Before touching any tools or unpacking the unit, take time to prepare. A successful installation begins long before you drill the first hole.
1. Verify the Installation Location
The LG LIVX12AC2301BH is a wall-mounted split system. The indoor unit should be installed on an interior wall, ideally in the center of the room for even airflow. Avoid placing it near heat sources like ovens, direct sunlight, or electronics that generate heat.
Check that the wall can support the indoor unit’s weight—approximately 25–30 lbs. Use a stud finder to locate wall studs. If mounting on drywall, use heavy-duty toggle bolts or anchors rated for at least 50 lbs.
For the outdoor unit, choose a location with:
– At least 12 inches of clearance on all sides
– Good airflow (no obstructions like bushes or walls)
– Protection from rain, snow, and direct sunlight (a small canopy helps)
– Easy access for maintenance
Avoid installing near windows, doors, or areas where noise might disturb neighbors.
2. Check Electrical Requirements
The LIVX12AC2301BH operates on 208/230V, single-phase power and requires a dedicated 20-amp circuit. Do not share this circuit with other high-power appliances like microwaves or space heaters.
Check your electrical panel to ensure there’s an available 20-amp breaker. If not, you may need to install one—this is best done by a licensed electrician.
Use 12-gauge copper wire for the connection. The unit comes with a power cord, but hardwiring is recommended for safety and code compliance.
3. Gather Tools and Materials
Here’s what you’ll need:
- Drill and drill bits (including a 3-inch hole saw for the refrigerant line)
- Level
- Measuring tape
- Screwdrivers (Phillips and flathead)
- Wrench set
- Vacuum pump
- Manifold gauge set
- Refrigerant scale (if adding refrigerant)
- Pipe cutter and flaring tool
- Insulation tape and foam
- Electrical wire (12-gauge, if hardwiring)
- Mounting brackets and screws (usually included)
- Anti-vibration pads (for outdoor unit)
- Safety gear: gloves, goggles, and a dust mask
4. Review the Installation Manual
Always read the official LG installation manual that comes with your unit. It contains model-specific diagrams, torque specifications, and safety warnings. Keep it handy throughout the process.
Step 1: Mount the Indoor Unit
The indoor unit is the part you’ll see and hear inside your home. Proper mounting ensures stability, efficient airflow, and minimal vibration.
1. Position the Mounting Plate
Hold the mounting plate (included) against the wall at the desired height—typically 7–8 feet from the floor. Use a level to ensure it’s perfectly horizontal.
Mark the screw holes with a pencil. The plate should be centered and aligned with the room’s layout.
2. Drill Holes and Secure the Plate
Drill pilot holes into the wall at the marked spots. If mounting into studs, use the provided screws. For drywall, use heavy-duty anchors.
Secure the plate firmly. It should not wobble or shift when pressure is applied.
3. Drill the Wall Hole for Refrigerant Lines
Measure the distance from the bottom of the mounting plate to the floor. Add 6–8 inches to determine where to drill the hole for the refrigerant lines, drain hose, and electrical wiring.
Use a 3-inch hole saw to drill through the wall at a slight downward angle (about 5 degrees) toward the outside. This helps prevent water from entering the room.
4. Route the Lines and Wiring
Before mounting the unit, pass the refrigerant lines, drain hose, and electrical cable through the wall hole from inside to outside.
Wrap the lines with insulation tape to prevent condensation and heat loss. Secure the drain hose with zip ties to keep it straight and unobstructed.
5. Hang the Indoor Unit
Lift the indoor unit and hook it onto the mounting plate. Ensure it sits securely and level.
Connect the refrigerant lines and electrical wiring according to the manual. Use flare nuts and tighten them to the specified torque (usually 15–20 ft-lbs) to prevent leaks.
Step 2: Install the Outdoor Unit
The outdoor unit houses the compressor and condenser. It must be stable, level, and well-ventilated.
1. Prepare the Base
Place the outdoor unit on a solid, level surface—concrete slab, brick platform, or metal stand. Avoid soft ground like grass or soil, which can shift over time.
