1.Surrey Flange (Top entry cylinder flange) Fitting Instructions. The hot connection to the Shower unit can be taken directly from the hot cylinder using a Surrey Flange. Diagram 10 shows how this flange should be fitted.

2.Essex Flange (Side entry cylinder flange) Fitting Instructions. Alternatively, the hot connection to the Shower unit can be taken directly from the hot cylinder using an Essex cylinder flange and extension pipe.

Diagram 10 explains how the flange should be fitted.

Connecting direct to the side of the cylinder is not recommended where a top entry immersion heater is fitted.

3.The hot connection can also be taken from the hot supply to other outlets as shown in diagram 11. The connection must be made below the ventilation pipe tee.

4.In all cases a dedicated cold water supply should be taken from the cold water cistern to the shower unit. The connection in the cistern should be made below the level of the cold water feed to the hot water cylinder. The connection should also be on the opposite side of the cistern to the float valve. This will prevent air being sucked into the pump chamber.

5.It is recommended that water council listed isolating valves are fitted between the cold water storage cistern and the shower unit and between the hot water cylinder and the shower unit (see diagrams 10/11). 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.

6.15mm copper pipes should be used. Ensure all burrs have been removed from the pipes before inserting into the push fit inlet ports. Diagram 9 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.

DO NOT insert fingers into the push-fit inlet ports. Doing so could result in injury.

7.Keep pipe runs as short as possible and use swept bends rather that right angled or restrictive fittings to optimise the performance.

8.If bottom entry has been chosen, the inlet port must be rotated through 1800 into the required position. To do this unscrew the combined inlet elbow (as shown in diagram 8) and remove the side section from the shower unit. Remove combined elbow and rotate for bottom entry. Slide back into position ensuring that the 'O' seals are correctly in place. Replace side section and tighten 2 screws in elbow to lock into position.
