NOTICE
Use only steam temperature-resistant pipes
for wastewater drainage (e.g. copper, stainless
steel or schedule 80 PVC).
Do not use hoses.
> Unit complies with all relevant regulations
(SVGW, KIWA, WRAS).
> Welding a drain pipe onto the unit drain is not
permitted (will result in damage to the unit).
> Use 2” pipe (1 1/2” for size 60 units) with a
constant gradient (at least 5% or 3°); do not
reduce pipe diameter.
> Recommended: drain should have 1” air gap
and discharge to a floor sink or receptable.
> Observe drain dimensioning requirements:
steam generator short-term pump-off rate =
0,18 gal/s [0.7l/s]
> Average wastewater temperature: 149°F
(adjustable by trained technician in unit set-
tings)
> Applicable standard: DIN 1986, T1
> We recommend integrating a trap into the
wastewater connection in order to optimize
energy consumption.
Tabletop units > Tabletop units may use either a wall drain and
/or a floor drain
> Each unit must have its own wastewater con-
nection (including Combi-Duo).
