Triton ENlight 9.5kW Manual

INTRODUCTION

Please read this book thoroughly and familiarise yourself with all instructions before commencing installation.

Please keep it for future reference.

The shower installation MUST be carried out by a suitably qualified person, in the sequence of these instructions.

ADVICE TO USERS

The following points will help you understand how the shower operates:

1. The temperature controls can be adjusted to provide shower temperatures between 35°C and 45°C (or ambient if cold mode is activated).
2. During winter, the mains water supply will be cooler than in the summer. The water flow rate will therefore vary between seasons, the thermostatic control of the shower unit will automatically maintain the desired temperature.
3. At any selected showering temperature the unit will automatically provide the optimum flow rate possible.

INSTALLATION REQUIREMENTS

PLUMBING REQUIREMENTS

Please read IMPORTANT SAFETY INFORMATION and SPECIFICATION sections before undertaking the plumbing installation.

NOTE: If the recommended dynamic pressure and flow is not available, there could be a noticeable reduction in performance from the shower head.

If it is intended to operate the shower at pressures above the maximum or below the minimum stated, contact Customer Experience for advice.

1. The installation must be in accordance with Water Regulations/Bylaws.
2. DO NOT use jointing compounds on any pipe fittings for the installation.
3. DO NOT solder fittings near the shower unit as heat can travel along pipe work and damage components.
4. Compression or demountable push-fit fittings can be used to connect to the Water Inlet connector.
5. NOTE: DO NOT use non-demountable push-fit fittings as this will prevent servicing and may invalidate the warranty of the product.
6. 
   An additional full bore stop valve (complying with Water Regulations) must be fitted in the mains water supply to the shower as an independent means of isolating the water 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.
7. 
   Before completing the connection of the water supply to the inlet of the shower, flush out the pipe work to remove all swarf and system debris.
8. 
   The unit must be mounted on a flat surface which covers the full width and length of the backplate. It is important that the wall surface is flat otherwise difficulty may be encountered when fitting the cover and subsequent operation of the unit may be impaired.
9. Position of the shower: Refer to Fig.1 for correct positioning of shower. Position the unit where it will not be in direct contact with water from the shower head. Always mount the shower unit vertically and allow enough room between the ceiling and the shower to access the cover top screws.

Water Regulations: It is a legal obligation for the premises owner or occupier to ensure the plumbing work is fully compliant with the water fittings regulations. This means that the shower fittings must provide a 25mm minimum air gap between the shower head and spill over level of a Fluid Category 3 backflow risk (bath, shower tray or basin) and a 30mm minimum air gap for a Fluid Category 5 backflow risk (toilet or bidet) see Fig.1. If these minimum distances cannot be achieved then a double check valve, or similar device, MUST be fitted in to prevent back siphonage of water.

The Shower unit MUST NOT be positioned where it will be subjected to freezing conditions.

ELECTRICAL REQUIREMENTS

Please read IMPORTANT SAFETY INFORMATION and SPECIFICATION sections before undertaking the electrical installation.

The installation, supply cable and circuit protection must conform with BS 7671 (IEE wiring regulations) and be sufficient for the amperage required.

This appliance must be earthed by connecting the supply cable earth conductor to the terminal block within the appliance.

The following notes are for guidance only:

1. The shower unit must only be connected to a 230-240V AC supply. Any drops in voltage due to localised heavy demand may reduce the shower's performance.
2. The electrical rating of the shower is shown on the rating label (Fig.3) which is positioned within the unit.
3. Before making any sort of electrical connection within the installation, make sure that no terminal is live. If in any doubt, isolate the whole installation at the mains supply and remove the correct fuse.
4. The shower unit 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.
5. The electrical supply must be adequate for the loading of the unit and existing circuits.
6. Check your consumer unit (main fuse box) has a main switch rating of 80Amps or above and that it has a spare fuse way which will take the fuse or Miniature Circuit Breaker (MCB) necessary for the shower rating.
7. 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. Contact a professional electrician/local electricity company for advisement.
8. For close circuit protectionDO NOT use a rewireable fuse. Instead use a suitably rated Miniature Circuit Breaker (MCB) or cartridge fuse. Triton recommend the following circuit protection: 8.5KW variant - 40Amp 9.5kW variant - 40/45Amp
9. A 30mA residual current device (RCD) MUST be installed in all UK electric shower circuits. This may be part of the consumer unit or a separate unit. A suitably rated RCBO could be used if the RCD is not present and the consumer is compatible with the RCBO.

Fig.3

10. A 45 amp double pole isolating switch with a minimum contact gap of 3mm in both poles must be incorporated in the circuit. 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.
11. The switch must be accessible and clearly identifiable, but out of reach of a person using a fixed bath or shower tray/cubicle, 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 tray/cubicle. It should be readily accessible to switch off after use.
12. Where shower cubicles are located in any rooms other than bathrooms, all socket outlets in those rooms must be protected by a 30mA RCD.
13. The current carrying capacity of the cable must be at least that of the shower circuit protection (Fig.2). To obtain full advantage of the power provided by the shower, use the shortest cable route possible from the consumer unit to the shower.
14. The electrical circuit to the shower should be separated from other circuits by at least twice the diameter of the cable or conduit. 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 will be necessary to select a larger cable size(Fig.2). In the majority of installations, 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 10mm² cabling throughout the shower installation. 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.

