Proper installation of the NORTEK RSA3ME4M1 Split System Air Conditioner is crucial for its safe and efficient operation. Here are the steps to follow for installation:
1. Calculate the cooling load of the area to be conditioned and select a system of the appropriate capacity.
2. Check the electrical supply and ensure it is adequate for the unit's operation.
3. Install the indoor section (air handler, furnace, etc.) before routing the refrigerant tubing.
4. Inspect the unit for any damage upon arrival and file a claim with the carrier if necessary.
5. Determine the best location for mounting the outdoor unit, ensuring sufficient clearance for airflow and avoiding obstructions.
6. Install the unit on a solid base, level it, and provide proper clearance from the ground or roof.
7. Connect the refrigerant tubing between the indoor and outdoor units, following sound installation practices.
8. Install a filter dryer in the liquid line and any optional equipment according to the manufacturer's instructions.
9. Complete all brazing operations, ensuring the components are properly cooled before replacing seals, Schrader cores, and caps.
10. Make all electrical connections in compliance with local codes and ordinances, using copper wire and proper conduit.
11. Ground the unit using the grounding lug provided in the control box.
12. Connect the thermostat and low voltage wiring according to the instructions supplied with the thermostat and indoor equipment.
13. Perform a pre-start checklist to verify that all installation steps have been completed correctly.
14. Start up the unit by setting the thermostat to the appropriate mode (cooling or heating) and gradually adjusting the temperature setpoint.
15. Verify proper air circulation by checking the blower operation and adjusting register openings for balanced air distribution.
16. Monitor the system's cooling or heating performance, checking the refrigerant pressures and ensuring the fan and compressor cycle off with the thermostat.
17. Perform routine maintenance, including inspecting and cleaning or replacing air filters, inspecting condensate drains and outdoor coil, and inspecting electrical connections.
18. Follow proper procedures for refrigerant charging, weighing in the recommended additional charge amounts and adjusting the charge to match the superheat or subcooling targets.
19. Refer to the wiring diagrams provided in the manual for any electrical troubleshooting or repairs.
