1 PLUMBING NOTES
1.1
All installations must comply with the Local
Water Company or Water Undertakers
Byelaws.
1.2 Supply pipes must be flushed to clear debris
before connecting the shower unit (Byelaw
55).
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 the guidance notes contained in
1.1 above.
1.4 DO NOT use excessive force when making
connections to the flexible hose or
sprayhead – finger tightness is sufficient.
1.5 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.
1.6 DO NOT solder pipes or fittings within
300mm of the shower appliance, as heat
transfer can damage components.
1.7 When installed, the top of the shower unit
must be at least 75mm 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.
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 sprayhead.
1.10 A high level hot feed pipe run will result in
air locking and must be avoided.
1.11 Standard gate 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.
1.12 If the shower unit is installed on a common
supply which feeds an adjacent tap, the
maximum static inlet pressure for the unit
will, under certain circumstances be
exceeded. The action of closing the tap can
cause a pulse in the supply pressure which
will result in damage to the unit. This can be
resolved by the installation of a suitably sized
mini expansion vessel, sited as close as
possible to the tap and pressurised to 0.5
bar.
2 ELECTRICAL NOTES
2.1
The installation must comply with
BS 7671 ‘Requirements for electrical
installations’ (IEE wiring regulations) and
Electrical Supply Company regulations.
Ensure 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 3mm 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 It is strongly recommended to fit a 30mA
residual current device (RCD). This may be
part of the consumer unit or a separate unit.

INTRODUCTION
This book contains all the necessary fitting and
operating instructions for your Triton
Aquasensation thermostatic or manual power
shower. Please read them carefully.
Please note that both models are outwardly
similar. The thermostatic version – AS2000T is only
identifiable by having ‘thermostatic’ graphic on
the cover, above the controls. The manual AS2000
shower does not have this graphic and does NOT
contain a thermostatic valve.
Some illustrations in this book depict the
thermostatic model but the instructions will apply
to both models, unless otherwise stated.
The shower installation must be carried out by
suitably competent person and in sequence of this
instruction book.
Care taken during the installation will ensure a
long and trouble free life from your shower
Important: All plumbing connections must be
completed BEFORE making the electrical
connections.
Please read through the whole of this book before
beginning your installation.
Important: The fittings on the pipe inlet elbows
are of 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.
Where chrome plated pipe is used, remove the
first 25mm of plating.
NOTE: The pump inside this product is rated 15
minutes on / 45 minutes off duty cycle.
SAFETY WARNINGS
a
Do not insert fingers into the push-in inlet
fittings. Doing so could cause injury.
b Under no circumstances must this product
be connected to mains cold or hot water
supplies. Failure to comply will invalidate the
guarantee.
c The shower MUST NOT be used if suspected
of being frozen.
d The outlet of this appliance must not be
connected to any form of tap or fitting not
recommended by the manufacturer.
e The sprayhead cartridge must be cleaned
regularly to remove scale and debris.
f This appliance must be earthed.
g Switch off immediately at the isolating switch
if water ceases to flow during use.
h Do not operate the shower outside the
guidelines laid out in ‘site requirements’.
WARNING: The manual AS2000 shower does
not contain a thermostatic valve – it will not
shut off in the event of failure of either the
hot or cold water supplies.
Replacement parts can be ordered from Triton
Customer Service. See ‘spare parts’ for details and
part numbers.
In the interest of electrical safety a 30mA
residual current device (RCD) should be
installed in all UK 230V electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.
Due to continuous improvement and updating,
specification may be altered without prior notice.

SPECIFICATIONS
Hot water temperature
Maximum temperature 80°C.
BS6700 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 (Thermostatic only)
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
1 bar or 10m (supplies must be gravity fed at
nominally equal pressures).
Minimum static inlet pressure
0.0075 bar or 75mm (required to prime the
integral centrifugal pump).

SITE REQUIREMENTS
Water
The installation must be in accordance with Local
Water Company Regulations/Byelaws and BS6700.
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 BS6700.
Do ensure compliance with all the local Water
Company Regulations/Byelaws.

5
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 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

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 so as 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 ensure compliance with
requirements of accessibility of pipes and pipe
fittings.

SITING OF THE SHOWER
WARNING:
THE SHOWER MUST NOT BE
POSITIONED WHERE IT WILL BE SUBJECT TO
FREEZING CONDITIONS.
FOR EASE OF SERVICING, THE APPLIANCE MUST
ALWAYS BE MOUNTED ON THE SURFACE 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
sprayhead.
NOTE: Allow sufficient room between the ceiling
and the shower unit to access the top cover
screw.
Position the shower and sprayhead on the wall so
that all controls can be comfortably reached whilst
using the shower.
The sprayhead and riser rail can be positioned
either side of the shower unit.
NOTE: Water Regulations require the sprayhead
be ‘constrained by a fixed or sliding attachment so
that it can only discharge water at a point not less
than 25mm above the spill-over level of the
relevant bath, shower tray or other fixed
appliance’. The use of the supplied soap dish will
in most cases meet this requirement, but if the
sprayhead can be placed within a bath, basin or
shower tray, then a device must be fitted to
prevent back-flow.
