OUTDOOR UNIT INSTALLATION
Ground Pad or Wall Hangers Installation
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.
Outdoor Unit Risers Installation
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.
NOTE: To meet Florida Wind oad criteria, the 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
41/2-in fromany concrete edge. The concrete thickness must exceed 1.5 times the anchor depth.
Condensate Drain Installation 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. ocate and select a 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.
5. All non-used drain holes should be plugged.
Drain Fitting Installation
13

Carefully cut hole in the side of the front panel for piping to enter indoor unit as shown below.
Find and mark the proper location for the wall hole. Use table below to determine recommended
wall hole size for your unit size.
3.
Cut the wall hole with a 5° to 10° downward slant to the outdoors.
4. Insert a wall sleeve into hole to prevent damage to refrigerant pipes, insulation,
condensate drain hose and wiring.
5. Proper weather proofing of the wall
surface and wall sleeve is essential to
assure a trouble-free installation. Apply
sealant, caulking or equivalent weather
proofing material around the perimeter
of the wall sleeve (interior & exterior) to
eliminate outdoor air and water leaks
into the living space.

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.

NOTE: For maximum serviceability, it is recommended to have refrigerant piping and
drain connections on the outside.
Piping Connections to Indoor Unit:
1. Feed refrigerant pipes, drain hose and interconnecting wires assembly
through wall hole from outdoor to the indoor unit.
2. Adjust the length and carefully bend refrigerant pipes to meet indoor
unit refrigerant pipe connections with proper tools to avoid kinks.
3. Apply a small amount of refrigerant oil to the flare connection on
the refrigerant pipes.
Piping Preparation:
1. Do not open service valves or remove protective caps on pipes until all connections are made.
2. Keep tubing free of dirt, sand, moisture and contaminants.
3. Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall
thermal pipe insulation.
4. Bind refrigerant pipes, the condensate hose and interconnecting cable together with
cable ties at 12-inch intervals.
Use refrigeration grade piping ON Y. Uses of other piping will void the Manufacturer’s Warranty.
