SHIPPING DAMAGE
Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing requesting inspection by the carrier’s agent.
GENERAL
The QWS48A series is designed for use with the QTEC Series Air Conditioners and Air Source Heat Pumps. The QWS48A is for use with wall thickness of 5 to 14 inches. One QWS48A series wall sleeve is required for each QTEC Model to be installed.
The equipment covered in this manual is to be installed by trained service and installation technicians.
These instructions explain the recommended method to install the wall sleeve.
These instructions and any instructions packaged with any separate equipment required to make the entire air conditioning system should be carefully read before beginning the installation.
While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made.

WOOD FRAMED INSTALLATION
INSTALLATION – WOOD FRAMED WALLS
For wood frame construction walls, the dimensions of the opening must be 48 inches tall by 43 inches wide. A 2 x 6 header will be required for the opening. The sides of the opening must have trimmer studs to support the header, and to provide a structural member on which to fasten the sleeve. (See Figure 1.) All of the dimensions are referenced from the finished floor height.
After the opening is framed in, a treated 2 x 6 bottom support and seal plate must be cut to fit in the bottom of the opening. Construction adhesive should be applied to the 2 x 6 before it is put in place. (See Figure 2.) This will help hold the plate in place and provide an additional seal for the bottom of the opening. The treated 2 x 6 must be fastened to the bottom of the opening flush to the finished surface of the outside wall. The 2 x 6 must be sealed to the outside wall with construction adhesive. Any gaps between the sides of the 2 x 6 plate and the opening must also be sealed. See Figure 2. NOTE: The actual thickness of 2 x 6 must be
Once the opening is framed, the sheeting can be installed, the sheeting material must not extend into the opening.
The sleeve should be test fit into the opening to make sure of the dimensions. The sleeve must be inserted into the opening from the outside of the building. The bottom of the sleeve must be level from side to side, and the sleeve must be square in the opening. A slope is built into the bottom of the sleeve from the inside to the outside. This will allow any water that gets into the sleeve to drain out. Once the test fit is completed, the sleeve must be removed from the opening, and two 1/4 inch beads of sealant must be applied to the mounting flanges of the sleeve. (See Figure 3.)
