3. INSTALLATION
3.1 Water connection
Inlet water quality
The quality of the water used in all the cleaning stages is important to have good results.
The water used in each stage must be compatible with:
The material of which the machine is made.
The chemicals used in the process.
Process requirements for the various stages of the process.
In order to achieve good cleaning results, the machine needs to operate with soft water. Hard
water results in the build-up of calcium deposits on the load and in the machine.
If the mains water hardness level is more than 7 °fH (0.7 mmol/l or 4°dH), a water softening
system should be provided on site.
Note: It is the user’s responsibility to supply the machine with suitable water.
ATTENTION
Water from the wash cabinet must not be consumed.
The lab washer must be connected to the water supply in strict accordance with current local
and national water authority regulations.
The water used must be drinking-water quality. If the water supply has a high iron content
there is a danger of corrosion occurring on items being cleaned in the lab washer, as well as
the appliance itself. If the chloride content of the water exceeds 100 mg/l the risk of corrosion
to items being cleaned in the lab washer will be further increased.
In certain regions (e.g., mountainous areas) the water composition may cause precipitates to
form, requiring the use of softened water in the steam condenser.
The lab washer is supplied as standard for connection to cold water (blue coded) and hot
water up to max. 140 °F (red coded). Connect the inlet hoses to the water valves for cold and
hot water.
If there is no hot water supply available, the inlet hose coded red must also be connected to
the cold water supply.
The minimum flow pressure for cold water, hot water and for DI water connection is 14.5
psi (100 kPa).
Recommended flow pressure for cold and hot water connections is ≥ 29 PSI pressure and
for DI water connection ≥ 29 PSI pressure, to avoid excessively long water intake times.
The maximum permissible static water pressure is 116 psi (800 kPa) pressure.
If it is below 14.5 psi (100 kPa) dynamic pressure, you will need to install a pressure
increase pump. If the pressure is higher than 145 psi (1000 kPa) a pressure reducer
must be installed.
If the water pressure does not fall into the stated range, contact Miele Service or an
authorized and trained service technician for advice.
A water valve with a ¾" threaded union must be provided on site. It should be easily
accessible so that the water supply can be turned off when the machine is not in use.

Drainage must be done following international rules.
The manufacturer cannot be held responsible if an inaccurate if
inaccurate machine use causes pollution.
If the drain system is clogged take great care when processing the water
and avoid contact with hands, eyes, etc. In the case of contact rinse the
parts concerned with plenty of water.
When the machine is connected to an exhaust ventilation system, the
drain hose should be positioned outside the building, protected from any
animal access, and make sure that it not causes any hazard.

Drain cooling
The machine is equipped by a system of drain cooling, which can be useful in order to reduce
the temperature from the standard temperature of 200° to 140°F (93° to 60°C).
3.7 Ambient ventilation requirements
During normal operation, the machine warms up itself dispersing heat and humidity.
Therefore, in order to guarantee a comfortable environment with good temperature and
humidity for the user, it is necessary to prepare an air conditioning or air circulation system
capable to balance the emissions reported in the installation plan.
Only when toxic detergents are used and/or it is expected that it is not possible to guarantee
acceptable levels of temperature and humidity in the installation environment, the air exhaust
of the equipment must be connected to a venting system.
The air that is expelled from the chamber must not be re-circulated so as to protect the user
from any undesired emissions produced by the machine or by the chemical products present
within the work area.

The machine connections are shown in detail on the
installation plan and electrical wiring diagram.
