WARNING: ALL WIRING AND INSTALLATION MUST BE SUPERVISED BY A SUITABLY

QUALIFIED PERSON.

WARNING: DO NOT INSTALL THIS SHOWER WHERE IT MAY BE SUBJECTED TO

FREEZING CONDITIONS

We recommend that the installation is done in the following sequence.
a. Fixing the shower to the wall b. Plumbing c. Electrical connections d. Commissioning

a. FIXING THE SHOWER TO THE WALL

1. Position the riser rail at a convenient height for majority of users as detailed in Diagram 1a/b

and mark its position.

2. Position the heater so that the top of the unit is horizontal and level with, or a maximum of

0.3 metres (1ft) below the top of the riser rail. Choose a flat piece of wall to avoid the
possibility of distorting the backplate thus making the front cover a poor fit.

3. Adjust the position to get the most convenient arrangement taking the following into account.

• 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. If it can, even after the hose has been retained by the soap dish (see Diagram 10), a
vacuum breaker must be fitted (available from us).

4. Fix the riser rail with screws provided. The fixing holes at the base of the brackets will be

revealed by removing the plastic fronts. Assemble as shown in Diagram 10).

5. Decide the position of the electrical cable into the unit.

If top or bottom entry is chosen, cut away the walls in the backplate as shown in Diagram 3.

6. Decide the position of entry of the cold water pipe into the unit.

If top or bottom entry is chosen, carefully cut away the relevant walls of the backplate as shown
in Diagram 2

.

If bottom entry is chosen, refer to note 5 in the plumbing section.

HOW TO INSTALL YOUR CREDA SHOWER

4

7. If you have not yet done so, remove the front cover assembly by undoing the retaining screws at

the top and bottom of the unit and lifting the cover off.
Your shower is provided with 3 fixing positions in the backplate (see Diagram 3).

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 screw with head protruding about 10mm from the wall and hook the backplate over
the screw head. This allows for correct and accurate alignment of your shower before marking
and fixing the bottom position.

You may not wish to tighten up both screws at this stage as the holes are elongated to allow for
adjustment after other connections have taken place.

b. PLUMBING
WARNING: UNDER NO CIRCUMSTANCES SHOULD THIS UNIT BE CONNECTED TO THE

MAINS COLD WATER SUPPLY.

The heater must be connected to a cold water supply gravity fed from a static cold water cistern
with a minimum capacity of 114 litres (25 gallons).
There must be a minimum head of water of 8cm (3”) and a maximum head of 10m (33ft).

This shower is supplied with a filtered isolation valve which MUST BE fitted to the
inlet water supply (see note 2 below and Diagram 9b on page 11).

It is strongly advised to install the shower unit using an independent supply from the cold water
storage cistern. The shower would be totally unaffected by the other draw off points elsewhere in
the system and thus the pressure and temperature will remain more stable.
Therefore, the cold water supply should be taken directly from the cold water cistern.

Under no circumstances should any of the pipework supplying the shower unit rise above the level of
the bottom of the cold water cistern.

Before connecting the pipework to the shower ensure that the pipework is flushed out.

1. Unscrew the “Red Cap” and “Washer” from the shower

outlet pipe and discard them in a suitable manner.
These have been used to seal the shower during transit,
and are no longer required.

2. This shower is supplied with a filtered isolation valve

which MUST BE fitted between the cold water storage
cistern and the shower unit.
This will allow the unit to be serviced or exchanged
without having to turn off the cold water and draining
the cold water cistern.

3. Ø15mm copper pipe should be used. Ensure all burrs

have been removed from the pipes before inserting
into the push fit inlet ports.

Diagram 2 illustrates the correct procedure for inserting
and removing the pipes from the inlet ports.
Take care to line up the inlet pipe correctly with the inlet
port to avoid straining the internal “O”-Ring seal.

DO NOT use solder fittings within 300mm of plastic
fittings.

4. To maintain the optimum performance, the pipe runs

should be kept as short as possible, using sweeping bends
rather than right angles or restrictive fittings.

5

5. If bottom entry has been chosen, the inlet

port must be rotated through 180° into the
required position.
To do this, unscrew the side section from
the shower unit (see Diagram 3).
Rotate inlet connection ensuring that a snug
fit into the cradle is achieved, replace the
side section and tighten screw.

6. With isolating 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 (particularly the
handset and filters) will prevent the shower
unit working properly.

Note: You may be charged for a service
call if it is due to incorrect installation.

7. The shower is designed to have an open

outlet and should only be used with
“Creda” recommended fittings.
Do not connect the handset until after the shower front cover and corner section are fitted.

WARNING: DO NOT FIT A TAP ON THE SHOWER OUTLET.
WARNING: TAKE CARE TO AVOID RESTRICTING THE OUTLET OF THE

PRESSURE RELIEF DEVICE (SEE DIAGRAM 6)

c) ELECTRICAL
WARNING: THIS SHOWER MUST BE EARTHED.

