Before Installation Starts

First, let’s prepare everything you need to install your portable air conditioner in the sliding door.

Chose Installatoion Location

First, choose a good location for your portable air conditioner system. Preferably, you should position your air conditioner beside an exterior window or a sliding door with an electrical outlet nearby. This is critical for several reasons:

  • Cables, particularly if they are unprotected, can be a potential hazard.
  • Extension cables should not be utilized since they are a fire danger.
  • The power wire should be able to reach the outlet without becoming too strained. Likewise, the exhaust hose should reach the door without being excessively stretched. The hose’s optimum position must be as short and upright as feasible.
  • The machine must be positioned on firm level terrain and in an area devoid of obstacles including furniture, partitions, shrubs, and so on, since they might block airflow and lower the effectiveness of the air conditioner.

The least permissible space between the machine and the wall would be specified in the device’s user manual. Place your device according to the distance.

You may begin installing the device after it has been properly positioned.

Prepare Things You Need

Then check the portable AC vent kit and see if it contains everything you would need to install. The kit should have:

  • Exhaust connector(s)
  • Exhaust hose
  • Hose adaptors
  • Door/window brackets
  • Slider connectors
  • Screws, weather strips and other accessories are optional

You should also make sure that the bracket is suitable with your door. They are typically designed to slide vertically and horizontally in most conventional windows or doors. If it does not fit precisely, you might have to make some adjustments. The width of your door will decide whether the adaptor kit has to be trimmed or expanded. You may simply add to the kit by using plexiglass, plywood, or cardboard.

Prepare the Installation Kit

The kit must be vertically positioned after opening the door and stretched until it meets the frame height. For a sliding door, you may require a double bracket (a regular bracket plus a filler bracket).

Install the weather stripping/foam to seal the opening and keep bugs and warm air out. To keep the kit in position, secure it with screws (if provided) and shut the door sash.

Attach the Exhaust Hose

This procedure differs depending on the model. You should follow the installation guide attentively to determine your next move.

Attach an exhaust connector to the unit initially. Some models may already have this installed. Plug the exhaust connector to the vent hose. Connect the vent hose’s opposite end to the adapter.

Stretch the hose until it can be connected to the slider kit. When stretching the hose, keep in mind that you would like it to be short (probably around 8 to 9 ft.) and straight until it reaches the door to prevent impeding air movement.

Or else, the cooling function of the machine would be compromised, and the unit may possibly be damaged.

You can tweak the kit sliders till the gap between the frame and adapter is entirely closed. You must also make certain that everything is securely fastened. Duct tape may be used to fasten the connections at both sides of the vent line.
