Drain
Waste pipes coming from different parts of the equipment must not be
combined. They must be piped separately to the floor drain without
restriction or back-pressure.
Comply with local regulations relating to waste water (addition of
formalin, temperature restrictions, etc.).
• Run the drain pipe(s) with a fall towards the floor drain, where it/they
must terminate at a distance of at least two pipe diameters above the
highest water level of the water trap, but at least 20 mm (1”) above
the water level (dimension A). Pipes less than 1.5 m (5 ft) long
require only a minimal fall.
• Design the waste pipes for short duration temperatures of about
100
o
C (212°F)..

Plastic waste pipes should be avoided, as a loss of cooling
medium may result in the outlet being exposed to waste
water at 100°C (212°F) for a long time.
