1 PLUMBING NOTES
1.1 All installations must comply with Water
Regulations or Water Bylaws.
1.2 Supply pipes must be flushed to clear
debris before connecting the shower unit.
1.3 DO NOT connect the shower unit to
the mains cold water supply as it would
damage the unit and also, the installation
would be in breach of Water Regulations.
1.4 DO NOT use excessive force when making
connections to the flexible hose or
showerhead – finger tight is sufficient.
1.5 ALL plumbing connections are to be
completed and water supplies turned on
BEFORE switching on the electricity supply.
The shower must not be operated dry
without water.
1.6 DO NOT solder pipes or fittings within
300 mm of the shower appliance, as heat
transfer can damage components.
1.7 When installed, the top of the shower unit
must be at least 75 mm lower than the
base of the cold water storage cistern to
prevent the pump being run dry without
water.
1.8 A dedicated cold water supply must be
taken directly from the cold water cistern
to the shower. This draw-off must be on
the opposite side of the cistern to the float
operated valve to reduce the risk of air
entering the unit.
1.9 The action of the pump is to increase the
flow rate. If the supply pipework cannot
handle the resulting flow rate then:
1.9.1 The anticipated flow rate may not
be achieved.
1.9.2 Air may be drawn into the hot
supply from the vent pipe causing
spluttering and temperature fluctuations at
the showerhead.
1.10 Fullway isolating valves MUST be fitted
on the hot and cold water supplies to
the shower as an independent means
of isolating the water supplies should
maintenance or servicing be necessary. DO
NOT use stop taps or ball-o-fix type valves
which restrict flow.
2 ELECTRICAL NOTES
2.1 The installation must comply with BS 7671
‘Requirements for electrical installations’
(IEE wiring regulations). Make sure the
incoming hot and cold water supplies to
the shower are adequately earth bonded.
2.2 DO NOT turn on the electrical supply
until the plumbing connections have been
completed. Only then can the electricity be
switched on in order to power the solenoid
to turn water on to the shower when
commissioning. The shower must not be
operated dry without water.
2.3 The mains supply must be 230/240V, at
50Hz, connected to the unit via a double
pole switched 3 Amp fused connection
unit (not supplied) with a minimum 3 mm
contact separation gap in each pole.
2.4 In accordance with ‘The Plugs and Sockets
etc. (Safety) Regulations 1994’, this unit
is intended to be permanently connected
to the fixed electrical wiring of the mains
system.
2.5 Fuses do not give personal protection
against electric shock.
2.6 A 30mA residual current device (RCD)
MUST be installed. This may be part of the
consumer unit or a separate unit.

SPECIFICATIONS
Hot water temperature
Maximum temperature 65°C.
BS 6700 recommends that the temperature of
stored water should never exceed 65°C. A stored
water temperature of 60°C is considered sufficient
to meet all normal requirements and will
minimise the affects of scale in hard water areas.
Temperature control
To obtain the maximum performance, this unit
should be installed, operated and maintained
as instructed in this book. The full performance
specification as below for the standard unit is
achieved with a blend set between 35°C – 40°C
and supplies of 15°C cold and 65°C hot with
nominally equal pressures.
1) The blended water temperature is
maintained within 2°C with a 10°C change
in the hot and cold water supply.
2) The sensor effects a shut down to seepage in
approximately 2 seconds if the cold supply fails.
3) Shut down to seepage is achieved even if
the hot supply is only 12°C above the blend
temperature.
4) The blended water temperature is
maintained within 1°C when the pressure
between inlet and outlet is halved (defined
as a pressure loss ratio of 2:1) on either the
hot or cold side.
Maximum static inlet pressures
100 Kpa (1 bar) or 10m (supplies must be
gravity fed at nominally equal pressures).
Minimum static inlet pressure
0.75 Kpa (0.0075 bar) or 75mm (required to
prime the integral centrifugal pump).
Maximum supply head 10m.

