How to use your shower
1. Ensure the electricity and water are turned on to the
unit
2. Functions of buttons: -
Button A – Starts shower on ‘HIGH’ giving maximum
power.
Button B - Starts shower on ‘MEDIUM’ giving
economy setting.
Button C - Starts shower on ‘COLD’ giving water with no heating.
Button D – ‘Shutdown’ switches the shower off and cools the water automatically.
Your shower has 3 power settings selected by pushing the corresponding button on the
front cover. It can be started by pressing A, B or C buttons. Once pressed, a light will
illuminate above the button confirming that power selection has been made.
3. Once either A (HIGH) or B (MEDIUM) have been pressed you will need to adjust the
temperature of the water. This is done by rotating knob “E”. if this is too low then turn the
knob anti clockwise and allow 20 seconds for the temperature to settle. Repeat this
procedure until the temperature is to your liking.
4. If the temperature is too high then turn knob “E” clockwise allowing 20 seconds between
adjustments. The final adjustment can be anywhere on the scale. See diagram 3 for
relationship of flow to temperature.
5. Once a temperature setting to your liking has been achieved knob “E” will rarely need
adjusting, e.g. Adjust for variations of incoming mains water temperature between
summer and winter.
6. When you have finished showering, push button “D” only. The electricity to the
elements is then disconnected and the adjacent light will flash, water will continue to flow
for approximately 5 seconds before switching off. This reduces the temperature of the
water in the unit for the next user. Switch the electricity off at the ceiling switch or local
isolator.
7. Your shower is designed to stabilise temperature changes caused by water pressure
fluctuations. These can result from toilets being flushed or taps being turned on or off.
When this happens your showering temperature will be held within a controlled band,
providing that the minimum pressure required by the shower is maintained.
8. Your shower requires a minimum operating pressure of 100 kPa (1.0 bar, 14.5 p.s.i.). At
pressures above 100 kPa (1.0 bar, 14.5 p.s.i.) it will minimise temperature fluctuations
detailed in note 7. If the water pressure falls below 100 kPa (1.0 bar, 14.5 p.s.i.), it is
likely that the pressure switch will turn off the power to the heating elements, resulting in
a cold shower.

9. During normal operation if the shower senses an overheated water temperature then the
thermal cutout will switch off the heating elements. Water will continue to flow and as the
water temperature falls the heating elements will be turned back on. If the unit continues
to cycle then increase the flow rate by turning knob “E” clockwise and check that the
handset does not require de-scaling. If it still continues to cycle then press button B to the
MEDIUM power setting. (Knob E will need adjusting).
10.Note that knob “E” IS NOT A TAP and does not turn the water off.
WARNING! DO NOT SWITCH THE SHOWER ON IF YOU SUSPECT IT OF BEING
FROZEN. WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.

leaflet. It may also be of use to have a note of the model and serial number as stated on the
underside the shower.
How your shower works
Your shower is designed for
convenience, economy and safety
of use
1. Water is heated
instantaneously as it flows
over the heating elements in
the copper heating tube.
(Diagram 2).
2. The required water
temperature is achieved by
adjusting the rate of water
flow. Diagram 3 shows the
principle involved in relating
temperature rise to flow rate.
The higher the water flow the
lower the temperature rise,
and vice versa. The
temperature of the water
supplied from the mains can
vary considerably throughout
the year from 5 to 20°C. This
means that in Winter, the
flow rate will be less than in
the Summer to achieve the
same outlet temperature. In
summer the ‘MEDIUM’
Diagram 2

power setting may give adequate hot water.
3. The heaters are only switched on when sufficient
water is flowing. This is done automatically with a
switch, which works on water pressure.
4. The water is turned on and off by the solenoid valve
built into the shower. This is switched on by button
A, B or C. (diag. 2)
5. The flow of water is automatically held at the level
set by the user even though the supply pressure
may vary. (See ‘How to use your shower’ note 7).
6. If the water supply falls below a set limit, the pressure switch will operate and switch off
the power to the elements.
7. As a further safeguard, a thermal cutout switches the power off if the water temperature
climbs above a set limit. The cutout gives an audible click when it switches off, but will
reset itself if cold water is run through the shower for 10 to 20 seconds.
8. The pressure relief device is to safeguard against extreme abuse conditions.
9. There are 3 defined spray plate settings adjustable by rotating the spray plate, (see
diagram 4). The modes have a positive “click” to identify them. If desired many
combinations between the 3 can be achieved.
IN ORDER TO MAINTAIN THE PERFORMANCE OF YOUR SHOWER YOU MUST CLEAN
THE SHOWERHEAD.
All water contains particles of lime, which build up in the showerhead and unit reducing
the performance. It is therefore important to clean the showerhead regularly. This is
simply done by rubbing the rubber nozzles. In severe cases you may need to dip the
spray plate into a suitable de-scaling solution.
The frequency of this will vary from weekly to quarterly depending on the water hardness and
experience.
Check the spray plate is then free to rotate to give the three settings.
In some winter conditions, when the incoming mains water is particularly cold it may be
necessary to select the inner or outer spray pattern only. This will ensure correct operation of
the shower with a slightly lower water flow rate
Note: After use it is normal for some water to drip from the showerhead for a few moments, this
inhibits scale build up over prolonged use.

