Table 3: Maximum chimney length
When installing a chimney, the chimney length must be less than the maximum chimney length.
• Use the columns with the correct refrigerant charge. For intermediate refrigerant charges, use the columns with
the higher value. Example: If the refrigerant charge is 4.0kg, use the columns of 5.8kg.
• For intermediate diameters, use the column with the lower value. Example: If the diameter is 23mm, use the
column of 22mm.
• X: Not allowed
Maximum chimney length (m) – In case of Refrigerant charge=3.8kg (and T=60°C) In case of Refrigerant charge=5.8kg (and T=60°C)

Table 4: Minimum bottom opening area for natural ventilation
Take the following into account:
• Use the correct table. For intermediate refrigerant charges, use the table with the higher value. Example: If the
refrigerant charge is 4.3kg, use the table of 4.8kg.
• For intermediate floor areas, use the column with the lower value. Example: If the floor area is 12.50m², use the
column of 10.00m².
• For intermediate release height values, use the row with the lower value. Example: If the release height is
2.20m, use the row of 2.1m.