SITE REQUIREMENTS
Water
The installation must be in accordance with
Water Regulations.
For correct operation of this shower unit, both
hot and cold water supplies to the appliance
must be gravity fed, at nominally equal
pressures, from a cold water storage cistern and
a hot water storage cylinder.
The water circuit should be installed so that the
flow is not significantly affected by other taps
and appliances being operated elsewhere on the
premises.
Fig.2 shows a recommended installation where
the hot water supply for the shower is made via
a tee connection on the underside of the rising
horizontal section of pipework from the cylinder.
Alternatively, the connection can be taken from
the hot supply pipe to other outlets as long as it
is the first draw-off below the ventilation pipe tee.
Fig.3 illustrates all the incorrect connections that
must be avoided.
All pipework to the shower unit must be routed
where it remains below the level of water in
the cistern. In the case of horizontal sections
of pipework in lofts, it may be necessary to
fit automatic air vents at high points on the
supplies to remove the possibility of air locks.
For the operation of the shower only, it is
recommended that the cold water storage
cistern is capable of holding at least 114 litres
(25 gallons). Where other hot and cold outlets
are likely to be in use simultaneously, the storage
capacity should be increased to 228 litres (50
gallons) in accordance with BS 6700.
Do check compliance with all the local Water
Regulations/Bylaws.
DO NOT connect to a combination cylinder
unless there is a guaranteed 114 litre cold supply
to the cylinder as the shower can deliver up to
14 litres per minute. It is advisable to check that
Fig.2 (Diagrammatic view – not to scale)

Aspirante thermostatic power shower
5
the infill rate from the float operated valve meets
the output requirements.
It is recommended that there is a minimum
of approximately 114 litres (25 gallons) of hot
water storage per appliance.
The shower MUST NOT be connected to the
mains cold water supply.
DO NOT use jointing compounds.
GENERAL INSTALLATION NOTES
1. DO NOT take risks with plumbing or
electrical equipment.
2. DO NOT install this unit in a position where
it could become frozen.
3. Isolate electrical and water supplies BEFORE
proceeding with installation work.
4. Shower control MUST be fed from a cold
water storage cistern and hot water cylinder
that provides nominally equal pressures.

5. The unit must be mounted onto the finished
wall surface (on top of tiles). DO NOT tile up
to the unit after fixing to the wall.
6. If installing with rear inlet supplies, it is
recommended the supply pipework is sealed
to the wall to prevent water from leaking
back into the wall.
7. In solid wall installations, the supply pipework
should be housed within ducting in order
to allow some free lateral movement when
making connections and to make sure of
compliance with the requirements of Water
Regulations (accessibility of pipes and pipe
fittings).

OF TILED WALLS. NEVER TILE UP TO THE
APPLIANCE.
Refer to fig.5 for correct siting of the shower.
Position the appliance vertically where it will
NOT be in direct contact with water from the
showerhead.
Note: Allow enough room between the ceiling
and the shower unit to access the top cover
screw.
Position the shower and showerhead on the wall
so that all controls can be comfortably reached
while using the shower.
The showerhead and riser rail can be positioned
either side of the shower unit.
Note: Water Regulations require the
showerhead be ‘constrained by a fixed or sliding
attachment so that it can only discharge water at
a point not less than 25 mm above the spill-over
level of the relevant bath, shower tray or other
fixed appliance’.

REMOVING THE COVER
Note: When you first receive your Aspirante
power shower, the temperature control knob
and cover fixing screws will be packaged
separately within the box. In this instance just
carefully remove the cover and proceed to
‘Plumbing connections’ below.
To remove the cover, first pull off the
temperature control only (fig.6) – not the flow
control.
This will reveal the maximum temperature stop
(fig.7). This should be left in position.
Note: If adjustment of the maximum
temperature stop is required, refer to section
’Adjusting the maximum temperature stop’.
Remove the two cover fixing screws – top and
bottom (fig.8).
Carefully lift the cover away from the backplate.
Lay aside the cover and screws until the unit is
fully installed.
Note: When removing the cover for future
maintenance purposes etc. be aware of the lead
connected to the PCB unit. Carefully pull off the
lead from the PCB.
DO NOT let the cover dangle by the lead.

