connection points.
• Hot water connection: the water temperature must not exceed
60°C.
The water inlet pressure must be between 150 kPa and 300
kPa. Use a pressure reducer if the inlet pressure is above the
maximum permitted level.
9.5 CONNECTION TO THE WATER DRAIN
The water drainage system must be provided using materials
resistant to temperatures of 100 °C. The bottom of the applian-
ce must not be subjected to steam produced by drainage of
hot water. Install a siphoned floor drain with grating below the
water drain cock of Boiling pans and in front of Bratt pans.
10 PANS WITH AUTOCLAVE LID
