INSTALLATION

General

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

conducted by designated, qualified and competent personnel.

The installation must comply with the “Water Supply Regulations 1999 (Water Fittings)”

or any particular regulations and practices, specified by the local water company or

water undertakers.

Note! Make sure that all site requirements correspond to the information given in the

section: ‘Specifications’.

Caution! The shower must not be installed in an area where it may freeze.

For stud partitions alternative fixings may be required.

1. Isolating valves must be installed close to the valve for ease of maintenance.

2. Pipework must be rigidly supported and avoid any strain on the connections.

3. Pipework dead-legs should be kept to a minimum.

4. Supply pipework layout should be arranged to minimise the effect of other outlet

usage upon the dynamic pressures at the valve inlets.

5. Inlet and outlet threaded joint connections should be made with PTFE tape or

liquid sealant. Do not use oil-based, non-setting joint compounds.

6. To eliminate pipe debris it is essential that supply pipes are thoroughly flushed

through before final connection.

7. Determine the route for the hot and cold supply pipework and for the outlet pipework.

When connecting to the biv shower fittings it is recommended that the outlet be

positioned above and to one side of the shower control. This is to prevent the

flexible hose from obstructing the temperature and flow knobs of the shower

control.

8. Decide on a suitable position for the

shower control. The position of the

shower control and the shower fittings

must provide a minimum gap of

25 mm between the spill-over level of

the shower tray/bath and the handset.

This is to prevent back-siphonage. For

further information on the installation

of your shower fittings, refer to the

Discovery Fittings Installation and User

Guide.

Note! Only use shower fittings

recommended by the manufacturer or

supplier.
