved byadjusting the rate of water flow.
Diagram 8 shows the principle involved inrelating temperature rise to flow rate.
The higher the water rate the lower the temperature and vice versa.
The temperature of the water supplied from the mains can varyconsiderably
throughout the year from 5 to 20°C.
Thismeans that in the winter, flowrate willbe less than in the summer to achieve the
same outlettemperature.

What to do if things go wrong r
SELF HELP
If the shower is not working satisfactorily, make the following checks before calling out theinstaller.
Anyone of theseadjustments could restore the performance.
The shower cycles
from HOT toCOLD
The shower temperature is set too hot causing the thermal cut-out(safety
device) to operate.
Turnknob “A” anti-clockwise in the direction of the“cooler arrow” to increase
water flow.
Slowlyincrease the water temperature byturning knob “A” clockwisein the
directionof the “warmer arrow” until a comfortable showering temperature
has been reached.
YouMUST WAIT approx’ 20seconds for eachadjustment toaffect the water
temperature.
Water too HOT
Increase water flowbyadjusting the temperature control anti-clockwise.
Cleanshowerhead holes. Select outer or combination spraypattern.
Increase pressure to water supplye.g. fullyopen service valveor stopcock.
Check hoseisnot kinked restricting the water flow.
Water too COLD Decreasewater flowbyadjusting the temperature controlclockwise.
Select inner or outer patternonly.
Spraypattern poor Cleanshowerhead andflushheater. Select outer/inner only.
Water takes longer
to heat up Thermal cut-out hasoperated after previous use. Will automaticallyreset when unit cools down.
Water goes cold
whileusing
shower
Check power light is on.
Check water pressure has not fallen sofar asto let pressure switchcut out,
e.g. Another tap drawing water off.
Broken parts Please contactour spares department on0844372 7750.
PROFESSIONAL SERVICE
If the above checks fail torestore the performance, you should seek professional help.
The person who installed the shower is probablythe best one to investigate and correct it andis
certainlythe person tocontact if youhave hada problem in the guarantee period.
The following additional checklist is provided for thebenefit of the qualified serviceperson.
WARNING: SWITCH OFF THE ELECTRICITY ATTHE ISOLATING SWITCH
BEFORE REMOVING THE COVER TO MAKE CHECKS
Water too HOT Water flow restricted byblockage in filter of solenoid valve.
Switch offwater, loosen inlet connection to solenoidand clean.
Water tooCOLD Check circuit through thermal cut-out. Check circuit through microswitches on the pressure switch.
Check eachelement circuit. Check tightness of electrical connections.
No control over
water flow Undo headworks ofstabiliser valve. Check stabiliser is inplaceand remove anydebris in valve.
Water discharges
from burst pressure

