1. Water is heated instantaneouslyas it flows over the
heating elements in the copper cylinder(Diagram 8).
2. The heaters are only switched on when sufficient
water is flowing.
This is done automaticallywith a switch which
works on water pressure and is indicated by the
neon light illuminating depending on the power
selectedby outerknob“A”.
3. The wateris turned on and off by thesolenoid
valve built into the shower.
This is switched on when outer knob “A” is
clicked clockwise.
4. The flow of water isautomatically held at the level set
bythe user even though the supplypressure may vary
(see “Effectof Other Water Deviceson Incoming Water Supply”).
5. Ifthe water supply falls below a set limit, the pressure
switch will operate and switch off the power to the elements.
This is indicated by the neon lightgoing out (see “Effect of Other Water Devices on Incoming
Water Supply”).
6. As afurther safeguard,a thermal cut-out switches thepower off if the water temperature
climbs above the set limit. This cut-out,which gives an audible click, mayalso operate due to
residual heat when the showeris switched off.
It will reset itself ifwater is run through the shower for 10 to 20 seconds.
7. The pressurerelief device is to safeguard against abnormal pressure conditions, and provides a
level of appliance protection should an excessivebuild ofpressure occurwithin the shower.
Effect of Seasonal Incoming Water Temperature Changes
The required water temperature is achieved by adjusting the rate of water flow.
Diagram 9 shows the principle involved in relating temperature rise to flow rate.
The higher the water rate the lower the temperature and vice versa.
The temperature of the watersupplied from the mains can vary considerably
throughout the year from 5 to 20°C.
This means that in the winter, flow rate will be less than in the summer to
achieve the same outlettemperature.
In summer the “ (medium)” power setting may give adequate hotwater.
Effect of OtherWaterDevices on IncomingWaterSupply
Your shower is designed to stabilisetemperature changes caused by waterpressure
fluctuations. These can result from toilets being flushed or taps being turned on and off.
When this happens your showering temperature will be held within a controlled band,provided that
the minimum pressure required by the shower is maintained.
Your shower requires a minimum running
pressure of 69kPa (0.7 bar, 10 psi).
At pressures above 69kPa (0.7 bar,10 psi) itwill minimise temperature fluctuations as detailed
above. If thewater pressure falls below 69kPa(0.7 bar, 10 psi) itis likely that the pressure switch
will turnoff the powerto the heating elements,resulting inacold shower.
This will be indicated by the neon light going out.

WARNING: ALL WIRING AND INSTALLATION MUST BE SUPERVISEDBY A SUITABLY
QUALIFIED PERSON.
WARNING: DONOT INSTALL THIS SHOWER WHERE IT MAY BE SUBJECTED TO
FREEZING CONDITIONS
We recommend that the installation is done in the following sequence.
a. Fixing the showerto the wall b. Plumbing c. Electrical connections
a. FIXING THE SHOWER TO THE WALL
1. Position the riser rail at a convenientheightfor majority of users
as detailed in Diagram 1a and mark itsposition.
2. Position the heater so that the top of the unit is horizontal and level
with, or a maximumof 0.6metres (2ft) belowthe top of the
riser rail. Chooseaflat piece of wall to avoid the possibility of
distorting the backplate thus making the frontcover a poor fit.
3. Adjust the position to get the most convenient arrangement taking
the following into account.
•The heater must not be mounted in the handset direct spray.
•The handset mustnot be able to come into contact with used water
in the cubicle, bath or basin. If it can, evenafter the hose has been
retainedbythe retaining ring (see Diagram 1b), then a vacuum
breaker mustbe fitted (available from us).
4. Fix the riser rail with screws provided.
The fixing holes at thebase of the bracketswill be disclosed by
removing the plastic fronts.Assemble as shown in Diagram 1b.
5. Decide the position of the electrical cable into the unit. If top orbottom entryis chosen
(according to Diagram 7 on page 9), cut away the walls in thebackplate as shown in Diagram 2.
6. Decide the position of entry of the cold waterpipe into the unit.
Iftop, cutawaythe backplate.
If rear, please read the section on plumbing.
Ifbottom, remove the front cover (completewith knobs) andcut away the detachable corner
section as shown.
HOWTO INSTALLYOUR SPA100 SHOWER

7. Ifyou have not yet done so, remove thefront cover assembly byundoing the retaining screws at
the top and bottom of the unit and lifting the cover off.
Your shower is provided with 2 fixing positions in the backplate (see Diagram 7 on page9).
The top-fixing holeis a “key-hole”slot (another key-hole is providedfor alternate fixing), and
should be marked and drilled first.
Tighten top screw with head protruding about 10mm fromthe wall and hook the backplateover
the screw head. This allows for correct and accurate alignmentof your shower before marking
and fixing thebottom position.
You maynot wish to tighten up both screws at this stage as the holesare elongated to allow for
adjustment after otherconnections have taken place.
b. PLUMBING
WARNING: ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS
BELOW BEFORE CONTINUING WITHINSTALLATION.
The heatermust be connected to the mains cold watersupply.
This must have a minimumrunning pressure of 69kPa (0.7 bar, 10 psi)
and a maximum pressure of 690kPa (7.0 bar, 100 psi).
WARNING: BEFORE CONNECTING THE PIPE WORK TOTHE SHOWER,
ENSURE THAT THE PIPE WORKIS FULLY FLUSHED OUT.
1. Unscrewthe “Red Cap” from the shower outletpipe and discard it in a suitable manner.
This has been used to seal the showerduring transit,and is no longer required.
2. Itis recommended that a WRAS (Water Regulations Advisory Scheme) listed isolating valve is
fitted to the incoming mains cold water before the shower unit.
This will allow the unit to be serviced or exchanged without having to turn off thewater atthe
water stop valve.
3. The heater can be fed from a header tank provided this has a minimum head of 7 metres (23ft).
4.
Ø15mm copper orstainless steel pipe shouldbe used.
To avoid cross threading, DO NOT REMOVE the nut
from the elbow whenpositioning the pipe.
Iftop entry is required,turn the elbow 180° into the required position.
Ifrear entry is required, treat as top entry with an additional “Yorkshire” elbow (soldered type)
for fitting into the rearchannel.
In multiple installations, correct pipe work sizes should be calculated to maintain adequate flow
to each shower.
5. Itis permissible to use a WRAS (Water Regulations Advisory Scheme) approved sealant sparingly
whilst avoiding excess finding its wayinto the shower operating parts.
6. With isolating valve connected, flush the pipework through to remove any particles etc,
before making the final connection to the shower.
Blockage in thewaterways (particularly the handset and solenoid valve) will prevent the heater
working properly. Note: You may be charged for aservice call if itis due toincorrect installation.
7. The shower is designed to havean open outlet and should only be used with “Creda”
recommended fittings.
Do not connectthe handsetuntil after the shower front cover and corner section are fitted.
WARNING: DONOT FIT A TAP ON THE SHOWER OUTLET.