The electrical installation must be in accordance with the current
BS.7671 (IEE Wiring Regulations) and “Part P” of the Building
Regulations and/or local regulations

1. The shower unit is designed for a single phase AC electrical supply.

Please check the rating plate on the unit to see what details apply to your shower.

HOW TO MAINTAIN YOUR CREDA SHOWER

IMPORTANT WARNINGS!

THIS APPLIANCE IS NOT INTENDED FOR USE BY PERSONS (INCLUDING CHILDREN)

WITH REDUCED PHYSICAL, SENSORY OR MENTAL CAPABILITIES,

OR LACK OF EXPERIENCE AND KNOWLEDGE, UNLESS THEY HAVE BEEN GIVEN

SUPERVISION OR INSTRUCTION CONCERNING USE OF THE APPLIANCE

BY A PERSON RESPONSIBLE FOR THEIR SAFETY.

CHILDREN SHOULD BE SUPERVISED TO ENSURE THAT THEY

DO NOT PLAY WITH THE APPLIANCE.

4. A dual position cable clamp is provided.

For top cable entry use retaining bar in horizontal position supplied.
For bottom cable entry rotate retaining bar to the angled position.

d) FINAL INSTALLATION PROCEDURE AND COMMISSIONING
WARNING: DO NOT SWITCH ON THE ELECTRICITY SUPPLY UNTIL THE FOLLOWING

PROCEDURE HAS BEEN COMPLETED. FAILURE TO DO SO COULD CAUSE

THE PUMP TO RUN DRY AND INVALIDATE THE GUARANTEE

1. Fit the front cover back into position, ensuring that both the control knobs are correctly aligned

with the flow valve and power selector. Secure with top and bottom screws.

2. Fit hose and prime the shower first without the handset to flush out any remaining debris. To

prime the shower, ensure that the electricity supply is turned off. Turn control knob “B” fully
anticlockwise. Water should start to flow with motor switched off allowing all the air to be purged
out of the shower unit.

It may be necessary to lower the hose below the level of the shower whilst priming.

Stop water flow by turning control knob “B” fully clockwise. Attach handset, switch on electrical
supply and then operate the shower as on page 7 and check:­a. That the water gets to a satisfactory temperature.
b. Water flow can be adjusted by control knob “B”.
c. Power selection operates in both positions, giving a change in water temperature.
d. Check again for leaks.
e. That the holes in the shower handset are not blocked.
f. That the motor turns off and water stops flowing in the “Stop” position.

3. DEMONSTRATE OPERATION TO USERS

It is recommended that the shower unit and hose etc. be cleaned using a soft cloth and that the use
of abrasive or solvent based cleaning fluid be avoided, especially on any plated finishes.
We recommend that before any cleaning, the isolating switch be turned off, thus avoiding
accidentally switching on the shower.

WARNING: YOU MUST REGULARLY INSPECT THE SHOWER HOSE FOR WEAR AND DAMAGE.
REPLACE IF NECESSARY, OR EVERY TWO YEARS, WITH AN APPROVED PART.

WARNING: IN ORDER TO MAINTAIN THE PERFORMANCE OF YOUR SHOWER,

YOU MUST CLEAN THE SHOWER HANDSET REGULARLY

All water contains particles of lime-scale, which build up in the shower handset and
unit reducing the performance.
It is therefore important to clean the shower handset by simply rubbing the rubber
nozzles, or soaking in proprietary lime-scale remover, rinsing thoroughly before use.

NOTE: After use it is normal for some water to drip from the shower handset for

a few moments. This inhibits scale build-up over prolonged use.

7

IF WATER IS TOO COLD

Turn knob “B” clockwise in the direction

of the “red dots” a small amount and
continue turning clockwise until you get the
water temperature of your liking.

Wait 20 seconds after each adjustment
for the water temperature to stabilise.

The final adjustment may be anywhere on
the scale.

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 knob “B” anti-clockwise in the

direction of the “blue dots” a small amount
and continue turning anti-clockwise until you

get the water temperature of your liking.

The final adjustment may be anywhere on the
scale.

If after turning fully anti-clockwise, water is
still too hot, adjust knob “A” to “ ” low
power setting and re-adjust as above.

Water flow will be reduced on this setting.

1. Ensure the electricity and water are turned on to the unit.

2. Your shower has 2 control knobs (see Diagram 5).

Knob “A” controls the 2 power settings.
The most popular is “high” indicated by “ ”.
There is also a “low” power option “ ” (see note 7).

Knob “B” starts and stops the unit and controls

the temperature of the water.

3. To start the shower turn knob “B” anti-clockwise.

The water will start flowing at around 15° knob rotation
(1 o’clock) and the motor will switch on at around 30°
(12 o’clock). The “power” light will illuminate at this stage.