Use anti-vibration pads under the unit to reduce noise and prevent wear.
2. Position the Unit
Ensure the unit is at least 12 inches from walls, fences, or plants. Leave 24 inches of clearance above for airflow.
Face the fan side away from prevailing winds to improve efficiency.
3. Secure the Unit
Bolt the outdoor unit to the base using the provided mounting holes. This prevents movement during storms or high winds.
Step 3: Connect Refrigerant Lines
This is the most technical part of the installation. Improper connections can lead to leaks, reduced efficiency, or system failure.
1. Measure and Cut the Lines
The LIVX12AC2301BH uses 1/4-inch (liquid) and 3/8-inch (suction) copper refrigerant lines. Measure the distance between indoor and outdoor units and cut the lines to length, allowing extra for bending.
Use a pipe cutter—never a hacksaw—to ensure clean, burr-free cuts.
2. Flare the Ends
Use a flaring tool to create a precise flare on each end of the copper lines. This ensures a tight seal when connected to the service valves.
Clean the flares with a lint-free cloth to remove debris.
3. Connect to Indoor Unit
Attach the flared ends to the indoor unit’s service valves. Hand-tighten first, then use two wrenches (one to hold the valve, one to tighten the nut) to avoid twisting the lines.
Repeat for the outdoor unit.
4. Insulate the Lines
Wrap the entire length of the refrigerant lines with foam insulation. Secure with tape or zip ties. This prevents condensation and energy loss.
Step 4: Electrical Wiring
Electrical work must be done carefully to avoid shocks, fires, or damage to the unit.
1. Turn Off Power
Go to your electrical panel and turn off the breaker for the AC circuit. Use a voltage tester to confirm no power is present.
2. Connect Wires
If hardwiring, run 12-gauge wire from the breaker panel to the outdoor unit. Connect:
– Black wire to L1 (line 1)
– Red wire to L2 (line 2)
– Green or bare wire to ground
Follow the wiring diagram in the manual. Tighten all connections securely.
3. Seal the Junction Box
Close the outdoor unit’s junction box and ensure all screws are tight. Use weatherproof sealant around the wire entry points to prevent moisture ingress.
Step 5: Evacuate the Refrigerant System
Before charging with refrigerant, you must remove air and moisture from the lines. This is done with a vacuum pump.
1. Connect the Manifold Gauge
Attach the manifold gauge set to the service ports on the outdoor unit. Connect the yellow hose to the vacuum pump.
2. Open Valves and Start Pump
Open both the low and high-pressure valves on the manifold gauge. Turn on the vacuum pump.
3. Evacuate for 30–45 Minutes
Run the pump until the vacuum reaches 500 microns or lower. This ensures all air and moisture are removed.
Close the valves and turn off the pump. Wait 10–15 minutes to check for pressure rise. If it stays stable, the system is leak-free.
Step 6: Charge the System (If Needed)
The LIVX12AC2301BH is pre-charged for up to 25 feet of line. If your installation is longer, you’ll need to add refrigerant.
1. Weigh the Refrigerant
Use a refrigerant scale to measure the correct amount of R-410A. The required amount is listed in the manual.
2. Add Refrigerant
With the system off, slowly add refrigerant through the low-pressure port. Monitor the scale and stop when the correct weight is reached.
Never add refrigerant while the system is running unless instructed by the manual.
Step 7: Final Checks and Startup
Before turning on the AC, perform a thorough inspection.
1. Inspect All Connections
Check refrigerant lines, electrical wires, and drain hose for tightness and proper routing.
2. Test the Drain
Pour a small amount of water into the indoor unit’s drain pan to ensure it flows freely outside. Clogged drains cause leaks and mold.
3. Power On and Test
Turn the breaker back on. Set the remote to cool mode and fan speed to high.
Listen for unusual noises. Check that cold air is blowing within 5–10 minutes.
Use a thermometer to measure the temperature drop—it should be 15–20°F cooler than the return air.
