DE DIETRICH WBD1211 - Manual (Page 20)

Installation should comply with local
water authority and building
regulations’ requirements.
The appliance must be given a
separate cold water supply and not be
connected to a mixer tap, a single
outlet water heater or a booster pump.
A minimum water pressure of 0.48 bar
is required for safe operation of the
appliance.
The inlet hoses must not be
lengthened. If they are too short and
you do not wish to move the taps, you
will have to purchase new, longer
hoses specially designed for this type
of use.
Water drainage
The end of the drain hose can be
positioned in three ways:
Hooked over the edge of a sink
using the plastic U-piece supplied
with the machine. In this case, make
sure the end cannot come unhooked
when the machine is emptying.
This could be done by tying it to the
tap with a piece of string or attaching
it to the wall.
P0022
In a sink drain pipe branch. This
branch must be above the trap so that
the bend is at least 60 cm above the
ground.
Directly into a drain pipe at a
height of not less than 60 cm and not
more than 90 cm.
The end of the drain hose must
always be ventilated, i.e. the inside
diameter of the drain pipe must be
larger than the outside diameter of the
drain hose.
The drain hose must not be kinked.
Run it along the floor; only the part
near the drainage point must be
raised.
The drain hose may be extended to a
maximum of 4 metres. An additional
drain hose and joining piece is
available from our Service Agent.
Important
Before connecting up the machine to
new pipework or to pipework that has
not been used for some time, run off a
reasonable amount of water to flush
out any debris that may have
collected in the pipes.

Installation
Any necessary adjustment can be
made with a spanner. Accurate
levelling prevents vibration, noise and
displacement of the machine during
operation.
Some vibration is inevitable,
especially if mounted on a wooden
floor.
Sprung wooden floors are particularly
susceptible to vibration. For advice,
consult a builder. If possible, always
place the machine on a solid floor.
Special conditions
If the floor is carpeted or covered with
crumbly or soft material, insert a rigid
support base under the feet to prevent
noise, vibration or displacement. The
base should protrude a few
centimetres beyond the edges of the
machine.
Warning
The machine should NOT be
placed on deep pile carpeting.
P1051
Note
Please ensure that when the
appliance is installed it is easily
accessible for the engineer in the
event of a breakdown.
Water inlet
The appliance has two inlet hoses,
hot and cold, with female 3/4” BSP
thread connectors. If this connection
is not compatible with the plumbing of
the existing installation, a variety of
connectors are available from good
hardware stores and plumbers
merchants to suit most domestic
plumbing. Any alteration to your
existing plumbing must be carried out
by a competent person, or qualified
plumber.
The inlets on the back of the
appliance are colour coded, blue for
cold and red for hot.
Connect the water inlet hoses to taps
with a 3/4” thread.
If only a cold water supply is
available, connect the two hoses to a
cold water outlet by means of a «Y»
connection piece.
