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.

Diagram 1

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.

Diagram 4

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.

Diagram 7

Diagram 8

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.

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.

Cable Sizes Fuse/ MCB

9.5 / 8.7kW 240 / 230V

10mm² 40 or 45A Cartridge fuse

10.5 / 9.6kW 240 / 230V

Diagram 9

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
