3.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
4.
The piping length between the outdoor unit and the indoor unit
may not exceed the allowable piping length.
(Refer to "6. REFRIGERANT PIPING")
5.
Locations where the unit's suction vent and outlet vent do not gen-
erally face the wind.
Wind blowing directly into the suction or outlet vents will interfere
with the unit's operation.
If necessary, install some kind of obstruction to block the wind.
6.
The space around the unit is adequate for servicing and the min-
imum space for air inlet and air outlet is available.
(See the "Installation Space Examples" for the minimum space
requirements.)
Installation Space Examples
• The installation space requirement shown in figure 2 is a refer-
ence for cooling operation when the outdoor temperature is 35°C.
If the design outdoor temperature exceeds 35°C or the heat load
exceeds maximum capacity in all the outdoor unit, take an even
large space on the intake shown in figure 2.
• During installation, install the units using the most appropriate of
the patterns shown in figure 2 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 pat-
tern in figure 2, 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 figure 2 do not apply, contact your dealer
or Daikin directly.
(Refer to figure 2)
1. Front side
2. No limit to wall height
3. Service space of front side
4. Service space of suction side
For Patterns 1 and 2 in figure 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.
• If the height is exceeded the above, calculate h1 and h2 shown
in the figure below, and add h2/2 to the service space of front
side and h1/2 to the service space of suction side.

Note
1.
An inverter air conditioner may cause electronic noise gener-
ated from AM broadcasting. Examine where to install the main
air conditioner and electric wires, keeping proper distances
away from stereo equipment, personal computers, etc.
Particularly for locations with weak reception, ensure there is a
distance of at least 3 meters for indoor remote controllers,
place power wiring and transmission wiring in conduits, and
ground the conduits.

2. Branch switch, overcurrent breaker
3. Remote controller
4. COOL/HEAT selector
5. Personal computer or radio
2.
When installing in a locations where there is heavy snowfall,
implement the following snow measures.
• Ensure the base is high enough that intakes are not clogged
by snow.
• Remove the rear intake grille to prevent snow from accumu-
lating on the fins.
3.
If condensate may drip on downstairs (or walkway) depending
on the floor condition, take a measure such as the installation of
central drain pan kit (sold separately).
