• Funzionamentu Silenziu Whisper: The AC split unit operates as low as 42dB for minimal disturbance.

2. Informazioni di sicurezza

Installazione prufessiunale necessaria: The air conditioner must be installed by professional personnel to ensure safety, optimal performance, and warranty coverage.

Manipulazione di u refrigerante:

• For units with refrigerant R32 or R454B, ensure both indoor and outdoor units have proper ventilation. Strictly prohibit the operation of open flame in the installation location.
• For units with R410A, R32, or R454B, gas leakage detection must be performed after pipe connection to ensure a leak-free refrigeration system.
• For R410A, R32, or R454B units, the system must be vacuumed to ensure no air is inside.
• If the indoor and outdoor connection pipe exceeds the standard length, extra refrigerant may need to be added. Refer to the service manual for specific quantities based on refrigerant type and model.

Sicurezza elettrica:

• Ensure that indoor and outdoor connection wires and power supply are connected correctly and reliably.
• The AC unit must have a separate leakage breaker.

5. Setup è Installazione

Professional HVAC installation is required for this system. The following steps provide an overview of the installation process. Refer to the detailed service manual for complete instructions.

5.1 Installazione di unità interna

1. Verificazione pre-installazione: Before starting, check the status of both indoor and outdoor units. Verify no parts are broken, the indoor cross-fan operates, and the remote controller functions. If the cross-fan does not operate, check and adjust it first.
2. Gas Flow Check: Verify there is no gas flow from the connector. If gas is detected, check the evaporator for any leakage.
3. Cablaggio Elettricu: Unfix the electric box cover. Connect the indoor and outdoor unit connection wires. Double-check the marks on the wires (1, 2, 3, and ground) to ensure correct and reliable wiring.
4. Piping Direction: Based on the installation location, decide the piping direction and cut the face frame case accordingly. Ensure the cut edges are clean and smooth to prevent damage to the pipes.
5. Cunnette i tubi: Adjust the connection pipes, paying attention to the alignment of the horn. Control the wrench's strength to prevent nut rupture. Ensure no gas leakage after pipe connection.
6. Cunnette u tubu di drenaggiu: Connect the drainage pipe. It must be sealed with electrical tape to ensure no water leakage.
7. Wrap Pipes and Wires: Wrap the refrigerant pipes, drainage hose, and wiring together. Important: Retain the pipe connectors for later leak detection.
8. Installa a placa murale: Install the wall plate, ensuring it is secure enough to hold the indoor unit.
9. Muntà l'unità interna: Pass the pipes through the wall hole. Fix the indoor unit firmly on the mounting plate.

5.2 Installazione di l'unità esterna

1. Fix Outdoor Unit: Fix the outdoor unit on the mounting bracket. It is recommended to use rubbers on the feet to decrease possible vibration and noise.
2. Open Refrigerant Pipes Cover: Open the refrigerant pipes cover on the outdoor unit.
3. Connect Refrigerant Pipes: Connect the refrigerant pipes similar to the indoor unit. Control the force of the wrench to prevent nut breakage. Connect the pipe horn to the 2-way and 3-way valve straightly to prevent gas leakage.
4. Cunnessioni elettriche: Open the electrical control box. The indoor and outdoor connection cable goes to the left hole of the cover, and the power cord to the right hole. Connect the indoor and outdoor connection wires to the electric terminal, paying attention to the marks of 1, 2, 3, and ground on the wires. They must be one-to-one correspondence with the markings on the terminal. Connect the power supply cable to the electric terminal. Ensure all wires are connected correctly and reliably.

5.3 Vacuuming and Leakage Detection

1. Cunnette a pompa di vuoto: Connect one hose from the manifold low pressure gauge to the outdoor unit service port on the three-way valve. Then connect the manifold gauge to the vacuum pump.
2. Sistema di vuoto: Switch on the vacuum pump and open the gauge low pressure valve. For split AC, vacuum the unit for at least 15 minutes until the vacuum gauge is maintained at -14.5 psi. For R32 or R454B units, based on pipe length, vacuum for 15-30 minutes when pump capacity is 4-4.5 CFM.
3. Pressure Hold Test: Close the low pressure valve on the manifold gauge, then switch off the vacuum pump. Hold the pressure for 5 minutes. Ensure the rebound of the compound gauge pointer does not exceed 0.73 psi. If it rebounds more than 0.73 psi, check and repair the leakage point, most likely from the pipe connector.
4. Release Refrigerant: Open the outdoor unit low pressure valve counterclockwise for 1/4 turn with a hexagonal wrench to let a little refrigerant fill the system. Close the low pressure valve after 5 seconds. Check all pipe connectors of indoor and outdoor units for gas leakage. If leakage is found, repair and tighten the connection.
5. Seal Wall Hole: Once no gas leakage is found, clean the connectors and wrap the indoor connector pipes. Seal the wall hole with sealing cement.
6. Remove Pressure Hose: Keep the gauge at positive pressure and quickly remove the pressure hose from the outdoor unit service valve.
7. Reinstall Protective Caps: Reinstall the protective caps of the service port, low pressure, and high pressure valves of the outdoor unit. Reinstall the valves cover.

6. Operating Instructions

After installation, switch on the unit for a running test. The system offers various modes for personalized comfort:
