Appliances equipped with pump drainage system shall be so designed that when the pump is blocked the
temperature of the oil circuit at the hottest point of the pump with which oil is in contact shall not exceed
230 °C in the test conditions of 7.8.101. This requirement is deemed to be satisfied if the maximum winding

mechanism(s) of the cover shall be designed to prevent any unintended opening when the appliance is
working under pressure.
For appliances that operate with a pressure higher than the atmospheric, it shall not be possible to open
the cover until the pressure has reached a value near the atmospheric pressure. Any de-pressurizing shall
be safe and under control.
Pressurized appliances shall incorporate a vacuum release device to prevent a partial vacuum forming,
unless they are designed for vacuum operation.
