3. How Your Shower Works
1. The cold incoming water is heated
instantaneously as it fl ows over the heating
elements in the heat exchanger assembly.
2. At the start up the shower will reach
temperature in 20–30 seconds.
3. The amount of hot water available at the set
temperature is limited by the total power of
the heater.
4. The water is turned on and off by the
solenoid valve built into the shower.
5. A stabilizer built into the water fl ow valve
automatically compensates for small
fl uctuations in water pressure that frequently
occur in households.

SHOWER HANDSET CLEANING
INSTRUCTIONS
The shower handset should be cleaned
periodically to remove lime scale or debris
which will reduce the performance of the
shower. The frequency of the cleaning will vary
according to local water quality.
FILTER CLEANING INSTRUCTIONS
It is recommended that the fi lter is periodically
cleaned in order to maintain the performance of
the shower. It is essential that this operation is
carried out by a competent person.
IMPORTANT: Before servicing, switch off the
electricity supply at the isolation switch.
• Switch off the mains water supply at the
isolation valve.
• The inlet fi lter is situated inside the water
inlet housing.
• To gain access pull the fi lter from the inside
of the inlet housing.
• To reassemble, follow procedure in reverse.
• DO NOT over tighten the fi lter tray on
reassembly.
ATTENTION!
Do not operate the shower unit if the shower head or hose becomes damaged. The shower is
designed and approved to EN-60335 with the shower head provided. Under no circumstances
must any shower head that is not approved by the manufacturer be used with this product also
never fi t any additional device to restrict the water fl ow.

6. A thermal cut-out is mounted on top of the
heat exchanger.
Stage 1 switches the power off to the
elements if it senses an excessive
temperature. The switch operates with an
audible click and will re-set if cold water is
run through the shower.
Stage 2 only operates if an extreme
temperature is sensed. The cut-out will
permanently switch off and will then have to
be replaced.
7. A pressure relief device is fi tted to the
bottom of the heat exchanger body to
safeguard against a build up of pressure
in the heater. It provides protection to the
heater should there be an excessive build
up of pressure occur. If this device operates
then a replacement part will be required.

4. General Installation Layout Guide

• Plan your installation carefully. Check on
the nearest and most accessible rising
main water supply, this may be beneath
the bath or in the loft, where it feeds the
water storage tank. Use only the cold rising
water main.
• If possible avoid connecting the shower
unit where it will be affected by water
drawn off by another appliance.

IMPORTANT!
This appliance can be used by children aged from 3 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge
if they have been given supervision or instruction concerning use of the appliance in a
safe way and understand the hazards involved.
• For example the mains feed to a toilet as
this may cause a drop in pressure to a level
that is too low for the shower unit to work
correctly.
• A WRAS (Water Regulations Advice
Scheme) listed isolating valve must be
fi tted between the rising main and the
unit to comply with water regulations and
to allow for routine maintenance and
servicing.
