Plumbing
1. The Mira Vista 8.5 kW and 9.5 kW electric shower is designed to operate with
a minimum maintained inlet pressure of 70 kPa (0.7 bar) up to a maximum
static inlet pressure of 1000 kPa (10 bar).
2. The appliance is normally connected to the cold water mains-fed supply.
However, the water supply can be taken from a cold water storage cistern,
provided there is a minimum maintained inlet head of water of 7 metres (the
vertical distance from the base of the cold water storage cistern to the shower
tting handset). To reduce pressure losses and uctuations, the cistern-fed water
supply must be independent from other supply draw-offs, and should avoid long
horizontal pipe runs and use swept bends rather than 90° elbows. For further
advice please refer to the back cover of this guide for Mira Showers contact
telephone and fax numbers.
3. The appliance is suitable for installation within the shower area. It is tted with
a pressure relief device and must be positioned over a water catchment area
with the controls at a convenient height for the user. The shower tting should
be positioned so that it discharges down the centre line of the bath, or across
the opening of a shower cubicle, and must be directed away from the appliance.
4. The appliance is tted with an inlet connector assembly that is designed to accept
plumbing supplies from the top or bottom. The water supply can be fed with
15 mm pipe or 10 mm microbore pipe, suitably adapted into the inlet connector
assembly. If 10 mm microbore is used, then an allowance for increased pressure
loss must be made to ensure that the minimum maintained inlet pressure is
achieved.
5. Do not t the appliance to the wall and tile up to the case. The appliance must
be tted onto a nished at and even wall surface. Otherwise, difculty may
be encountered when tting the cover, and subsequent operation of the unit
could be impaired (small pillars moulded on to the back of the case allow air
circulation).
6. Use only the inlet connector assembly supplied with the appliance. Do not use
any other types of tting.
7. Refrain from applying excessive force when making any connections. Always
provide mechanical support when making the plumbing connections.
8. This appliance is not designed to be plumbed directly from the rear. For a rear-
entry supply, add an elbow to the supply pipe and connect it as a rising or falling
supply.
9. Do not install the appliance in a position where it may become frozen. The
shower unit must not be tted where it may be exposed to freezing conditions.
The shower unit must not be used if you suspect it may be frozen.
INSTALLATION REQUIREMENTS

10
Spillover
Level
Hose Retaining
Ring
10. We recommend that a non-restrictive (free-owing) isolating valve is tted in the
cold water supply pipe to allow the complete maintenance of the appliance. Do
not use a valve with a loose washer plate (jumper) as this can lead to a build
up of static pressure.
11. To avoid damage to the case when soldered ttings are used, pre-solder the
pipework and ttings before connecting them to the inlet stub.
12. Supply pipework MUST be ushed to clear debris before connecting the
appliance.
13. The appliance is tted with a 1/2” BSP male outlet thread, to accept a Mira Vista
shower hose.
14. When installed in very hard water areas (above 200 ppm temporary hardness)
your installer may advise the installation of a water treatment device, to reduce
the effects of limescale formation. Appliance malfunction due to excessive
limescale formation is not covered by the manufacturer’s guarantee. Your local
water company will be able to advise on the hardness of water in your area.
15. A hose retaining ring is supplied to
prevent the handset from dropping
below the spillover level of the bath
or shower, which could lead to
contamination from back-siphonage.
The supplied hose retaining ring
should meet the majority of user
requirements for shower installations
with exible outlet ttings. However,
there will be occasions when the
hose retaining ring will not provide a
suitable solution. In these instances
an outlet double checkvalve must be
tted. This will increase the required
supply pressure typically by 10 kPa
(0.1 bar).
Double checkvalves, fitted in the
inlet supply to the appliance, cause
a pressure build-up, which could
exceed the maximum static inlet
pressure for the appliance.
16. Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
25 mm minimum

