ADVICE TO USERS

The following points will help you understand
how the shower operates:

a. The electric heating elements operate at a
constant rate at your chosen power setting. It is
the rate of the water passing through the heater
unit which determines the shower temperature
at a given setting. (The slower the flow the
hotter the water becomes, and the faster the
flow the cooler the water).

b. During the winter the cold water supply
will be cooler than in the summer months.
Therefore, the temperature of the water will
vary from season to season on any one setting
of the control buttons, e.g. if you have chosen
'Economy' power for your preferred shower
temperature in the summer, you will have
to select the 'High' setting and adjust the
temperature control during the winter months.

c. The stabiliser valve minimises variations in
shower temperature during mains water pressure
changes. If changes in shower temperature are
experienced during normal use, it will most
likely be caused by the water pressure falling
near to or below the minimum level. The drop
in pressure may be due to water being drawn
off at other points in the house whilst the
shower is in use. If pressure drops appreciably
below the minimum, the heating elements will
automatically cut out.

If ever the water becomes too hot and
you cannot obtain cooler water, first
check the showerhead has not become
blocked.

ELECTROMAGNETIC COMPATIBILITY

This product is intended for domestic

use.

This product may temporarily be affected
by electromagnetic disturbance near to
the installation that could cause temporary
operation of the low pressure indicator
together with switching to the cold power
selection. If problems persist, contact Triton
Customer Service (see rear page).

IMPORTANT: When first installed (or
following replacement of the PRD), the
unit will be empty. It is essential the
heater assembly contains water before
the elements are switched on. As this
unit has electronic control, 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

The installation, supply cable and circuit
protection must conform with BS7671 (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.4) 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 consumer unit.

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.5).

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 circuit and
carry out what is necessary. They will also
check the main bonding.

5 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.

5.1 All exposed metallic parts in the bathroom

must be bonded together using a cable of
at least 4mm2 cross sectional area. These
parts include metal baths, radiators, water
pipes, taps and waste fittings.

6 For close circuit protection DO NOT use a

rewireable fuse. Instead use a suitably rated
miniature circuit breaker or cartridge fuse
(see table A).

6.1 In the interest of electrical safety a 30mA

residual current device (RCD) should be
installed in all UK electric and pumped
shower circuits. This may be part of the
consumer unit or a separate unit.

7 A 45 amp double pole isolating switch with

a minimum contact gap of 3mm in both
poles must be incorporated in the circuit.

7.1 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.

7.2 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.

8 Where shower cubicles are located in any

rooms other than bathrooms, all socket
outlets in those rooms must be protected
by a 30mA RCD.

9 To obtain full advantage of the power

provided by the shower, use the shortest
cable route possible from the consumer
unit to the shower.

9.1 The current carrying capacity of the cable
must be at least that of the shower circuit
protection (see table B).

9.2 It is also necessary to satisfy the
disconnection time and thermal
constraints which mean that for any given
combination of current demand, voltage
drop and cable size, there is a maximum
permissible circuit length.

10 The shower circuit should be separated

from other circuits by at least twice the
diameter of the cable or conduit.

10.1 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.

10.2 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 10mm² cabling throughout the shower
installation.

10.3 It is essential that individual site conditions
are assessed by a competent electrician
to determine correct cable size and
permissible circuit length.

WATER REQUIREMENTS

The installation must be in accordance with
Water Regulations/Bylaws. To ensure activation
of the heating elements, the shower must be
connected to a mains water supply with a
minimum running pressure of 100 kPa (1.0 bar)
at a minimum flow rate of nine litres per minute.

For the 10.5kW rated shower, the minimum
running pressure must be 150 kPa (1.5 bar) at a
minimum flow rate of eleven litres per minute.

For all units the maximum static pressure must
be 1000 kPa (10 bar).

If in any doubt, the pressure should be checked.

Note: If the stated flow rate is not available,
it may not be possible to achieve optimum
performance from the unit throughout the year.

The water supply can be taken from a cold water
storage cistern provided there is a minimum
head of ten metres (fifteen metres for the

10.5kW model). Minimum head is the vertical

distance from the base of the cistern to the
showerhead. It must be an independent supply
to the shower only.

If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service for
advice.

SITING OF THE SHOWER

IMPORTANT: If installing onto a tiled wall
always mount the unit on the surface of the
tiles. NEVER tile up to the unit.

Refer to Fig.11 and Fig.12 for correct siting of
the shower.

Position the control panel where it will NOT
be in direct contact with water from the
showerhead. Position the remote pack vertically
and is accessible for maintenance purposes.

Note: Water Regulations requires that 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 hose
retainer will usually meet this requirement, but
if the showerhead can be placed within a bath,
basin or shower tray, then a double check valve,
or a similar device, must be fitted in the supply
pipework to prevent back-flow.
