7 TECHNICAL SPECIFICATION
Stuart Turner reserve the right to amend the specification in line with its policy of
continuous development of its products.
*Note: Max working pressure is the maximum pressure that can be applied to
the pump internal casing under any installation conditions.
**Note: In normal circumstances the temperature of stored water should never
exceed 65 °C. A stored water temperature of 60°C is considered
sufficient to meet all normal requirements and will minimise deposition of
scale in hard water areas.
7.11 Noise: The equivalent continuous A-weighted sound pressure level at a distance
of 1 metre from the pump does not exceed 70 dB(A).
