Using Your Tumble-Drier(滚筒烘干式洗衣机) Controls Timer(计时器)Control To operate the dri

Using Your Tumble-Drier(滚筒烘干式洗衣机)

Controls Timer(计时器)Control

To operate the drier, close the door and turn the timer control to the required. The timer can be set to any time up to 120 minutes and can be reset at any time as required to increased or reduced the time to dry, but in doing so the timer knob (旋钮) must only be turned clockwise. Turning the timer backwards will cause damage and it must therefore be turned forwards even to reach the "off" position. The timer is electrically driven and will therefore only advance when there is power supplied to the drier and the drier door is closed. The time indicated on the timer includes approximately 10 minutes of tumble of tumble with the heat off. Note that the driver (主动轮) should never be turned off leaving the clothes in the drum without first completing the heat-off cool-down period.

Heat Control

There are two levels of heat which may be selected by setting the control to (low) or(high). Many materials may be dried using high but pay particular attention to setting the control to low heat for the materials mentioned under "Drying Times" below.

Automatic Door Switch

The drier will stop when the door is opened and will restart when the door is closed, allowing items to be added or taken from the drier without the need to reset the controls.

Before Tumbling

Never over spin easy-care fabrics in your automatic washing machine or spin-drier, and always follow the washing instructions given on the Care Label attached to the garment. Easy-care and synthetic fabrics dry quickly in a tumble-drier and many of them will not need ironing if they are dried in small loads. It is important to remove them from the tumble-drier as soon as the drier stops after the cool down period to avoid causing unnecessary creasing(皱褶).

Fabric Conditioner

Conditioner added to the final rinse(漂洗)in your washing machine will give even more softness to all fabrics and is invaluable for reducing the static electricity which causes fabrics containing synthetic fibers to cling and attract dirt.

After Tumbling

All clothes lose lint(碎线头)as they wear. When clothes are hung on a washing line the lint is blown away by wind. In a tumble-drier it is collected in the lint filter. The door incorporates a mesh (网眼) lint filter which is removed by lifting out vertically. It is essential to remove the lint from the filter every time the drier is used. Failure to do this will result in poor drying performance and may lead to mechanical or electrical breakdown.

Making up Loads

Maximum loads

Cottons and linens 3kg (6.5 lb) dry weight

Synthetic fabrics 1kg (2 lb) for minimum creasing or

Cotton and viscose(黏胶织物)with 2 kg if creasing is unimportant

Special finishes

Clothes should be sorted into loads of similar fabrics before drying. Towels and other cotton items which do not need ironing can be fully dried and these will be ready to store or wear as soon as they are taken from the drier. Cotton which needs ironing can be dried to a suitable dampness by reducing times suggested by approximately one quarter. Heavy fabrics should be dried separately from lightweight fabrics as a general role. Very bulky large items which do not tumble should not be dried in a tumble-drier.

Drying Times

These will depend on the size of the load, the type of fabric and the wetness of the load. It is not therefore possible to give exact drying times to cover all the variables, but experience will enable you to set the time for fully drying or damp drying as required.

This passage gives instructions in using the tumble-drier.