What to do if things go wrong
SELF HELP
If the shower is unsatisfactory, make the following checks before calling out the contractor. Any
of these adjustments could restore the performance
a) Water too HOT
Increase water flow by adjusting the
temperature control clockwise.
Clean spray plate holes. (Select outer or
combination spray patterns).
Switch power to MEDIUM setting.
Increase pressure of water supply e.g. fully
open service valve or stop cock. Check hose is
not kinked restricting the water flow.
b) Water too COLD
Decrease water flow by adjusting the
temperature control anti-clockwise.
Select inner or outer spray patterns only.
Switch power to HIGH setting.
c) Spray pattern poor
Clean spray plate and flush heater with
handset removed. Select inner / outer spray
pattern.
d) 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. another tap
drawing water off. Raise position of handset.
e) Broken parts
Please contact our spares department on
0870 0102 829. Fitting instructions are
provided with spares.
PROFESSIONAL SERVICE
If the previous checks fail to restore the performance, you should either contact the Redring
Technical Advisory Service or seek the assistance of a qualified plumber and / or electrician.
The person who installed the shower is probably the best one to repair it and is certainly
the person to contact if you have a problem in the guarantee period.
The following additional checklist is provided for the benefit of the qualified serviceman.
WARNING – SWITCH OFF THE ELECTRICITY AT THE ISOLATING SWITCH BEFORE
REMOVING THE COVER TO MAKE CHECKS.
a) Water too HOT
Water flow restricted by blockage in filter of
solenoid valve. Switch off water and undo
plastic nut on elbow, loosen brass nut to swing
elbow away from solenoid. Remove filter in
solenoid with long nosed pliers and flush
clean.
b) Water too COLD
Check circuit through thermal cut-out
Check circuit through microswitch on the
pressure switch
Check each element circuit.
Check tightness of electrical connections.
c) Water leaks from burst pressure relief
valve
Check for cause of high pressure and remove
it. Blockage on outlet i.e. blocked spray plate.
Replace the pressure relief disc.
d) Water does not flow when button “A”
“B” or “C is pressed
Check the circuit through the solenoid coil.
Check circuit through microswitch
Possible PCB fault, if defective, then replace.
Power supply not reaching shower.

Installation instructions
Check that the electrical rating shown on the showers matches the mains supply. A
competent installer must undertake all installations. If in any doubt, advice and
assistance should be sought from a qualified plumber and/or electrician. Installations
and wiring must conform to current BS7671 IEE regulations (UK)
WARNING! DO NOT INSTALL THIS SHOWER IN A ROOM
WHERE IT MAY BE SUBJECT TO FREEZING
We recommend that the installation be 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 mark its position.
2. Position the heater so the sides of the unit are vertical
and the top is level with, or up to 0.6 metres (2ft)
maximum below the top of the riser rail. Choose a flat
piece of wall to avoid the possibility of distorting the
back plate thus making the front cover a poor fit.
3. Adjust the positions to get the most convenient
arrangement taking the following into account.
a) The possible need to use the handset over the sink
for hair washing etc.
b) The heater must not be mounted in the direct spray
from the showerhead.
c) The handset must not be able to come into contact
with any used water in the bath or basin. If it can,
even after the hose has been retained by the hose
retainer (see diagram 13), then a vacuum breaker
must be fitted. It should be noted that these devices
are liable to minor leakage so they must be
positioned so that any drips are not detrimental.
4. Fix the riser rail with screws provided. The fixing holes
at the base of the brackets will be disclosed by
removing the plastic fronts. Assemble as shown in
diagram 13.
5. Decide the position of the electrical cable inside the unit. If top or bottom entry is chosen
(according to diagram 6), cut away the walls of the back-plate as shown in diagram 8.
There is also the option to fit the cable from the rear in the channel provided.
6. Decide the cut away position of entry of the cold water pipe into the unit. Cut away the
back-plate and front cover as shown in diagram 7 or 8. There is also the option to have
rear entry (see later section on plumbing).
Diagram 6
Diagram 5

