STEP 1 - inside
1. Locate the cardboard wall template.
2. Place the template on the wall at the installation location.
3. Use the template
to mark the location
of the drill points for
the mounting screws
and wall hole. Make
sure that the drill
points for the mounting
screws are located on
wall studs.
4. Remove the template.
STEP 2 - inside
1. Drill screw holes at the indicated points into the wall
studs.
2. Remove the mounting bracket from the rear of the
interior air handler by removing the screw(s) holding it in
place.
3. Screw the metal bracket to the wall according to the
template.
4. Use a level to
ensure the
mounting plate is
flush and level.
STEP 3 - inside
1. Drill a 3.5 inch diameter hole through the wall, at a
slightly downward angle (to ensure proper drainage), to
accommodate the line set, condensate drain line, and MC
cable to the exterior condenser.
2. Carefully bend piping at the back of the air handler until
it is sticking straight out from behind the unit.
3. Using electrical tape, lightly tape the refrigerant piping &
condensate drain line at the back of the indoor unit into a
bundle (this will make it easier to pass through the wall
hole). The drain pipe MUST be on the bottom. DO NOT
wrap the end of the piping (connectors & drain hose)
you will need access to them for later steps.
4. Insert wall hole sleeve into wall hole.
5. Push the MC cable and piping bundle through the wall
hole.
