SECTION ONE
Important Information
Your shower is designed and tested to the
very highest standards and complies fully
with
all of the relevant national/intemational
standards for safety and reliability.
The shower
is manufactured in a
BS
EN ISO 9002-registered factory your
assurance
of a quality product.
To ensure correct use and maintenance of
the shower, please read and adhere to the
following warnings and guidelines.
For Installers:
1.1 Do not attempt any of the electrical or
plumbing work necessary to install this
product unless you have
good practical
experience and adequate understanding
of
the lEE Wiring Regulations and Water Bye-
Laws.
1.2 WARNING: THIS APPLIANCE
MUST BE EARTHED.
1.3 Before removing your shower heater
cover always ensure your shower heater is
isolated from the electrical mains.
1.4 This product is splash-proof, and is
approved for use
in shower cubicles and
over baths. However,
do not install the
shower heater
in a position where the
handset, in its normally-parked position, will
consistently direct spray over it.
1.Sa We strongly recommend that you fit
an isolating valve in the pipework to the
shower,
in an accessible place. This will be
of great benefit if any maintenance work, or
complete replacement of the shower, is
required later on.
1.Sb This shower is designed for domestic
use and
is not vandal-resistant. If it is installed
in an institutional or commercial situation,
frequent inspection may
be necessary, and
our guarantee may
be affected.
a
For Users:
1.5 If water emerges from anywhere other
than the spray head outlets,
do not use your
shower, and refer to the fault-finding section.
1.6 IT IS IMPORTANT TO CLEAN
THE HANDSET SPRAY PLATE
REGULARLY, particularly
in hard water
areas, where this may
be necessary as
often as
once a week. Failure to do so will
affect the performance
of the shower, and
in extreme cases may cause the pressure
relief device
to operate.
Refer
to Section 6.
1.7 The shower heater outlet, hose
and handset act as a vent. They
must not be blocked, obstructed, or
have connected to them any fitting
not approved by us. The use of
unapproved accessories may invalidate the
guarantee and affect the performance and
safety
of the unit.
1.8 WARNING: DO NOT USE the shower
if the HOSE
IS DAMAGED in any way; for
instance if the outer covering has parted to
reveal the inner tube. A damaged hose can
suddenly restrict the flow and result
in
extremely hot water from the spray head.
A damaged hose could completely block
the outlet
of the shower; the resulting
increase
in pressure could burst a
weakened
or damaged hose.
1.9 Do not install the shower in a situation
where the water
in it could freeze. Any
damage caused
by freezing will not be
covered by the guarantee.
If you suspect your shower is
frozen, SWITCH OFF IMMEDIATELY.
Refer to Fault-Finding, Section Five.
1.10 Do not leave young children, the infirm
or the disabled unattended
in the shower.
1.11 Before stepping into the shower,
always test the temperature of
the spray
with your hand.
1.12 Switch off at the isolating switch
after use. This is a safety procedure
recommended with
ALL electric appliances.

1.13 As with all electrical appliances, it is
recommended to have your shower and
installation checked
at least every two years
by a competent electrician,
to ensure there
is no deterioration due to age and usage.
1.14 Shampoo and shower gel should be
stored using the gel hook and soap dish
(where provided) and
must not be
placed on top of the shower unit.

How an instant electric
shower works
r 1.15 In an instant electric shower, an
electric element heats water AS IT PASSES
THROUGH. The temperature of the shower
is adjusted by controlling the rate at which
water flows over the heating element. This
is done using a flow control knob. There
is
no thermostat. If the temperature ofthe
incoming water varies (mains water can be
as low as 5° C
in the winter and as high as
20° C
in summer), the output temperature
will also
vary. The shower is only able to
RAISE the temperature of the water by a
given amount (depending upon the flow
rate).