7. If you have not yet done so, remove the front cover
(complete with control knob) of the unit by undoing
the retaining screws at the top and bottom of the
unit and lifting the cover off. The top-fixing hole is a
keyhole slot, and should be marked and drilled
first. Tighten top screw with head protruding about
10mm from wall and hook the back-plate over the
screw head. This allows for correct and accurate
alignment of your shower before marking and fixing
the bottom/side position. You may not wish to
tighten up all 3 screws at this stage as the holes
are elongated to allow for adjustment after other
connections have taken place.
WARNING! TAKE CARE NOT TO DAMAGE THE
PRINTED CIRCUIT BOARD IN ANY WAY. DURING
INSTALLATION AVOID DUST AND DEBRIS
GETTING ON IT.
8. Do not obstruct the pressure relief device found in
the back-plate slot underneath the outlet
connection (see diagram 2). Especially if silicone
sealant or similar materials are used around the
edges of the back-plate.
9. There are a number of clearly marked shields in
the shower unit. These are important for the correct operation of this shower and MUST
NOT be removed under any circumstances.
b) Plumbing (see diagram 9)
The heater should be connected to the mains cold water supply. This must have a minimum
running pressure of 100kPa, 1.0 bar (14.5 p.s.i) and a maximum pressure of 1000kPa, 10
bar (145 p.s.i).
Before connecting the pipe-work to the shower ensure that pipe-work is flushed out.
1. It is recommended that a WRAS (Water Regulations Advisory Scheme) listed isolating
valve is fitted between the rising main and the unit. This will allow the unit to be serviced
without turning off the cold water or exchanged without having to turn off the water at the
water mains stop valve.
2. The heater can be fed from a header tank provided this has a minimum head height of
10.5 metres (35ft).
3. 15mm copper or stainless steel pipe should be used alongside with a standard
compression fitting. In multiple shower installations correct pipe-work sizes should be
calculated to maintain adequate flow to each shower.
4. a) If top entry is chosen, turn the elbow 180°into the required position and fit a standard
15mm in line compression fitting. There is a removable side section, which will aid you
with this (diag.7).
b) If rear entry is chosen, turn the elbow 180°and treat it as top entry except for the fitting
of a ‘Yorkshire’ elbow in the rear channel. The removable side section will again be an
aid.
5. It is in order to use a WRAS (Water Regulations Advisory Scheme) approved sealant
sparingly whilst avoiding excess finding its way into shower operating parts.

6. With the stop valve connected, flush the pipe-work through to remove any particles
etc., before making the final connection to the shower. Blockage in the waterways
(particularly the handset and solenoid valve) will prevent the heater working properly.
7. The shower is designed to have an open outlet and should only be used with ‘Redring’
recommended fittings. Do not connect the showerhead until after the shower front cover
and removable side section are fitted.
WARNING - DO NOT FIT A TAP ON THE SHOWER OUTLET. TAKE CARE TO AVOID
RESTRICTING THE OUTLET AND FLOW FROM THE SHOWERHEAD OR THE
PRESSURE RELIEF DEVICE.
d) Electrical Connections
The electrical installation must be in accordance with the current BS. 7671 (I.E.E.
regulations). If in doubt consult a qualified electrician.
1. The shower is designed for a single-phase A.C. electrical supply. Please check the rating
plate on the unit to see what details apply.
2.
For the 9.5kW you
may be able to use 6mm² cable if Method 1 (clipped direct) is used.
Remember to up rate the cable if it runs in thermal insulation in a loft, or for longer
distance
3. A means for disconnection in all poles must be
incorporated in the fixed wiring in accordance with the
wiring rules. We recommend a ceiling switch mounted in a
convenient position.
4. Cut back cable as in diagram 10. Connect cable to
terminal block making sure that ALL the retaining screws
are VERY tight and that no cable insulation is trapped in
the block.

WARNING - FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN A
FAILURE OF THE TERMINAL BLOCK AND CABLING.
5. WARNING - THIS APPLIANCE MUST BE EARTHED.
6. Ensure that the removable side section is fitted securely into the back-plate.
7. Re- connect cable to front cover PCB (one way fit) see diagram 11.
8. Fit the front cover back into position making sure the knob is
aligned correctly with the flow valve (see diagram 12).
WARNING - TAKE CARE WHEN REPLACING THE FRONT
COVER TO AVOID DAMAGING ANY COMPONENTS.
9. Operate the shower first without the handset to flush out particles, fit
handset and then operate the shower as explained previously and
check:
a) That the water gets to a satisfactory temperature.
b) Power selection does give a change in water temperature.
c) Check again for leaks.
d) That the holes in the spray plate are not blocked.
e) Water flow can be adjusted by knob E
