Choosing The Right Location
Choose a room size that fits the air conditioner’s cooling power. Small rooms need less cooling, big rooms need more. Good ventilation helps the unit work well and stops hot air buildup.
Avoid placing the air conditioner where sunlight shines directly. Sunlight heats the unit and lowers its cooling ability. Keep the unit away from furniture or curtains that block airflow. Clear space around the unit allows air to flow freely and cool better.

Unpacking And Checking Components
Carefully open the box and remove all items. Check for the portable air conditioner, exhaust hose, window kit, and remote control. Make sure the parts match the list in the manual. Look for any damageor missing pieces. Contact the seller if anything is wrong.
Gather these tools before starting:
- Screwdriver
- Measuring tape
- Scissors(to cut window kit if needed)
- Level(optional, for window installation)
Having the right tools helps the installation go smoothly.
Setting Up The Exhaust Hose
First, connect the exhaust hoseto the air conditioner unit. Push the hose firmly into the outlet until it clicks or fits tightly. This helps the hot air flow outside. Make sure the connection is secureto avoid leaks.
Next, attach the other end of the hose to the window kit. The window kit holds the hose in place and closes the window gap. Slide the hose into the window kit’s round opening. Tighten any clamps or screws to keep the hose steady.
- Check that the hose is not bent or crushed.
- Keep the hose as straight and short as possible.
- Seal any gaps around the window kit to stop warm air from entering.
Installing The Window Kit
Adjust the window kit by sliding its parts until it fits your window. The kit should fill the gap without leaving any space. Use the extension panels if your window is wide.
Place the kit securely in the window frame. Make sure it sits flat and tight to avoid air leaks. Use screws or clips provided to hold it firmly.
- Measure the window width before adjusting the kit.
- Extend the kit panels to match the window size.
- Check that the kit is stable and does not move.
- Seal edges with foam strips if needed for better fit.
Sealing And Insulating
Foam stripsand seals help stop cold air from escaping. Use them around window edges and AC hose openings. This keeps the room cool and saves energy.
Check for gaps where air can leak. Even small cracks let hot air in and cold air out. Seal all gaps tightly for best results.
- Clean the surface before applying foam strips.
- Press strips firmly to stick well.
- Use window seals to close any open spaces.
- Check seals regularly for wear or damage.
Good sealing means your air conditioner works better and uses less power.

Maintenance Tips
Clean filters often to keep the air fresh and cool. Dirty filters block airflow and reduce cooling. Remove the filter and wash it with warm water. Let it dry completely before putting it back. This keeps the unit working well and saves energy.
Store the air conditioner properly when not in use. Drain all water from the unit to prevent mold. Cover it with a cloth or plastic to keep dust away. Keep it in a dry and cool place. This helps the unit last longer and stay clean.
