Unit can be installed at room A if:
▪ 2 ventilation openings (permanently open) are provided between room A and B, 1 at the top and 1 at the bottom.
▪ Bottom opening:The bottom opening must meet the minimum area requirements(VA
min
).It must be as close as possible to the floor.If the ventilation
opening starts from the floor, the height must be ≥20mm. The bottom of the opening must be situated≤100mm from the floor. At
least 50% of the required
opening area must be situated <200 mm from the floor. The entire area of the opening must be situated <300 mm from the floor.
▪ Top opening:The area of the top opening must be larger than or equal to the bottom opening. The bottom of the top opening must be situated at least 1.5
m above the top of the bottom opening.
▪ Ventilation openings to the
outside are NOT considered suitable ventilation openings (the user
can block them when it is cold).
