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.

2 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 property 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

Waste water 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 to 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,
■ 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 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 moist 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 air flow 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.

7 Maintenance and care

Maintenance work

Cleaning intervals depend largely on the operating conditions. Therefore check your indoor air laundry dryer after every drying process.

In order to guarantee trouble-free functioning of the indoor air laundry dryer it must be cleaned at regular intervals, and in particular the air filter must be checked. Proceed as follows:

■ Remove and clean the air filter, replace it if necessary (see page 34, Fig. 1, item 1).

Danger of injury by electric shock and risk of material damage

The indoor air laundry dryer may only be repaired by trained specialised staff. Within the warranty period, any work on the dehumidifier shall only be carried out by the manufacturer or persons commissioned by the manufacturer. Any work carried out by unauthorized persons shall lead to the forfeiture of all warranty claims!

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.

■ Visual inspection: drain pipe and connected hose.
■ Clean casing on the outside with a moist cloth.
■ Insert a new or clean filter. Only use an original filter to ensure that the indoor air laundry dryer works properly.

Faults

Problem	Possible cause	Remedial action
Low or no dehumidifying performance	The air filter is severely soiled. Air intake of indoor air laundry dryer is too low.	Clean the filter (page 34, Fig.1, item 1) or insert a new one.Check the filter before each use.Use only original air filters, since unsuitable air filters will impair the air flow.
Device is out of operation. Fan and compressor do not work.	Indoor air laundry dryer switched off	Switch the indoor air laundry dryer on (s. page 34, Fig.1, item 6).
	Indoor air laundry dryer without power supply	Have the power cable, the plug connection, the plug socket and the building fusing checked by an expert.
Unexpectedly long drying time	The indoor air laundry dryer is not correctly dimensioned for the application.	The air exchange rate, the number of persons in the room, the quantity of wet clothes and any open water surfaces are decisive for the humidity load of the room. Ask your specialised dealer to calculate the capacity required for your application.
	There is a lot of humidity in the walls, the floor etc.	In this case the indoor air laundry dryer will need some time to remove the water and achieve an acceptable value in the room.

9 Decommissioning, storage and disposal

Decommissioning

If you do not need the indoor air laundry dryer for a longer period of time you can shut it down for some time. To do so proceed as follows:
