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.

3.6 Connecting the drain hose
The drain hose connection should be checked carefully.
The machine is equipped with a drain hose with a diameter indicated on the
installation plan.
The choice of materials relating to the ventilation circuit for drainage operations must
take into account the same requirements as for piping that comes into direct contact with drain fluids; it must be taken into consideration that these may give off harmful (corrosive, toxic, etc.) vapors that may involve the output/input point of the duct.
CAUTION
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.
The drain hose is connected to the sewer network in the following manner:
Identify the drain pipe and relative fittings, and assemble them.
Make sure the seal gasket is installed correctly.
Identify the drain manifold and connect the hose via the union and ring nut. Tighten
the ring nut firmly.
Insert the drain hose and clamp it in place.
Insert the other end of the hose into the drain unit, installing it properly and locking it
in position.
It is necessary to follow these instructions for drain connection:
Drain hose must be connected by using a clamp.
Drain hose must not present angles or irregular curving in its course.
Drain point must be placed at the same height of the machine drain point or on the
floor.
INSTALLATION
Carefully follow these instructions as a wrong drain connection can cause the block of machine.
The diameter of main drain must be as indicated on the installation plant.
Avoid drain pipe extension.
ATTENTION
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.
REV.0.04 _COD.610078_A4 Page 19
INSTALLATION
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.

REV.0.04 _COD.610078_A4 Page 23
USING THE MACHINE
5.4 Preparation
Make sure that the items can be cleaned inside the machine and verify the
compatibility with the cleaning agents used during the cycles.
Place the items to be washed inside the machine and position them carefully on the
holder and in the rack.
Items should not overlap.
Items should be positioned so that liquids can flow out easily.
Tall or heavy items should be placed towards the middle of the basket if possible to
facilitate washing.
Make sure that nothing is blocking the arms and that they turn freely.
Place the load uniformly in the basket.
The mobile units, baskets, modules and inserts that hold the load must be used only
as intended.
Empty any containers or utensils before loading them.
Take apart any items which can be dismantled according to the manufacturer's
instructions and process the individual parts separately from each other.
Do not place items to be cleaned inside other pieces where they may be concealed.
Do not place items so close together that cleaning is hampered.
Arrange the load so that water can access all surfaces.
Only clean small items and micro components in special inserts, mesh trays with lids
or mesh inserts.
Plastic items must be thermally stable.
ATTENTION
The maximum load for each cycle is 44lbs (20 kg) (basket included).
Never use the machine without basket.
Before starting to use the machine, please make sure that all the routine checks have been made. Verify the wash arms and their rotation.
ATTENTION
Never empty any solid waste into the machine.
This will block the drain system with pump and destroy the machine.
Noncompliance, even in part, of the rule here indicated, can cause dangerous leakage of water from the door.

These could be hazardous to human health and to the environment if disposed of with your domestic waste or if handled incorrectly. Please do not, therefore, dispose of your old appliance with your household waste.
Please dispose of it at your local community waste collection / recycling center for electrical and electronic appliances, or contact your dealer or Miele for advice.
