The Kelda KC13A145 shower system is a ground breaking, patented technology that injects water into an air stream to deliver a unique “real rain” effect showering experience. This provides a shower force equivalent to twice that of a conventional shower, thereby offering water savings of over 50%* and associated water heating energy savings.

The Kelda KC13A145 shower system is designed to be installed with a concealed hydraulic push button water valve (not supplied).

General arrangement — refer to diagram on page 6.The shower head and back plate vent (1) is installed within the shower area against a bulkhead wall. The blower module (2) and digital control module (3) are installed behind the bulkhead wall in the service void. An electrical supply is required to be connected to the digital control module (3)

via a 30mA RCD device. Electrical connections between the digital control module (3) and blower module (2) is made through a simple connector plug and socket (4).

Water supply from a group thermostatic mixer control (not supplied) is plumbed to the hydraulic push button water valve (not supplied). The outlet of this valve is then plumbed to the blower module water inlet connection via the hose supplied. The outlet water connection of the blower module (2) is connected to the shower head water inlet using the hose supplied.

Air is supplied to the shower head from the air outlet connection of the blower module (2) with the hose supplied. Warm air from the shower area is returned to the blower module (2) via the back plate vent and hose supplied.

The digital control unit requires a 100-230V 50/60Hz single phase supply. It is Class I equipment and requires an earth connection. A 30mA RCD is required for each digital control module.

All electrical installation to be carried out by an approved electrician in accordance with Part “P” U.K. Building Regulations and to the latest IEEE standards, or the appropriate regulations in the country of installation.

E L E C T R I C A L C O N N E C T I O N

Before plugging the appliance into the mains socket, make sure that:

• The socket is earthed and in compliance with the applicable law • The socket is able to sustain the shower’s maximum power load indicated on the technical data plate fixed to the digital control module • The supply voltage is included within the values indicated on the technical data plate fixed to the digital control module • The socket is compatible with the plug fitted to the shower. If this is not the case, replace the socket or the plug

Your shower is supplied with a 5 amp plug. It can be fitted into an electrical socket protected with a 30mA RCD for immediate use. Before installation, please read the following instructions.

Theshowermustbeearthed.Thefollowingoperationsshouldonlybecarriedoutbyaqualifiedelectrician.WARNING!

R E P L A C I N G T H E F U S E

When replacing a faulty fuse, a 5 amp ASTA approved fuse to BS 1362 should always be used, and the fuse cover re-fitted. If the fuse cover is lost, the plug must not be used until a replacement is obtained.

R E P L A C E M E N T F U S E C O V E R S

If a replacement fuse cover is fitted, it must be of the correct colour as indicated by the coloured marking or the colour that is embossed in words on the base of the plug.

R E M O V I N G T H E P L U G

Should you wish to re-route the mains cable through partitions or similar, please ensure that either:

• The plug is replaced by a fused 5 amp rewireable plug bearing the BSI mark of approval or; • The mains cable is wired directly into a cable outlet, protected by a 30mA RCD and a 5A switched fuse, (in compliance with BS 5733) which is accessible without moving the shower.

11

WARNING!

D I S P O S I N G O F T H E P L U G

Ensure that before disposing of the plug itself, you make the pins unusable so that it cannot be accidentally inserted into a socket.

Instructions for connecting cable to an alternative plug: Important: the wires in the mains lead are coloured in accordance with the following code:

Green & yellow EarthBlue NeutralBrown Live

As the colours of the wires in the lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

• Connect green & yellow wire to the terminal marked E or (earth symbol) coloured green or green & yellow. • Connect brown wire to terminal marked L or coloured red • Connect blue wire to terminal marked N or coloured black • If a 5 amp plug (BS 3163) is used, it must be fitted with a 5 amp fuse, either in the plug or adapter or at the distribution board.

If you are in any doubt regarding the electrical supply to your shower, consult a qualified electrician before use.

D I S P O S I N G O F T H E D I G I TA L C O N T R O L M O D U L E

When disposing of the digital control module, remove the plug by cutting the mains cable as close as possible to the plug body and dispose of as described earlier.

O P E R AT I O N1. Turn on the water isolation valve.

2. Turn on the electricity supply.

3. Check the digital control module for power. (The “standby power” indicator should be illuminated). The Kelda Technology system operates by detecting water flow. It starts when water flow is detected and stops when the water flow ceases.

4. Press the hydraulic push button flow valve. Water should start to flow from the shower head, followed very quickly by the air flow (the blower LED will illuminate). Once the water valve times out, the water will cease to flow. If the air overrun function is selected, the air will continue for a few seconds to purge the shower head.

Congratulations,you’renowreadytoexperiencethegreenestshowerintheworldandstartsavingwaterandenergy costs.

FA C T O R Y S E T T I N G S

Your Kelda shower has been factory set for water flow at 4.5 litres per minute and is the equivalent of a standard 9 litres per minute standard shower. This is set via a flow regulator fitted within the shower head.

The rate at which the air is delivered to the shower is factory set for optimum water/air ratio.

The system has an air overrun function which allows the air to continue to operate for approximately 1-2 seconds after the water flow stops. This function purges the water from the shower head, reducing the build up of limescale.