POSITIONING THE SHOWER

For ease of servicing, the unit must always be mounted on the surface of tiled walls.

Never tile up to the unit.

Position the unit where it will not be in direct contact with water from the shower head.

Mount the shower unit vertically.

Allow enough room between the ceiling and the shower to access the top cover screws.

Using the supplied template in the centre of this booklet, mark out the entry points and routing of the water and electric supplies into the shower.

Find our step-by-step installation video for this product on our YouTube channel. Go to youtube.com/TritonShowers and search for 'how to guides'.

Step 3
Complete all the plumbing pipe work.

Ensure that any soldering of pipe work is done away from the shower as heat can travel along pipe work and damage components.

Before connecting the shower to the plumbing pipe work, flush out the pipe work for approximately 60 seconds to remove any swarf or debris.

Step 4
Prepare the shower for fitting to the wall by removing any thinned out sections in the Bottom Corner Trim and Backplate corresponding to the choosen supply entry position.

Step 5
Temporarily connect the shower to plumbing pipe work. Ensure that the unit is level and mark the fixing holes. Use the hole at the top and the 2 holes at the bottom. Remove the shower from the wall. Drill the fixing holes. Use appropriate wall plugs. Reconnect the shower to plumbing pipe work and secure the shower to the wall using appropriate screws.

Ensure the shower is securely fixed to the wall. DO NOT use adhesives as a method of securing the appliance to the wall.

Step 6
Ensure that all pipe connection fittings are tight. DO NOT overtighten. Turn on mains water supply and check the pipe work for any water leakage.


Use a suitable sealant to seal around the rear entry pipe work to prevent water entering the wall.

Step 7
Route the electrical supply cable into the shower unit.

NOTE: The supply cable must be secured either by routing through conduit, trunking or by embedding in the wall, in accordance with IEE regulations. Insert the conductors into the appropriate position on the terminal block.

NOTE: The earth conductor must be sleeved. The outer sheath of any conductor must be stripped back to a minimum. Fully tighten the terminal block screws and make sure that no cable insulation is trapped under the screws.

Loose connections can result in cable overheating. DO NOT switch on the electricity supply.

Step 8
Refit the Bottom Corner Trim

Step 9
SHOWER SETTINGS

Step 10
COMMISSIONING
Attach the appropriate end of the Shower Hose to the shower outlet, using the supplied hose washer seal. DO NOT overtighten. Position the other end of the Shower Hose to the bath or tray waste. DO NOT fit the shower head.

Step 11
During the commissioning process, the electricity supply will need to be switched on, so for safety reasons temporarily fit the cover to the shower. DO NOT connect the wire from the cover to shower unit PCB. Minor adjustment of the Temperature Selector Knob may be necessary to align with the valve. Secure the cover in position with one of the retaining screws.

Step 12
Turn on the water supply to the shower at the isolating stop valve.

Switch on the electricity supply to the shower at the isolating switch.

Water will start to flow from the shower hose.

Allow water to flow for approximately 60 seconds, this will allow the air to bleed from the installation.

Isolate the electricity to the shower at the isolating switch. The water will cease to flow.

Remove the cover retaining screw and lift off the cover.

NOTE: The shower will only run water for approximately 5 minutes. If a longer time period is required, isolate the electricity supply, wait a few seconds then reapply the electricity supply and water will flow for 5 minutes again.

Step 13
Connect the 5-way cable from the Front Cover Assembly to the socket on the Power PCB.

NOTE: The cable connector can only be fitted to the socket one way.

Step 14
Guide the Front Cover Assembly into position. Ensure the Temperature Selector Knob locates correctly onto the valve (minor adjustment of the Temperature Selector Knob may be necessary to align with the valve). Apply slight pressure to the Front Cover Assembly and secure in position with the 4 retaining screws.

Step 15
Install the accessory kit as per the instructions provided with the accessory.

MAINTENANCE

Instructions for Installers and Service Engineers Only

Inlet Filter Maintenance

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.

Switch off the electricity and water supply at the mains.

The inlet filter is situated inside the water inlet fitting.

To gain access to the filter remove the Front Cover Assembly and Bottom Corner Trim. Unscrew the inlet filter cap on the water inlet fitting.

Inspect the O-ring for damage when the filter is removed. Do not over tighten the filter cap on reassembly.

When cleaning the filter mesh, do not use a sharp object as it will cause damage. It is preferable to use an old toothbrush or similar.

FAULT DIAGNOSTICS

Isolate the electricity supply and remove the circuit fuse before attempting any fault finding inside the unit.
