Frequently Asked Questions (FAQ)

Q: Can the heat-pump dryer be used for residential purposes?
A: No, the heat-pump dryer is intended only for commercial use in indoor environments.
Q: How often should the fluff filter be cleaned?
A: The fluff filter in the air intake vent should be cleaned regularly by hand to maintain proper airflow.
Q: What should be done if there is a risk of increased noise during operation?
A: In case of increased noise, have the installation site inspected and seek advice from a professional to address any potential issues.

Installation plan Commercial heat-pump dryer

Installation requirements

Risk of injury or damage to property due to improper installation.
Incorrect installation of the tumble dryer can lead to personal injury or damage to property.
The tumble dryer must only be installed and commissioned by Miele Customer Service Department or an authorised dealer.
The tumble dryer must be installed in accordance with all relevant regulations and standards.
The dryer must only be operated in a room that has sufficient ventilation and which is frost-free.
The tumble dryer must not be installed behind a closeable door or a sliding door. The maximum opening angle of the tumble dryer door must not be limited by objects or doors. It must be possible to fully open the tumble dryer door at any time.

Electrical connection

The electrical connection must be established by a qualified electrician.
The electrical connection may only be made to an electrical system provided in accordance with all appropriate local and national legislation, regulations and guidelines. Please also observe the regulations set out by your insurance provider and energy supplier, accident prevention regulations, as well as recognised codes of practice.
Reliable and safe operation of this tumble dryer is only ensured if it
has been connected to the mains electricity supply.
The required supply voltage, power rating and fuse rating can be found on the data plate on the tumble dryer. Ensure that the supply voltage matches the voltage quoted on the data plate before establishing the electrical connection to the tumble dryer.
Connection to a supply voltage other than the one quoted on the data plate can damage the tumble dryer if the voltage is too high.
If more than one voltage is specified on the data plate, the tumble
dryer can be converted for connection to the relevant input voltage. This conversion must be performed by the Miele Customer Service Department or by an authorised dealer. During the conversion, the wiring instructions given on the wiring diagram must be followed.
Tip: We recommend connecting the tumble dryer to the power supply via a plug and socket so that it is easier to conduct electrical safety checks (e.g. during maintenance or repair work).
It is recommended the tumble dryer is connected with a suitable plug and socket in accordance with IEC 60309-1, however if the installation requires a hard-wired connection, an all-pole means of isolation must be provided on site. Switches with a minimum contact gap greater than 3 mm are suitable disconnectors. These include circuit breakers (MCB), fuses and contactors (VDE 0660) (IEC/EN 60947)
If the mains supply cannot be permanently disconnected, the isolation device (including plug and socket) must be safeguarded against being switched on either unintentionally or without authorisation.
The tumble dryer must not be connected to devices such as timers which would switch it off automatically.
If it is necessary to install a residual current device (RCD) in accordance with local regulations, a residual current device type B (sensitive to universal current) must be used.
Loud noises and risk of damage due to incorrect phase connection on heat-pump dryers.
An incorrect phase position causes a lot of noise in tumble dryers with heat pumps and can cause damage to the compressor.
When connecting a heat-pump dryer to the power connection, en-sure the correct phase position according to the wiring diagram.

Installation of variants with heat pumps

General operating conditions

This heat-pump dryer is intended only for use in a commercial environment and must only be operated indoors.
Ambient temperature for optimum heat-pump operation: +10 °C to +40 °C
The ambient temperature for the heat-pump dryer must be at least 10 °C.
At lower ambient temperatures, there is a risk of ice forming on the lower heat exchanger. This can also result in unexpected condensate formation.
Depending on the nature of the installation site, sound emissions and vibrations may occur.
Tip: Have the installation site inspected and seek the advice of a professional in instances where increased noise may cause a nuisance.

Transport

The tumble dryer and the heat pump must not be transported without transport pallets.
Suitable transport aids must always be used during transportation.
Tilting the heat pump by more than 30° should be avoided if at all possible.
After the heat pump has been transported, it should be left to stand for approximately one hour before commissioning. If the heat pump is subjected to especially strong vibrations or is tilted by more than 30°, it should be left to stand for up to 24 hours.
At the next installation site, the tumble dryer and the heat pump must be lifted off the transport pallet using suitable lifting gear.
If the heat-pump unit is tilted up to a maximum of 30° during transportation, it must be left to stand for at least one hour after it has been installed before the heat-pump dryer can be operated.
After transportation and installation, downtime of at least one hour is required before connecting the tumble dryer to the electricity supply.
Insufficient downtime before commissioning can damage the heat pump.

Air intake vent

Air intake for the condenser is via an air intake vent at the front of the dryer. Air is taken from the room in which the dryer is installed.
A fluff filter is located in the air intake vent in the dryer. This must be regularly cleaned by hand.
The air intake vent must be kept clear. It must not be covered.

Air outlet vent

Because the heat-pump dryer operates with a closed air circuit, separate exhaust ducting is not required.
The warm air expelled from the machine as a result of cooling down the heat-exchanger warms the room air. It is essential to ensure the room has adequate ventilation, e.g. by providing ventilation openings that cannot be closed whilst the machine is in use. Insufficient ventilation in the room increases the time required for drying, which in turn will increase the amount of energy required for the drying process.
The ventilation openings must, on no account, be closed or blocked by objects.

Condensate drainage point

The heat pump in this tumble dryer operates according to the principle of condensation. A separate, vented floor drain must be provided at the installation site for condensate produced during the drying process.
The condensate drainage point is located at the back of the heat-pump dryer. Condensate can be fed via a downwards pointing pipe to the floor drain. It must be ensured that condensate cannot flow back into the dryer.
Risk of electric shock and injury due to using the tumble dryer without the complete casing.
If the casing is dismantled, it is possible to come into contact with live or rotating machine parts.
Once the tumble dryer has been installed, replace all the casing parts that were removed.
