IN ORDER TO MAINTAIN THE  
PERFORMANCE OF YOUR  
SHOWER YOU MUST CLEAN  
THE SHOWERHEAD.  
NOTE: After use it is normal for some water to  
drip from the shower head for a few moments.  
Check that the HOT water  
isolating valve is open.  
If possible, reposition  
temperature limiting device so  
that more movement of Knob  
'B' is allowed.  
HOW TO MAINTAIN YOUR  
'REDRING' POWER SHOWER  
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 by dipping it in a suitable descaling  
solution. The frequency of this will vary depending  
on site water conditions.  
Turn Temperature Control  
Knob (B) clockwise to a lower  
number on the temperature  
scale. Check that the COLD  
water isolating valve is open.

Cleaning  
WARNING: Switch off the electricity at the  
isolating switch to avoid the shower  
accidentally switching on during cleaning.  
Clean showerhead (see  
opposite).  
e) Poor spray  
pattern  
It is recommended that the shower unit and  
accessories are cleaned using a soft cloth.  
Professional Service  
DO NOT use powerful abrasive or solvent  
cleaning fluids.  
If the above checks fail to restore the  
performance, you should seek professional help.  
WHAT TO DO IF THINGS GO  
WRONG  
Self Help  
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.  
If the performance of the shower does deteriorate  
in service make the following checks before  
calling out the contractor. Any one of these  
simple adjustments could restore the  
performance.  
The following additional checklist is provided for the  
benefit of the qualified serviceman.

WARNING: DO NOT INSTALL THE SHOWER  
IN A ROOM WHERE IT MAY BE SUBJECT TO  
FREEZING.  
We recommend 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  
REDRING AFTER SALES SERVICE  
The Redring Expressions Power Shower is  
fitted with a motor and some mechanical  
noise can be expected when in use. The type  
of wall structure will affect the noise levels.  
Solid walls will provide quieter operation than  
panel or stud partition walls.  
1. Place the riser rail at the height  
recommended in diagrams 5/6 and mark its  
position.  
We offer a technical advisory service on the  
telephone to contractors and other customers  
with problems in the field.

Remember to quote the exact type of shower, as  
written on the front of the shower and on this  
leaflet. It may also be of use to have a note of the  
Catalogue Number as stated on the rating plate  
inside the shower (see diagram 2 for location)  
2. Position the heater so that the sides of the  
unit are vertical and that all controls can be  
comfortably reached whilst the shower is being  
used. Ensure correct orientation of the shower

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 shower unit must not be  
mounted in the direct spray from the  
handset.  
c) The handset must not be able to  
come into contact with the used water in the  
cubicle, bath or basin. If it can, even after the  
hose has been retained by the hose retainer  
(see diagram 12), 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

B) Plumbing  
WARNING : - UNDER NO CIRCUMSTANCES  
SHOULD THIS UNIT BE CONNECTED TO THE  
MAINS COLD WATER SUPPLY.  
The shower unit should be connected to a gravity  
fed water supply from a static cold water cistern  
with a minimum capacity of 114 litres (25 galls).  
There must be a minimum head of water of 8.0cm  
(3'') and a maximum head of 10.0 metres (33ft).  
It is strongly advised that the shower unit is  
installed using independent supplies from the cold  
water storage cistern and hot water cylinder. The  
shower would then be totally unaffected by other  
draw off points elsewhere in the system and thus  
the pressure and temperature will remain more  
stable. The cold water supply should be taken  
directly from the cold water storage cistern and  
the hot water supply should be taken from the hot  
water cylinder via an Essex or Surrey flange (see  
diagram10).  
3. 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 12.  
4. Decide the position of the electrical cable to  
the unit. If top or bottom entry is chosen,  
carefully cut away the relevant walls of the  
backplate as shown in diagram 7.  
5. Decide the position of the water pipes into  
the unit. If top or bottom entry is chosen,  
carefully cut away the relevant walls of the  
backplate as shown in diagram 7. If bottom  
entry is chosen refer to note 8 in the  
plumbing section.  
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.  
6. If you have not yet done so, remove the front  
cover by undoing the retaining screws at the  
top and bottom of the unit. Remove  
Temperature Control Knob 'B' cap (see dia.1)  
by levering out carefully with a small flat  
bladed screwdriver and remove the small  
fixing screw as shown in diagram 14. Your  
shower is provided with four fixing positions in  
the backplate (see diag. 2). The top fixing  
holes are key-hole slots and the most

shows how this flange should be fitted.  
2. Essex Flange (Side entry cylinder flange)  
Fitting Instructions. Alternatively, the hot  
connection to the Shower unit can be taken  
directly from the hot cylinder using an Essex  
cylinder flange and extension pipe.  
Diagram10 explains how the flange should be  
fitted.