11
Electrical
1. In a domestic installation, the rating of the electricity supply company fuse and
the consumer unit must be adequate for the additional demand. This is a high-
power appliance, and it is essential to contact your electricity supply company
to ensure that the supply is adequate for the appliance. Voltage drop due to
local heavy demand will reduce the performance of the shower.
2. The appliance must be earthed by connecting the supply-cable earth conductor
to the earth terminal.
Supplementary bonding: Within the bathroom or shower room, all accessible
conductive parts of electrical equipment and extraneous conductive parts that
are likely to introduce earth potential, must be electrically bonded to earth using
a minimum cable size of 4.0 mm2 if the cable is not mechanically protected
(2.5 mm2 if mechanically protected).
3. The minimum cable size (cross-sectional area) must conform to BS 7671.
4. To obtain full advantage of the power provided by this unit, use the shortest
possible cable route from the consumer unit to the shower.
5. A 30 mA residual current device (RCD) must be tted. This may be part of the
consumer unit or a separate unit.
Plumbing and Electrical Schematic
6. A separate, permanently connected
supply must be taken from the
consumer unit to the appliance
through a double-pole switch,
which has a minimum 3 mm contact
separation. The switch can be a
ceiling mounted pull-cord type within
the shower room, or a wall mounted
switch in an adjacent room.
7. DO NOT twist the individual cable
cores of the live and neutral
conductors, as this will prevent them
from entering the terminal block.
8. DO NOT exert strain on the terminal
block.
9. DO NOT turn-on the electrical
supply until the plumbing has been
completed.

Warning! Isolate the electrical and water supplies before installing the shower.
1. Remove the three screws that hold the cover on the shower and remove the
cover.
2. Decide on a suitable position for the appliance (minimum distance of 200 mm
from the ceiling to allow for cover t and removal). The position of the appliance
and the shower ttings must provide a minimum gap of 25 mm between the
spill-over level of the shower tray/bath and the handset. This is to prevent
backsiphonage
3. Place the shower in the required position on the wall and mark the positions
of the three xing holes in the shower case. Ensure that there are sufcient
lengths of supply pipe and electrical cable to reach the connection points.
4. Remove the shower and drill three
holes to suit appropriate xing screws
and wall plugs.
Caution! Do not drill into cables or
pipes in the wall.
5. Thoroughly ush the supply pipe.
6. On the shower, turn both knobs to
the full anti-clockwise position.
7. Remove the service tunnel from the
shower.
8. Determine the direction of the

(entering the shower from the top),
or rising (entering the shower from
the bottom).
Do not use an incoming supply
entering the shower directly from
the back. Add an elbow to the supply
pipe and connect it as a rising or
falling supply.
9. Rotate the inlet connector to suit
the direction of the incoming water
supply.

10. The case has thinned sections that
can be removed to allow entry of the
supply pipe and electrical cables.
Remove the top thinned section
of the case for a falling supply, or
remove the bottom thinned section of
the service tunnel for a rising supply.
11. Do not remove any case sections if
the electrical cables enter from the
back.
12. Secure the shower to the wall.
13. Connect the inlet supply pipe to
the inlet connector using a 1/2”

