1. Water is heated instantaneously as it flowsover the
heating elements inthe copper cylinder (Diagram 8).
2. Theheaters are only switched onwhensufficient
water is flowing.
This is done automatically witha switchwhich
works onwater pressure and is indicated by the
neonlight illuminatingdependingonthe power
selected by outer knob “A”.
3. Thewater is turned onand off by the solenoid
valve built intothe shower.
This is switched onwhenouter knob “A” is
clicked clockwise.
4. Theflowof water is automatically held at the level
set by theuser eventhoughthe supplypressure mayvary
(see “Effect of Other Water Devices onIncomingWater Supply”).
5. If the water supplyfalls below a set limit, the pressure
switchwill operate and switchoff thepower tothe elements.
This is indicated by the neonlight goingout (see “Effect ofOther Water Devices onIncoming
Water Supply”).
6. As a further safeguard, a thermal cut-outswitches the power off if thewater temperature
climbs above the set limit. This cut-out, whichgives anaudible click,may also operate due to
residualheat whentheshower is switched off.
It will reset itselfifwater is runthroughthe shower for 10 to20 seconds.
7. Thepressure relief device is tosafeguard against abnormal pressure conditions, and provides a
level ofappliance protectionshould anexcessive build ofpressure occur withinthe shower.
Effectof Seasonal Incoming Water Temperature Changes
The required water temperature is achieved by adjustingtherate ofwater flow.
Diagram 9 showsthe principle involved inrelating temperaturerise toflowrate.
The higher the water rate the lower thetemperature and vice versa.
The temperature of the water supplied fromthe mainscanvary considerably
throughout the year from5 to20°C.
This means that inthe winter, flow rate will be less thaninthe summer to
achieve the sameoutlet temperature.
In some summer conditions, the “ (medium)” power setting may give adequate hot water.
Insome winter conditions, it may be necessaryto select the inner or outer spray pattern only of
your shower handset. This will ensure correct operationof theshower witha slightlylower flow rate.
Effectof Other Water Devices on Incoming Water Supply
Yourshower is designedto stabilise temperature changes caused bywater pressure
fluctuations. These canresult fromtoilets beingflushed ortaps beingturned onand off.
Whenthis happens your showeringtemperature will be held withinacontrolled band, provided that
the minimum pressure required by the shower is maintained.
Yourshower requires a minimum running
pressure of 69kPa (0.7 bar, 10 psi).
At pressures above 69kPa (0.7 bar, 10 psi) it willminimise temperature fluctuations as detailed
above. If the water pressure falls below 69kPa (0.7 bar, 10 psi) it is likely that the pressure switch
willturnoffthe power tothe heating elements, resulting ina cold shower.
This will be indicated bytheneonlight goingout.

WARNING: ALLWIRING AND INSTALLATION MUST BE
SUPERVISEDBY ASUITABLYQUALIFIED PERSON.
WARNING: DO NOT INSTALL THIS SHOWER WHERE IT MAYBE
SUBJECTED TOFREEZINGCONDITIONS
We recommend that the installationis done inthe following sequence.
a. Fixing the shower to the wall b. Plumbing c. Electricalconnections
a. FIXING THESHOWER TO THE WALL
1. Positionthe riser rail at a convenientheight formajority of users as
detailedin Diagram1 and mark its position (alsosee separate
accessories fitting instructions).
2. Positionthe heater sothat the top of theunit is horizontaland level
with, or amaximum of 0.6 metres (2ft) below the topof the
riser rail. Choose a flat piece of wall toavoid the possibility of
distorting the backplate thusmaking thefront cover a poor fit.
3. Adjust the positiontoget the most convenient arrangement taking
the following intoaccount.
•The heater mustnotbe mounted in the directspray from the handset.
•The handset must not be ableto come intocontact withused water inthecubicle, bathor
basin. If it can, evenafter the hose has been retained by the retainingring (see separate
accessories fitting instructionssheet) a vacuumbreaker must be fitted.
4. Fix the riser rail withscrewsprovided (see separate instructions supplied withaccessories).
5. Decide the positionof the electrical cable into the unit. If toporbottomentry is chosen
(according to Diagram 7 onpage 9), cut away the walls inthe backplate as shownin Diagram 2.