7. If you have not yet doneso, removethe unit front cover
byundoing the retainingscrews atthe topand bottom of
the unit and lifting thecover off.
Your shower is provided with2fixing positions inthe
backplate (see diagram 3).
Thetop-fixing hole is a “key-hole” slot (another key-hole
is provided for alternate fixing),and should bemarked
and drilled first.
Tighten top suitable screw withhead protruding about
10mm from thewall and hook the backplate over the
screwhead.
Thisallows for correct and accurate alignment of your
shower before markingand fixing thebottom position.
You maynot wish totighten up bothsuitablescrews at
this stage as the holes are elongated to allowfor
adjustment after other connections havetaken place.
b. Plumbing
The heater must be connectedtothe mains coldwater supply.
This must have a minimum runningpressure of 100kPa (1.0 bar, 15psi)
,
andamaximum pressure of 690kPa(7.0 bar, 100 psi).
WARNING: ENSURE PIPEWORK IS FLUSHED OUTBEFORE CONNECTING TO THE SHOWER.
1. Itis recommended that a WRAS (Water Regulations AdvisoryScheme) listed isolatingvalve is
fitted tothe incoming mains cold water before the unit.
This will allow theunit to beserviced or exchanged without having to turn off the water at the
water stopvalve.
2. The heater can be fed from a header tank providedthis has a minimum head of7 metres (23ft).
3. The water
inlet connectionsupplied is a plainØ15mm straight shank/shaft.
This connector will accepteither a Ø15mm compression elbow or a Ø15mm “push-on elbow”.
Ifrear entry is required, anadditional“Yorkshire” elbow(solderedtype) for fitting intothe rear
channel is required.
Ø15mm copper or stainless steel pipe shouldbeused.
In multiple installations, correct pipework sizes should be calculated tomaintainadequate flowto
eachshower.
4. Itis permissible to use a WRAS (Water Regulations AdvisoryScheme) approved sealant
sparinglywhilst avoiding excess findingits wayintothe shower operating parts.
5. Withisolating valve connected, flush the pipework through to removeanyparticles etc,
before making thefinal connection to theshower.
Blockage inthe water ways (particularlythe handset and solenoid valve) will preventtheheater
working properly. Note: You maybe charged for aservice call if itis duetoincorrect installation.
6. The shower is designed tohave an open outlet and should onlybe usedwith “Creda”
recommended fittings.
Do notconnect the handset until after the shower frontcover and corner sectionare fitted.
WARNING: DO NOTFIT ATAP ON THE SHOWER OUTLET.
TAKE CARE TOAVOID RESTRICTING THE OUTLETOF THE PRESSURE RELIEF DEVICE
WARNING: THIS SHOWER IS DESIGNED AND APPROVED TO EN-60335 WITH THE HANDSET
PROVIDED. UNDER NO CIRCUMSTANCES MUST ANY HANDSETTHATIS
NOT APPROVED BY THE MANUFACTURER BE USED WITH THIS PRODUCT.

.
This will turn on theshower, the water will flow, and the
neon indicator light will glow.
Itis recommended that youdo not whollyenter the
water sprayduring this period, especially if theshower
has just been used.
3. If the water is not at your desired showering
temperature, turnthe knob “A” a small amount.
(Anti-clockwise for cooler, clockwise for warmer).
4. To finish showering, press the start / stopbutton “B”
5. Switch off theelectricity supplyat the isolating switch.
6. There are a number of defined sprayplatesettings
adjustable byrotatingthehandset sprayplate.
Notes
•Wait 20 seconds for thetemperature to stabilise after each adjustment.
•The neon indicateswhen theheaters are on and, if the shower has been recently used,
can take up to20 seconds to comeon.
(During thistime the water may gofrom hot to cold before stabilising).
•The knob position will be approximately the same each time the shower isused, varying
only withincoming water temperature or pressure changes(e.g. from summer to winter).
•During normal operation, if an overheated water temperature is sensed then the heater will
switch off andthe neon indicator will goout.
The water will continue toflowandcool down before the heater switches backonagain.
•Knob “A” isnot atap and does not turnthe water off.
WARNING: DO NOTSWITCH THE SHOWERON IFYOU SUSPECTITOF BEING FROZEN.
WAITUNTIL YOU ARE SURE ITHASTHAWED OUT
Howto maintainyour Shower .
Itis recommended that the shower unit andhose etc. be cleaned using a softcloth and that the use
ofabrasive or solvent basedcleaning fluid be avoided, especiallyon anyplated finishes.
Werecommend that before anycleaning, the isolating switch be turnedoff, thus avoiding accidentally
switching onthe shower.
WARNING: YOU MUST REGULARLY INSPECTTHE SHOWER HOSE FOR WEAR AND DAMAGE.
REPLACE IF NECESSARY, OR EVERY TWO YEARS, WITHANAPPROVED PART.
WARNING: IN ORDER TO MAINTAIN THE PERFORMANCE OFYOUR SHOWER,
YOU MUST REGULARLY CLEAN THE SHOWER HANDSET.
All water contains particles of lime-scale, which build up in the shower handset and
unit reducing the performance.
Itis therefore important tocleanthe handsetby simply rubbing the rubber nozzles or
Soaking inproprietarylime-scale remover and rinsing thoroughly (handsetmayvary).
Note: After use it is normal for somewater to drip from the shower handset for a
fewmoments. This inhibits lime-scale build-up over prolonged use.