If you are unsure how electric showers work, please read through the Operation
section before continuing.
1. Make sure that the TOP control knob is in the ‘STOP’ position and that the
electrical supply has been isolated.
2. Turn the BOTTOM control knob fully anticlockwise to the full cold position.
3. Turn the water supply fully on at the isolating valve, check that water is not
leaking from the bottom of the case.
4. Switch on the electrical supply at the double pole switch.
5. Turn the TOP control knob to the ‘LOW’ position. Check that water ows freely
from the shower within a few seconds. If not, refer to the Maintenance section.
The water from the handset will be at full force and at a cool temperature.
6. Turn the BOTTOM knob slowly clockwise. As the knob is rotated the ow will
be reduced and the temperature will remain cool - this shows that the ow
regulator assembly is operating correctly. Return the knob anticlockwise to full
cold position.
7. Turn the TOP knob to the ‘ECO’ position. The temperature of the water should
rise slightly. Allow a few seconds for the warm water to reach the handset - this
shows that the ‘ECO’ power setting is operating correctly.
8. Turn the TOP knob to the ‘HIGH’ position. The temperature of the water will
rise further - this shows that the full power setting is operating correctly.
9. Set the shower temperature by rotating the BOTTOM knob as necessary. Turn
the knob clockwise for hotter water and anticlockwise for cooler water.
Note! When the temperature is changed the ow rate will change.
10. When the required temperature is reached, turn to the STOP position to stop the
ow. Water may continue to ow from the handset for a few moments during
shut-down, as water is purged from the tank. Isolate the power at the double
pole switch.
11. A small amount of water may be retained in the shower tting after the shower
control has been turned off. This may drain over a few minutes.
Note! A slight hissing sound may be heard from the appliance during operation.
High mains water pressure and high shower temperatures will effect the tone.
This is quite normal when the shower is in use.
COMMISSIONING

16
Advice to Users
Note! Read the Important Safety Information section rst.
Warning! The spray plate holes must be kept clear. Lack of regular spray plate
cleaning will lead to poor performance and cause early failure of the appliance. See
the shower ttings User Guide for more information.
1. Electric showers work by taking in cold water and passing it over the heating
elements contained in the tank inside the shower.
2. The showering temperature is adjusted by turning the temperature control knob,
which varies the ow of cold water across the elements. The slower the rate of
ow, the warmer the water, and vice versa. The holes in the spray plate of the
shower handset should always be kept clean to maintain a consistent ow and
stable shower temperatures.
3. The appliance is designed to stabilise temperature changes caused by water
pressure uctuations. These uctuations can be caused by taps being turned
on or off, or toilets being ushed. Under such conditions, average shower
temperatures will be held within a 6°C range, provided that the minimum required
pressure is maintained.
4. Seasonal changes in the temperature of the incoming cold water supply and/or
uctuations in mains electrical voltage will effect the temperature of the water.
Adjust the temperature knob as necessary to compensate.
5. The shower requires a minimum maintained/running pressure of 70 kPa (0.7 bar)
to operate. At pressures above 70 kPa (0.7 bar), the shower will minimise the
temperature uctuations caused when other draw-off points are used. If the ow
rate drops below an acceptable level, the heating element inside the shower
will turn off, resulting in a cold shower.
6. If the water temperature reaches an unsafe level, the thermal switch assembly
turns off the heating elements. As the water temperature falls the elements will
be turned on. The switch will cycle on/off/on if the ow rate is not increased and
the temperature of the shower reduced.
7. Check the shower temperature before entering the shower. The previous user
may have selected a different temperature setting.
8. When the shower is rst turned on, or the temperature setting is changed, there
will be a slight delay before the water temperature changes.
OPERATION

17
Operation Instructions
To turn the shower on
1. Switch on the electrical supply at the
double pole switch.
2. Turn the power knob to High. Wait
15-20 seconds for warm water to
reach the handset.
For electrical economy, set the power
knob to ECO. This setting will provide
sufficient power when the supply
water temperature is warmer, such
as in the summer.
For an unheated shower, set the
power knob to Low.
To set the shower temperature
1. Set the shower temperature by
rotating the temperature knob as
necessary. Turn the knob clockwise
for hotter water and anticlockwise for
cooler water. Wait 10–15 seconds for
the adjusted temperature to reach the
handset.
Note! It is normal for the ow rate
to change when the temperature is
changed.
Note! If the water temperature
cycles between hot and cold, the
temperature is set too high. This is
causing the thermal switch to turn
off the heating element to reduce
the water temperature. Turn the
temperature knob anticlockwise to
reduce the water temperature.
To turn the shower off
1. Turn the power knob to Stop.
Note! A small amount of water may
continue to ow from the handset for
a few moments.
2. Switch off the electrical supply at the
