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.

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.
