4. Configurazione e installazione
Installation of the Gree Multi21+ system requires specialized knowledge and tools. It must be performed by a state-licensed HVAC contractor to ensure proper function, safety, and warranty validity.
- Selezione del sito: The outdoor unit should be placed on a stable, level surface with adequate clearance for airflow and maintenance. Indoor units are designed for concealed installation within ceiling or wall cavities.
- Set di linee: The system requires 1/4" x 1/2" line sets (two sets for this dual-zone configuration) to connect the indoor units to the outdoor unit. These are not included and must be purchased separately.
- Cavi elettrici: All electrical connections must comply with local codes and be performed by a qualified electrician. The system operates on 208/230V.
- Condotti: Proper duct sizing and installation are critical for efficient air distribution from the concealed indoor units.
- Drenaggio della condensa: Ensure proper drainage for condensate produced by the indoor units to prevent water damage.
5. Istruzioni per l'uso
Your Gree Multi21+ system provides efficient heating and cooling. Each indoor unit is controlled independently via its dedicated remote controller.
- Accensione/spegnimento: Use the 'On/Off' button on the remote to start or stop the unit.
- Selezione della modalità: Select 'Cool' for air conditioning or 'Heat' for heating using the 'Mode' button. Other modes like 'Fan' or 'Dry' may also be available.
- Regolazione della temperatura: Use the temperature up/down buttons to set your desired temperature. The G10 inverter technology maintains steady room temperature by adjusting compressor speed.
- Velocità della ventola: Adjust the fan speed (Low, Medium, High, Auto) to control airflow and noise levels. The system is designed for quiet operation.
- Funzione timer: Program the unit to turn on or off at specific times using the 'Timer' function.
