Before connecting the dishwasher or immediately following disrup-
tion in water supply the water supply pipe must be vented from air
pockets to avoid pressure surges that may destroy components in
the dishwasher.
The quality of the incoming water must correspond to the drinking wa-
ter specification of the country in which the dishwasher is being oper-
ated.
The dishwasher must be connected to the water supply in strict ac-
cordance with current local and national water authority regulations.
The dishwasher is connected to cold or hot water supplies. If hot wa-
ter is not available, the two water inlet hoses (for cold and hot water)
must be connected to the cold water supply via a Y-piece.
The shut-off valves should remain accessible once the dishwasher
has been installed so that the water supply can be shut off whenever
the appliance is not in use.
The dishwasher drainage hose should be connected to a separate on-
site drain for the dishwasher only. If no separate drain is available, we
recommend connecting it to a dual-chamber siphon. When using a
drain loop additional backflow prevention is not required.
If the hose is to be directly connected to the drainage outlet on site,
use the hose clip supplied with the dishwasher.
The on-site connector for the drain hose can be used for various hose
diameters. If the connector extends more than 1" (30 mm) into the
drain hose, it must be shortened. Otherwise, the drain hose can be-
come clogged.
Lay the drain hose so that it does not kink and is not being sub-
jected to pressure or tugged.
If the on-site drain connection is situated lower than the guide path
for the lower basket rollers in the open door, a siphoning effect during
a program can cause the appliance to empty itself of water.
In this case, lay the drain hose with a bend in it so that its highest
point is at least level with the guide path for the lower basket rollers.
Up to two dispensing systems for liquid cleaning agents and rinsing
agents can be connected to the back of the dishwasher. Appliances
with integrated dispensing systems have an external connection for
rinsing agents.
