•Your shower has been designed for
convenience, economy and safety of use,
provided that it is installed, used and
maintained in good working order and in
accordance with our instructions and
recommendations.
•All wiring and installation must be
supervised by a suitably qualified person
•THIS APPLIANCE MUST BE EARTHED.
•The installation must be in accordance with
the current edition of BS.7671 (
the ‘IEE Wiring
Regulations’) and ‘Part P’ of the ‘ Building
Regulations’
in force at the time of installation.
Installations outside England and Wales must
also conform to any local regulations in effect
•This appliance is intended to be permanently
connected to the fixed electrical wiring of the
mains supply with its own dedicated supply.
•This appliance must NOT be fitted where it
may be subjected to freezing conditions
•DO NOT switch the appliance on if you
suspect it of being frozen.
Wait until you are sure it has thawed out.
•DO NOT fit any sort of tap or control on the
appliance outlet.
The appliance is designed to have an open
outlet and should only be used with
Manufacturer’s recommended fittings.
•THIS SHOWER IS DESIGNED AND
APPROVED TO EN-60335 WITH THE
HANDSET PROVIDED.
UNDER NO CIRCUMSTANCES MUST ANY
HANDSET THAT IS NOT APPROVED BY THE
MANUFACTURER BE USED WITH THIS
PRODUCT.
•Take care to avoid restricting the outlet of the
pressure relief device (fig.15).
If water is discharged from the pressure relief
device, maintenance will be required before
the appliance can be safely used.
•Isolate the mains electrical and water supply
before removing the appliance front cover.
•This appliance is not suitable for mounting
into steam rooms or steam cubicles.
•We DO NOT recommend this appliance be
used in heavy or unsupervised commercial
applications.
The following points will help you have a greater
understanding of how your shower works:
•The electric heating elements operate at a
constant rate, dependant on your chosen
power setting.
The required water temperature is achieved
by adjusting the rate of water flow.
The higher the water flow the lower the
temperature 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 the winter, flow rate will be
less than in the summer to achieve the same
outlet temperature.
In summer the ‘Economy’ (2 red bars) power
setting may give adequate hot water.
•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 and off.
When this happens your showering
temperature will be held within a controlled
band, provided that the minimum pressure
required by the shower is maintained (page.4)
If the water pressure falls below the minimum
pressure required, it is likely that the pressure
switch will turn off the power to the heating
elements, resulting in a cold shower.
•DO NOT place items such as soap, shampoo
or other such bottles on top of the unit.
Liquid could leak through the joint between
the cover and backplate, and possibly damage
the sealing rubber.
11
Effect of Seasonal Incoming Water
Temperature Changes
The required water temperature is achieved by
adjusting the rate of water flow.
The diagram 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
mains can vary
considerably throughout
the year from 5 to 20°C.
This means that in the winter, flow rate will be
less than in the summer to achieve the same
outlet temperature.
In summer the ‘Economy’ (2 x red bars) power
setting may give adequate hot water.
Effect of Other Water Devices on Incoming
Water Supply
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 and off.
When this happens your showering temperature
will be held within a controlled band, provided
that the minimum pressure required by the
shower is maintained.
Your shower requires a minimum running
pressure of 100kPa (1.0 bar, 15 psi) at a
minimum flow rate of 8 litres/minute.
(
9 litres/minute for 9.5kW).
At pressures above 100kPa (1.0 bar, 15 psi) at a
minimum flow rate of 8 litres/minute.
(
9 litres/minute for 9.5kW), it will minimise
temperature fluctuations as detailed above.
If the water pressure falls below 100kPa
(1.0 bar, 15 psi) at a minimum flow rate of
8 litres/minute, (
9 litres/minute for 9.5kW),
it is likely that the pressure switch will turn off
the power to the heating elements, resulting in a
cold shower.
Please Note:-
The fitting of Spare Parts must be supervised
by a suitably qualified person.

