Step 2. Install drain kit in wall sleeve.
Step 4. Install wall sleeve in wall opening.
For condensate to drain properly inside the unit, the sleeve must be installed properly:
•level from right to left
•with a slight downward pitch from the indoor side to the outdoor side
Note: If equipment is 230/208 volt, verify the electrical receptacle is located within 52 inches of the sleeve’s right hand corner. Do not use an extension cord.
Note: For installation procedures, please refer to the Installation Guide that accompanied the accessory.
4.Slide the chassis into the wall sleeve until the chassis flanges contact the front edge of the wall sleeve. See Figure 14.
5.Secure the chassis to the wall sleeve using three screws on each side of the chassis to ensure a proper seal between the chassis and the wall sleeve . The screws are supplied in a plastic bag which is attached to the power cord. See Figure 15.
6.Verify the indoor and outdoor grilles are free of airflow obstructions.
7.Make the power supply connections as detailed in the next step.
Drain kits are available for indoor or outdoor installation to help condensate drain from either the right or left side of the wall sleeve externally, or from the bottom of the sleeve internally.
Note: For installation procedures, please refer to the Installation Guide that accompanied the accessory.
If you do not use the drain kit, condensate will drain out of the rear of the wall sleeve. The drain kit must be installed before the outdoor grille is installed.

An outdoor air grille directs airflow for proper unit operation and to protect the outdoor coil. Install the grille before installing the chassis.
Outdoor air grille options are either a stamped grille or an architectural grille. When replacing an old chassis with an existing grille, please check with your HVAC representative to determine if the new chassis can be used with the old outdoor grille.
