The installation of the outdoor unit is a crucial step in the overall process of installing an HVAC system. It is recommended that you hire a qualified HVAC technician to handle this task. However, if you are comfortable working with electrical and refrigerant systems, you may be able to install the outdoor unit yourself. Here are the steps involved in installing the outdoor unit:
The outdoor unit should be placed on a level surface that is well-drained. It should also be located at least 2 feet away from any walls or other obstructions. The unit should be easily accessible for servicing.
A concrete pad is used to support the outdoor unit. It is typically 4 inches thick and 24 inches square. The pad should be level and be properly anchored to the ground.
Once the pad is in place, the outdoor unit can be placed on top of it. The unit should be leveled and secured to the pad using bolts.
The refrigerant lines are connected to the outdoor unit. The lines should be flared at the ends and sealed with thread sealant. The refrigerant lines should be routed so that they are protected from damage.
The electrical wiring should be connected to the outdoor unit. The wiring should be properly sized and protected from damage. A weatherproof disconnect switch should be installed near the unit.
Once the refrigerant lines and electrical wiring are connected, the system can be charged with refrigerant. The refrigerant charge should be in accordance with the manufacturer's specifications.
Once the system is charged, it should be tested to ensure that it is operating properly. The technician will check the refrigerant pressure, the electrical current, and the airflow. The system should be allowed to run for at least 30 minutes to ensure that it is operating properly.
