2.1 Installation as a Free-Standing Unit

To ensure fault-free operation, the appliance should be installed perfectly level.

Any unevenness in the floor can be compensated for by adjusting the

2.2 Installation under a Continuous Worktop

2.2.1 Models with Half Closed Base Plate (Initial Production Models)

2.2.2 Models with Fully Closed Base Plate

screw-in feet at all four corners.

To correctly install the appliance under a continuous worktop, a “building under” kit is required. Fitting instructions, Part no. 1508041, are included with the kit.

Building a machine under can slightly increase drying times but does not, though, affect energy consumption.

These models can be built-in under certain conditions. It is essential to ensure that sufficient air can be taken in at the

rear of the machine.

They may be installed next to a washing machine. However, if the washing machine has a décor panel front then the service panel sealing strip should not be fitted so that air intake can also take place in this area.

If the dryer is built-in alone, gaps for air intake must total at least 100 cm2.

The approx. 10mm gap along the machine’s lower front edge should never be reduced or blocked by deep pile carpets, skirting strips or tiles, etc.

1. Unscrew the clip from the outlet connection and remove the rubber seal (refer to Figure 2-1 – Draining the Condensate to the Rear).

2. Fit the drain hose supplied (not with T 368 C) or other suitable hose and affix it with the clip (refer to Section 1.12.1 Rear Drainage).

4.1 Electronic Residual Moisture Detection Unit EF 102

As with most other Miele household dryers, the drying stages of this appliance are electronically monitored and controlled. As can be seen in the block diagram, the desired level of dryness (i.e. the desired residual moisture level) set at the timer is passed via the printed circuit and the pulse generator stage to the residual moisture comparator.

The 4 minute time stage prevents the timer from advancing to the next stage too early after switching on if the level switch has not reset.

The stainless-steel drum body and its internal ribs serve as sensor contacts to monitor the residual moisture content of the load. Once the required dryness level has been detected, a control stage lasting 1 minute begins. The timer will not advance to the next stage of the program unless the correct moisture level is maintained throughout this control stage.

The level switch closes when the condensate collector becomes too full. This switches a relay which then sends step impulses to the timer, until it

has advanced to the “Stop” position, and also switches an LED indicator

on.

Figure 4-1: Electronic Residual Moisture Detection Unit EF 102

T300 Series Clothes Dryer (Condenser)

Technical Information

4.2 Electronic Residual Moisture Detection Unit EF 202

A low voltage signal (approx. 33 V) is passed from the electronic unit transformer to the timer. From there, it is returned, via the timer contacts, to the electronic unit.

This signal then charges the capacitor C1, which is in turn discharged, via the sensors, by the damp (conductive) load in the drum.

During the drying process, the load becomes less conductive and the capacitor C1 is charged until the desired value (Udesired) of the first residual moisture stage is reached. At this point, charging of capacitor C2 begins. After a further minute has elapsed, this capacitor is also fully charged, providing that no discharge has occurred due to damp items of laundry coming into contact with the sensors.

4.2.1 Level Control

If, either due to a fault or operator error, the condensed water container is too full, then the level switch is activated.

The level switch sends a DC signal to the second residual moisture stage. After approx. 3.5 seconds, this switches both the stepping relay on, which advances the timer to the “Cool Air” cycle, and also the LED warning light. The transistor switching stage retains this state until the machine is switched off.
