ADVICE TO USERS
The following points will help you understand
how the shower operates:
a)
Temperature/flow rate
The temperature control can be adjusted to
provide shower temperatures between 35°C
and 47°C.
Alternatively, adjusting a temperature stop
mechanism inside the unit to 38°C, 41°C
or 43°C maximum can restrict the shower
temperature.
Important
: To comply with BEAB care
mark requirements the unit must not be
able to run hotter than 41°C (this is used in
healthcare or special needs environments).
The T150Z pumped unit is factory set at
47°C (see page 16) on how to adjust the
MAXIMUM temperature stop to 41°C
or below.
At a selected showering temperature the unit
will provide the optimum flow rate possible.
Note the maximum flow rate for the given
temperature will be greater in the summer
than in the winter because of the variance in
the ambient mains water supply.
Should water pressure/flow to the shower be
insufficient for optimum performance then
the unit will operate at a reduced power level
and provide the highest flow rate possible for
the given shower temperature.
b)
Temperature stabilisation
The shower will maintain temperature in
accordance with the BEAB care mark.
If ever the water becomes too hot, and you
cannot obtain cooler water, first check that
the sprayplate in the showerhead has not
become blocked.
DO NOT place items such as soap or shampoo
bottles on top of the unit. Liquid could seep
through the joint between the cover and backplate,
and possibly damage the sealing rubber.
Important: When first installed the unit
will be empty. It is essential the unit should
contain water before the elements are
switched on. It is vital that the commissioning
procedure is followed. Failure to carry out this
operation will result in damage to the unit
and will invalidate the guarantee.

ELECTRICAL REQUIREMENTS
Shepperton Park,
Triton Road, Nuneaton,
Warwickshire, CV11 4NR
The installation, supply cable and circuit
protection must conform with BS 7671 (IEE
wiring regulations) and be sufficient for the
amperage required.
The following notes are for guidance only:
1 The shower must only be connected to a
230-240V ac supply. If you are installing a
shower with a kilowatt rating above 9kW, it
is advisable to contact the local electricity
supply company.
1.1 The electrical rating of the shower is shown
on the rating label (Fig.3) within the unit.
2 Before making any sort of electrical
connection within the installation make sure
that no terminal is live. If in any doubt,
switch off the whole installation at the mains
supply and remove the correct fuse.
3 The shower must be connected to its own
independent electrical circuit. IT MUST NOT
be connected to a ring main, spur, socket
outlet, lighting circuit or cooker circuit.
3.1 The electrical supply must be adequate for
the loading of the unit and existing circuits.
4 Check your consumer unit (main fuse box)
has a main switch rating of 80A or above
and that it has a spare fuse way which will
take the fuse or Miniature Circuit Breaker
(MCB) necessary for the shower (Fig.4).
4.1 If your consumer unit has a rating below
80A or if there is no spare fuse way, then the
installation will not be straightforward and
may require a new consumer unit serving
the house or just the shower.
4.2 You will need to contact the local electricity
company. They will check the supply and
carry out what is necessary.
5 For close circuit protection DO NOT use a
rewireable fuse. Instead use a suitably rated
Miniature Circuit Breaker (MCB) or cartridge
fuse (see Table A).
5.1 A 30mA residual current device (RCD) must
be installed in all UK electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.

5.1 A 30mA residual current device (RCD) must
be installed in all UK electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.
6 A 45 amp double pole isolating switch with
a minimum contact gap of 3 mm in both
poles must be incorporated in the circuit.
6.1 It must have a mechanical indicator showing
when the switch is in the OFF position, and
the wiring must be connected to the switch
without the use of a plug or socket outlet.
6.2 The switch must be accessible and clearly
identifiable, but out of reach of a person
using a fixed bath or shower, except for the
cord of a cord operated switch, and should
be placed so that it is not possible to touch
the switch body while standing in a bath or
shower cubicle. It should be readily
accessible to switch off after using the
shower.
7 Where shower cubicles are located in any
rooms other than bathrooms, all socket
outlets in those rooms must be protected by
a 30mA RCD.
8 The current carrying capacity of the cable
must be at least that of the shower circuit
protection (see Table B).
8.1 To obtain full advantage of the power
provided by the shower, use the shortest
cable route possible from the consumer unit
to the shower.
8.2 It is also necessary to satisfy the
disconnection time and thermal constraints
which means that for any given combination
of current demand, voltage drop and cable
size, there is a maximum permissible circuit
length.
9 The shower circuit should be separated from
other circuits by at least twice the diameter
of the cable or conduit.
9.1 The current rating will be reduced if the
cabling is bunched with others, surrounded
by thermal loft or wall insulation or placed in
areas where the ambient temperature is
above 30°C. Under these conditions,
derating factors apply and it is necessary to
select a larger cable size.

