Delivery

All devices are carefully packed before shipping. Please check the device immediately after delivery. Make a note of any damage or missing parts on the delivery note and inform the forwarding agent and your contractual partner. No warranty can be assumed for later complaints.

Erecting the device

Make sure that all air intake and air outlet openings are free; observe the minimum clearances (Fig. 2).
Erect the device on a solid, even foundation (Fig. 3)
Make sure that people and sensitive objects such as plants are not directly affected by the emerging air.
Connect the device to a properly installed plug socket (230V/50Hz) (Fig. 5)
Insert the batteries into the remote control. To do so push up the cover on the back side of the remote control and insert the batteries while

observing the proper polarity. Observe the marking inside the compartment (Fig. 6).

Check whether the plug of the condensate drain spout has been provided and whether it has been properly inserted. There is otherwise a danger of water emerging.

Exhaust air conduction

During the operation of the air conditioner, the device creates humid exhaust air that must be conducted outside of the room so that the cooling effect can be maintained

Observe the following notices:

Plug the air outlet hose included in delivery onto the air outlet on the rear panel of the device.
- Lock both catches on the air outlet into both openings of the air outlet hose.
- Keep the air outlet hose as short as possible (max. length 1400 mm).
Always lay the air outlet hose with a constant upward incline from the device to the wall/window. Make sure it has

Functional principle of the cooling process

The air conditioner cools the air by removing heat from it. The fan (circulation air) conducts cooled air into the room. The heat that the device has removed from the air is conducted outside via the air outlet hose.

Humidity is removed from the air and drips as condensate from the evaporator onto the hot condenser and evaporates. Excess condensate drips from the condenser into a collection tray and conducted from there to the condenser again using a rotor, evaporated, and then conducted away with the exhaust air flow

Fig. 15/16 Cleaning the air fi lte

With low cleaning effort, you can guarantee malfunction-free operation and a long service life

Use only mild, environment-friendly cleaning agents.
Regularly clean the ventilation slots.
Clean the device as required, but at least once a year, with a moist cloth and lukewarm water
Do not expose the device to direct water spray

CAUTION

Always turn off the device and pull the mains plug before cleaning!

Never operate the device without the air fi lte,

Cleaning the air fi lte

Clean the air fi Iter regularly but at least every 100 operating hours. In case of strongly contaminated air, the period is reduced accordingly

1. Switch off the device and pull the mains plug.
2. Remove the filter from the device (Fig. 14).
3. Clean the filter using a vacuum cleaner or, in case of heavy soiling, carefully using lukewarm water (Fig. 15/16).
4. Let the filter air-dry and their reinsert it

Draining the condensate

The condensate evaporates during operation and is then conducted outside with the exhaust air via the air outlet hose.
In case of extreme humidity, the device collects condensate in a reservoir. If the permissible level is exceeded, the red fault LED lights up and the device shuts down.
The reservoir must be emptied via the condensate drain spout (Fig. 17).

Trouble Shooting

The device is not functioning and the control panel remains dark.

Make sure that

• the mains plug is properly inserted;
• there is no power failure;
  • the mains voltage is present (fuse)

- Check the mains supply line for damage.

The device is not cooling properly.

• Check the mode: the "Cool" LED must be lit.
  For an optimum cooling capacity, close the curtains and blinds. In addition, make sure the windows and doors are closed.

Make sure that

• the air outlet hose has been properly attached. It may not be bent, declining, or laid in a tight curve;
• no foreign bodies impair the exhaust or intake air supply (observe the minimum clearances);
• the air directing plate fi ns are free of soiling or foreign objects
• the set temperature is not too high (operating limits of the device: 16 to 35^ ).

DANGER

Contact your dealer or contractual partner if the device cannot be commissioned.

Never open the device housing.

Never perform work on the cooling circuit or the electrical equipment.

The device is not functioning and the "Timer" time de ay LED is fl asling.

- "Timer" time delay is programmed. Delete the timer setting.

The device is not functioning and

"E1" is being shown in the display.

The room temperature lies outside the operating range of 16 to 35°C. Wait until the room temperature lies in the working range (reduce the incident of sunlight and close windows and doors, if necessary).

The device does not react to the remote control.

Make sure that

• the batteries are functioning; change them if necessary;
• the batteries are inserted with the correct polarity (cf. the marking);
• there are no objects between the remote control and the device (reach of approx. 5 m).

The device deactivates automatically. The fault LED fl ashes and a signal sounds (reservoir full).

To drain the reservoir, proceed as follows

1. Switch off the device and pull the mains plug.
2. Place a fl at tray under the condensate drain spout and remove the plug (Fig. 17).
3. After the condensate has drained, reinsert the plug firmly

Condensate is emerging.

Make sure that

• the device is on a horizontal foundation;
• the air outlet hose is properly attached;
• the plug is firmly inserted in the condensate drain spout.

Taking out of service

To take the device out of service, deactivate it first by pressing the "Power" button. Then pull the mains plug.

If the device must be shut down for a longer period of time, for example, for storage during the winter, observe the following:

1. Let the machine run for about two hours in the "Fan" mode to dry the surface of the evaporator plate fi ns. In this way, the residual moisture is removed from the device and you can prevent unpleasant smells during recommissioning.
2. Switch off the device, pull the mains plug, and roll up the mains supply line
3. Drain the condensate (s. p. 6).

Warranty

The function of the device was precisely checked several times at the factory. If malfunctions that are not described in the "Trouble Shooting" chapter (s. p. 7) still appear, contact your dealer or contractual partner
In order for REMKO to assume the warranty, the "Warranty Certifi cate" included in delivery must be completely filled out and sent to REMKO GmbH & CO KG immediately after purchasing or commissioning

CAUTION

The manufacturer is not liable for damage that occurs due to nonobservance of manufacturer instructions or the legal requirements or due to unauthorised changes to the device.

Environment and Recycling

■ Dispose of the packaging in an eco-friendly manner
Do not dispose of the device in domestic rubbish
Both the refrigerant and the plant parts are subject to special disposal conditions
The refrigerant used belongs to the chlorofl uorocarbon refrigerant group. It is released into the air due to damage to the cooling circuit, injury to the respiratory organs of people and animals will not occur

Installation Instructions for the Wall

■ Create a core hole in the outside wall (max.- wall thickness of 480 mm) with a diameter of at least 135 mm.
Take the minimum distance of 430 mm between the floor (mounting surface of the device) and the centre of the wall bushing into consideration.
- Insert the telescopic pipe into the wall bushing
To prevent cold bridges, insulate the telescopic pipe with suitable insulating material.
■ Wall the telescopic pipe into the core hole in such a way that it is fl ush to both sides of the wall.

Mount the protection grill on the outside of the wall (make sure it is protected from rain)
Fix the trap to the inside.
The "top" label on the trap must be legible from the inside
When taking the device out of service, for example, at the beginning of winter, close the opening of the trap using the sealing cap to prevent air circulation