4. Allow about 20 seconds for the temperature of the water to stabilise.

It is recommended that you test the water temperature with your hand before stepping under
the water spray during this period, even if the shower has just been used.

5. When you have finished showering, turn knob “B” fully clockwise to the “Stop”

position.

The motor will switch off and water will stop flowing.
The “POWER” light will go out.

6. Switch off the electricity at the ceiling switch or local isolator.

7. The “ ” low power setting of knob “A” reduces the power used by the shower giving a

cooler shower or the option of reduced water flow.
This option is mainly for summer usage, and if this is used then knob “B” must be
re-adjusted.

WARNING: DO NOT SWITCH THE SHOWER ON IF YOU SUSPECT IT OF BEING FROZEN.

WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.

WARNING: DO NOT OPERATE THE SHOWER IF WATER IS DISCHARGED FROM THE
PRESSURE RELIEF VALVE.
MAINTENANCE IS REQUIRED BEFORE THE SHOWER CAN BE USED.

WARNING: CONSIDERATION SHOULD BE GIVEN TO SUPERVISING THE YOUNG,
ELDERLY AND THE INFIRM WHILST THEY USE THIS SHOWER.

SELF HELP

If the shower is not working satisfactorily, make the following checks before calling out the installer.
Any one of these adjustments could restore the performance.

The shower cycles

from HOT to COLD

The shower temperature is set too hot causing the thermal cut-out (safety
device) to operate.
Turn knob “B” anti-clockwise (direction of the “blue dots”) to increase water

flow.

Slowly increase the water temperature by turning knob “B” clockwise in the
direction of the “red dots” until a comfortable showering temperature has been
reached.
You MUST WAIT approximately 20 seconds for each adjustment to affect the
water temperature.

CREDA AFTER SALES SERVICE

PROFESSIONAL SERVICE

If the previous “Self Help” checks fail to restore the performance, you should seek professional help.
The person who installed the shower is probably the best one to investigate and correct it and is

certainly the person to contact if you have had a problem in the guarantee period.
The following additional checklist is provided for the benefit of the qualified service person.

WARNING:

SWITCH OFF THE ELECTRICITY AT THE LOCAL ISOLATOR

BEFORE REMOVING THE COVER TO MAKE CHECKS

Water too HOT Water flow restricted by a blockage in either the built-in pump filter or the

isolating valve filter.

Switch off the water supply at the isolation valve and fully isolate the

electricity supply, remove the appropriate filter, clean and replace (see

Diagrams 9a/b).

Water too COLD Check circuit through thermal cut-out.

Check circuit through microswitches on the pressure switch.

Check each element circuit.

Check tightness of electrical connections.

Pump fails to
operate

If the “power” light is illuminated, possible motor failure, replace if necessary.

If the “power” light remains off, check motor switch and replace if necessary.
Pump operates

but no water is
delivered

Faulty motor switch (short circuit). Replace motor switch.

Incorrect alignment of motor switch camdrive.

In off position, the alignment marks on the cam drive (see Diagram 6) should

be centered about motor switch actuator.

Water flow restricted by a blockage in either the built-in pump filter or the

isolating valve filter.

Switch off the water supply at the isolation valve and fully isolate the

electricity supply, remove the appropriate filter, clean and replace (see

Diagrams 9a/b).

1. Water is heated instantaneously as it
flows over the heating elements in
the copper cylinder.

2. Your shower incorporates a pump
which boosts the incoming water
pressure to a level more suitable for
showering.
The motor is controlled by a switch
connected to knob “B”

3. The heaters are only switched on
when

sufficient water is flowing.

This will happen when the motor is
switched on, and is done automatically
with a switch which works on water
pressure.

4. The water is turned on and off by
a tap that is built into the shower.

5. If the water supply falls below a set limit, the pressure
switch will operate and switch off the power to the elements.

6. As a further safeguard, a thermal cut-out switches
the power off if the water temperature climbs above the
set limit and the “overheat” light will illuminate.
This cut-out, which gives an audible click, may also operate
due to residual heat when the shower is switched off.
It will reset itself if water is run through the shower for
10 to 20 seconds, and the “overheat” light will go out.

7. The pressure relief device is to safeguard against
abnormal pressure conditions, and provides a level of
appliance protection should an excessive build of
pressure occur within the shower.

Effect of Seasonal Incoming Water Temperature Changes

The required water temperature is achieved by adjusting the rate of water flow.
Diagram 8 shows the principle involved in relating temperature rise to flow rate.
The higher the water rate the lower the temperature and vice versa.
The temperature of the water supplied from the cold water storage cistern
can vary considerably throughout the year from 5 to 3

0°C.

This means that in the winter, flow rate will be less than in the summer to
ach

ieve the same outlet temperature.

In summer the “ ” low power setting may give adequate hot water.
In some winter conditions, it may be necessary to select the inner or outer spray pattern only of
your shower handset. This will ensure correct operation of the shower with a slightly lower flow rate.
