Contents of Installation Kit

Selection of Installation Location

1. Place the unit on a level floor.
2. For best performance. allow at least 20" of air space on all sides of the unit for good air circulation
3. Place the unit near a window. The hose and diffuser will be used to connect the air conditioner to the window installation kit to vent exhaust air outside.

NOTE The length of the flexible vent hose is specially designed according to the specification of this product. Do not replace or extend it with a hose that is not specifically designed for use with this product as this could cause malfunction.

Assembling the Flexible Vent Hose Set

1. Pull evenly on the folds to extend one end of the flexible vent hose.
2. Insert the mounting bracket on to the end of the vent hose, aligning the mounting bracket threads with the notch on the flexible vent hose.
3. Turn the mounting bracket counterclockwise though 5 rotations or until the flexible vent hose is firmly attached.
4. Repeat the process to attach the diffuser to the other end of the flexible vent hose.

Attaching the Flexible Vent Hose Set

Round Type

Insert the mounting bracket and rotate it to lock it in place.

Square Type

Insert the mounting bracket

Window Vent Panel and Extensions

The window installation kit allows you to install the air conditioner in most vertical-sliding windows 18″ to 50″ wide, or horizontal-sliding windows from 18″ to 50″ high.

1. Select the panels required based on the window opening, as shown above.

2. For longer window openings, assemble and adjust the panels to fit the window opening. Use type A screws (included) to fix the panels together at the proper length.

Window Installation Kit

(Includes 1 window vent panel and 3 extension panels)

For an 18″ window opening, use the window vent panel (Panel A) by itself. Fig.a

For window openings from 19″ to 25″, use the window vent panel (Panel A) and extension Panel B. Fig.b

For window openings from 27″ to 34″, use the window vent panel (Panel A) and extension Panel D. Fig. c

For window openings from 35″ to 50″, use the window vent panel (Panel A) and extension Panel C and Panel D. Fig. d

Installing Vent Panels

1. Attach the long adhesive foam weather seals to the top and bottom sides of the window vent panel assembly. Attach the short foam weather seals to the right and left sides of the panel assembly. (Attaching the foam weather seals to the panel assembly rather than the window sash and frame makes for easier cleanup when removing the panel assembly.)

2. Insert the panel assembly in the bottom sash channel. Use care when installing the assembly, which will now fit very tightly in the opening. Close the sash tightly against the top of the panel assembly.

3. If needed, install the included security bracket with type B screws.

4. Measure and cut the included non-adhesive foam to fit the window opening. Stuff it between the window sashes to prevent air and insects from getting into the room.

5. Align the tabs on the diffuser with the slots in the vent panel. Insert the diffuser into the opening in the vent panel and slide the diffuser all the way over to lock the tabs in place. Position the diffuser with the round opening above the bottom of the vent panel to avoid interference from the window sill.

6. Insert the type C screw in the hole in the diffuser to prevent the diffuser from sliding out of the vent opening. If the diffuser is positioned correctly, the screw should just clear the edge of the opening in the vent panel. You should not have to drill through the vent panel.

NOTE

• For a tighter seal, use "no residue" duct tape (not provided) to seal any gaps around the installed panel assembly, around the diffuser, and between the sashes.
• For best results, keep the vent hose as short and straight as possible. However, shape the diffuser end of the vent hose into an inverted U shape just inside the window to allow any rain or condensation to drain out the window.
