Accessories

- Exhaust hose
- Flat type adaptor – for insertion over the hose and into the window spacer (or into a hole in the wall/window).
- Inward connector – connect the unit with the exhaust pipe
- Drain tube for continuous drainage
- Remote control
Installation
Feed the exhaust hose through the window and slide the window across so that the spacer is held securely. This technique may also be used for sash windows.
Use only the hose provided and clip the exhaust hose to the back of the air conditioner. Avoid kinks and bends in the exhaust hose, as this will cause expelled moist air to build up, causing the unit to overheat and shut down.
Fixing The Wall Seal
The installation of the window seal is simple. You can attach the seal to a tilted window, a side-opened window, or a roof window. We have chosen a side-opened window for demonstration purposes. It is particularly suitable because the exhaust hose can be attached to the side far down.
The Velcro tape is attached to the three open sides. The side where the window is against the frame is left out. Clean and dry the window frame beforehand so that the tape adheres.
Attach the Velcro tape on the left, on the top, and on the bottom of the window frame. We recommend that you cut the tape into strips for each window side first.
Now attach the Velcro tape to the inner window sides.
Stick the window sealing to the Velcro strips on the window frame first (starting with the top), then on the Velcro strips on the window. Push the exhaust air tube of the air conditioner through the hole, which can be adjusted in height and size.
