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
aDo 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.
cThe shower MUST NOT be used if suspected
of being frozen.
dThe outlet of this appliance must not be
connected to any form of tap or fitting not
recommended by the manufacturer.
eThe sprayhead cartridge must be cleaned
regularly to remove scale and debris.
fThis appliance must be earthed.
gSwitch off immediately at the isolating switch
if water ceases to flow during use.
hDo 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.

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

5The 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.
6If 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.
7In 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.

REMOVING THE COVER
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 precede wiring
NOTE: The outlet of the shower must not be
connected to anything other than the hose and
sprayhead supplied.
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 ensure
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, ensuring 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 25mm 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 ensuring 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 15mm 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,
ensure the elbow collets are fully engaged with
the pipe.
Dimensions are shown in figs.9 and 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 25mm 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.

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.
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
re-fitted 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). Whilst holding back on
the collet, pull out each plug by hand. When re-
fitting the plugs in the bottom pipe inlets, ensure
they are pushed fully home.

FITTING THE SHOWER TO THE WALL
Important: Prior to fitting the shower, ensure
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.
It will be necessary if rear cable entry is required,
for conduit or other routing of the electrical cable
to 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 collects from the pipework (fig.17)
in order to disengage pipework from the inlet
elbows.
Remove unit from the wall.
Drill and plug the fixing holes to suit the type of
wall and fixing screws supplied. NOTE: If fitting
rising supplies to the unit, ensure 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 (fig.16).
Secure to the wall with fixing screws supplied.

ELECTRICAL CONNECTIONS
WARNING: THIS UNIT MUST BE EARTHED.
ISOLATE THE ELECTRICAL SUPPLY BEFORE
PROCEEDING.
The supply cable must conform to relevant tables
in current IEE regulations. In most cases 1mm2
twin and earth will be adequate.
The electrical rating of the shower is on the rating
label within the unit.
SWITCH OFF THE ELECTRICITY SUPPLY.
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:-
Earth cable to terminal marked E
Neutral cable to terminal marked N
Live cable to terminal marked L
Important: Fully tighten the terminal block screws
and ensure that no cable insulation is trapped
under the screws. NOTE: The supply cable earth
conductor must be sleeved and the cable clamp
(fig.18) used to secure the cable.
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 ensure 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
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.
The first operation of the shower is intended to
flush out any remaining system debris and to
ensure water is purged through the unit. This
operation must be carried out with the flexible
hose screwed to the shower outlet but without
the sprayhead attached.
Ensure the outlet of the flexible hose is directed to
waste.
Ensure 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, ensure 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.
(Once the unit has been commissioned,
disconnect the electricity supply before removing
the commissioning link).
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.
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.
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
ENSURE 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.
Replacing the cover
Fit the cover, ensuring 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.8).
Ensure 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.
Ensure the flow control is positioned at ‘stop’
(fig.24).
Switch the electricity supply back on at the
isolating switch. Ensure both water supplies are
still turned on.
Once the installation of the riser rail is complete,
the shower is ready for normal operation.

and cover are removed from the unit. To replace
the adaptor and to ensure it is located in the
correct alignment, please refer to the following:
AS2000 manual valve
With the adaptor removed, use your fingers to
turn the valve spindle fully anti-clockwise.
Re-fit the adaptor onto the spindle aligning the
single line on the adaptor to the 12 o’clock
position (the ‘double line’will be at the 3 o’clock
position). The temperature control location ‘open
end’must relate to ‘9’ on the temperature scale
when the cover is fitted (fig.25).
NOTE: Incorrect positioning will result in excessive
cold bleed.
AS2000 thermostatic valve
With the adaptor removed, use your fingers to
adjust the brass splined spindle until the black line
on the spindle lines up with the groove in the top
of the valve spindle housing (fig.26).
Re-fit the 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.

