Safety

Intended use and conditions of use
The dehumidifier is used to remove humidity from the air where there is atmospheric pressure in closed indoor rooms, such as basements, garages, or warehouses. The dehumidifier must only be set up, used, and stored in rooms larger than 4 m 2. The dehumidifier must only be used in compliance with the Technical Data (see the last page). Persons with physical, sensory, or mental restrictions and children are not permitted to use the dehumidifier. Every user must have read and understood the operating instructions.

Foreseeable misuse
The dehumidifier must not be used:

• In rooms with potentially explosive atmospheres.
• In rooms with an aggressive atmosphere (e.g. caused by chemicals).
• In rooms with water with a pH value below 7.0 or above 7.4.
• In rooms with salt or liquids with a salt content > 1 %, e.g. brine baths.
• In wet areas of indoor swimming pools.
• In rooms with ozone-treated air, high solvent concentrations, or high dust pollution.

General safety information
WARNING! Risk of explosion, burns, and poisoning from refrigerants!
The appliance contains an odorless, flammable refrigerant which, if handled incorrectly, could result in explosions and fire as well as injuries and burns.
The refrigerant circuit is pressurized.

•  Do not use any objects to accelerate the thawing process.
• Do not store the dehumidifier in rooms with permanent sources of ignition, such as open flames, operational gas appliances, or electric heaters.
• Do not drill open or ignite dehumidifiers.
• Only operate the appliance in an adequately ventilated room larger than 4 m².
• Any work to the refrigerant circuit must be performed by the manufacturer or the manufacturer’s authorized technical personnel. Before working on the refrigerant circuit, it must be depressurized using the designated mechanisms.
• Observe the national regulations for gas installations.
• Do not dump refrigerants or dispose of them as household waste.
• Avoid coming into contact with the refrigerant.

WARNING! Electrocution!
Working on live components or water on live components can cause life- threatening electrocution.

• Avoid contact between water and live components.
• Always switch off and unplug the dehumidifier and drain away any water before moving it to another location.
• Always empty the basin before moving it to another location.
• Only allow the manufacturer or an authorized personnel to carry out work on electric components.

Unpacking

Procedure

1. Check that the package contents are complete. Contact your stockist in the event of damage or missing contents.
2. Remove the packaging and dispose of it in accordance with local regulations.

Stacking appliances

Two appliances from this series can be stacked on top of each other for transport and storage.

Warning! Crushing as a result of tipping or instability!

• Do not stack more than two dehumidifiers on top of each other. Make sure that the feet of the top appliance is in the notches of the bottom appliance.
• Secure the dehumidifiers to prevent them from tipping over or falling, e.g. using tension belts.

Procedure

• Place the feet of the top appliance in the appropriate notches of the bottom appliance.
• Attach a suitable safeguard, e.g. tension belts, to the attachment points for straps to secure the top appliance to the bottom appliance and stop it from falling off. Stack a maximum of two appliances.

Transport and connection

Transport
WARNING! Crushing as a result of instability!

• Transport the dehumidifier in an upright position and secure it so that it cannot tip over or slip.
• Position the dehumidifier on a stable, even surface.

WARNING! Crushing or cutting from reaching into the grille of the air filter!

• Use the handles to transport the dehumidifier.
• Do not reach into the air filter.

CAUTION! Crushing or ergonomic damage when transporting the dehumidifier!

• Use the handles to transport the dehumidifier.
• The dehumidifier must be transported by two people.

Procedure

1. Make sure that the basin is empty and secured with the basin lock.
2. Make sure that the discharge hose (optional) and the main cable have been disconnected from the appliance.
3. AD 740: Raise the hinged handle for transporting on the wheels. To do this, release the lock on the right and left of the hinged handle (item 1) and lift the hinged handle until the lock engages again.
4. Transport the dehumidifier to where it is going to be used.
5. AD 740: Fold the hinged handle back down again.

NOTE: The air must circulate freely. Do not cover the air openings. There must be a clearance of at least 1 m in front of the air outlet and the air filter.

Preparing the basin
Does not apply if an optional discharge hose is connected.

Procedure

• Slide the basin into the dehumidifier.
• Secure the basin with the basin lock.

Connecting an optional discharge hose
If necessary, the condensate water can be drained off via a discharge hose instead of into the basin.
To do this, proceed as follows:

ATTENTION! Inadequate appliance output!

• Do not place the end of the hose in the water (backwater possible).
•  Do not bend the discharge hose.
• Do not place any objects on the hose.

Procedure

1. Remove the basin.
2.  Attach a suitable hose (12 x 2 mm) to the discharge nozzle (Pos. 2) using a pipe clip.
3. Make sure that the end of the hose is lower than the start of the hose at the discharge nozzle. Minimumslope of 5 % (5 cm/metre).
4. Slide the top cover sheet (item 3) in front of the notch (item 4). To do this, loosen the screw on the cover sheet and slide the cover sheet to the top.
5. Run the end of the hose into a drain or a suitable container.

Electrical connection

Procedure

1. Make sure that the supply voltage is the same as the connection voltage in the technical data.
2. Provide an adequate fuse for the socket and the power supply.
3. Install an earth leakage circuit breaker in damp rooms and building sites.
4. Make sure that the main plug is suitable for the socket of the building.
5. Make sure that the socket used is earthed.
6. Plug the mains plug into the socket.
7. If necessary, connect one more appliance at most to the socket on the dehumidifier. If more than one appliance is connected, the integrated socket fuse will stop the appliances from working.

Operation

Unlock key lock
The key lock activates automatically if the control panel is inactive for 2 minutes.

Procedure

1. Hold the key down for 5 seconds.
   The key lock is released.

Setting the language

Procedure

1. Press the key twice in quick succession.
2. The display will show the current language.
3. Set the desired language using the arrow keys .
4. Wait 3 seconds until the selected language stops flashing.

Dehumidifying the room
NOTE: Allow the dehumidifier to rest in its final position for approx. 15 minutes before starting up, after transport, and after prolonged storage.

Procedure

1. Make sure that the condensate water can drain off through a discharge hose or into the basin.
2. Set the on/off button to “I”. “Start” will flash on the display. The dehumidifier will start operating. Operation is not possible when “Stop” or “Start” is flashing.
3. Set the desired humidity using the arrow keys . The dehumidifier will only start if the actual room humidity is higher than the target room humidity.
4. Select the fan level. To do this, press the key.
   The dehumidifier runs until the target room humidity has been reached or the basin is full, then it will stop running.
