5. Setup and Installation
Professional installation is recommended for optimal performance and safety. Ensure all local electrical and HVAC codes are followed. The system comes with an installation kit, but specialized tools may be required.
5.1 Unboxing and Component Check
Carefully unbox both the indoor and outdoor units. Verify all components listed in the 'What's in the Box' section are present and undamaged. The indoor unit's mounting plate is pre-installed on the back and needs to be removed before mounting.

5.3 Connecting Refrigerant Lines and Electrical Wiring
Connect the copper refrigerant lines (gas and liquid pipes) between the indoor and outdoor units. Ensure all connections are tight and sealed. Use thread sealant (like Nylo Blue) on flares for a good seal. Connect the communication and power cables according to the wiring diagram in the user manual. Ensure proper grounding.

5.4 Vacuuming the System
After connecting the refrigerant lines, the system must be vacuumed to remove any air and moisture. Connect a vacuum pump and manifold gauges to the service ports. Run the vacuum pump for at least 15 minutes until the gauge reads below -14.5 psi. Hold the vacuum for 30 minutes to ensure no leaks. If the pressure rises, check for leaks and re-vacuum.

5.5 Opening Refrigerant Valves
Once the vacuum test is successful, fully open the liquid and gas valves on the outdoor unit using an Allen wrench. This releases the pre-charged refrigerant into the system. Replace the valve caps securely.
