| Model | Capacity W (HP) | Max. Refrigerant Charge (kg) | Indoor Amin (m²) |
|---|---|---|---|
| Z20***, XZ20*** | 3/4HP | 0.78 | Not applicable (*) |
| Z25***, XZ25*** | 1.0HP | 0.78 | Not applicable (*) |
| Z35***, XZ35*** | 1.5HP | 0.89 | Not applicable (*) |
| Z42***, XZ42*** | 1.75HP | 0.91 | Not applicable (*) |
| Z50***, XZ50*** | 2.0HP | 1.47 | Not applicable (*) |
| Z71*** | 2.5HP | 1.85 | 4.46 |
(*)Systems with total refrigerant charge, mc , lower than 1.84 kg are not subjected to any room area requirements.
*Table “A” only applicable for single split connection.
*In case of connection to outdoor multi inverter, refer to installation manual at outdoor unit.
Amin = (mc / (2.5 × (LFL)(5/4) × h0))2
**not less than safety factor margin
| Amin | = | Required minimum room area, in m² |
| mc | = | Refrigerant charge in appliance, in kg |
| LFL | = | Lower flammability limit (0.307 kg/m³) |
| h0 | = | Installation height of the appliance (1.8 m for wall mounted) |
| SF | = | Safety factor with a value of 0.75 |
**The required minimum room area, Amin, shall also be governed by the safety factor margin formula below :
Amin = mc / (SF × LFL × h0)
The higher value shall be taken when determining the room area.