1. Water is heated instantaneously as it flows
over the heating elements in the heat
exchanger (fig.15).
2. The heaters are only switched on when
sufficient water is flowing.
This is done automatically with a switch
which works on water pressure and is
indicated by the ‘Power’ light illuminating.
3. The water is turned on and off by the
solenoid valve built into the shower.
This is switched on when Knob ‘A’ is rotated.
4. The flow of water is automatically held at the
level set by the user even though the supply
pressure may vary (see ‘Advice to Users’).
5. If the water supply falls below a set limit, the
pressure switch will operate and switch off
the power to the elements, resulting in a cold
shower (see ‘Advice to Users’ on page.2).
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.

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
a. FIXING THE SHOWER TO THE WALL
1. Position the riser rail at a convenient height
for majority of users (fig.1) and mark its
position (see fig.10 for accessory details).
2. Position the heater so that the top of the
unit is horizontal and level with, or a
maximum of 0.6 metres (2ft) 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 (fig. 10),
a vacuum breaker must be fitted.
4. Fix the riser rail with screws provided.
5. Remove the front cover by undoing the
retaining screws at the top and bottom of
the unit and lifting the cover off.
6. Remove the detachable corner section by
undoing the 4 x fixing screws (fig.2).
7. Decide the position of the electrical cable
and cold water pipe into the unit.
If bottom entry is chosen, cut away the walls
in the detachable corner section and
backplate if applicable (fig.3 & 4a/b).

4
8. If top entry is chosen, remove the cable/pipe
entry, and cut away (fig.5).
9. If rear, please read the section on plumbing.
10. Your shower is provided with 2 wall-fixing
positions in the backplate.
The top-fixing hole is a ‘key-hole’ slot, 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:
ENSURE THAT THE MAINS WATER SUPPLY
MEETS THE REQUIREMENTS BELOW
BEFORE CONTINUING INSTALLATION.
The heater must be connected to the mains cold
water supply.
This must have a minimum running pressure of
100kPa (1.0 bar, 15 psi) at a minimum flow rate
of 8 litres/minute*.
The maximum static pressure must be no greater
than 1000kPa (10 bar, 150 psi).
*
Minimum running pressure must be obtained
at 9 litres/minute for 9.5kW.
WARNING:
BEFORE CONNECTING THE PIPE WORK TO
THE SHOWER, ENSURE THAT THE PIPE
WORK IS FULLY FLUSHED OUT.
1. It is recommended that a WRAS (Water
Regulations Advisory Scheme) listed isolating
valve is fitted to the incoming mains cold
water before the shower unit.
This will allow the unit to be serviced or
exchanged without having to turn off the
water at the water stop valve.
2. The water inlet connection is a plain Ø15mm
straight shank/shaft.
This will accept either a Ø15mm compression
elbow or a Ø15mm ‘push-on elbow’.
If rear entry is required, treat as top entry
with an additional ‘Yorkshire’ elbow (soldered
type) for fitting into the rear channel.
Ø15mm copper or stainless steel pipe should
be used.
In multiple installations, correct pipe work
sizes should be calculated to maintain
adequate flow to each shower.

Remember to quote the exact type of shower,
as written on the front of the shower and on this
leaflet.
The model and serial number are located on the
bottom face of the shower.
Make a note of those numbers here, and be sure
to quote them if you call for advice.
Model Number: 53-56_ _ _ _ _ _ _ _ _ _ _
Serial Number: _ _ _ _ _ _ _ _ _ _ _ _ _ _
NOTE:
You may be charged for a service call
if you do not have the serial number.
It is recommended that the shower unit and
accessories 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 OUR 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 rubbin
g
the rubber
nozzles, or soaking in a proprietary lime-scale
remover and 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 lime-scale build-up over prolonged
use.
5
3. It is permissible to use a WRAS (Water
Regulations Advisory Scheme) approved
sealant sparingly, avoiding excess finding its
way into the shower operating parts.
4. With the 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 solenoid valve) will prevent the
heater working properly.
Note: You may be charged for a service call
if it is due to incorrect installation
.
5. The shower is designed to have an open
outlet and should only be used with the
manufacturers recommended fittings.
Do not connect the handset until after the
shower front cover and detachable 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.
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.
AS A GUIDE ONLY (* Only applies if external earth
impedance is less than 0.35 Ohms)
Remember to upgrade the cable if it runs in
thermal insulation in a loft, or for longer distances.
2. 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.
3. Cut back cable (fig.6).
Connect cable to terminal block making sure
that all the retaining screws are VERY
TIGHT and that no cable insulation is
trapped under the screws.
WARNING:
FAILURE TO COMPLY WITH THESE
INSTRUCTIONS COULD RESULT IN

