DRAIN CONNECTION
The drain vent assembly, included with the unit,
and a 50,8mm (2") pipe with standard drain pitch,
should be run to an open drain or connected to a
standpipe equipped with a vent. The waste water
can also be directed to a nearby floor drain.
Please use the drain vent assembly and a
50,8mm (2") pipe for drain connection. Flexible
hose which allows trapped water to accumu-
late in sagged runs must be avoided.
