ALL WIRING AND INSTALLATION
MUST BE SUPERVISED BY A SUITABLY QUALIFIED PERSON.
We recommend that the installation be done in the following sequence: -
a) Fix the shower to the wall
b) Plumbing
c) Electrical connections
d) Commissioning
Warning. Do Not Install The Shower In A Room Where It May Be Subject To Freezing
Fix The Shower To The Wall
a)
When deciding where to place the unit a few things need to be taken into consideration: -
1)
The unit must not be mounted directly in the path of the spray from the handset
2)
The handset could be used over a sink for hair washing.
3)
The handset does not come into contact with the used water in the cubicle, bath or basin.
A hose retainer is supplied with the accessories (see separate instructions supplied with
accessories).
4)
Choose a flat piece of wall to avoid the possibility of distorting the backplate and making the
front cover a poor fit.
Remove the three cover screws and lift the cover off.
Remove side section complete with seal.
Depending on which water entry is being used (top or bottom)
break out the relevant rear support rib using a pair of pliers.
(See fig.9)
Identify which pipe and cable entry needs to be cut to enable
the services to enter the shower (top or bottom, no trimming
required for rear entry) then fit them to the backplate.
(See fig.9)
Hold the shower vertically against the wall and mark the top
hole first.
Drill the hole to take the rawl plug provided (taking care to keep
dust away from the shower).
Put the top screw in first leaving it proud by 5mm approx.
The shower can now be hung on this screw.
Position the shower so that it is vertical then mark and drill the other two holes.
Then fix the shower to the wall.
Fix the riser rail with screws provided (see separate instructions supplied with accessories).
Assemble the accessories as shown in the separate instructions supplied with accessories.

How Your Shower Works
1.
Water is heated
instantaneously as it
flows over the heaters in
the plastic heat
exchanger assembly.
2.
The shower
automatically adjusts the
power to the heating
elements and flow of
water to achieve the
selected water
temperature.
The electronics senses
the incoming water
temperature and the flow
of water through the heat
exchanger. It then works
out how many heaters to
switch on so that the
shower temperature
matches the temperature
selected by the buttons.
3.
The amount of hot water
available at the selected
temperature is limited by
the total power of the
heater. The ideal flow
rate is calculated and
adjusted automatically.
4.
The water is turned on and off by the solenoid valve built into the shower.
5.
A stabiliser is built into the flow valve to automatically compensate for small fluctuations in
water pressure that frequently occur in households. There are three further controls to cater for
exceptional reductions in water pressure to prevent the shower from getting too hot.
a) If the flow of water is less than 1.0 l/min the power to the elements is switched off, but the
solenoid valve remains open allowing water to flow through the shower.
b) If the outlet temperature sensor senses an excessive temperature the flow of water and the
heating elements will automatically switch off. The electronics will signal over temperature
condition (see "over temperature shutdown" section).
c) A two stage mechanical thermal cut-out is mounted on the top of the heat exchanger
independent of the electronics. Stage one switches the power off to the elements if it
senses an excessive temperature. The switch operates with an audible click and will reset
if cold water is run through the shower. Stage two only operates if an extreme temperature
is sensed. The cut out will permanently switch off and it will then have to be replaced.
6.
A pressure relief device is fitted to safeguard against other extreme conditions , and provides a
level of appliance protection should an excessive build of pressure occur within the shower.
If this operates a replacement part will be required.
