overflow must be connected to a lifting station which
pumps the water up to sewer level in case of
overflow. See also section
overflow.
Place the RMQ unit as follows:
• In a room with floor drain.
• At least 40 cm below the ceiling, measured from
the top of the unit. This distance is necessary to
be able to carry out maintenance and service
work, if required.
