Notes on supply connections:

Cold, hot and demineralised water, high-pressure steam, condensate and compressed air supplies
can be routed through the ceiling or, alternatively, through the floor. A combination of the two is not
possible. Connection of waste water and floor tray on dump valve (AV) models is only possible
through floor. Cooling circuit feed and return pipes for steam condenser (optional) through ceiling only.
Easily accessible central stopcock and main switch recommended.

Preparatory work

Core-drilled access hole in floor according to drawings or template, Mat. no. 5488570, available from
Spares. Further access holes required for tubing and cabling if chemical product supply line access is
through the floor.

Recommended core-drilling diameters: Waste water connections 100 mm Ø
Chemical supply connections 230 x 170 mm (W x D)

Use directly abutting templates for run of machines. Template size corresponds to diaphragm wall cut­out which is slightly larger than machines to allow for 5 mm gap between machines and 3 mm gap
between machine and diaphragm wall. These gaps are sealed on site using a suitable sealant.

Waste water connection:

Drain manifold (minimum diameter DN 100) to be installed under floor and fitted with odour trap on
site. Connections to manifold (DN 50) to be fitted vertically to extend to specified height above floor at
predetermined points. Hose sleeve of drain pipe for drip tray drain should end 35 mm above finished
floor level; hose sleeve of drain pipe for machine drainage should end at finished floor level. Additional
removable stub-out with slip joint to 200 mm above finished floor required for machine drainage. Stub­out extensions to be cut to size and removed to facilitate machine handling. Stub-out extension fitted
after washer-disinfector has been positioned in the plinth/floor tray. If plinth/floor tray is planned later,
use pipe caps to close pipes.

Electrical connection:

Electrical supply lines can be routed through floor or ceiling. Min. cable length of 1500 mm above
finished floor surface required with access through floor. Min. cable length of 4000 mm from top edge
of top-box panelling required with access through ceiling.

Standard installation, chemical supply connections:

Install supply lines vertically from ceiling, adjust and locate. All pipework, including insulation, fittings
and valves with taps should be located within the designated area (520 mm × 130 mm). No part of the
installation should extend beyond this area.

Hot, cold and demineralised water lines, high-pressure steam and condensate lines end with a ¾" ext.
thread and compressed air lines with a ½" int. thread 2,224 mm above finished floor.

Miele recommends the installation of a check valve directly below the condensate trap in order to
prevent water hammer.

If washer-disinfector is installed with a steam condenser, install cooling circuit feed and return pipes
vertically from ceiling and secure. Both are connected to the steam condenser with a flexible hose (int.
diameter 14 mm) which is to be provided on site. In the absence of cooling circuit, connect steam
condenser to cold water.

Alternative installation, chemical supply connections:

Route supply lines through floor to approx. 200 mm above finished floor and secure. Supply lines are
shortened after installation of plinth/floor tray. If plinth/floor tray is planned later, use pipe caps to close
pipes. Install floor tray horizontally using spirit level. Stopcocks in the chemical supply lines are
installed after the floor tray has been fitted. Install stopcocks for cold, hot and demineralised water,
high-pressure steam, condensate and compressed air according to drawings. Pipework and
stopcocks should rise by no more than 90 mm above finished floor and should on no account rise
above plinth/floor tray.
If washer-disinfector is installed with a steam condenser, install cooling circuit feed and return pipes
vertically from ceiling and secure. Both are connected to the steam condenser with a flexible hose (int.
diameter 14 mm) which is to be provided on site. In the absence of cooling circuit, connect steam
condenser to cold water.

Waste air installation:

In order to expel vapours, air throughput of 350 m³/h for each machine is required on the unclean side
of the operation.

Connection to external vent system with or without steam condenser:

Connection of the washer-disinfector to an external vent system is via an extractor canopy. An air gap
of at least 80 mm should be provided. A suitable vent canopy is provided with the washer-disinfector.
The use of a two-stage fan is recommended (cf. Technical Data Sheet 'Electrical connection' on fan
control). Laying a flexible duct to directly above the machine facilitates installation.

Venting to atmosphere:

The canopy provided should not be fitted if the washer-disinfector is vented directly to atmosphere.
Never merge vent ducts from multiple washer-disinfectors! Vent each machine separately!
