Note: The boiler should NOT be depressurised by lifting the safety valves and then filled with cold feed water as the stress induced by too rapid cooling may cause damage.

Lưu ý: Các nồi hơi KHÔNG nên depressurised bằng cách nâng van an toàn, sau đó đổ đầy nước thức ăn lạnh như sự căng thẳng gây ra bởi làm mát quá nhanh có thể gây ra thiệt hại.
