Service Space
A6 Duct Type 11
3. Service Space
Ensure enough space required for installation and maintenance.
There is enough space for installation and maintenance. The ceiling is horizontal, and its structure can
endure the weight of the indoor unit. The outlet and the inlet are not impeded, and the influence of external
air is the least. The air flow can reach throughout the room. The connecting pipe and drainpipe could be
extracted out easily. There is no direct radiation from heater.
