Important Installation Considerations

1. NOTE: Some showers may not provide an effective shower when used

with gravity fed heated water systems or where pressures are less

than 150kPa at the outlet. Additionally showers with flow rates of less

than 9L/min may not allow the following to function correctly:

_ some instantaneous water heaters

_ some tempering valves

_ some thermostatic mixing valves

2. Some shower heads only operate correctly when hot and cold water

supplies are both mains pressure and may not be suitable for some

instantaneous hot water services.

3. When water pressure is in excess of 500kPa a pressure limiting device

is required in accordance with AS/NZS 3500 1.12 recommendation
