DN 40/50 Part number: 8720.1031
> Welding a drain pipe onto the device drain is
not permitted (could result in damage to the
device).
> Use DN 50 pipe (DN 40 for size 60 units) with
a constant gradient (at least 5% or 3°); do not
reduce pipe diameter.
> Observe drain dimensioning requirements:
steam generator short-term pump-off rate =
0.7l/s
> Average wastewater temperature: 65°C
[149°F]
> Applicable standard: DIN 1986, T1
> If floor drain has no odor seal, make sure a
2cm [1" ] free outflow zone is in place.
> We recommend integrating a siphon into the
wastewater connection in order to optimize
energy consumption.
> Unit sizes 60 through 12 may have both a
wall drain and a floor drain
