Howto use your Shower
1. Ensure the electricityand water areturned on to the unit.
2. Function of buttons: -
Button “A” –Startsshoweron “high” giving maximum power.
Button “B” – Startsshoweron “medium” giving an economysetting.
Button “C” – Startsshoweron “cold” giving waterwith no heating.
Button “D” – “stop” switches the shower off and coolsthe waterautomatically.
Your shower has3 power settings selected bypushingthe corresponding button on thefront cover.
It can be started bypressing “A”, “B” or“C” buttons.
Once pressed, alight will illuminate next to the button confirmingthat powerselection has been made.
3. Once either “A”(high) or “B”(med) button has been pressed, you will need to adjust the temperature of the water.
This isdone byrotating knob “E”.Turn the knob until 3 lights illuminate on the arc.
Allow20 seconds forthe temperature to settle. If it istoo lowthen turn the knob anti-clockwise in the direction of
the “red arrows”, allow another 20 seconds. Repeat this procedure until the temperature is toyourliking.
4. If the temperature istoo high then turn knob "E" clockwise in the direction of the “Grey (or Black) arrows” allowing
20 secondsbetween adjustments. The final adjustment can be anywhere on the scale.
Summarising:Clockwise Lowers temperature (less lights)
Anti-Clockwise Raises temperature (more lights)
The more lights that are illuminated, the hotterthewater coming out ofthe handset.
The radial lights indicate the position of the flow knob in its travel
i.e. all lightson – valve fullyanti-clockwise (minimum flow). Alllights off – valve fullyclockwise (maximum flow).
See diagram 3 forrelationship of flow to temperature.
Once a temperaturesetting to your liking has been achieved, knob “E” will rarelyneed adjusting,
eg: adjust for variations of incoming mainswater temperature between summer and winter.
5. When you have finished showering,push button “D”only. The electricityto theelements is then disconnected and
the adjacent lightswill flash. Waterwill continue to flow for approximately5 secondsbefore switching off.
This reduces the temperature of the water in the tank for the next user.
Switch off the electricityat the ceiling switch or local isolator.
6. Your shower is designed to stabilise temperature changescaused bywaterpressure fluctuations. These can
result from toilets being flushed or taps being turned onand off. When thishappensyour showering temperature will
be held within a controlled band, providedthat the minimum pressure required bythe shower is maintained.
7. Your shower requiresa minimum operating pressure of69kPa(0.7 bar, 10 psi). At pressuresabove 69kPa
(0.7 bar, 10 psi) it will minimizestemperature fluctuationsasdetailed above in note 6. If the waterpressure falls
below69kPa (0.7 bar, 10 psi) it islikelythat the pressure switch willturnoff the power to the heating elements,
resulting in a cold shower.
The “lowpressure” light will illuminate and the “overheat” light maycome on to indicate thishas happened.
8. During normal operation if an overheated watertemperature issensed bythe showerthen the thermal cut-out will
switch offthe heating elements. The “overheat” lightwill illuminate to provide a visual indication that this hastaken
place. Water will continue to flowand as the watertemperature falls the heatingelements willbe turned backon. If
the “overheat” light continuesto cycle then increase the water flowrate byturning knob “E” clockwise and check
that the handset does not require de-scaling. If the “overheat” light still continues to cycle, then pressbutton “B” to
the “medium” power setting (knob “E” will need adjusting).
9. Note that knob “E” ISNOTATAP and doesnot turn the water off.
WARNING:DO NOT SWITCH THE SHOWER ONIF YOU SUSPECT IT OF BEING FROZEN.
WAIT UNTIL YOUARESURE ITHASTHAWED OUT

Howyour ShowerWorks
Your shower is designed for convenience, economy and safetyof use.
1. Water isheated instantaneouslyasit flowsover the heating elementsin thecopper cylinder (diagram2)
2. The required water temperature is achieved byadjusting the rate of water flow.
Diagram 3shows the principle involved in relating temperaturerise to flow rate.
The higherthewater rate the lowerthe temperature rise and vice versa.
