ADVICE TO USERS
The following points will help you understand how the shower operates:
a. The electric heating elements operate at a constant rate at your chosen power setting. It is the rate of the water passing through the heater unit which determines the shower 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 temperature of the shower will vary between seasons on any one setting of the temperature control, e.g. if you have chosen setting number 6 as your preferred shower temperature in the summer, you will have to increase that number during winter by adjusting the temperature control clockwise (which in effect slows the water flow).
c. The stabiliser valve minimises variations in shower temperature during mains water pressure changes. If changes in shower 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 in the house whilst the shower is in use. If pressure drops appreciably below the minimum, the heating elements will automatically cut out.
If ever the water becomes too hot and you cannot obtain cooler water, first check that the sprayplate in the shower head has not become blocked.
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.

ELECTRICAL REQUIREMENTS
WARNING! THIS APPLIANCE MUST BE EARTHED
The installation, supply cable and circuit protection must conform with BS 7671 (IEE wiring regulations) and be sufficient for the amperage required.
The following notes are for guidance only:
1 The shower must only be connected to a 230-240V ac supply. If you are installing a shower with a kilowatt rating above 9kW, it is advisable to contact the local electricity supply company.
1.1 The electrical rating of the shower is shown on the rating label (Fig.3) within the unit.
2 Before making any sort of electrical connection within the installation, make sure that no terminal is live. If in any doubt, switch off the whole installation at the mains supply and remove the correct fuse.
3 The shower 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.
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 Miniature Circuit Breaker (MCB) necessary for the shower (Fig.4).
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 straightforward and may require a new consumer unit serving the house or just the shower.
4.2 You will need to contact the local electricity company. They will check the supply and carry out what is necessary.
5 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).
5.1 A 30mA residual current device (RCD) MUST be installed in all UK electric and pumped shower circuits. This may be part of the consumer unit or a separate unit.

6 A 45 amp double pole isolating switch with a minimum contact gap of 3mm in both poles must be incorporated in the circuit.

6.1 It must have a mechanical indicator showing when the switch is in the OFF position, and the wiring must be connected to the switch without the use of a plug or socket outlet.

6.2 The switch must be accessible and clearly

able, but out of reach of a person

u

xed bath or shower, except for the

cord of a cord operated switch, and should

be placed so that it is not possible to touch

the switch body while standing in a bath or

shower cubicle. It should be readily accessible

to switch off after using the shower.

7 Where shower cubicles are located in any rooms other than bathrooms, all socket outlets in those rooms must be protected by a 30mA RCD.

8 The current carrying capacity of the cable must be at least that of the shower circuit protection (see Table B).

8.1 To obtain full advantage of the power provided by the shower, use the shortest cable route possible from the consumer unit to the shower.

8.2 It is also necessary to satisfy the disconnection time and thermal constraints which means that for any given combination of current demand, voltage drop and cable size, there is a maximum permissible circuit length.

9 The shower 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 the majority of installations (see Table B), the cable will unavoidably be placed in one or more of the above conditions. This being so, it is strongly recommended to use a minimum of 10mm cabling throughout the shower installation.

9.3 In any event, it is essential that individual site conditions are assessed by a competent electrician in order to determine the correct cable size and permissible circuit length.

1. Measure the width of an individual strand, and half that measurment to find (r), e.g: 1.34mm ÷ 2 = (r) 0.67mm
2. Multiply (r) x (r) x 3.14, e.g: (r) 0.67 x (r) 0.67 x 3.14 = 1.41mm2
3. Multiply this by the number of wire strands (usually 7), e.g: 1.41mm2 x 7 = 9.87mm2.
4. The number obtained would suggest 10mm2 wiring.
*PLEASE NOTE: If unsure, consult a qualified Electrician.

WATER REQUIREMENTS
WARNING!
The shower must not be positioned where it will be subjected to freezing
conditions.
The installation must be in accordance with Water Regulations and Bylaws.
To guarantee activating the heating elements, the shower 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 per minute for the 8.5kW rated model, and nine litres per minute for the 9.5kW rated model.
For the 10.5kW rated shower, the minimum running pressure must be 150kPa (1.5 bar) at a minimum flow rate of eleven litres per minute.
For all models the maximum static pressure must not exceed 1000kPa (10 bar).
Note: If the stated flow rates are not available, it may not be possible to achieve the best performance from the unit throughout the year.
During periods of high ambient temperatures it may be necessary to select a low power setting to achieve your preferred shower temperature.
The water supply can be taken from a cold water storage cistern provided there is a minimum head of ten metres above the shower head. It must be an independent supply to the shower only.
If it is intended to operate the shower at pressures above the maximum or below the minimum stated, contact Customer Service for advice.
Fig.5 shows a typical system layout.
DO NOT use jointing compounds on any pipe fittings for the installation.

