1. Site Inspection:

   • A qualified technician inspects the location where the indoor and outdoor units will be installed.
   • Ensures there is proper airflow and ventilation and that the space is free of obstacles.
   • Verifies the distance between the indoor and outdoor units and confirms that it meets manufacturer specifications.
   • Checks the power supply and makes sure the electrical connection is safe and meets local standards.

2. Indoor Unit Installation:

   • Mounting the indoor unit on a wall using a bracket, ensuring it is level and secure.
   • Drilling holes for the refrigerant pipe, drainage pipe, and electrical wires.
   • Installing a drainage system (PVC pipe) for condensation water.
   • Connecting the refrigerant line (copper piping) from the outdoor unit to the indoor unit.
   • Connecting electrical wiring from the indoor unit to the power supply.
   • Checking the indoor unit’s position to ensure proper air distribution.

3. Outdoor Unit Installation:

   • Mounting the outdoor unit on a flat surface or bracket (on the ground, wall, or roof, depending on the location).
   • Ensuring the unit is level and positioned to avoid obstruction to airflow.
   • Connecting the refrigerant piping from the indoor unit to the outdoor unit.
   • Installing electrical connections to the outdoor unit.
   • Ensuring proper clearance around the outdoor unit for optimal performance.

4. Refrigerant Piping:

   • Cutting and bending the copper pipes to the required lengths and connecting them between the indoor and outdoor units.
   • Insulating the refrigerant piping to prevent energy loss.
   • Tightening the connections to avoid leaks and ensuring proper sealing.

5. Electrical Connections:

   • Connecting the power supply to the indoor and outdoor units.
   • Ensuring proper grounding for safety.
   • Checking the electrical connections with a multimeter to ensure no short circuits.

6. Vacuuming and Leak Testing:

   • Using a vacuum pump to remove air and moisture from the refrigerant lines.
   • Conducting a leak test by pressurizing the system to ensure there are no leaks in the pipes or connections.
   • Once the leak test is successful, the refrigerant is charged into the system.

7. System Startup and Testing:

   • Starting the system and checking the cooling performance.
   • Verifying that the system is cooling effectively and there is no abnormal noise or vibration.
   • Ensuring the thermostat and remote control are functioning properly.
   • Checking for any unusual odors or issues in the system.

8. Final Inspection and Clean-up:

   • Making sure all units are properly mounted and aligned.
   • Cleaning the area of any debris or dust from the installation process.
   • Providing the customer with a manual and instructions on how to operate and maintain the AC unit.

Materials Used in Split AC Installation:

1. Indoor Unit:

   • Wall-mounted split air conditioner unit (includes evaporator coil, fan, and air filter).
   • Mounting bracket for the indoor unit.
   • Insulated refrigerant pipes (copper tubing).
   • Condensate drainage pipe (usually PVC or flexible tubing).
   • Electrical wiring (for power supply and controls).
   • Remote control for the air conditioner.
   • Screws, anchors, and other hardware for mounting.

2. Outdoor Unit:

   • Outdoor condenser unit (includes compressor, condenser coil, and fan).
   • Mounting bracket or stand (for wall, ground, or roof mounting).
   • Insulated refrigerant pipes (copper tubing).
   • Electrical wiring for the outdoor unit.
   • Grounding cable for safety.
   • Screws, bolts, and other hardware for securing the unit.

3. Refrigerant System Components:

   • Copper refrigerant pipes (for carrying refrigerant between indoor and outdoor units).
   • Refrigerant gas (R-22, R-410A, or R-32, depending on the model).
   • Insulation material (for refrigerant pipes).
   • Pipe connectors and fittings (e.g., flare nuts, elbows, T-joints).
   • Valve (for charging and servicing the refrigerant).

4. Tools and Equipment:

   • Vacuum pump (for evacuating air and moisture from the refrigerant lines).
   • Pressure gauge and manifold (for leak testing and refrigerant charging).
   • Pipe cutter and bender (for refrigerant piping).
   • Drill with bits (for making holes in the wall for pipes).
   • Wrench and screwdrivers (for tightening connections).
   • Level (to ensure proper installation alignment).
   • Multimeter (for electrical testing).

5. Miscellaneous:

   • PVC piping and fittings (for condensate drainage).
   • Electrical junction box and fuses (for electrical connections).
   • Silicone sealant or weatherproof tape (for sealing holes and preventing leaks).
   • Insulation material for pipes (such as rubber or foam).

Proper installation ensures efficient operation, longevity, and safety of the split air conditioning system.
