7 TECHNICAL SPECIFICATION
Stuart Turner reserve the right to amend the specification in line with its policy of
continuous development of its products.
Note: For information on other voltages/frequencies which are not shown, consult any
supplementary instruction sheet supplied, or the rating label attached to the
pump.
*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 minimize deposition of scale in hard water areas.
Maximum permissible water temperature 65°C.
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).
