CAUTION
The use of refrigerant lines that have already been used
can lead to damage to the unit.
▪ Do not reuse a refrigerant line that has been used with
another refrigerant. Replace or carefully clean the refri-
gerant line.
▪ If the total refrigerant charge in the system is < 1.84 kg, there are
no further requirements.
▪ f the total refrigerant charge in the system is ≥ 1.84 kg, other min-
imum floor space requirements must be met:

3 Calculate coolant quantity (dm) exceeding m
4 Calculate the minimum opening range (VA
tion between the installation room and the adjacent room (see ).
5 The device can be installed if:
– 2 ventilation openings are provided between the installation
room and adjacent room (1 each at top and bottom)
– Bottom opening: The bottom opening must meet the require-
ments for the minimum opening range (VA
close to the ground as possible. If the ventilation opening
starts on the floor, the height ≥ must be 20 mm. The bottom
of the opening must be ≤ 100 mm above the floor. At least
50% of the required opening area must be < 200 mm from
the floor. The entire area of the opening must be < 300 mm
from the floor.
– Upper opening: The area of the upper opening must be lar-
ger or the same size as the lower opening. The bottom of
the upper opening must be at least 1.5 m above the top
edge of the lower opening.
– Ventilation openings to the outside are not considered suit-
able ventilation openings.