Electric shower

SITING OF THE SHOWER
IMPORTANT: If installing onto a tiled wall always mount the unit on the surface of the tiles. NEVER tile up to the unit.
Refer to fig.6 for correct siting of shower.
Position the unit where it will NOT be in direct contact with water from the shower head. Position the shower unit vertically.
Leave enough room between the ceiling and the shower to allow access to the cover top screws.
Note: Water Regulations require the shower head be `constrained by a fixed or sliding attachment so that it can only discharge water at a point not less than 25mm above the spill-over level of the relevant bath, shower tray or other fixed appliance’. The use of the supplied retaining ring/gel hanger will in most cases meet this requirement, but if the shower head can be placed within a bath, basin or shower tray, then a double check valve, or similar, must be fitted in the supply pipework to prevent back-flow.
Pressure relief safety device
A pressure relief device (PRD) is designed into the shower unit which complies with European standards. The PRD provides a level of appliance protection should an excessive build up of pressure occur within the shower.
DO NOT operate the shower with a damaged or kinked shower hose, or a blocked shower head which can cause the PRD to operate.
When commissioning, the shower head must be removed from the flexible hose, while at the same time the temperature control must be at the minimum flow position. Failure to follow this procedure may also cause the PRD to operate.
Make sure the shower is positioned over a bath or shower tray because if the PRD operates, then water will eject from the bottom of the unit.
Should this happen, turn off the electricity and water supplies to the shower at the isolating switch and stopvalve. Contact Customer Service for advice on replacing the PRD.

WARNING! Check there are no hidden cables or pipes before drilling holes for wall
plugs. Use great care when using power tools near water. The use of
a residual current device (RCD) is recommended when using power tools.

Note: The control knobs are an integral part of the cover ­ DO NOT attempt to remove them.
Lift the cover from the backplate and remove the trimplate.
Entry positions for the mains water and electric cable are from the top, bottom, either side or from the back.
Note: Deviations from the designated entry points will invalidate product approvals.
If a bottom entry has been chosen, the pipe trim on the bottom of the cover should be removed (fig.7).
If a top entry has been chosen, the pipe trim on the top of the backplate should be removed (fig.8).
If a side entry is required, the trimplate side will have to be cut. With the elbow compression fitted on the outlet, temporarily place the trimplate into position, then mark the pipe entry on the side of the trimplate. Carefully remove the appropriate area using a junior hacksaw.

Fig.9

Please note: NONE of the ‘cut outs’ are designed to ‘snap out’. DO NOT remove
using pliers as the backplate or lower trimplate could be damaged.
A junior hacksaw or suitable knife should be used and any rough edges removed.
Damage to the backplate or lower trimplate will invalidate product
specifications and warranty.

11

Electric shower
If installing a feed pipe from the back or bottom, the centre of the inlet valve to the wall surface is 20mm (fig.9).
Note: If entry is from the back, the nut of the compression fitting will be partially behind the surface of the wall. This area MUST be left clear when plastering over the pipework in order to make the nut accessible for future adjustments.
After choosing the site for the shower, use the backplate as a template and mark the two fixing holes (fig.10).
Drill and plug the wall. An appropriate drill bit should be used. If the wall is plasterboard or a soft building block, appropriate wall plugs should be fitted.
Screw the top fixing screw into position leaving the base of the screw head protruding 6mm out from the wall.
Hook the backplate over the bottom screw and fit the top fixing screw into position.
DO NOT fully tighten the screws at this stage, as the fixing holes are elongated to allow for out of square adjustment after the plumbing connections have been completed.

Electric shower

WARNING!
The outlet of the shower acts as a vent and must not be connected to anything other than the hose and
shower head supplied.

PLUMBING CONNECTIONS
Plumbing to be carried out before wiring DO NOT use jointing compounds on any pipe fittings for the installation.
DO NOT solder fittings near the shower unit as heat can transfer along the pipework and damage components.
Standard 15mm x 15mm brass compression fittings MUST be used to connect to the inlet of the shower.
Note: An additional stopvalve (complying with Water Bylaws/Regulations) MUST be fitted in the mains water supply to the shower as an independent means of isolating the water in order to carry out maintenance or servicing. If this isolator is fitted in a loft space, the loft must have a fixed access ladder and be boarded, with appropriate lighting from the access point to the isolator.
IMPORTANT: Before completing the connection of the water supply to the inlet of the shower, and in compliance with Water Regulations, flush out the pipework to remove all swarf and system debris. To do this, connect a hose to the pipework and turn on the mains water supply long enough to clear the debris to waste.
Procedure Turn off the water supply either at the mains stopvalve or the isolating stopvalve. Connect the mains water supply to the inlet of the shower via 15mm copper, stainless steel or plastic pipe using a 15mm x 15mm brass compression fitting.
Note: The inlet fitting is designed to enter a compression fitting only. DO NOT use push fit connectors as full engagement cannot be guaranteed. DO NOT use excessive force when making these connections.
Make sure the backplate is square on the wall and tighten the two retaining screws which hold it to the wall.
Turn on the mains water supply and check for leaks in the pipework connection to the shower. IMPORTANT: Using a suitable sealant, always seal around the incoming pipework to prevent water entering the wall.
Note: At this stage no water can flow through the unit.

