Installing the Outdoor Unit
1. Choose a Location: Select a location for the outdoor unit that is well-ventilated, protected from direct sunlight, and has enough space for airflow.
2. Install the Condenser Pad: Place the condenser pad on the ground and level it using a level.
3. Mount the Outdoor Unit: Carefully lift the outdoor unit onto the condenser pad and secure it with the provided bolts.
Installing the Indoor Unit
1. Choose a Location: Determine the location for the indoor unit on the wall, ensuring it is not obstructed by furniture or curtains.
2. Mount the Mounting Plate: Install the mounting plate on the wall using the provided screws.
3. Hang the Indoor Unit: Lift the indoor unit and hook it onto the mounting plate. Secure it with the provided bolts.
Connecting the Line Set
1. Run the Line Set: Connect the copper pipes and electrical wires from the outdoor unit to the indoor unit. Ensure the pipes are flared properly.
2. Tighten the Flare Nuts: Use a wrench to tighten the flare nuts on the refrigerant lines.
3. Insulate the Line Set: Wrap the line set with insulation to prevent condensation.
Electrical Wiring
1. Connect the Electrical Wire: Connect the electrical wire from the outdoor unit to the indoor unit.
2. Secure the Wiring: Use electrical tape or wire nuts to secure the wiring connections.
3. Check the Wiring: Double-check that all electrical connections are tight and secure.
Evacuating the System
1. Connect the Vacuum Pump: Attach the vacuum pump to the service port on the outdoor unit.
2. Evacuate the System: Run the vacuum pump for at least 30 minutes to remove any air or moisture from the system.
3. Close the Service Valve: Close the service valve on the outdoor unit once the system is evacuated.
Charging the System
1. Connect the Refrigerant Line: Attach the refrigerant line to the service port on the outdoor unit.
2. Open the Refrigerant Valve: Slowly open the refrigerant valve to allow refrigerant to enter the system.
3. Monitor the Pressure: Check the pressure gauge on the refrigerant line to ensure the system is properly charged.
Testing the System
1. Turn on the Power: Restore power to the air conditioner split system.
2. Check the Operation: Turn on the unit and check if it is cooling or heating properly.
3. Inspect for Leaks: Inspect all connections and joints for any refrigerant leaks.
Troubleshooting
- Unit not cooling/heating: Check the power supply, refrigerant levels, and airflow.
- Loud noises: Inspect the fan blades and motor for any obstructions or damage.
- Refrigerant leak: Contact a qualified technician to repair the leak.
Maintenance Tips
- Clean the air filters regularly.
- Inspect the outdoor unit for debris and clean it as needed.
- Ensure proper airflow around both the indoor and outdoor units.
- Schedule regular maintenance with a qualified technician.
