any of the following occur:
a) If it is intended to operate the unit at
pressures above the maximum or below the
minimum stated.
b) If the unit shows a distinct change in
performance.
c) If the unit is frozen.

1.7 If it is intended to operate the handwash

in areas of hard water (above 200 ppm
temporary hardness), a scale inhibitor may
have to be fitted. For advice on the Triton
Scale Inhibitor, contact Customer Service.

1.8 The spray rings must be cleaned regularly

with descalent to remove scale and debris,
otherwise restrictions to the flow on the outlet
of the unit will result in higher temperatures
and could also cause the Pressure Relief Device
(PRD) in the unit to operate.

1.9 This product is not suitable for mounting into

steam rooms or steam cubicles.

2 Plumbing

2.1 The plumbing installation must comply

with Water Regulations/Byelaws, Building

Undertakers and in accordance with BS 6700.

2.2 The supply pipe must be flushed to clear

debris before connecting to the handwash.

2.3 DO NOT solder pipes or fittings within

300mm of the appliance, as heat transfer can
damage components.

2.4 DO NOT fit any form of outlet flow control as

the outlet acts as a vent for the heater can.

2.5 DO NOT use excessive force when making

connections to the sprayhead, finger tight is
sufficient.

2.6 All plumbing connections MUST be completed

BEFORE making the electrical connections.

3 Electrical

3.1 The installation must comply with BS 7671

‘Requirements for electrical installations’
(IEE wiring regulations) or any particular

prevent overheating.

3.5 Fuses do not give personal protection against

electric shock.

3.6 To enhance electrical safety a 30mA residual

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

3.7 Switch off immediately at isolating switch if

water ceases to flow during use.

3.8 Other electrical equipment i.e. extractor fans,

pumps must not be connected to the circuits
within the unit.

ADVICE TO USERS

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

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

b. During winter, mains water supply will be
cooler than in summer. Therefore the water
temperature of the unit will vary between
seasons on any one setting of the temperature
control, e.g. if you have chosen setting number
6 as your preferred handwash temperature
in the summer, you may have to increase
that number during winter by adjusting the
temperature control anti-clockwise (which in
effect slows the water flow).

c. The stabiliser valve minimises variations in
water temperature during mains water pressure
changes. If changes in water 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 whilst the unit is in use. If the
pressure drops appreciably below the minimum,
the heating elements will automatically cut out.

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.

If water becomes too hot and you cannot
obtain cooler water, first check that the
sprayhead is not blocked.

2 Before making any sort of electrical

connection within the installation, ensure
that no terminal is live. If in any doubt,
switch off the whole installation at the
consumer unit.

3 The 7kW rated handwash 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.

The 3kW rated handwash can be connected

to a ring main via a 13A fused spur.

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 MCB necessary for the
handwash (fig.3).

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 straight forward
and may require a new consumer unit
serving the house or just the handwash/
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 handwash 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

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 unit must only be connected to a 230-

240V ac supply.

1.1 The electrical rating of the unit is shown on
the rating label (fig.2) within the unit.

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 (MCB) 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 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 of
the 7kW unit.

7.1 It must have a mechanical indicator

showing when the switch is in the OFF
position.

7.2 The wiring must be connected to that

switch without the use of a plug or socket
outlet.

7.3 The switch must be readily accessible and

clearly identifiable, but out of reach of a
person using the unit.

7.4 If the isolating switch is to be fitted in a

bathroom, then it must be a cord operated
type and should be placed so that it is not
possible to touch the switch body when

using the handwash.

7.5 Preferably it should be outside the

handwash area and be readily accessible in
order to switch off after using the unit.

8 The current carrying capacity of the cable

must be at least that of the handwash unit
circuit protection (see table B).

8.1 To obtain full advantage of the power

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

8.2 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.

9 The handwash 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 any event, it is essential that individual

site conditions are assessed by a competent
electrician in order to determine correct
cable size and permissible circuit length.

WATER REQUIREMENTS

The installation must be in accordance with
Water Regulations and Bylaws.

To guarantee activation of the heating elements,
the unit must be connected to a mains water
supply with a minimum running pressure of
100kPa (1.0 bar) at a minimum flow rate of
eight litres/minute and a maximum static
pressure of 1 000kPa (10 bar).

Note: If the stated flow rates are 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 above the unit.
It must be an independent supply to the
handwash unit only.

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

Fig.4 shows a typical system layout for the 7kW
rated handwash unit.

DO NOT use jointing compounds on any pipe
fittings for the installation.
