Start PATTERN 2
Calculate the total floor area.
(A = A
total roomA
See table 1:
Is the total floor area
(Atotal) large enough for the given refrigerant
charge and the given
release height?
You CANNOT install the unit in the room.
Place unit in a larger room or higher position
(see table 2 to select adequate release height)
Tables for PATTERN 1 and 2
Table 1: Minimum floor area
Take the following into account:
• For intermediate floor areas, use the column with the lower value. Example: If the floor area is 1.7 m², use the
column of 1.65 m².
• For intermediate refrigerant charges, use the row with the higher value. Example: If the refrigerant charge is
2.35 kg, use the row of 2.4 kg.
