Howto use your Shower
1. Ensure the electricityandwater are turned on to the unit.
2. Your shower has 3 power settings selected byturning knob “A”.
The most popular is “FULLHEAT” indicated by“ ” and for your convenience this can be obtained in 2 positionsso
you are always onlyone step awayfrommaximumpower.
There are alsooptions for a “HALF HEAT” or “COLD” shower (see notes 8 and 9).
For this example turn knob “A” to “FULL HEAT” (either will do) and set knob“C” to “6 o’clock” on thescale.
3. Press button “B”. Water will flow,3 lights will illuminate to indicate that the selected power rating is “FULL HEAT”.
4. Allowabout 20 seconds for the temperature ofthe water to stabilise. It is recommended that you do not wholly
enter the water sprayduring this period, even ifthe shower has just been used.
5a. Ifthewater is too hot,thenincrease the flowof water by turning knob “C” clockwise to “7o’clock” on the scale.
Wait 20 seconds
for thetemperature ofthe water to stabilise.
Repeat turning clockwiseifnecessaryuntil yougetthe water temperature of your liking.
5b. Ifthewater is too cold, turn knob “C” anti-clockwise to “5 o’clock” on the scale and continue as necessaryuntil
you get thewater temperatureof your liking. The final adjustment maybe anywhere on the scale.
5c. Basically turningknob “C” anti-clockwise increases
the water temperature,
whilst turning clockwise decreases the water temperature.
6. Once a temperature settingto your liking has been achieved,knob “C” will rarelyneed adjusting,
eg: adjust for variations ofincoming mains water temperature between summer and winter.
7. When you have finished showering,push button “B” only.You have no needtoadjust knobs “A” or “C”.
Switchoff the electricityatthe ceiling switch or local isolator.
8. The “HALF HEAT ” settingofknob “A” reduces the power used bythe shower giving a cooler shower or the option
ofreduced water flow. This option is mainlyfor summer usage andifthis is used then knob “C” must be
re-adjusted. Onthis setting 2 lights will illuminate to indicate that the selected power rating is “HALF HEAT”
9. The “COLD” setting indicated by“ ” ofknob “A” will supplywater without anyheating, and only1 lightwill
illuminate to indicate this.
10. Your shower is designed to stabilise temperature changes caused bywater pressure fluctuations. These can
result fromtoilets being flushed or taps being turned onand off.When this happensyour showering temperature will
be held within a controlledband, providedthat the minimumpressure required bythe shower is maintained.
11. Your shower requires a minimumoperatingpressure of69kPa (0.7 bar, 10 psi). At pressures above 69kPa
(0.7 bar,10 psi) it will minimizes temperature fluctuations as detailed above in note 10. Ifthe water pressure falls
below69kPa (0.7 bar, 10 psi) it is likelythat the pressure switch will turnoff the power to the heating elements,
resulting in a cold shower. The 2 middle power indication lights will flicker and go out and the “OVERHEAT” light
maycome on to indicate this has happened.
12. During normal operation ifan overheated water temperature is sensed bythe shower then the thermal cut-out will
switch off the heating elements. The “OVERHEAT” light will illuminate to providea visual indication that this has
taken place.Water will continue to flow and as the water temperature falls the heatingelements will beturnedback
on. Ifthe “OVERHEAT” light continues to cycle then turn knob “A” to the “HALF HEAT ” power setting (knob “C”
will need adjusting). Iftheshower is operatedafter it has recentlybeen usedthe“OVERHEAT” light mayilluminate
for a fewseconds. This indicates thatthereis still some hot water left in the shower.
Either, wait a fewmoments for the lightto go out or turn knob “C” clockwise.
13. Note that knob “C” IS NOTATAP and does not turn thewater off.
WARNING: DO NOTSWITCH THE SHOWERON IF YOU SUSPECTITOF BEING FROZEN.
WAITUNTIL YOU ARE SURE ITHAS THAWED OUT

Howyour ShowerWorks
Your shower is designed for convenience, economy and safetyof use.
1. Water is heated instantaneouslyas it flows over the heating elements inthecopper cylinder (diagram2)
2. The requiredwater temperature is achieved byadjusting the rateofwater flow. Diagram3
shows the principle involved inrelating temperature rise to flow rate. The higher thewater
rate the lower the temperature rise and viceversa. The temperature ofthewater supplied
fromthe mains can varyconsiderablythroughout theyear from5 to 20°C. This means
that in the winter, flowratewill be less than in the summer to achieve the same outlet
temperature. In summer the “HALF HEAT” power setting maygive adequate hot water.