PLUMBING CONNECTIONS
Plumbing to be completed before wiring
Note: The outlet of the shower must not
be connected to any tap or fitting not
recommended by Triton Plc.
DO NOT use jointing compounds on any pipe
fittings for the installation.
When connecting pipework avoid using tight
90° elbows. Swept or formed bends will
guarantee optimum performance.
Isolate the mains water supply to the cold water
cistern. Drain the hot and cold pipes by opening
all taps.
The hot water supply can be taken from the hot
supply pipe from the cylinder, checking that it is
the first draw-off below the ventilation pipe tee
in order to minimise the effects of water draw-
off elsewhere in the house (see fig.2).
Note: There must not be any other draw-offs
between the take-off point and the shower.
A dedicated cold water supply must be taken
directly from the cold water cistern to the
shower. This draw-off must be positioned
25 mm below the cold feed connection to the
hot water cylinder on the opposite side of the
cistern to the float operated valve (see fig.2).
This minimises air ingress into the pipework.
Plumbing options other than those outlined
in these fitting instructions could impair the
performance. For example, if hot and cold
connections are made after draw-off points
to other outlets, (eg. washing machine, taps,
etc.) it could result in unstable flows and
temperatures should other appliances operate at
the same time.
Run the hot and cold pipework to the shower
position making sure that the pipework does not
rise above the level of water in the cold cistern
at any point to avoid air locks. Under normal site
conditions 15 mm pipework will be adequate.
Decide the position of the shower. Cut the
pipework to the dimensions relevant to the
chosen direction of water entry into the shower.
IMPORTANT: For rear entry only, the supplied
elbows must be used. For ease of installation,
the backplate area adjacent to the top pipe

inlet must be cut out, including the top left
wall fixing hole.
When fitting the elbows to incoming
pipework, check that the elbow collets are
fully engaged with the pipe.
Dimensions are shown in fig.9 and fig.10.
Note: The pipe inlets are marked for hot and
cold connections – left side for hot inlet on
bottom entry (fig.11), but right side for hot
inlet on top or rear entry (fig.12).
IMPORTANT: The fittings on the inlet elbows
are the push-in type. The pipework must
be cut with a pipe cutter and all burrs and
rough edges removed from the end of the
tube. The fittings can be used with copper
and plastic pipe.
If using chrome plated copper pipe, remove
the first 25 mm of plating completely from the
connecting surfaces. If not completely removed
then the collet will not grip the pipe and under
pressure the pipe may be forced out.
Note: Pipework must be clipped or fixed to the
wall so that it cannot be moved or removed
without the aid of a tool.
Note: The pipe inlets contain filters. These
should be periodically removed and cleaned
in order to maintain the performance of the
shower. See section ‘cleaning’ on how to access
the filters.
Two factory fitted blanking plugs are fitted to the
top pipe inlets. These should be left in position if
bottom pipe entry is required. But for top or rear
pipe entry, the two plugs must be removed and
refitted into the bottom pipe inlets.
Insert the pipe removal tool supplied between
the flange of the plug and the grey collet
and lever the plug outward (fig.13). While
holding back on the collet, pull out each
plug by hand. When refitting the plugs in the
bottom pipe inlets, make sure that they are
pushed fully home.

IMPORTANT: The inlets contain check
valves, so before completing the connection
of the water supplies to the shower flush
out the pipework to remove all swarf and
system debris that may cause damage to
internal parts. This can be achieved by
connecting a hose to the pipework and
turning on the water supplies long enough
to clear the debris to waste.

Aspirante thermostatic power shower

FITTING THE SHOWER TO THE WALL
IMPORTANT: Prior to fitting the shower,
make sure that the plumbing is flushed out,
removing all debris, flux, etc.
For top pipe entry or top cable entry, remove
the relevant cut-outs by either breaking out or
by using a knife or junior hack saw (fig.14).
If top entry for both pipe and cable is required,
then additionally remove the shaded area
(fig.14) by using a knife or junior hacksaw.
For bottom pipe entry, remove the cut-out and
break off the two circular parts (fig.15). Replace
the cut-out.
For rear pipe entry only, the supplied elbows
must be used with the necessary portion of
backplate cut away as shown in fig.9.
If rear cable entry is required, conduit or
other routing of the electrical cable must be
completed before fixing the shower to the wall.
Offer the backplate unit up to the completed
pipework and manoeuvre so that the end of the
pipes enter fully into the inlet fittings.
Mark positions for wall fixing holes using
backplate as template (fig.16). Note that four
fixing holes are provided but using only two
should be adequate for most site conditions.
Using the pipe removal tool supplied, push back
and hold the collets from the pipework (fig.17)
in order to disengage pipework from the inlet
elbows.
Remove unit from the wall.
IMPORTANT: Before fitting the shower
to the wall check that the safety earth
contact spring has not been damaged. If
the spring has been damaged then DO NOT
fit the shower and return the appliance for
replacement.
Drill and plug the wall.
(An appropriate drill bit should be used. If the
wall is brick, plasterboard or a soft building block,
appropriate wall plugs and screws should be fitted).

