General safety information
WARNING! Risk of explosion, burns and poisoning from refrigerants!
The appliance contains an odourless, flammable refrigerant which, if handled incorrectly, could result in explosions and fire as well as injuries and burns.
The refrigerant circuit is pressurised.
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 m ^2 .
- Any work to the refrigerant circuit must be performed by the manufacturer or the manufacturer's au-
thorised technical personnel. Before working on the refrigerant circuit, it must be depressurised 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.
→ Only allow the manufacturer or authorised personnel to carry out work on electric components.

7 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! Reaching into the grille of the air intake area can result in crushing or cutting!
- U se the handles to transport the dehumidifier.
Do not reach into the air intake area.
CAUTION! Crushing or ergonomic damage when transporting the dehumidifier!
U se the handles to transport the dehumidifier.
The dehumidifier must be transported by two people.
Procedure
- Make sure that the condensate water is drained away.
- Make sure that the appliance is switched off and the mains cable has been disconnected.
- Transport the dehumidifier to where it is going to be used.
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 air intake area.
Connecting the discharge hose
It is essential to connect the drain hose provided.
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
- Attach the drain hose to the Water outlet on the front of the appliance.
- Make sure that the end of the hose is lower than the start of the hose at the Water outlet. Minimum slope of 5 % (5 cm/metre).
- Run the discharge hose away from the dehumidifier to a drain or into a suitable container (recommended container volume = 90 litres).
Electrical connection
Procedure
- Make sure that the supply voltage is the same as the connection voltage in the technical data.
- Provide an adequate fuse for the socket and the power supply.
- Install an earth leakage circuit breaker in damp rooms and building sites.
