3. Opsætning og installation
Important: This system mandates professional installation. It is not a DIY mini split AC. Improper installation can lead to system malfunction, voided warranty, and safety hazards.
Overvejelser før installation:
- Ensure the installation area meets the required clearances for both indoor and outdoor units.
- Verify power supply requirements (208-230V) and ensure a dedicated circuit with a maximum fuse size of 15A.
- The unit is pre-charged with refrigerant. However, line-set vacuuming is required during installation. Any alteration of line-set length requires adjusting freon levels by a certified technician.
Installation Steps (Professional Guidance Required):
- Montering af indendørsenheden: Secure the mounting plate to the wall, ensuring it is level and at the correct height.
- Drilling the Wall Hole: Create a hole for the refrigerant pipes, drain line, and communication cable.
- Connecting Piping and Wiring: Connect the refrigerant pipes, drain line, and electrical wiring between the indoor and outdoor units. Ensure all connections are secure and leak-free.
- Vacuuming the Line Set: A vacuum pump must be used to remove air and moisture from the refrigerant lines. This is critical for system performance and longevity.
- Montering af udendørsenheden: Place the outdoor unit on a stable, level surface using the provided rubber feet to reduce vibration.
- Leak Check and Test Run: After all connections are made, perform a leak check and then a test run to ensure proper operation in all modes.
