Designated use

The indoor air laundry dryers WT 230/240/250/280 are intended for air dehumidification and laundry drying in closed rooms.

The indoor air laundry dryers are designed exclusively for use at atmospheric pressure. Operating the dehumidifiers within the limits of designated use also involves observing the specified operating conditions (refer to page 36). Any use of the device going beyond the designated use specified above is considered contrary to its designated use.

Misuse is concerned if the WT indoor air laundry dryer is used for purposes not included in designated use. In these cases, the manufacturer does not assume any liability for personal and material damage.

Safety

Safety devices

The WT series indoor air laundry dryers were subjected to thorough safety testing.
Improper operation or misuse will cause danger to

• the operator,
•  the machine and other material properties of the user,
• efficient operation of the machine.

All persons involved in the installation, commissioning, operation, maintenance, and servicing of the devices must

• be properly qualified,
• closely observe the instructions set out in this manual.

Hazards from accessories

Wastewater hoses, power cables, and air filters must be properly installed and must not disable the protection devices of the indoor air laundry dryers. The operating elements must always be accessible.

Authorized operator

Indoor air laundry dryers may only be operated by persons commissioned and instructed by the user. In the working area, the operator is responsible for third parties. For all activities on the device, the responsibilities must be clearly defined and observed. Unclear competencies are a safety risk.

User

The user must

• make the instruction manual accessible to the operator,
• and make sure that the operator has read and understood the instruction manual.

Safety instructions

The devices must not be used under the following conditions:

•  In rooms with potentially explosive atmospheres.
• in rooms with aggressive atmospheres, e.g. ammonia, wood acids.
• In rooms with water with a pH value below 7.0 or above 7.4.
  In case of low ph values, there is a risk of corrosion on all metals and risk of damage to mortar-containing materials (joints). Higher pH values cause mucous membrane irritations and increased lime deposits.
• In rooms with salt or liquids with a salt content > 1%.
• In most areas of indoor swimming pools.
• in rooms with ozone-treated air.
• in rooms with high solvent concentration.
• in rooms with extreme dust load.
• The laundry dryer must always be stored in a dry environment.

Please note that excessive additional air movements in the room may impair the function of the laundry dryer because they could disturb the airflow of the laundry dryer.
In addition, the following must be observed when using the indoor air laundry dryer:

• Only trained electrical professionals (e.g. electricians) are permitted to work on electrical components, especially when connecting to the electric circuit.
• The device must always be transported by two people, or suitable lifting gear must be used.
• Original spare parts or spare parts approved by the manufacturer shall exclusively be used.

Model

The indoor air laundry dryer is available in two models and various sizes. The two models can be identified by their item numbers (on the identification plate) and differ as follows:

Construction

Fig. 1: AERIAL WT series – overview

How long the indoor air laundry dryer must be used to dry a room or a certain amount of laundry or to reach a certain humidity depends on the ambient conditions in the room
in which the device is installed.

Transport and installation

Transport

DANGER	Danger to life due to electric shock Touching live parts can lead to death. Before moving the indoor air laundry dryer, always switch it off at the on/off switch and, depending on the model, pull the mains plug out of the socket or have it disconnected from the electrical circuit by a trained electrical professional (e.g. electrician).
WARNING	Cutting and crushing hazard When the air filter has been removed cutting injuries from the sharp edges of the heat exchanger may occur. Two people are needed to carry the indoor air laundry dryer, or suitable lifting gear must be used for transport. Wear protective gloves when changing the air filter. Do not reach into the inlet screen.
WARNING	Danger of injury The indoor air laundry dryer is heavy. Loss of stability or uncontrolled movements may cause serious injuries and material damage. Lift the device with a colleague and use suitable lifting and transport equipment. In the case of wall mounting use suitable holders and fastening elements according to the weight.
CAUTION	Material damage Pulling the power cable may damage the cable. Before transporting the indoor air laundry dryer, depending on the model, always pull out the mains plug or have all electrical connections disconnected from the electrical circuit by a trained electrical professional (e.g. electrician).

1. Transport the indoor air laundry dryer to the place of installation using suitable lifting gear or have it carried by two persons.
2. Remove the packaging material completely and dispose of it according to the local regulations.

CAUTION

The danger of damage to the device Insufficient air circulation can result in damage to the device and inefficient operation. Install the indoor air laundry dryer in such a way that free air circulation is ensured. Ensure that the air filter and air outlet are not covered. The free space in front of the front panel must be at least 0.5 meters.

Wall mounting

Fig. 3: Wall rail

The scope of delivery includes one wall rail (Fig. 3) and suitable bolts and sound insulation anchors.

WARNING

The danger of loss of stability or dropping from the wall The indoor air laundry dryer is heavy. A fall or uncontrolled movements may cause serious injuries and material damage. In case of wall mounting use suitable provided rail and fastening elements suitable for the weight.

1. Attach the wall rail straightly aligned (use spirit level!) and securely to a suitable wall using four bolts.
   Above the rail, a clearance of about 30 cm to the ceiling is required to enable mounting of the indoor air laundry dryer in the wall rail without problems.
2. Lift the indoor air laundry dryer from the top into the wall rail in such a way that the mounting bar on the rear side (page 34,34 Fig 1, item 4) engages in the wall rail.
   

   CAUTION

   Damage to the device The indoor air laundry dryer must be aligned along all axes. Check the position of the indoor air laundry dryer using a spirit level.

3. Fix the indoor air laundry dryer using the two lateral fixing screws on the wall rail.