The temperatureof the water supplied from the mainscan varyconsiderably
throughout the year from 5 to 20°C.
Thismeans that in the winter, flowrate will be lessthan in the summer to
achieve the same outlet temperature.
In summer the “medium” powersetting maygive adequate hot water.
3. The heatersare onlyswitched on when sufficient wateris flowing.
Thisis done automaticallybya switch which works on water pressure.
4. The water is turned on and off bythe solenoid valve built into the shower.
Thisis switched on bybutton “A”, “B” or “C”.
5. The flowof water isautomaticallyheld at the level set bythe usereven though the supplypressuremayvary
(See “How to use yourshower” note 6).
6. If the water supplyfalls belowa setlimit, the pressureswitch will operate andswitch off the power to the elements.
Thisis indicated bythe “lowpressure” light illuminating (see “How to use yourshower”note 7).
7. Asa further safeguard, a thermal cut-out switches the power off if the water temperature climbsabove the set limit
and the “overheat” light will come on.
Thiscut-outgives an audible click when switching off, but will reset itself if water isrun through the shower for 10 to
20 seconds,and the “overheat” light willgo out.
8. The pressure relief device isto safeguardagainst extreme abuse conditions.
Howto maintain your Shower
It isrecommend that the showerunit, riser rail, hose etc. be cleaned using a soft cloth and that the use of abrasive or
solvent cleaning fluid be avoided, especiallyon anyplated finishes.
Werecommend that before anycleaning, the isolating switch be turned off, thusavoiding accidentallyswitching on the
shower. INORDERTO MAINTAIN THE PERFORMANCE OF YOUR SHOWER,
YOU MUST CLEAN THE SHOWERHANDSET REGULARLY
All water contains particle
sof lime, which build up in the showerhandset and unit reducing the performance.
It istherefore important to clean the shower handset bysimplyrubbingthe rubber nozzles.
In some winter conditions,when the incoming mains wateris particularlycold it maybe necessaryto selectthe inner or
outer spraypattern only.
Thiswill ensure correctoperation of the shower with a slightlylowerwater flow rate.
NOTE: Afteruse it is normal forsome water to drip from the
shower handset for a few moments.
This inhibits scale build-upoverprolonged use.

What to do if thingsgo wrong
SELF HELP
If the shower is unsatisfactory,make the following checksbefore calling out the contractor.
Anyone ofthese adjustments could restore the performance.
a)The shower cycles
from HOT to COLD The showertemperatureisset too hot causing the thermalcut-out (safetydevice) to operate. Turn knob “E” clockwise in the direction of the “Grey (or Black) arrows
” to increase water flow.
“Medium”setting mayneed to be selected.
Slowlyincrease the water temperature byturning knob “E” anti-clockwise in the direction of
the “red arrows”until a comfortable showering temperature hasbeen reached.
You MUST WAIT approx. 20 seconds for each adjustment to affect the water temperature.
b)Water too HOT Increase water flow byturning knob “E” clockwise in the direction of the “Grey or Black arrows”.
Clean shower handset holes. Select outer or combination spraypattern.
Switchpower to “medium” setting.
Increase pressure to watersupplye.g. fullyopen service valve or stop cock.
Check hose isnot kinked restrictingthewater flow.
c) Watertoo COLD Decrease water flow byturning knob “E” anti-clockwise in thedirection of the “red arrows”
Switchpower to “high” setting. Select inner orouter shower handset spraypattern only.
d) Spraypattern poor Clean shower handset and flush heater. Select outer/inneronly.
e)Water goescold
while using
shower
Check powersetting lightsare on.
Check water pressure has not fallen so far as to let pressure switch cut out,
e.g. Anothertap drawing water off, indicated by “lowpressure” light on.
Raise positionof shower handset.
f) Broken parts Pleasecontact ourspares department on 0117 923 5375. Fitting instructionsare provided.

Installation Instructions
ALL WIRINGAND INSTALLATIONMUST BESUPERVISEDBYAQUALIFIED ELECTRICIAN
WARNING:DO NOT INSTALLTHIS SHOWER INAROOM WHERE IT MAYBE SUBJECT TOFREEZING.
