User guide

Installation must be carried out in accordance with these instructions, and must be

conducted by designated, qualified and competent personnel.

1. The hose retaining ring supplied must be used to stop the handset from dropping

below the spill-over level of the bath or shower tray. This will prevent water supply

contamination due to backsiphonage.

2. Installations must comply with UK Water Regulations/ Bye-laws (Scotland), and

Building and Plumbing Regulations in force at the time of installation.

3. When installing the shower fittings in a cubicle, position with the spray pointing

across rather than toward the opening of the cubicle.

4. When installing the shower fittings over a bath, position with the spray pointing

down the centre line of the bath.

5. Avoid layouts where the shower hose will be sharply kinked. This may reduce the

life of the hose.

6. Do not fit any form of flow control in the shower outlet.

7. Do not use excessive force when making connections.

8. Do not install the fittings in a position where it could become frozen.

9. The minimum pressure required for a satisfactory spray pattern to form, at the

handset or spray head, is 0.1 bar. For a gravity fed shower installation the minimum

head of water required, to accommodate the pressure loss in the pipes and shower

control of a typical installation, is 1.0 metre.

For a pump installation the minimum acceptable vertical distance between the

base of the cold water storage cistern and the shower head to operate the pump’s

flow switches, is typically 0.6 m (600 mm).

High and Low Capacity Nozzle Rings

1. All shower fittings are supplied with low capacity nozzle rings fitted as standard

to the handset or shower head. High capacity nozzle rings, with larger spray

holes, are also included in the fittings pack.

The low capacity nozzle rings will be suitable for low pressure installations. However

for high pressure installations the spray force may be too powerful for comfortable

showering. In such situations it is recommended the high capacity nozzle rings

are fitted. Refer to the section: High Capacity Nozzle Ring Installation for

fitting instructions.

2. For gas water heaters which require a higher flow rate to operate correctly, it is

recommended the high capacity nozzle rings are fitted.
