Water drainage
–
The drain is equipped with a
non-return valve which prevents
waste water from flowing back into
the commercial dishwasher through
the drain hose.
–
The commercial dishwasher drain
hose should be connected to a
separate drain for the commercial
dishwasher only.
If no separate drain is available, we
recommend connecting it to a
dual-chamber siphon.
– The commercial dishwasher is
equipped with a 1.5 m flexible drain
hose with an internal diameter of
22 mm.
Connecting clamps are provided
with the commercial dishwasher.
– An additional hose and adapter can
be used to extend the drain hose.
The drain hose length must not
exceed 4 m and the pumping height
must not exceed 1 m!
–
The drainage system must be able to
accommodate a minimum drainage
flow of 16 l/min.
–
The drain hose must not be
shortened!
,
Make sure the hose is not
kinked, squashed or pulled too tight.
Venting the drainage system
The drain must be vented if the
connection to the building' s drainage
system is lower than the roller guides
for the lower basket in the door.
Otherwise the water inside the
commercial dishwasher may siphon out
during the wash program.
For venting:
^
Open the commercial dishwasher
door completely.
^
Pull the lower spray arm up to
remove.
^
Cut off the cover of the vent valve in
the wash cabinet.
