4.2 Exhaust Hose Installation
The exhaust hose must be installed to vent hot air outside the room. Failure to do so will prevent the unit from cooling effectively.
- Connect the hose connector to one end of the flexible exhaust hose.
- Connect the other end of the hose to the exhaust opening on the back of the air conditioner.
- Attach the rectangular hose connector to the free end of the exhaust hose.
- Extend the exhaust hose to a window or wall opening.
- Use the provided window sealing kit to secure the hose in the window opening and prevent hot air from re-entering the room. Ensure the window is sealed as tightly as possible around the hose.
