4.3 DRAINAGE

The automatic evaporation system uses the collected condensate to cool the condenser coils for more efficient performance. It is not necessary to empty the drainage container in cooling mode, except in drying mode and under highly humid conditions. The condensate evaporates at the condenser and is discharged through the exhaust hose.

For continuous operation or unattended operation in drying and heating mode, the connected drain hose must be connected to the unit. The condensate can be automatically directed into a bucket or drain by the gravity principle.

• Switch off the unit.
• Remove and store the outlet opening's plug.
• Connect the drain hose properly and ensure that it is not kinked and is free of obstacles.
• Place the hose outlet over a drain or bucket and ensure that the water

can flow out of the unit without obstruction.The end of the hose must not be immersed in water.
To avoid spilling water:Since the negative pressure of the drain pan for condensate is high, lay the drain hose downwards towards the floor. The angle of inclination should exceed 20 degrees.Straighten the hose to avoid creating a siphon.

5. CLEANING AND CARE INSTRUCTIONS

5.1 CLEANING AND CARE

Cleaning the air filter (every two weeks)

Dust deposits on the filter and restricts air circulation. The restricted air circulation reduces the system's efficiency and may cause damage to the system in the event of blockage.

The air filter must be cleaned regularly. The air filter can be removed for easy cleaning. Do not use the unit without an air filter, as the evaporator may be contaminated.

• Switch off the unit.
• Pull the mains plug
• Remove the filter screen from the unit.
• Use a vacuum cleaner to suck dust from the filter.
• Turn the filter over and rinse the air filter under running water. Allow the water to flow through the filter in the opposite direction to the airflow. Set the filter to one side and allow it to air-dry completely before reinstalling it.

Warning!

The surface of the evaporator must not be touched with bare hands, as this can result in damage to the slats and injury.

6. DECOMMISSIONING

6.1 STORAGE

Long-term storage – If the unit will not be used for an extended period of time, it is advisable that it be cleaned and dried completely. Store the unit according to the following steps:

• Remove the plug from the socket. Remove the exhaust hose and the window spare part stored with the unit.
• Drain the remaining water from the unit.
• Clean the filter and let it dry completely.
• Replace the filter
• The unit must stand upright during storage.
• Store the machine in a ventilated, dry, non-corrosive environment and in a safe place indoors.

ATTENTION:

The evaporator inside the system must be dried before packing to avoid damage to components and moulds. Disconnect the unit from the mains and place it in a dry, open location for several days to dry. Another way of drying the system is to switch the machine on, set it to a low-wind ventilation mode and maintain this condition until the drainpipe becomes dry to keep the inside of the enclosure dry and prevent mould growth.

6.2 TRANSPORT

1. Before commissioning, set upright and leave to stand still for MIN. 12 HOURS! This protects the compressor, extends its service life considerably and thus prevents a loss of cooling capacity.
2. The air conditioning unit must always be placed on the floor with PARTICULAR CARE! Otherwise, cracks may appear in the base plate and the condensate tray, causing condensate to drip onto the floor.

We DO NOT provide warranty services for damage caused by improper use!

• If an indirect refrigerant circuit is used, check that refrigerant is present in the secondary circuit;
• The markings on the units remain visible and legible. Illegible markings and signs must be replaced;
• The refrigerant pipes or components are installed so that they are highly unlikely to be exposed to any substance that could corrode components containing refrigerant, unless they are made of corrosion-resistant materials or are adequately protected against corrosion.

8.9 Electronic verification

The repair and maintenance of electrical parts requires initial safety tests and procedures for checking the parts. If there is a defect that could jeopardise safety, no power supply may be connected to the circuit until the defect has been sufficiently remedied. A temporary solution must be found if the error cannot be rectified immediately and it is still necessary to continue operation. The system's owner must be informed of this so that all parties involved are instructed accordingly. The initial safety checks include:

• Discharging the condensers: This must be done safely to avoid the risk of sparking;
• Ensuring that no electrical components or lines are live when charging, restoring or flushing the system;
• Ensuring that a continuous earth connection exists.

WARNING!

The system must be installed in rooms that meet the specified room size; see the technical data regarding this matter.

The The system may not be installed in a place where flammable gas could escape.

NOTE!

The manufacturer may provide other suitable examples or additional information about what the refrigerant smells like.