6. Decide the positionofentry ofthecold water pipe intotheunit.
If top, cut awa
y the backplate.
If rear, please read the sectiononplumbing.
If bottom, remove thefront cover (complete withknobs) and cut away the detachable corner
sectionas shown.

7. If youhave not yet done so,remove the front cover assembly by undoing the retaining screws at
the top and bottomof the unit and lifting thecover off.
Your shower is provided with2 fixing positions inthe backplate (see Diagram 7 onpage 9).
The top-fixing hole is a “key-hole”slot(another key-hole is provided for alternate fixing),
and should be marked and drilled first.
Tightentop screwwith head protruding about 10mmfromthewall andhook the backplate over
thescrewhead. This allows for correct and accurate alignmentof your shower before marking
and fixing the bottomposition.
Youmay not wishtotightenupbothscrewsat this stage as the holes are elongated to allowfor
adjustment after other connections have takenplace.
b. PLUMBING
WARNING: ENSURE THAT THE MAINS WATERSUPPLY MEETS THE REQUIREMENTS
BELOW BEFORE CONTINUINGWITH INSTALLATION.
The heater must be connected to the mainscold water supply.
This must have a minimum running pressure of 69kPa (0.7 bar, 10 psi)
and a maximumpressure of690kPa (7.0 bar, 100 psi).
WARNING: BEFORE CONNECTINGTHE PIPE WORK TOTHE SHOWER,
ENSURE THATTHE PIPEWORK IS FULLY FLUSHEDOUT.
1. Unscrewthe “Red Cap” fromthe shower outlet pipeand discard it ina suitable manner.
This has beenused toseal the shower during transit, and is nolonger required.
2. It is recommended that a WRAS(Water Regulations Advisory Scheme) listed isolating valve is
fitted tothe incoming mainscold water before theshower unit.
This willallow the unit tobe serviced or exchanged withouthavingtoturnoff thewater at the
water stop valve.
3. Theheater canbe fed from a header tank provided this has a minimum head of7 metres (23ft).
4.
Ø15mmcopper orstainless steel pipe should be used.
Toavoid cross threading, DO NOT REMOVE the nutfromt
he elbow whenpositioning the pipe.
If top entryisrequired, turnthe elbow 180° intothe required position.
If rear entry is required, treat as top entrywithanadditional “Yorkshire” elbow (soldered type)
forfitting intothe rear channel.
Inmultiple installations, correctpipe work sizes should be calculated tomaintainadequate flow
toeach shower.
5. It is permissible touse a WRAS(Water RegulationsAdvisory Scheme) approved sealant sparingly
whilst avoiding excess finding its way intothe shower operating parts.
6. With isolating valve connected, flush thepipe work through to remove any particles etc,
before makingthefinal connectiontothe shower.
Blockage inthe water ways (particularly the handset and solenoid valve) will prevent theheater
working properly. Note: You may be charged for a service call if it isdue toincorrect installation.
7. The shower is designed tohave anopenoutlet andshould onlybe used with “Redring”
recommended fittings.
Donotconnect thehandset until after the shower frontcover and corner section are fitted.

a. Ensure outer knob “A” is aligned fully anti-clockwise to the “ (stop)” position.
b. Ensure inner knob“B” is aligned fully to the “ (medium)” position.
c. Inthe main body ofthe shower, turn the “Drive Spider” fully anti-clockwise until it stops.
d. Inthe main body ofthe shower, turn the “Drive Gite” until it isat “3 o’clock”.
e. Fit the front cover of the shower to the main bodyensuring thatthe 3 x “Drive Spider Legs” engage
with the slots in outer knob “A”.
f. Check that inner knob “A” has been correctly aligned by ensuring thatthe knob can turn approximately
3/4 of a turn (270°).
g. Check that outer knob “B” has been correctly alignedby ensuring thatall 3 power settings canbe
selected, and the knob “B” returns to the “ (stop)” position.
h. Secure by replacing the top and bottom fasteningscrews.
