Installation Space Examples
• The installation space requirement shown in the following figure is
a reference for cooling operation when the outdoor temperature is
32°C.
If the design outdoor temperature exceeds 32°C or the heat load
exceeds maximum capacity in all the outdoor unit, take an even
large space on the intake shown in the following figure.
• During installation, install the units using the most appropriate of
the patterns shown in the following figure for the location in
question, taking into consideration human traffic and wind.
• If the number of units installed is more than that shown in the
pattern in the following figure, install the units so there are no short
circuits.
• As regards space in front of the unit, consider the space needed for
the local refrigerant piping when installing the units.
• If the work conditions in the following figure do not apply, contact
your dealer or Daikin directly.
Note
The black arrow indicates the suction side of the outdoor units.

NOTE) For patterns 1 and 2
• Wall height for front side no higher than 1500 mm.
• Wall height on the suction side no higher than 500 mm.
• Wall height for sides – no limit
• Make sure each unit is installed level.
• Install the slave unit adjacent to the master unit.
• Make sure the slave unit faces the same direction as the master
unit.

• Provide enough space for maintaining and servicing the units.
• Provide adequate space for the air in- and outlets.
• Make sure the total length of the gas piping between the
outdoor unit and the outdoor unit multi-connection piping kit is
c
C
≤10 m.
• If the height is exceeded the above, calculate h1 and h2 shown
in the figure below, and add h1/2 to the service space of front
side and h2/2 to the service space of suction side.
