Transporting the tumble dryer

The danger of injury to people and damage to property caused by moving the appliance incorrectly. If the tumble dryer tips over, there is a danger of injury to people and damage to property. Ensure that the tumble dryer is stable during transportation.

• If the tumble dryer is being transported horizontally, it must only be tipped onto its left or right side.
• If the tumble dryer is being transported upright and you are using a handcart or trolley, you must only transport it with its left or right side resting on the handcart or trolley.

Transporting the tumble dryer to its installation site
Make sure the fixings at the back of the lid are secure. Otherwise, there is a danger of the lid being pulled off when carrying the appliance. Before carrying the appliance, check that the lid is secure where it protrudes at the back of the appliance.

• Carry the tumble dryer by the front feet and by the lid where it protrudes at the back of the appliance.

Installation

Leveling the dryer

The appliance must not be installed behind a lockable door, a sliding door or a door with a hinge on the opposite side to that of the tumble dyer, in such a way that a full opening of the tumble dryer door is restricted.

To ensure proper operation, the tumble dryer must stand perfectly level. The screw feet on the tumble dryer can be adjusted to compensate for unevenness in the floor.

• Turn the screw feet by hand or with a flat open spanner.

Downtime after installation

Damage to the tumble dryer by switching it on too soon. This can damage the heat pump. After setting up the tumble dryer, wait for at least one hour before switching it on.

Ventilation
The cool air intake at the front of the tumble dryer must not be blocked or covered. This would hinder a sufficient intake of cool air for the heat exchanger.

Do not block the gap between the bottom of the tumble dryer and the floor with plinth facings, deep pile carpet, etc. This would hinder a sufficient flow of air to the tumble dryer. Adequate ventilation has to be provided to avoid the backflow of gases into the room from appliances burning other fuels, including open fires.

Air that is taken in to cool the heat exchanger is then blown back out of the dryer and warms up the air in the room. Ensure sufficient ventilation of the room, e.g. by opening a window. The drying time will otherwise take longer (higher energy requirement).

Before moving the tumble dryer again (e.g. when moving house)
After each use, a small quantity of condensed water will collect in the area of the pump. This water can run out if the tumble dryer is tipped up when it is being moved. Recommendation: Run the Warm air program for approximately 1 minute without a load before moving the tumble dryer. Any remaining condensed water will then be fed into the condensed water container, which can then be emptied or can drain out through the drain hose.

Additional installation requirements

Suitable for pushing under a worktop
This tumble dryer is suitable for pushing under a worktop.

Appliance defect due to a build-up of heat. Make sure there is adequate room for warm air from the dryer to be directed away.

• The appliance lid cannot be removed.
• The electrical socket must be located in an accessible position near the appliance.
• Drying durations may increase slightly.

Optional Accessories

Washer-dryer stack
The tumble dryer can also be combined with a Miele washing machine in a washer-dryer stack. The appropriate Miele washer-dryer stacking kit is required.

Plinth
The tumble dryer can be fitted with a plinth with a drawer (please note the plinth may not be available in all countries).

Externally draining condensed water

Notes
When drying is in progress, condensed water is pumped into the condensed water container through the drain hose which is located at the back of the dryer.

The condensed water can also be drained away via the drain hose. The condensed water container will then not need to be emptied.

• Hose length: 1.49 m
• Maximum delivery head: 1.00 m
• Maximum drain hose length: 4.00 m

Drainage accessories

• Supplied: adapter (b), hose clip (c), hose holder (e);
• Available to purchase: “Non-return valve” kit for connection to an external water connection. Non-return valve (d), hose extension (a) and hose clips (c) are supplied with the kit.

Installation conditions requiring a non-return valve
The danger of condensed water backflow. Water could flow back into the tumble dryer or be drawn into it. Backflow water could damage the tumble dryer and also the room in which it is located. The non-return valve should be used if the end of the hose is immersed in water, or if other water connections are installed.

• Maximum delivery head with non-return valve fitted: 1.00 m
• Installation conditions requiring the fitting of a non-return valve:
  • Drainage into a laundry tub or floor gully where the end of the hose is immersed in water.
  • Connection to a sink drain outlet.
  • Connection to a drainage system already in use by another appliance, e. g. a dishwasher or washing machine.

If the non-return valve is incorrectly fitted the appliance will not drain. The non-return valve has to be fitted with the arrow on it pointing in the direction of flow.

Arranging the drain hose

• Damage to the drain hose through incorrect handling.
• The drain hose can suffer damage and leak.
• Do not pull on the drain hose and do not stretch it or allow it to become kinked.

There will be a small amount of residual water left in the drain hose. Have a container ready to collect this.

• Pull the drain hose off its connection (light arrow).
• Pull the hose out of the holders (dark arrows) and unwind it.
• Allow any residual water to run into a container.

Examples
Drainage into a laundry tub or floor gully

• Use the hose holder to secure the drain hose.

Risk of water damage.

• Should the end of the hose come loose, overflowing water can cause damage.
• Secure the drain hose carefully (e.g., by tying it) to make sure it cannot slip.

The non-return valve can be fitted in the end of the hose. Direct connection to a sink drain outlet

Use the hose holder, the hose clips and the non-return valve (available to purchase).

Electrical connection

The tumble dryer is supplied with a mains cable with molded plug ready for connection to a socket.

The socket should be easily accessible after the tumble dryer has been installed. If the socket is not easily accessible, ensure that a suitable means of disconnection is provided on the installation side for each pole.

• Risk of fire from overheating.
• Connecting the tumble dryer to a multi-socket plug adapter or to an extension lead can overload the cable.
• For safety reasons, do not use an extension cable or multi-socket adapter.

All electrical work must be carried out by a suitably qualified and competent person in strict accordance with national and local safety regulations. For safety reasons, we recommend using a suitable residual current device (RCD) in the relevant electrical installation for connecting the tumble dryer.

If the mains connection cable is damaged, it must only be replaced with a specific mains connection cable of the same type (available from Miele). For safety reasons, such replacement may only be carried out by a suitably qualified and competent electrician or a Miele authorised service technician, in order to avoid a hazard. The data plate indicates the nominal power consumption and the connection data. Compare this information with the data of the on-site electrical connection.

If in any doubt, consult a qualified electrician. Temporary or permanent operation with a self-sufficient or non-mains synchronous energy supply system
(e.g. isolated networks, backup systems) is possible. A requirement for the operation is that the energy supply system complies with all current local and national requirements that apply to stand-alone, solar, and/or battery systems. The protective measures provided in the domestic installation and in this Miele product must also be assured in their function and operation in isolated operation or in non-mains synchronous operation, or replaced with equivalent measures in the installation.
