The following points will help you to understand how your MX shower unit operates.

The flow rate of water passing through the shower unit determines the water temperature. The lower the flow the warmer the water, the higher the flow the cooler the water.

The temperature produced by the shower unit will vary between seasons on any one setting of the temperature control. This is due to variance in the temperature of the water supply, which becomes cooler in winter than summer.

The stabiliser valve maintains an almost constant shower temperature during mains water pressure changes.

If changes in temperature are experienced in normal use, it is likely to be caused by water pressure falling below the minimum level. Falls in water pressure may be due to water being drawn off at other points within the building.

In instances of difficult joints use P.T.F.E.

Tape. The use of compound invalidates

the guarantee.

The shower head must be cleaned regularly to remove scale and debris. If the water becomes hot and you are unable to obtain cooler water, check the spray head for blockage.

SHOWER INSTALLATION

A TYPICAL INSTANTANEOUS ELECTRIC SHOWER INSTALLATION

The shower unit should be positioned so that the shower head cannot be immersed in the bath or shower tray when hanging down.

Mains cold water supply

(either top, bottom or rear entry)

Plan your own installation carefully. Check on the nearest and most readily accessible rising mains water supply, this may be beneath the bath or in the loft, where it feeds the cold water storage tank. Use only the cold rising water main supply.

Do not connect the shower unit to

the down service from the tank.

Avoid connecting the shower unit, if

possible, were it will be affected by water

drawn off by other appliances, e.g. From

the mains feed to the W.C., This may

cause a drop in pressure too low for the

shower unit to work correctly.

An isolating valve must be fitted into the

water supply for servicing purposes.

Position your shower unit on the wall away from the direct spray of the shower and at about the same height as the shower head position.

Remove the two screws securing the shower unit cover and remove the cover complete with the control knobs.

Place the shower unit on the wall and mark the location of the fixing screws through the back plate.

Carefully drill the holes as marked using a sharpe 5.5mm masonry drill.

Fix the shower unit to the wall using the plugs and screws provided, do not fully tighten at this stage.

IMPORTANT

To comply with National Water

Council bylaws a double check valve must be fitted with all flexible shower accessories where it is possible that the shower head may come into contact with used water i.e. In the bath or shower tray.

Plumbing the shower unit must precede wiring.

Turn off the water supply at the isolating stop tap.

Determine the direction of the inlet water supply: Top (falling), Bottom (rising), or

Back inlet.

Connect the mains water supply to the inlet of the shower unit using a 15mm copper or stainless pipe with a 15mm compression

Elbow or 15mm push-fit elbow. Do not use excessive force when making the connection to the unit.

The back plate and the trim plate are fitted with removable inserts for fitting over the pipework to the shower unit.

Warning! This appliance must be earthed

The shower unit must be permanently connected to the electricity supply, direct

From the consumer unit via a double pole linked switch with a minimum contact gap of 3mm. The switch must be readily accessible and clearly identifiable and out of reach of a person using a fixed bath or shower tray, unless the switch is cord operated. The wiring must be connected to the switch without the use of a plug or socket outlet.

The cable size required is determined by the kW rating of the shower and the distance between the shower and the consumer unit. The table above will help you choose the correct cable for your installation, but it will depend upon the precise circumstances of the installation. If you are in any doubt consult an electrician.

The incoming cable should be hidden.

IMPORTANT

Before turning on the water supply to the shower unit the water supply pipe should be flushed out to remove debris. This can be achieved by connecting the flexible hose to the

INSTRUCTIONS

Secure the cover with the two fixing screws provided.

IMPORTANT

Turn the flow control knob anti- clockwise until the valve is fully open before switching on the unit.

This will ensure a fast fill up of the unit when the shower is first switched on.

TIPS

A piece of insulating or masking tape applied to the wall before marking out the Fixing holes will help stop the drill from wandering, particularly on tiled surfaces. When working near a basin or bath, insert the plug in the waste fitting so that small parts cannot be lost.

Take care not to drop accessories or tools into basin or bath.

Switch on the power to the shower unit at the consumer unit and the double pole switch. At this stage the power selector knob should be on the STOP position.

Remove the shower head from the fexible hose and point to waste.

Turn the top power selector knob to the

The showerhead should be cleaned periodically to remove limescale or debris which will reduce the performance of the shower. The frequency of cleaning will vary according to local water quality.

PERIODICAL MAINTENANCE

1.To break away scale deposits on a daily basis simply rub your thumb over the surface whilst the shower is running.

2. Some showerheads are fitted with self clean probes, to help the removal of limescale. These probes can be activated by rotating the lever clockwise.

3. If scale deposits are stubborn, soak the showerhead in a proprietary limescale remover and rinse thoroughly before use.

ATTENTION!

Do not operate the shower unit if the sprayhead or hose becomes damaged.

Warning: If re-starting the shower immediately after stopping, be aware that a slug of hot water will be expelled for the first few seconds.
