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 3.5 kg, use the columns of 4.05 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=3.25 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 3.5 kg, use the table of 3.65 kg.
•
For intermediate floor areas, use the column with the lower value.
Example:
If the floor area is 7.25 m², use the
column of 6.00 m².
•
For intermediate release height values, use the row with the lower value.
Example:
If the release height is
1.90 m, use the row of 1.86 m.
