SELECTION OF LOCATION
Select a location for installation that meets the following conditions
and get the customer’s permission.
(1)
There is no danger of fire due to leakage of inflammable gas.
(2)
Select the location of the unit in such a way that neither the dis-
charged air nor the sound generated by the unit disturb anyone.
(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
generally 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 a snowbreak hood (sold separately) is mounted, secure the
required space of installation including the outer dimensions of
the product and snowbreak hood.
•
If the work conditions in figure 2 do not apply, contact your dealer
or Daikin directly.

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 dis-
tances 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.

When installing in a locations where there is heavy snowfall,
implement the following snow measures.
•
Install the outdoor unit and function unit on a mount (pro-
cured locally) so that they may not be buried or covered
with snowfall while the bottom frame will be 200 to 300 mm
higher than the surface of the deposited snow.
•
Mount the snowbreak hood (sold separately) and dismount
the rear suction grille (see fig. 3).
(3)
When mounting the snowbreak hood (sold separately) to
the air inlet, make sure that the air outlet of the snow protec-
tion food will be located right angles to the winter wind or in
the leeward direction.
(4)
If the outdoor temperature of the place of installation is low
in winter and defrost water discharged from the system
freezes while the system is in defrost operation in heating
mode, provide a sufficient space between the bottom frame
of the outdoor unit and the foundation side. (A space of 500
to 1000 mm is recommended.)
(5)
If condensate may drip on downstairs (or walkway) depend-
ing on the floor condition, take a measure such as the instal-
lation of drain pan (field supply).
(6)
The refrigerant R410A itself is nontoxic, nonflammable and is
safe. If the refrigerant should leak however, its concentration
may exceed the allowable limit depending on room size. Due to
this it could be necessary to take measures against leakage.
See “
12. CAUTION FOR REFRIGERANT LEAKS
” for details.

INSPECTING AND HANDLING THE UNIT
•
At delivery, the package should be checked and any damage
should be reported immediately to the carrier claims agent.
•
When handling the unit, take into account the following:
(1)
Fragile, handle the unit with care.
Keep the unit upright in order to avoid compressor damage.
(2)
Decide on the transportation route.
(3)
If hanging the unit, keep the following points in mind and hang the
unit following the procedure shown in figure 4.
•
Use a sling sufficiently strong to hold the mass of the unit.
•
Use 2 sling of at least 8m long.
•
Place extra cloth or boards in the locations where the casing
comes in contact with the sling to prevent damage.
•
Hoist the unit making sure it is being lifted at its center of gravity.
In the case of transporting the outdoor unit by forklift, insert the
fork into the opening (large) under the bottom of the outdoor unit.
(Refer to figure 5)
The function unit is not provided with any opening for fork inser-
tion.
Note
•
Apply a filler cloth on a fork to prevent coating of the bottom frame
from coming off and rust from occurring when bringing the unit
using a forklift.
(4)
After the outdoor unit is installed, remove the transportation
bracket (yellow) by pushing the hook mounted to the opening
(large) of the outdoor unit.