COMMISSIONING
WARNING! Before normal operation of the shower, it is essential the following commissioning
procedure is completed correctly.
The first operation of the shower is intended to flush out any remaining unit debris and to make sure the heater unit contains water before the elements are switched on. This operation must be carried out with the flexible hose screwed to the outlet but without the shower head attached. Make sure the outlet of the flexible hose is directed to waste. · Before turning on the electric and mains
water supplies to the shower, make sure that the power selector is at the STOP position (fig.16). · Select the minimum flow position (fig.17).
Note: Failure to turn the control to the minimum flow position may cause the PRD to operate. · Turn on the mains water supply to the shower at the isolating stopvalve and then turn on the electric supply to the shower at the isolating switch. The power indicator will light. · Turn the power selector to the COLD position (fig.18) and wait until water starts to flow from the flexible hose. · Slowly rotate the temperature control fully anti-clockwise to the maximum flow position (fig.19). It will take about thirty seconds for a smooth flow of water to be obtained while air and any debris is flushed from the shower. · When a smooth flow of water is obtained, rotate the temperature control from minimum to maximum several times to release any trapped air within the unit. · Once flushing out has been completed, stop the water flow by turning the power selector to the STOP position. · Fit the shower head to the flexible hose and place in the shower head holder.
The shower is now ready for normal operation.

To start the shower

Turning the power selector to the red or blue

Cold

symbol positions will start water to flow.

To stop the shower
Switch the power selector to the STOP position and water will cease to flow.

WARNING!
If restarting immediately after stopping, be aware that a slug of hot water will be
expelled for the first few seconds.

To use the power selector
The power selector has four positions – stop, cold, economy and high as shown in fig.20. · Stop is to switch off the electric and water
supply at the shower – no flow or power used. · Blue symbol is for cold water only. · Red single symbol is the economy setting
for using less power during warmer months. Temperature adjustment at this setting is via the temperature control. · Red double symbol is the high setting which allows the highest flow achievable for your preferred temperature.
Adjustment of the temperature control on the COLD setting will only alter the force of the water from the shower head. It will not alter the water temperature.
Note: If the stated flow rate required for the unit cannot be met due to low water pressure, it will be necessary to operate the unit on `economy’ setting during the warmer months because of flow rate limitations entering the unit.

Electric shower
To adjust the shower temperature
Alter the water temperature by increasing or decreasing the flow rate of the water through the shower via the temperature control (fig.21).
After obtaining your preferred showering temperature, the position can be remembered and left as the normal setting and should only need to be altered to compensate for seasonal changes in ambient water temperature. Note: The preferred number on ECONOMY’ will give a different temperature to the same number position onHIGH’.
To decrease the shower temperature
Turning the temperature control anti-clockwise (fig.21) will increase the flow of water through the shower making it cooler.
To increase the shower temperature
Turning the temperature control clockwise (fig.22) will decrease the flow of water through the shower making it warmer.
Note: It is advisable to be certain that the showering temperature is satisfactory by testing with your hand before stepping under the shower head. There will always be a time delay of a few seconds between selecting a flow rate and the water reaching the stable temperature for that flow rate.
CAUTION: It is recommended that persons who may have difficulty understanding or operating the shower controls should not be left unattended while showering. Special consideration should be given to young children and the less able bodied.

Note: In normal use, it is in order to leave the water supply permanently on to the shower unit, but as with most electrical appliances, the unit must be switched off at the isolating switch when not in use.

OPERATING FUNCTIONS
Power on indicator (fig.23)
When the electricity supply to the shower is switched on at the isolating switch, the POWER indicator will light.
Note: Should the safety cut-out device operate, the indicator will remain lit.
Low water pressure cut-out
If the water pressure falls below the minimum required for correct operation of the shower, power will be switched off to the heating elements preventing any maintained temperature rises (water will continue to flow). Power will automatically be restored when adequate water pressure returns. TP ­ Temperature Protection
During normal operation if the temperature exceeds the showering safety limit the power to the elements will be removed completely, although water will continue to flow. When the temperature has cooled sufficiently, power to the elements will be automatically restored to the settings at the time of interruption.
Safety cut-out
The unit is fitted with a non-resettable thermal cut-out safety device. In the event of abnormal operation which could cause unsafe temperatures within the unit, the device will disconnect the heating elements. It will require a visit from a qualified engineer to determine the nature of the fault and replace the safety device once the unit has been repaired.

WARNING – CLEANING
Triton recommends that all products are cleaned using warm, soapy water.
Do not use abrasive or aggressive chemical cleaning products as this may affect the product surface finish and
invalidate your guarantee.

INSTRUCTIONS FOR INSTALLERS AND SERVICE ENGINEERS ONLY

CLEANING THE INLET FILTER
It is recommended that the filter 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 mains.
Switch off the water supply at the lsolator valve.
Remove the cover. The inlet filter is situated in the inlet pipe, which is part of the solenoid valve (fig.24).
To access the filter, remove the trimplate then disconnect and remove the compression fitting.
Also, depending on the incoming pipework arrangements, if there is not enough slack in the pipework, it could mean the removing the unit from the wall.
When cleaning the filter, DO NOT use a sharp object as it will cause damage. It is preferable to use an old toothbrush or similar.
Note: Full commissioning procedure will need to be performed after cleaning of the filter (see page 16 for information on commissioning procedure).