3. The heaters are onlyswitched onwhen sufficient wateris flowing.
This is done automaticallywith a switch which works on water pressure and is indicated by2 or 3 lights illuminating
depending on knob “A” power selection.
4. The water is turnedon and off bythe solenoidvalve built into the shower. This is switched onbybutton“B”.
5. The flowof water is automatically held at the level set bythe user even though the supplypressure mayvary
(See “How to use your shower” note10).
6. Ifthe water supplyfalls belowa setlimit, the pressure switch will operate andswitch off the
power to the elements. This is indicated bythe middlepower settinglights flickering and
going out (see “Howtouse your shower” note 11).
7. As a further safeguard, a thermal cut-out switches the power off ifthe water temperature
climbs abovetheset limit and the “OVERHEAT” light will come on.
This cut-out, which gives an audible click,mayalso operate due to residual heat when the
shower is switchedoff. It will resetitselfifwater is run through the shower for 10 to20
seconds, and the “OVERHEAT” light will go out.
8. The pressure reliefdevice is to safeguard against abnormal pressure conditions, and
provides a level ofappliance protectionshould an excessive build up ofpressure occur
within the shower.
9. There are a number ofdefined sprayplate setting modes (patterns) adjustable byrotating
the sprayplate (see diagram4).
These modes (patterns) have a positive clickto identify them.
The sprayplaterotates through a full circle (360°) in either direction.
IN ORDERTOMAINTAIN THE PERFORMANCE OF YOUR SHOWER,
YOU MUSTCLEAN THE SHOWERHEADREGULARLY.
All water contains particles of lime-scale, which buildup intheshowerhead and unit reducing
the performance. It is therefore important to clean the showerheadbysimplyrubbing the
rubber nozzles, or soaking in a proprietarylime-scale remover and rinsing thoroughlybefore
use.
NOTE: After use it is normal for some water todrip fromthe showerhead for a fewmoments.
This inhibits lime-scale build-up over prolonged use.

What to do if things gowrong
SELF HELP
If the shower is notworking satisfactorily, make the following checks be
fore calling outthe contractor.
Any one ofthese adjustmentscould restore the performance.
a) The shower cycles
from HOT to COLD The shower temperature is settoo hot causing the thermal cut-out (safety device) to operate.
Turn the temperature knob fully clockwise to increase the water flow.
“HALF HEAT ” setting may need to be selected.
Slowly increase the water temperature by turning knob anti-clockwise until a comfortable showering
temperature has been reached.
You MUSTWAIT approximately 20 seconds for each adjustment to affect the water temperature.
b) Watertoo HOT Increase water flowby adjusting the temperature control clockwise.
Clean showerhead holes. Select outer or combination spray pattern.
Switch power to “HALF HEAT ” setting.
Increase pressure to water supply e.g.fully open service valve or stop cock.
Check hose is not kinked restricting the water flow.
c) Water too COLD Decrease water flowby adjusting the temperature control anti-clockwise.
Select inner orouter pattern only. Switch power to “FULL HEAT ” HIGH” setting.
d) Spray pattern poor Clean showerhead and flush heater. Select outer/inner only.
e) Watertakes longer
to heat up Thermal cut-out has operated after previous use (“OVERHEAT” light is on). Will automatically reset when unit cools down.
Switch power to “FULL HEAT ” setting.
f) Water goes cold
while using
shower
Check power setting lights are on.
Check water pressure has not fallen so far as to let pressure switch cut out,
e.g. Anothertap drawing water off. Raise position of handset.
g) Broken parts Contact our spares department on 0844 372 7750. Fitting instructions are provided in most cases.
PROFESSIONAL SERVICE
If the above checks fail to restore the performance, you should seek professional help.
The person who installed the shower is probably the bestone to investigate and correct it, and is certainly the person to contactif you
have had a problem in the guarantee period.
The following additional checklist is provided for the benefit ofthe qualified service person.
WARNING:SWITCH OFF THE ELECTRICITY AT THE ISOLATOR BEFORE REMOVING THE COVER TO MAKE CHECKS
a) Watertoo HOT Water flowrestricted by blockage in filter ofsolenoid valve.Switch off water, loosen inletconnection
to solenoid,remove filter in solenoid with long nosed pliers and flush clean.
b) Watertoo COLD Check circuit through thermal cut-out.
Check circuit through microswitches on the pressure switch.
Check each element circuit.
Check tightness of electrical connections.
c) No control over
water flow Undo headworks of stabiliser valve. Check stabiliser is in place and remove any debris in valve.
d) Water discharges
from pressure
relief valve
Check for cause of high pressure and remove it.
Blockage on outlet e.g. blocked showerhead.
