WLCA/WLHA MOUNTING preparation

The WLCA/WLHA must be mounted plumb and level to a vertical surface to prevent unit vibration and/or unwanted noise. It is recommended that the unit be mounted directly to a smooth surface such as Sheetrock® wallboard or similar material. If mounting to a masonry block wall, there should be a smooth barrier between the unit and the masonry block

surface to absorb any potential vibration and prevent the formation of condensation on the wall.

Note: If excessive noise or vibration is experienced from a unit mounted to a ma- sonry block wall, check to ensure the unit is plumb and level. If noise or vibration persists, contact the wholesale distributor.

WLCA/WLHA HIGH WALL unit MOUNTING

1.After determining the best location for the unit, use the cardboard template provided in the packaging.

2.Mark where the piping, electrical wiring and condensate drain should penetrate the wall.

3.Determine the appropriate hole size and cut through the wall.

4.Use the supplied wall bracket. For shipping purposes, the wall bracket is fastened to the back of the unit.

Remove and discard these screws

5.Secure the bracket to the wall with the appropriate screws (for wood) or an- chors (for masonry). Ensure the bracket is mounted in a manner that will support the weight of the unit.

Note: The wall hanging bracket slot is NOT located in the center of the unit.

6.To mount the unit to the bracket, align the mounting slot on the back of the unit over the bracket and make certain it fits properly.

Note: Piping may be roughed in before wallboard or panels are placed in new construction. PVC pipe (3” or 4” I.D.) may be used as a pipe chase.

Note: Panels should remain on the unit at all times, while powered and in opera- tion. Service should be performed by a QUALIFIED service agency. An annual system check by a qualified service tech- nician is recommended.