Note: If fitting rising supplies to the unit, make
sure that debris does not enter the pipes when
drilling the wall.
Offer the back plate unit up to the completed
pipework and manoeuvre so that the end of the
pipes enter fully into the inlet fittings. Check
the backplate is square and the fixing holes are
aligned and secure to the wall (fig.16).

Terminal block
Fig.18
IMPORTANT: The earth continuity to the
cover of the shower must be checked and
approved, by a qualified electrician when
the shower is installed, and at least every
2 years thereafter.
ELECTRICAL CONNECTIONS
The supply cable must conform to relevant
tables in current IEE regulations. In most cases
1 mm² twin and earth will be adequate.
The electrical rating of the shower is on the
rating label within the unit.
Cable entry points are shown in fig.1. Conduit
entry can only be from the rear.
Route the cable into the shower, taking care to
avoid the area of the wall fixings and connect to
the terminal block (fig.18) as follows:
Live cable to terminal marked L
Neutral cable to terminal marked N
Earth cable to terminal marked E
IMPORTANT: Fully tighten the terminal block
screws and check that no cable insulation is
trapped under the screws.
Note: The supply cable earth conductor must
be sleeved.
The earth continuity conductor of the electrical
installation must be effectively connected
electrically to all exposed metal parts of other
appliances and services in the room in which the
shower is to be installed, to conform to current
IEE regulations.
Note: Fuses do not guarantee user protection
against electric shock. In the interest of electrical
safety, all mains electric and pumped showers
should be fitted with a 30mA residual current
device (RCD). This may be part of the consumer
unit or a separate unit.
DO NOT switch on the electricity supply until
the water has been turned on to the unit and
connections have been tested for leaks.

COMMISSIONING
THE COVER MAY BE LEFT OFF INITIALLY ONLY
FOR COMMISSIONING.
The first operation of the shower is intended
to flush out any remaining system debris and
to make sure that water is purged through the
unit. This operation must be carried out with the
flexible hose screwed to the shower outlet but
without the showerhead attached.
Direct the outlet of the flexible hose to waste.
Check that the gate valves controlling the water
supply to the unit are fully open. (There is no
need to fit cover at this stage but be aware of
live parts when the electricity is switched on
temporarily).
Fit the temperature control onto the adaptor
(fig.19). This is a push fit and will only fit one
way.
On the PCB, make sure the commissioning link is
positioned on the middle two pins (fig.20).
Switch on electric supply at isolating switch.
Water will begin to flow under gravity pressure.
In order to dispel air and to prime both supplies
to the shower unit, turn the temperature control
several times within its rotational limits.
ONCE RESISTANCE IS FELT, DO NOT FORCE THE
CONTROL FURTHER.
WARNING!
Before normal operation of the
shower, it is essential that the
commissioning and setup procedure
are correctly completed. Failure to
do so could cause the pump to run
dry without water and invalidate
your guarantee.
WARNING!
Be aware of live parts in the unit
when the electricity is switched on.
DO NOT tamper with any parts and
DO NOT deviate from the following
instructions.

Aspirante thermostatic power shower
14
Fig.22
Fig.23
Note: The temperature control rotates less than
one complete turn (fig.21) – from 3 o’ clock
(cold) anti-clockwise to 6 o’ clock position (hot)
and visa versa. DO NOT force it beyond these
limits.
To stop the water flow, switch off the electricity
supply at the isolating switch.
Check for leaks in the pipework and remedy
if necessary. If rear entry has been used then
seal around pipes with mastic to prevent the
possibility of water entering the wall cavity. DO
NOT use plaster as this could cause difficulty if
maintenance is required at a later date.
Setup Procedure
CHECK THE ELECTRICITY TO THE UNIT IS
SWITCHED OFF.
Pull off the temperature control knob.
Remove the commissioning link from the PCB
(fig.22) and store safely for future use.
Offer the cover to the unit. Attached to the flow
control potentiometer inside the cover is a 4-
wire lead. Fit the connector on the end of this
lead to the 4 pins on the PCB (fig.23) – it can
fit either way.

