Install Ground Pad or Wall Hangers
1. Determine proper location for outdoor unit.
2. Follow all instructions provided by manufacturer for installing wall hangers or ground pad.
3. Verify the wall hangers or ground pad can safely support the weight of the outdoor unit.
4. Verify the wall hangers or ground pad is level and meets all outdoor dimensional clearances.
Install Outdoor Unit Risers
If the outdoor unit requires added elevation above the ground, installing riser legs will provide
a sturdy and stable solution. Follow all instructions provided by manufacturer for installing
riser legs to outdoor unit.
NOTE: Riser legs will also help absorb vibrations and noise while facilitating proper drainage.
Florida Wind Load Requirements state that outdoor unit must be anchored to
concrete pad using four 3/8-in diameter Power Wedge Bolt Plus (or equivalent)
with 1-in diameter fender washers. Anchor bolts must be embedded into
3,000 PSI minimum concrete at a distance of 4 1/2-in from any concrete edge.
The concrete thickness must exceed 1.5 times the anchor depth.
Install Condensate Drain for Outdoor Unit
During normal heating and defrost operation,
the outdoor unit will generate condensate water.
The condensate water should be routed to a safe
location through the drain hose.
1. Locate drain hole on bottom of outdoor unit.
2. Install the outdoor drain fitting into hole on
the bottom of outdoor unit as shown.
3. Connect the drain hose to drain fitting.
4. Route drain hose to safe location for proper
drainage of excess condensate water.

OUTDOOR UNIT PREPARATION
Step 4
If indoor unit refrigerant piping is going to exit from the rear:
1. It is recommended that the refrigerant pipe flare connectors extend through the wall
to the outside. In some situations field-fabricated piping extensions will be required to
extend the indoor unit refrigerant flare connections to the outside of the wall.
2. Use mounting bracket diagrams and dimensions to find and mark the proper location
for the wall hole.
If refrigerant piping is going through the right or left side of front panel:
1. Use a small saw blade to carefully cut a U-shaped hole in the side of the front panel.
The hole must be large enough for refrigerant pipes, condensate hose and wires.
2. Determine and mark proper location for wall hole.
3. Use table below to determine recommended wall hole size for your unit size.
4. Cut the wall hole with a 5° to 10°
downward slant to the outdoors.
5. Insert a wall hole sleeve into hole to
prevent damage to refrigerant pipes,
insulation, condensate drain hose
and wiring.
6. Seal around wall hole sleeve with
caulk or foam to weatherproof.