6. Fit theshower hose, andoperate the shower first without the handset to flush out particles,
fit the handset and then operate the shower ason page 7 or 12 andcheck:
a. That the water gets to a satisfactory temperature.
b. Water flow can be adjusted by inner controlknob “B”.
c. Power selection operates in all3 positions, giving a changein water temperatureand thatthe neon
light functions correctly.
d. Checkagain for leaks
e. That the holes in the shower handset are not blocked
7. DEMONSTRATE OPERATION TOUSER
It is recommended that the shower unit and hose etc. be cleaned usinga soft cloth and that theuseof
abrasive or solventbased cleaning fluid be avoided, especially on any platedfinishes.
We recommend that beforeanycleaning, the isolating switch beturned off, thus avoiding accidentally
switching onthe shower.
WARNING: YOUMUST REGULARLYINSPECT THE SHOWERHOSEFORWEARANDDAMAGE.
REPLACEIFNECESSARY, OREVERYTWOYEARS,WITH OUR APPROVEDPART.
WARNING: IN ORDERTO MAINTAIN THE PERFORMANCE OF YOURSHOWER,
YOUMUST CLEAN THE SHOWERHANDSET REGULARLY
Allwater contains particles of lime-
scale, whichbuild up in the shower handset and
unit reducing the performance.
It is therefore important to clean the shower handset bysimplyrubbing the rubber
nozzles, or soaking in a proprietary lime-scale removerand rinsing thoroughly before use.
NOTE: After use it is normal for somewater to drip from theshower handset for a
few moments. This inhibits scale build-up over prolonged use.
7
IFWATER IS TOO COLD
Turn inner knob “B” clockwise in the
direction of the “red arrows” to “1o’clock”
and continue turning clockwise until youget
the water temperature of your liking.
Wait 20 seconds after each adjustment for
the water temperature tostabilise.
If after turning fully clockwise water is still too
cold, set shower pattern on shower handset
to outer or inner pattern only.
IF WATER IS TOO HOT
Turn inner knob “B” anti-clockwise in the
directionof the “blue arrows” to “11 o’clock”
and continue turning anti-clockwise until you
get the water temperature of your liking.
Wait 20 seconds after eachadjustmentfor
the water temperature to stabilise.
If after turning fully anti-clockwise, water is still
too hot, adjust outer knob “A” to “ (medium)”
setting and re-adjust asabove.
Water flow will be reduced on this setting.
1. Ensure the electricity and water are turned on to the unit.
2. Your shower has 3 power settings selected byturning outer
knob “A” (see Diagram 6).
The most popular is “ (high)”.
There are also options for a “ (medium)”
or “ (cold)”shower (see notes 8and 9).
Forthis example turn outer knob “A”to “ (high) ”
and set inner knob “B” to “12 o’clock”.
3. The water will flow and the neonlight will glow brightly.
4. Allowabout 20 seconds for the temperature of the water
to stabilise. Itis recommended that you do not whollyenter the
water spray during this period, especially if the shower has just been used.
5. Once a temperature settingto yourliking has been achieved, inner knob “B” will rarely need
adjusting. You must however take intoaccount required adjustments for variationsof incoming
mains water temperature between summer and winter (see“Effect of Seasonal Incoming Water
Temperature Changes” page 10).
6. When you have finished showering, turn outer knob “A” anti-clockwise tothe “ (stop)” position.
Water will continue to flow for approximately 7 seconds before switching off.
This reduces the temperature of the water inthe tankfor the next user.
Wait forthe water tostop, and then switchoff the electricity at the ceiling switch or local isolator.
7. The “ (medium)” setting of outer knob “A” reduces the power used by the shower giving a cooler
shower or the option of reducedwater flow.
This optionis mainly for summer usage and if this is usedthen inner knob “B” must be re-adjusted.
8. The “ (cold)” setting of outer knob “A” willsupplywater without anyheating,and the neon light
will goout.
9. Your shower is designed to stabilise temperature changes caused by water pressure fluctuations
(see “Effect of Other Water Devices on Incoming Water Supply” page 10).
10. Note that inner knob “B” IS NOTATAP anddoes notturn the water off.
WARNING: DO NOTSWITCH THE SHOWER ON IFYOU SUSPECT IT OFBEING FROZEN.
WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.
WARNING: DO NOTOPERATETHE SHOWER IFWATER ISDISCHARGED FROMTHE