FITTING THE RISER RAIL
Decide the position for the rail on the wall within
the shower area. Proceed as follows:
AOffer one of the two brackets to the wall for
the lower position only. Note there are three holes
in the brackets but two screws will usually be
sufficient. However, the centre hole must be used
so mark this and either of the other two. Drill and
plug the wall. Replace the bracket to the wall and
secure to the wall with the screws supplied
(fig.28). Locate the rail onto this lower bracket
ensuring the rail engages fully on the bracket.
Ensure the indent in the riser rail engages into the
cut-out on the bracket end (fig.29).
BLocate the second bracket on top of the rail.
Again mark the centre hole plus one of the other
two holes. Ensure the rail is vertical. Remove the
bracket and rail. Drill and plug the wall.
CWith the saddle, spacer and lever parts to hand,
screw the saddle two or three turns into the lever
(fig.30). Place the saddle and lever into the
slider/holder assembly (fig.31) so that the holes
align, then slide onto the rail (fig.32). Tighten to
the rail by turning the lever. When tight, the lever
should be facing forwards and not pointing to the
wall. If not, slacken off and remove from the rail.
Rotate the saddle and lever 180°within the
slider/holder assembly then replace onto the rail
and tighten. Ensure the tapered thin end of the
spray head holder is in the uppermost position.
DPlace the rail onto the installed lower bracket.
Replace the upper bracket onto the rail and secure
the bracket to the wall with the screws supplied
(fig.33).
EPlace a trim cover onto each bracket ensuring
the large protrusion at the narrow end of the trim
cover, engages into the slot between the rail and
bracket (fig.34) before pushing and clicking the
other end into place (fig.35). Should the need
arise, the trim covers can be removed by inserting
WARNING: Check there are no hidden cables
or pipes before drilling holes for wall plugs.
Use great care when using power tools near
water. The use of a residual current device
(RCD) is recommended.

a screwdriver into the slot and carefully levering
off the trim.
FSnap the soap dish onto the rail (fig.36) below
the holder assembly. Prise open the soap dish
collar and fit onto the rail (fig.37) below the dish.
Note the collar is slightly tapered and should be
fitted ‘thinner section’uppermost. Ensure it
locates firmly in the soap dish (fig.38) so that it
holds the dish at the required height on the rail.
FITTING THE HOSE AND SPRAYHEAD
Feed the flexible hose through the appropriate
soap dish aperture (fig.39) in order that the dish
acts as a retaining ring.
Screw the flexible hose to the shower outlet and
sprayhead (fig.40) ensuring the supplied washers
are in place at both ends of the flexible hose.
Place the sprayhead into the holder (fig.41) and
check that it fits correctly. NOTE: The holder is
slightly tapered and the sprayhead and hose will
only fit from one direction. Important: It is the
conical end of the hose which grips into the
holder. The sprayhead will not fit in the holder
without the hose attached.
TIGHTENING THE SPRAYHEAD
In the unlikely event of the sprayhead dropping
down in use because the holder is loose, this can
be remedied by re-tightening the screw inside the
holder unit. To gain access to this screw, one of
the wall mounting brackets must be removed –
the top one is preferable as the rail can be left in
position on the lower bracket.
First remove the sprayhead and hose from the
holder. Insert a small screw driver into the slot on
the trim cover (fig.42), and carefully prise off the
cover.
Unscrew the fixing screws holding the bracket
and remove it from the wall and rail.
Holding the rail, unlock the lever and slide off the
lever and holder assembly.
Remove the lever and saddle from the
slider/holder assembly. The screw inside the
slider/holder is now accessible.
With an appropriate screw driver, tighten the
screw (fig.43).
Re-assemble in the reverse order.

OPERATING THE SHOWER
Ensure all plumbing and electrical supplies are
connected and switched on.
To start the shower, rotate the flow control
clockwise from the ‘stop’position (fig.44). 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.45). 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.46).
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.47)
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 just
turn the temperature control clockwise until it is
past the maximum temperature stop. Ensure 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.
