Key Installation Steps (Summary):
- Marking Locations: Use the provided template to mark the locations for the line set wall hole and the mini split bracket.
- Mounting Bracket: Securely attach the mini split bracket to the wall using the provided screws. Ensure the bracket is properly leveled.
- Routing Lines: Route the line set, drain hose, and electrical wiring through the wall opening.
- Mounting Indoor Unit: Securely mount the indoor mini split unit onto the bracket.
- Taping Lines: Tape the drain hose and line sets together for a neat and organized installation.
- Securing Electrical Wires: Use zip ties to secure the electrical wires around the taped line sets and drain hose.
- Positioning Outdoor Condenser: Place the outdoor condenser unit in its designated location.
- Connecting Line Set: Connect the unit line set to the condenser line set and tighten down firmly. Use a digital torque wrench if available to ensure proper tightening according to specifications.
- Electrical Connections: Connect the electrical wires (red, black, green ground) to their corresponding terminals on the condenser unit. Each wire is designated with a specific letter and number.
- Vacuuming the System: Connect a vacuum pump to the system via a gauge. Open the valves on the gauge and activate the vacuum. Monitor the micron reading closely and close the valves once it reaches 350 microns. Turn off the vacuum pump.
- Restoring Power: Restore power to the outdoor unit.
- Initiating Cooling: Turn on the mini split unit and set it to the lowest cold setting. Allow a few minutes for the outdoor condenser fan to initiate.
- Opening Valves: Gradually open the high side (top) valve using a service wrench. Monitor the gauge as readings will decrease into the negative range. After the high side valve is open, promptly open the low side (bottom) valve. Monitor the gauge closely as the readings will increase, which is expected.