Replace the pressure relief disc (notcovered by guarantee).
e) Waterdoes not flow
when button “B” is
pressed.

Installation Instructions
ALL WIRING AND INSTALLATION MUSTBE SUPERVISED BY AQUALIFIED ELECTRICIAN
WARNING: DO NOTINSTALL THIS SHOWER INAROOMWHERE ITMAYBE SUBJECTTO FREEZING.
Werecommend that theinstallation is done in the followingsequence.
a. Fixing the shower to thewall
b. Plumbing
c. Electrical connections
a. Fixing the shower to the wall
1. Positiontheriser rail at a convenientheight for majority ofusers as detailed in diagram6 and markits position
2. Positiontheheater so that the top oftheunit is horizontal and levelwith,or up
to 0.6 metres (2ft) maximum belowthe top of the riser rail.
Choose a flat pieceofwall to avoid the possibilityofdistorting the backplate thus
making the front cover a poor fit.
3. Adjust the position to get the most convenientarrangement taking the following
intoaccount.
•The possible need to use the handsetover the sinkfor hair washing etc.
•The heater must not be mounted in the direct spray from the handset.
•The handset must not be able to come into contact with used water in the
cubicle, bath or basin. Ifit can, even after the hose hasbeen retained bythe
soap dish (see diagram11), then a vacuumbreaker must be fitted.
It should be noted that these devices are liableto minor leakage so they
must be positioned so that anydrips are not detrimental.
4. Fix the riser rail with screws provided. The fixingholes at the baseofthe
brackets will be disclosed byremoving the plastic fronts. Assemble as shownin
diagram11. Additional “knock-out” slots are available ifrequired to improve
security. The soap dish has a removable insert for ease ofcleaning.
5. Decidetheposition ofthe electrical cable to the unit.
Iftop or bottomentryis chosen (according to diagram5),
cut away the walls in the backplate as shownin diagram7.
6. Decidetheposition ofentry ofthe cold water pipeinto the unit.
Iftop, cut awaythe backplate.
Ifrear, please read the section on plumbing.
Ifbottom, remove thefront cover (complete with knobs) and cut awaythe
detachable corner section as shown,
7. If you have not yet done so, remove the front cover (complete with knobs)
ofthe unit byundoing the retaining screws at the top and bottomofthe
unitand lifting the cover off.
Your shower is provided with 2 fixing positions in the backplate (see
diagram5).
The top-fixing hole is a“key-hole” slot (another key-hole is provided for
alternate fixing), and should be marked and drilled first.
Tighten top screwwith head protruding about10mmfromthe wall and
hookthe backplate over the screwhead.
This allows for correct andaccurate alignment of your shower before
marking and fixing the bottomposition.
You maynot wish totighten up both screwsat this stage as the holes are elongated toallow for adjustment after
other connections have taken place.

b. Plumbing
The heater must be connected to the mains cold water supply. This must have a minimumrunning pressure of69kPa
(0.7 bar,10 psi) and amaximumpressure of690kPa (7.0 bar, 100 psi).
Before connecting the pipe work to the shower, ensure that pipework is flushed out.
1. It is recommended that a WRAS (Water Regulations AdvisoryScheme) listed isolatingvalveis fitted to the incoming
mains cold water before the shower unit.
This will allow theunit to beservicedor exchangedwithout having to turnoff the water atthe water stop valve.
2. The heater can befed froma header tankprovided this has a minimumhead of7 metres (23ft).
3. Ø15mmcopper or stainless steel pipe should be used.
To avoid cross threading, DO NOTREMOVE the brass nut fromthe elbowwhen positioning the pipe.
Iftop entryis required, turn the elbow180° into the required position.
Ifrear entryis required, treat as top entrywithan additional “Yorkshire” elbow (soldered type) for fitting into the rear
channel.
In multiple installations, correct pipeworksizes shouldbe calculated to maintain adequate flow to each shower.
4. It is permissible to usea WRAS (Water Regulations AdvisoryScheme) approved sealant sparinglywhilst avoiding
excess finding its wayintothe shower operating parts.
5. With isolating valve connected, flush thepipe work through to remove anyparticlesetc,before making the final
connection to the shower. Blockage in the water ways(particularlythe handset and solenoid valve) will prevent the
heater working properly. Note: Youmay be charged for a service call if it is due to incorrect installation.
6. The shower is designed to have an open outlet andshould onlybeused with manufacturer recommended fittings.
Do not connect the handsetuntil after the shower front cover and corner section are fitted.
WARNING: DO NOTFIT ATAP ON T
HE SHOWER OUTLET.
TAKE CARE TOAVOID RESTRICTING THE OUTLETOF THE PRESSURE RELIEF DEVICE
