INSTALLATION OF THE EXHAUST HOSE

The exhaust and the adapter have been matched exactly with this device. Do not replace either one with third-party products to ensure the appliance will continue to run properly.

1. Connect the exhaust hose adapter (1) with one end of the hose by plugging

in the hose and turning it lightly.

2. Connect the mounting plate (2) with the other end of the hose as described

3. Next, plug the adapter (1) into the hose

connector on the appliance. Position the adapter from the top before sliding it in completely until the adapter securely locks into place. The release tab must be pointing up.

4. Clamp the open end of the hose into the open

window. Make sure to seal the rest of the open window in order to conserve energy. If the window is fitted with an outer shutter, lower the shutter as much as possible.

1. The kit is suited for casement windows

and top-hung windows (top-hung roof windows that can be hinged open all the way).

2. The length of the sealing film is

approx. 390 cm. To calculate if this length is sufficient for your window, you need to measure all four sides of the window. If the total length of the window sides a+b+c+d is less than 390 cm, you can use the kit. If the window circumference is greater, you will need to use a different sealing option.

3. Start by cleaning the adhesive surface on the window pane and window sash

4. Now, apply the included adhesive hook-and-loop tape to each outer edge of

the window sash. The hook-and-loop tape is self-adhesive. Therefore, only pull off a small portion of the protective film at a time and apply the hook- and-loop to the window sash.

5. Next, apply the hook-and-loop tape to the window frame.

6. Spread out the sealing film and hold it up in front of the window with the

curved side facing you. Attach the film next, making sure that the middle of the sealing film is level with the middle of the window.

7. Proceed by connecting the hook-and-loop parts of the sealing film with the

hook-and-loop tape on window sash and window frame. The curved portion of the sealing film needs to be connected to the hook-and-loop tape on the window frame, while the straight portion of the sealing film must be joined with the hook-and-loop tape on the window sash.

8. Close the window and check if the sealing film is properly seated. Correct

9. Open the window again and pull down the zip fastener far enough for the

exhaust hose to be slipped through. Pull the zip fastener up again and make sure that the hose is seated firmly and cannot slip out.

10. When the air conditioner is not in use, remove the hose from the zip fastener.

You can now close the window normally. Another option is to remove the sealing film and to re-apply when using the air conditioner again. REMOTE CONTROL