Connecting direct to the side of the  
cylinder is not recommended where a  
top entry immersion heater is fitted.  
3. The hot connection can also be taken from  
the hot supply to other outlets as shown in  
diagram 11. The connection must be made  
below the ventilation pipe tee.  
4. In all cases a dedicated cold water supply  
should be taken from the cold water cistern to  
the shower unit. The connection in the cistern  
should be made below the level of the cold  
water feed to the hot water cylinder. The  
connection should also be on the opposite  
side of the cistern to the float valve. This will  
prevent air being sucked into the pump  
chamber.  
5. It is recommended that water council listed  
isolating valves are fitted between the cold  
water storage cistern and the shower unit and  
between the hot water cylinder and the  
shower unit (see diagrams 10/11). This will  
allow the shower unit to be serviced without  
turning off the cold water at the water stop  
valve and draining the cold water cistern.  
6. 15mm copper pipes should be used. Ensure  
all burrs have been removed from the  
pipes before inserting into the push fit  
inlet ports. Diagram 9 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.  
DO NOT insert fingers into the push-fit inlet  
ports. Doing so could result in injury.  
7. Keep pipe runs as short as possible and use  
swept bends rather that right angled or  
restrictive fittings to optimise the performance.  
8. If bottom entry has been chosen, the inlet  
port must be rotated through 1800 into the  
required position. To do this unscrew the  
combined inlet elbow (as shown in diagram 8)  
and remove the side section from the shower  
unit. Remove combined elbow and rotate for  
bottom entry. Slide back into position ensuring  
that the 'O' seals are correctly in place.  
Replace side section and tighten 2 screws in  
elbow to lock into position.

9. With an isolating valve connected, flush the  
pipework through to remove particles etc.  
before making the final connection to the  
shower. A blockage in the waterways  
(particularly the spray rings and filter) will  
prevent the shower unit working properly.  
10. The shower unit should only be used with  
"Redring" recommended fittings.

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 shower hose to the outlet of the  
shower unit. Do not connect the handset at  
this stage. Ensure that the water isolating  
valves are fully open and that the hose is  
directed to waste.  
1. The electrical installation must be in  
accordance with current BS. 7671  
(I.E.E. regulations).  
2. The unit should be connected into a switched  
3 amp double pole fused spur, with a  
minimum contact gap of 3mm in each pole.  
The switch must be fitted outside the  
bathroom.  
Alternatively, a double pole ceiling switch, with  
a pull cord and a minimum contact gap of  
3mm in each pole could be used inside the  
bathroom.  
2. The shower unit is factory set in the  
commissioning mode. A commissioning link is  
connected to the p.c.b. (see diagram 2),  
which opens the solenoid without switching  
on the motor. This allows water to flow  
through the pump, thus ensuring that all air is  
removed.  
The cover is not required to be fitted at this  
stage but be aware of live parts when the  
electricity is temporarily switched on.  
3. Switch on electrical supply. After a few  
moments water should drip from the hose.  
It may be necessary to hang the hose  
from the shower unit whilst priming  
especially if the head of the water is  
minimal. This will speed up the priming  
process.  
For additional safety, it is recommended that a  
residual current device be used with either of  
the above switches.  
3. The earth continuity conductor of the  
electrical installation MUST BE effectively  
connected electrically to all exposed parts of  
the appliances and services in the room in  
which the water heater is to be installed in  
conformity with the current BS. 7671 (I.E.E.  
wiring regulations).  
WARNING : THIS APPLIANCE MUST BE  
EARTHED.  
4. We recommend using 1.0mm2 Twin and Earth  
cable for this application. Connect the mains  
cable in to the terminal block, ensuring that all  
power is switched off before connecting to the  
mains supply.  
Recommended order : -  
a) Strip back wire approximately 6.0mm.  
b) Ensure wires are secure in the correct  
terminal block holes.  
When water drips through the hose at a  
constant rate. Stop flow of water by switching  
off the electrical supply.  
c) Ensure that the mains cable is securely  
clamped in the cable clamp provided  
on the backplate.  
Ensure electricity is switched off. Remove  
p.c.b. commissioning link. Replace with the  
connector attached to the front cover  
start/stop/flow control switch.

FILTER REMOVAL AND REFITTING.  
Inlet filters have been incorporated in the design  
of the Expression power shower which protect  
the internal mechanisms of the shower unit and  
the handset. If the performance of the shower  
deteriorates (ie. Flow reduction occurs) then it  
may be necessary to clean the filters.  
WARNING : ISOLATE FROM MAINS  
ELECTRICITY AND WATER SUPPLY BEFORE  
REMOVING THE COVER TO MAKE CHECKS.  
Remove shower cover as described in note 6 on  
page 6. The cover will be connected to the PCB  
via a flying lead. Carefully pull the lead from the  
PCB.  
DO NOT let the front cover hang by the lead  
as this will damage the PCB.  
correctly and pressing firmly home.  
6. Switch on electrical supply and  
then operate the shower as shown on page 2  
and check : -  
a) The shower switches on when the flow  
control knob 'A' is rotated and that flow is  
adjustable.  
b) Temperature can be adjusted by knob 'B'  
and the limiter position is satisfactory (ie. Not  
hot enough to scald).  
c) Operation of override button allows the  
temperature limiter position to be overridden.  
d) Check again for leaks.  
e) That the motor turns off and water stops  
flowing in the STOP position of knob 'A'  
7. PLEASE DEMONSTRATE  
OPERATION TO THE USER.  
Please leave these instructions with the user for  
future reference.  
The filters are positioned in the inlet housing as  
shown in diagram 13 below. Remove 2 fixing  
screws and the filter cap from the housing and  
remove both filters. Wash thoroughly under  
running water and replace in housing. Ensure that  
both 'O' seals are fitted to the filter cap and re-  
assemble cap using 2 fixing screws.  
It may be necessary to re-prime the shower unit  
after the filters have been cleaned. Please refer to  
the commissioning procedure (page 9).
