(c) Actual number of units depends on the indoor unit type (VRV DX, Hydrobox,
RA DX, ...) and the connection ratio restriction for the system (50%
≤
CR
≤
130%).

(e) Sound values are measured in a semi-anechoic room.
(f) Sound power level is an absolute value that a sound generates.
(g) Sound pressure level is a relative value depending on the distance and acoustic
environment. For more details, refer to sound level drawings in the technical data
book.
