unit ie. Mounted as shown in diagrams 5/6. Choose a flat piece of wall to avoid possibility of distorting the backplate thus making the front cover a poor fit.

3.Adjust the positions to get the most convenient arrangement taking the following into account : -

a)The possible need to use the handset over the sink for hair washing etc.

b)The shower unit must not be mounted in the direct spray from the handset.

c)The handset must not be able to

come into contact with the used water in the cubicle, bath or basin. If it can, even after the hose has been retained by the hose retainer (see diagram 12), then a vacuum breaker must be fitted. It should be noted that these devices are liable to minor leakage so they must be positioned so that any drips are not detrimental

3.Fix the riser rail with screws provided.

The fixing holes at the base of the brackets will be revealed by removing the plastic fronts. Assemble as shown in diagram 12.

4.Decide the position of the electrical cable to the unit. If top or bottom entry is chosen, carefully cut away the relevant walls of the backplate as shown in diagram 7.

5.Decide the position of the water pipes into the unit. If top or bottom entry is chosen, carefully cut away the relevant walls of the backplate as shown in diagram 7. If bottom entry is chosen refer to note 8 in the plumbing section.

6.If you have not yet done so, remove the front cover by undoing the retaining screws at the top and bottom of the unit. Remove Temperature Control Knob 'B' cap (see dia.1) by levering out carefully with a small flat bladed screwdriver and remove the small fixing screw as shown in diagram 14. Your shower is provided with four fixing positions in the backplate (see diag. 2). The top fixing holes are key-hole slots and the most convenient should be marked and drilled first. Tighten top screw with head protruding about 10 mm from the wall and hook the backplate over the screw head. This allows for correct and accurate alignment of your shower before marking and fixing the bottom positions. You may not wish to tighten up the

screws at this stage as the holes are elongated to allow adjustment after other connections have taken place.

WARNING : - UNDER NO CIRCUMSTANCES SHOULD THIS UNIT BE CONNECTED TO THE MAINS COLD WATER SUPPLY.

The shower unit should be connected to a gravity fed water supply from a static cold water cistern with a minimum capacity of 114 litres (25 galls). There must be a minimum head of water of 8.0cm (3'') and a maximum head of 10.0 metres (33ft).

It is strongly advised that the shower unit is installed using independent supplies from the cold water storage cistern and hot water cylinder. The shower would then be totally unaffected by other draw off points elsewhere in the system and thus the pressure and temperature will remain more stable. The cold water supply should be taken directly from the cold water storage cistern and the hot water supply should be taken from the hot water cylinder via an Essex or Surrey flange (see diagram10).

Under no circumstances should any of the pipework supplying the shower unit rise above the level of the bottom of the cold water cistern. Before connecting the pipework to the shower ensure that the pipework is flushed out.
