RXYQQ8~20T7Y1B
VRV IV System Air Conditioner
4P345099-1 – 2013.04
4 Calculate the refrigerant density taking the volume of the room
where the indoor unit is installed and the adjacent room.
Install ventilation openings in the door of adjacent rooms until
the refrigerant density is smaller than the maximum
concentration level.
19. Disposal requirements
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
20. Unit specifications
20.1. General technical specifications
INFORMATION
For technical and electrical details of multi unit
combinations, see technical engineering data.

(a) Nominal cooling capacities are based on indoor temperature 27°C DB and
19°C WB, outdoor temperature 35°C DB, equivalent refrigerant piping: 5 m, level
difference: 0 m.
(b) Nominal cooling capacities are based on indoor temperature 20°C DB, outdoor
temperature 7°C DB and 6°C WB, equivalent refrigerant piping: 5 m, level
difference: 0 m.
(c) Actual number of units depends on the connection ratio restriction for the system
(50%≤CR≤130%).
(d) Nominal at 230 V.
(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.
