Connecting the drain hose
– A non-return valve is incorporated into the drain system in the ma-
chine to prevent drainage water flowing back into the machine via
the drain hose.
– The machine drainage hose should be connected to a
separate
drain for the machine only. If no separate drain is available, we re-
commend connecting it to a dual-chamber siphon.
– The on-site connection point,
measured from the lower edge of
the machine
, should be positioned at a height between 0.3 m and
1.0 m. If it is lower than 0.3 m, the drain hose must be laid in a coil
at a height of at least 0.3 m.
– The drainage system must be able to accommodate a minimum
drainage flow of 16 l/min.
– The drainage hose is approx. 1.4 m (Australia and New Zealand:
2.25 m) long and flexible with an internal diameter of 22 mm. Hose
clips for the connection are supplied.
– The drain hose must not be shortened.
– The drain hose can be extended using a connection piece to attach
a further length of hose up to 4.0 m long. The drainage length must
not exceed 4.0 m.
– Drainage noise can be considerably reduced if the drainage hose is
positioned in an arc at a minimum height of 0.6 m and a max.
height of 1.0 m measured from the bottom edge of the washer-dis-
infector.
