(Applies to R(Y)71LU–140LU)
Compactly designed outdoor unit
with interior layout optimised for the
smooth airflow.
The design curved Super Aero
Grille restricts the spread of
exhaust gas and fits in the same
space as conventional outdoor
units.
Slim and low-profile design outdoor units
(Applies to R(Y)71LU–140LU)
The light weight makes delivery and
installation easier.
Reduced weight
(Applies to R(Y)71LU-125LU)
To suppress turbulence and achieve
quiet operation, the curved ribs of the
grille are optimised to meet the
outflow of air.
Fitted with Super Aero Grille
(Applies to R(Y)71LU–140LU)
Smooth running, minimal vibration,
low operating sound.
Equipped with scroll compressor
for quiet operation

P o w e r ful
Uses "Receiver"
to enhance refrigerant control
(Applies to R(Y)71LU–140LU)
Instead of the using an accumulator to ab-
sorb excess refrigerant, Daikin outdoor
units have a receiver in the piping located
away from the compressor. By preventing
the return of liquid to the compressor, the
receiver enhances reliability.
Cooling is efficient even in winter when
indoor temperatures are higher than those
outside, such as in underground public spaces
or offices with many computers.
Suited for year-round cooling
applications
RY200KU and250KU can adapt up to 0°C.
Also adapts to year-round cooling
A pump-down switch is provided to
make it easier to collect refrigerant if
the unit is to be moved or layout
modified.
4-direction piping offers
greater layout freedom
(Applies to R(Y)71LU–140LU)
Facilitates pump down
(Refrigerant recovery function)
Effective gas monitoring reduces the
labor required for operation,
maintenance, and repairs.
Piping can be run from the front,
bottom, right or rear surface
according to how the unit is installed.
Low gas level detection function
(Applies to R(Y)71LU–140LU)
Heat pump/RY71–140LU: possible up to -5°C
Cooling only/R71–140LU: possible up to -15°C
The year-round cooling kit is required as option.
OUTDOOR UNIT
(Applies to all outdoor units)
To achieve increased durability by
improved resistance to salt corrosion
and atmospheric pollution, coated PE
fins (with special acryl pretreatment)
are used for the heat exchanger of the
outdoor unit.

Additional refrigerant charging is required if the
refrigerant pipe is longer than the length.
Allowed refrigerant pipe length and
level difference
To optimise heating performance, by
monitoring the difference in air temperature
in the indoor/outdoor heat exchanger and
the intake air temperature, the system
accurately adjusts to provide the best
operating parameters.
This enables defrost mode to be initiated
and so minimise indoor declines in
temperature caused by frost. For example, if
the outdoor airtemperature falls to -1.5°C,
the integrated heating capacity is raised
about 20%.
RU08/10KU models are factory
shipped with refrigerant charged for
5 m of piping.
RU08/10K models are factory