9.2 In the majority of installations, the cable
will unavoidably be placed in one or more
of the above conditions. This being so, it
is strongly recommended to use a
minimum of 10mm cabling throughout
the shower installation.
9.3 In any event, it is essential that individual
site conditions are assessed by a competent
electrician in order to determine the correct
cable size and permissible circuit length.

To ensure activation of the heating elements,
the shower must be connected to a cold water
supply which is Gravity Fed Only from a static
cold water storage cistern with a minimum
capacity of 114 litres (25 gallons).
There must be a maximum head of water of
10 metres and a minimum head of 8 cm as
measured between the bottom of the cistern and
the top of the shower unit. There must be no
other cold water draw-offs between the cistern
and the unit and the pipe must not supply water
to any other tap or fitting at a lower level.
Note: The supply pipe from the cistern should be
on the opposite side to the float operated valve
to prevent air being drawn into the pipe when
the cistern is filling.
If it is intended to operate the shower in
hard water areas (above 200 ppm temporary
hardness) a scale inhibitor should be fitted.
Fig.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe
fittings for the installation.
WARNING!
Under no circumstances must
this shower be connected directly
to the mains water supply.

SITING OF THE SHOWER
For ease of servicing, the unit must always be
mounted on the surface of tiled walls. Never
tile up to the unit.
Refer to (Fig.6) for correct siting of shower.
Position the unit where it will not be in direct
contact with water from the showerhead.
Position the shower unit vertically.
Allow enough room between the ceiling and the
shower to access the cover top screws.
Note: Water Regulations (shower hose
connections) requires the showerhead 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
showerhead can be placed within a bath, basin
or shower tray, then a double check valve, or
similar, must be fitted in the supply pipework to
prevent back-flow.
Pressure relief safety device
A pressure relief device (PRD) is designed into
the shower unit which complies with European
standards. The PRD provides a level of appliance
protection should an excessive build up of
pressure occur within the shower.
Do not operate the shower with a damaged or
kinked shower hose, or a blocked showerhead
which can cause the PRD to operate.
When commissioning, the showerhead must
be removed from the flexible hose. Failure to
follow this procedure may also cause the PRD to
operate.
Make sure the shower is positioned over a bath
or shower tray because if the PRD operates, then
water will eject from the bottom of the unit.
Should this happen, turn off the electricity and
water supplies to the shower at the isolating
switch and stopvalve. Contact Customer Service
for advice on replacing the PRD.
WARNING!
The shower must not be
positioned where it will be subjected
to freezing conditions.
Fig.6

IMPORTANT: The unit must be mounted on
a flat surface which covers the full width
and length of the backplate. It is important
that the wall surface is flat otherwise
difficulty may be encountered when fitting
the cover and subsequent operation of the
unit may be impaired.

T150Z pumped thermostatic electric shower
Note: The control knobs are an integral part of
the cover – DO NOT attempt to remove them.
Unscrew the two top and bottom two retaining
screws (fig.7) and lift the cover from the
backplate.
Entry positions for the mains water and electric
cable are from the top, bottom, or from the
back.
Note: Deviations from the designated entry
points will invalidate product approvals.
If bottom entry has been chosen, fit the
appropriate cut-out in the top of the backplate
(fig.8).
If top entry has been chosen, fit the appropriate
cut-out in the bottom of the cover (fig.9).
After choosing the site for the shower, use the
Installation Template supplied to mark the four
fixing holes, the position of which are shown in
(fig.7).
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).
Screw the top two fixing screw into position
leaving the base of the screw head protruding
6mm out from the wall.
Hook the backplate over the top of the two screw
and fit the other fixing screws into position.
DO NOT fully tighten the screws at this stage,
as the fixing holes are elongated to allow for
out of square adjustment after the plumbing
connections have been completed.

PLUMBING CONNECTIONS
Plumbing to be carried out before wiring
DO NOT use jointing compounds on any pipe
fittings for the installation.
DO NOT solder fittings near the shower unit
as heat can travel along pipework and damage
components.
Compression fittings Must be used to connect to
the inlet of the shower.
Note: An additional stopvalve (complying with
Water Regulations) Must be fitted in the water
supply to the shower as an independent means
of isolating the water in order to carry out
maintenance or servicing.
Important: Before completing the connection
of the water supply to the inlet of the shower,
flush out the pipework to remove all swarf
and system debris. This can be achieved by
connecting a hose to the pipework and turning
on the water supply long enough to clear the
debris to waste.
Procedure
Turn off the water supply isolating stopvalve.
Connect the water supply to the Inlet of the
shower via 15mm copper, stainless steel or plastic
pipe using a 15mm x 15mm compression fitting,
see (fig.10) for advice on Rear Entry fitting.
Note: If installing a feed pipe from the
back, the use of a soldered Elbow connector
is recommended. It should be positioned
approximately 105mm from the inlet
connector centre. The centre of the inlet
valve to the wall surface is 21mm.