Ensure you connect the flying-lead from the
unit to the plug on the PCB on the inside of
the front cover (fig.7).
This will ensure that lights will illuminate.
Ensure Knob ‘A’ is aligned to the ‘Stop’
position, whilst the ‘D-Shaft’ in the product is
aligned as shown (fig.8).
Ensure Knob ‘B’ is aligned at 6 o’clock,
whilst the ‘spindle’ in the product is rotated
fully clockwise as shown (fig.9).
Ensure that Knob ‘A’ has been correctly
aligned by ensuring that all 3 power settings
can be selected.
Ensure that Knob ‘B’ has been correctly
aligned by turning from minimum to
maximum flow (approximately 1 full turn)
mid position should be at 12 o’clock.
6. If you have not yet done so, assemble the
accessories (fig.10).
7. Fit the shower hose, and operate the shower
first without the handset to flush out
particles, fit the handset and then operate
the shower as on page 7, then please check:
•That the water gets to a satisfactory
temperature and water flow can be
adjusted by Knob ‘B’.
•Knob ‘A’ power selection operates in all
3 positions, giving a change in water
temperature and that the power indictor
light functions correctly (if light does not
work, check flying-lead from the unit has
been connected to the PCB on the inside
of the front cover fig.7).
•Check again for leaks.
•That the holes in the shower handset are
not blocked.
8. DEMONSTRATE OPERATION TO USERS,
AND LEAVE THIS BOOKLET WITH THEM
FOR FUTURE REFERENCE.
7
Ensure the electricity and water are turned on to
the unit.
Your shower has 2 control knobs (fig.13).
Knob ‘A’ controls the power selection.
‘High’ - (3 red bars)
‘Economy’ - (2 red bars)
‘Cold’ - (1 blue bar)
Knob ‘B’ controls the temperature of the water.
TO START THE SHOWER
Turn Knob ‘A’ to your
desired power setting
(normally ‘High’).
Water will start to flow,
and the ‘Power’ light
will illuminate (fig.11).
It is recommended that you do not wholly enter
the water spray during this period, especially if
the shower has just been used.
If the water is not at your desired showering
temperature, turn Knob ‘B’ a small amount
until the desired temperature is achieved.
Turn anti-clockwise for cooler (fig.12a).
Turn clockwise for warmer (fig.12b).
Allow about 20 seconds for the temperature
of the water to stabilise.
Final adjustment may be anywhere on the scale.
If after turning fully anti-clockwise, water is still
too hot, adjust Knob ‘A’ to ‘Economy’ setting
and re-adjust as previously detailed.
Water flow will be reduced on this setting.
TO STOP THE SHOWER
Turn ‘Knob A’ to the
‘Stop’ position (fig.14)
Water will cease to flow
and the ‘Power’ light
will go out.
Switch off the electricity
at the ceiling switch
or local isolator.
Once a temperature setting to your liking has
been achieved, Knob ‘B’ will rarely need
adjusting. You must however take into account
required adjustments for variations of incoming
mains water temperature between summer and
winter (see ‘Advice to users’ on page.2).
The ‘Economy’ 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.
The ‘Cold’ setting of Knob ‘A’ will supply water
without any heating.
During normal operation, if an overheated water
temperature is sensed then the heater will switch
off and the ‘Overheat’ light will illuminate.
Water will continue to flow and cool down before
the heater switches back on again.
Note: the ‘Overheat’ light may come on at the
start of a showering session if the shower has
recently been used.
It will automatically reset itself when water has
been run through the shower for a few
moments.
