b)The heater 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.
4.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.
5.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 6.
6.Decide the position of the cold water pipe into the unit. If top or bottom entry is chosen, carefully cut away the relevant walls of the backplate as shown in diagram 6. If bottom entry is chosen refer to note 4 in the plumbing section.
7.If you have not yet done so, remove the front cover (complete with knobs) by undoing the retaining screws at the top and bottom of the unit. Your shower is provided with three fixing positions in the backplate (see diagram 6). The top fixing hole is a

WARNING : - UNDER NO CIRCUMSTANCES SHOULD THIS UNIT BE CONNECTED TO THE MAINS COLD WATER SUPPLY.
The heater should be connected to a cold water supply gravity fed 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 cm (3") and a maximum head of 10 metres (33ft).
It is strongly advised to install the shower unit using an independent supply from the cold water storage cistern. 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. Therefore the cold water supply should be taken directly from the cold water cistern.
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.
1.It is recommended that a water council listed isolating valve is fitted between the cold water storage cistern and the shower unit. This will allow the shower unit to be serviced without turning off the cold water at the water stop valve and draining the cold water cistern.
2.15mm copper pipe should be used. Ensure all burrs have been removed from the pipes before inserting into the push fit inlet ports. Diagram 8 illustrates the correct procedure for inserting and removing the pipes from the inlet ports.
Take care to line up the inlet pipe correctly with the inlet port to avoid straining the internal 'O' ring seal.
DO NOT use solder fittings within 300mm of plastic fittings.
3.To maintain the optimum performance, the pipe runs should be kept as short as possible, using sweeping bends rather than right angles or restrictive fittings.
4.If bottom entry has been chosen, the inlet port must be rotated through 1800 into the required position. To do this unscrew the side section from the shower unit (see diagram 6). Rotate inlet connection ensuring that a snug fit into the cradle is achieved, replace side section retaining screw and remove the side section and tighten screw.
5.With an isolating valve connecting, flush the pipework through to remove particles etc. before making the final connection to the shower. A blockage in the waterways (particularly the spray rings and filter) will prevent the shower unit working properly.