Aspirante thermostatic power shower

REPLACING THE COVER
IMPORTANT:Make sure that the earth
contact spring within the unit is not distorted
before replacing the cover.
Fit the cover, making sure the connector is
fitted to the PCB and the wires are clear of the
setting adaptor. Secure with the top and bottom
fixing screws (fig.24). Make sure the maximum
temperature stop is still in position.
Note: If adjustment of the maximum
temperature stop is required, refer to section
’Adjusting the maximum temperature stop’.
Replace the temperature control knob by push
fitting onto the adaptor shaft, noting that it will
only fit one way.
Check that the flow control is positioned at
‘stop’ (fig.25).
Switch the electricity supply back on at the
isolating switch. Check that both water supplies
are still turned on.
Once the installation of the riser rail is complete,
the shower is ready for normal operation.

TEMPERATURE CONTROL SPINDLE
SETTING
Occasionally the spindle may need adjusting
when the temperature control and cover are
removed from the unit. To reset the spindle
to its correct alignment, please refer to the
following:
With the cover and control knob removed, use
your fingers to adjust the splined spindle until
the small alignment hole drilled into the spindle
lines up with the groove in the top of the valve
spindle housing (fig.26).
Refit the setting adaptor onto the brass splined
spindle aligning the single line on the adaptor
with both the black spindle mark and the
housing groove (the ‘double line’ will be at the
8 o’clock position). The temperature control
location ‘open end’ must relate to ‘5’ on the
temperature scale when the cover is fitted
(fig.27).
Note: Incorrect positioning will result in
excessive cold bleed.

OPERATING THE SHOWER
Make sure all plumbing and electrical supplies
are connected and switched on.
To start the shower, rotate the flow control
clockwise from the ‘stop’ position (fig.28).
Adjust the control until the flow rate is
satisfactory.
For maximum flow, turn the flow control fully
clockwise to the ‘max’ position.
To adjust the temperature, rotate the control
(fig.29). The temperature is numbered for ease
of use. The temperature ranges from ‘1’ – fully
cold to ‘9’ – fully hot.
Once the preferred temperature is reached, no
further adjustment is required, providing the hot
and cold water supplies remain constant.
To stop the shower, return the flow control to
the ‘stop’ position by rotating anti-clockwise
(fig.30). This stops the pump and water flow.
Unless the shower is to be used again
immediately, the shower should also be switched
off at the electricity isolating switch.
As a safety feature, the temperature control
has a built-in stop to prevent you accidentally
exceeding your highest desired temperature. If
adjustment is required see section ‘Adjusting the
maximum temperature stop’.
To override this stop, depress the button
(fig.31) while the control is up against the stop
and turn the control anti-clockwise to the higher
settings (pressing the button before the stop will
not operate the override mechanism even if the
control is turned with the button depressed).
To return to the normal temperature range turn
the temperature control clockwise until it is past
the maximum temperature stop. Make sure
that the temperature control is in the normal
temperature range when the shower is switched
off. The stop comes in a factory set position
based on 65°C stored hot water temperature.
Note: As the flow control is adjusted it is quite
normal for the sound of the pump to alter in
pitch.

ADJUSTING THE MAXIMUM
TEMPERATURE STOP
As a safety feature the shower has a built-in
maximum temperature stop to prevent you
accidentally exceeding your highest desired
temperature. This is set in the factory to provide
a maximum temperature based on the hot
and cold water supplies being 65°C and 15°C
respectively.
Procedure:
Pull off the temperature control (fig.32).
Carefully pull off the maximum temperature
stop mechanism.
To increase the temperature stop setting,
reposition the mechanism anti-clockwise within
the arc of the grooves (fig.33).
To decrease the temperature stop setting,
reposition the mechanism clockwise within the
arc of the grooves (fig.33).
Replace the temperature control by push fitting
onto the adaptor shaft, noting that it will only fit
one way.
IMPORTANT: Only adjust the maximum
temperature stop when the hot water is at its
usual storage temperature.
