Cast a solid concrete pad or use heavy-duty rubber riser blocks (e.g., rigid plastic or rubber feet). Ensure the surface is perfectly level. Anchor the unit's feet securely using anchor bolts ( M10cap M 10 ) to prevent movement during high winds or operation. Wall Mounting
Refer to page 18 of the installation manual. Incorrect DIP settings cause addressing conflicts. Use auto-addressing mode unless manual override is required.

Check for hidden damage. If the unit was tilted beyond 30°, let it stand upright for 2 hours before operation.
Always place heavy-duty rubber isolation pads (anti-vibration mounts) beneath the unit's feet to prevent noise transmission into the building structure. Clearance and Airflow Space

If installing in heavy snowfall regions, elevate the unit on a stand higher than the average snow line. If exposed to strong coastal winds, position the unit so the discharge fan does not face directly into the prevailing wind. Minimum Service Clearances
Every outdoor unit has a white sticker with a QR code. Scan it with your smartphone to be taken directly to the manual for that specific serial number range.
Because the contains fluorinated greenhouse gases (R410A with GWP 2088 or R32 with GWP 675 – check your unit), the installation manual explicitly reminds you: Wall Mounting Refer to page 18 of the installation manual
Once piping, evacuation, and wiring are verified, you are ready to power on the system. The Auto-Addressing Process
Strictly observe the physical limits of the multi-split layout: 50 meters Maximum Individual Room Pipe Length: 25 meters
As the installation progresses, you begin the delicate work of laying the "veins." This unit is a heart that pumps life to three separate zones. The manual dictates a precise geometry:
Before charging the system, the refrigerant lines must undergo a nitrogen pressure test (typically at 4.15 MPa) for at least 24 hours to detect leaks. After confirming the system is airtight, a vacuum pump is used to evacuate the lines to a minimum of 500 microns. This step is vital to remove moisture and non-condensable gases, which can cause compressor failure or reduced cooling efficiency. Final Commissioning
Note: Never splice communication cables, as this introduces signal noise that disrupts inverter frequency modulation. Step 5: Evacuation and Leak Testing