Werecommend that the installation is done in the following sequence.
a. Fixing the shower to the wall
b. Plumbing
c. Electrical connections
a. Fixing the shower to the wall
1. Position the riser rail at the height recommended in diagram 5 and markitsposition (also see separate accessories
fitting instructions sheet). 2. Position the heater so that the top ofthe unit ishorizontal and level with,
or upto 0.6 metres (2ft)maximum belowthe top of the riser rail.
Choose a flat piece of wall to avoid the possibilityof distorting the
backplate thus making the front covera poorfit.
3. Adjust the position to get the most convenientarrangement taking the
following into account.
•The possible need to use the handset overthe sink for hair washing etc.
•The heater must not be mounted in directspray fromthe handset.
•The handset must not be able to come into contact with used water in the
cubicle, bath orbasin.
If it can, even after the hose hasbeen retained bythe soap dish (see
separate accessories fitting instructions sheet), then avacuum breaker
must be fitted.
It should be noted that these devicesare liable to minor leakageso they
must be positioned so that anydrips are not detrimental.
4. Fixthe riser rail with screws provided (see separate accessories fitting
instructions sheet).
5. Decide the position ofthe electrical cable to the unit.
If top orbottom entryis chosen(according to diagram 4), cut
awaythe walls in the backplate as shown in diagram 6.
6. Decide the position ofentryof the cold water pipe into the unit.
If top, cut awaythe backplate.
If rear, please read the section on plumbing.
If bottom,remove the front cover and cut awaythe detachable
cornersection as shown,
7. If you have not yet done so, remove the front coverof the unit by
undoing the retaining screwsat the top and bottomof the unit
and lifting the cover off.
Your shower isprovided with 2 fixing positions in the backplate
(see diagram 4).
The top-fixing hole is a “key-hole” slot (another key-hole is
provided foralternate fixing), and should be marked and drilled
first.
Tighten top screwwith head protruding about10mm from the
wall and hookthe backplate overthe screw head.
This allowsfor correctand accurate alignment of your shower
before marking and fixing the bottom position.
You maynot wish totighten up both screws at thisstage as
the holes are elongated toallowforadjustment after other
connectionshave taken place.
Diagram 6

b. Plumbing
The heater must be connected to the mains cold watersupply. Thismust havea minimum running pressure of69kPa
(0.7 bar,10 psi)and a maximum pressure of 690kPa (7.0 bar, 100 psi).
Before connecting the pipe work to the shower, ensure thatpipe work is flushedout.
1. It is recommended that a WRAS(Water Regulations AdvisoryScheme) listed isolating valve is fitted between the
rising main and the unit. Thiswill allowthe unit to be serviced without turning off the cold water orexchanged without
having to turn off the waterat the water stop valve.
2. The heatercan be fedfroma header tankprovided this has a minimum head of 7 metres (23ft).
3. Ø15mmcopperor stainlesssteel pipe should be used.
To avoid cross threading, DO NOTREMOVEthe brassnut from the elbow when positioning the pipe.
If top entryis required, turn the elbow 180° into the required position.
If rearentryisrequired, treat astop entrywith an additional “Yorkshire” elbow (soldered type) for fitting into the rear
channel.
In multiple installations, correct pipe worksizesshould be calculated to maintain adequate flowto each shower.
4. It is in order to use a WRAS(Water RegulationsAdvisoryScheme)approved sealant sparinglywhilst avoiding
excess finding itswayinto the shower operating parts.
5. With stop valve connected, flush the pipe work through to remove any particles etc, before making the final
connection to the shower. Blockage in the water ways(particularlythe handset and solenoid valve) will prevent the
heaterworking properly.
6. The shower is designed to have an open outlet and should onlybe used with “Heatstore” recommended fittings.
Do not connect the handsetuntil afterthe shower front cover and corner section are fitted.
WARNING:DO NOT FIT A TAPONTHE SHOWER OUTLET.
TAKE CARE TO AVOIDRESTRICTING THE OUTLET OF THE PRESSURE RELIEF DEVICE
