6. Position Outdoor Condenser: Place the outdoor condenser unit in its designated location.
7. Connect Linesets: Connect the unit lineset to the condenser lineset and tighten firmly. If available, use a digital torque wrench to ensure proper tightening.
8. Connexions elèctriques: Ensure all power sources are turned off. Remove the electrical compartment cover. Connect the numbered wires from the indoor unit to the corresponding numbered terminals on the outdoor condenser's electrical block. Connect the ground wire (green to green). Connect the power cables (black to 'N', red to 'L') to the condenser.
9. Vacuuming the System: Ensure you have appropriate vacuum equipment. Connect the hose from the outdoor condenser unit to the gauge, and the hose from the vacuum to the gauge. Open valves on the gauge and turn the vacuum on. Monitor the micron reading closely and close valves once it reaches 350. Turn off the vacuum pump.
10. Activate Refrigerant Flow: Restore power to the outlet. Turn the mini split unit on and set it to the lowest cold setting. Allow a few minutes for the outdoor condenser fan to start. Use a service wrench to gradually open the high side (top valve). Monitor the gauge as numbers will drop into the negative range. After opening the high side valve, quickly open the low side (bottom valve). The gauge readings will increase, which is expected.
