SELECTION OF LOCATION
Select a location for installation that meets the following conditions.
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 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 3 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 3.
•
During installation, install the units using the most appropriate of
the patterns shown in figure 3 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 3, 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 3 do not apply, contact your dealer
or Daikin directly.

Service space of front side
4.
Service space of suction side
For Patterns 1 and 2 in figure 3:
•
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 h1/2 to the service space of front
side and h2/2 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.
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).
4.
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 “14. 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 a forklift is to be used, insert forks into the opening of the skid
under the unit.
(Refer to figure 5)
4.
If hanging the unit, use a cloth sling to prevent damaging the unit.
Keeping the following points in mind, hang the unit following the
procedure shown in figure 6.
•
Use a sling sufficiently strong to hold the mass of the unit.
•
Use 2 belts 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.
5.
After installation, remove the transportation clasp attached to the
large openings.

Note
Apply a filler cloth on a fork to prevent coating of the bottom frame
from coming off and rust from occurring when bringing in the unit with
anti-corrosion treatment type using a forklift.
5.
PLACING THE UNIT
•
Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise.
(Refer to figure 7)
•
The base should be bigger around than the width of the unit’s legs
(66 mm), and should support the unit.
(Refer to figure 8)
If protective rubber is to be attached, attach it to the whole face of
the base.
•
The height of the base should be at least 150mm from the floor.
•
Secure the unit to its base using foundation bolts. (Use four com-
mercially available M12-type foundation bolts, nuts, and washers.)
•
The foundation bolts should be inserted 20 mm.
(Refer to figure 7)
1.
Unit can not be supported with the
independent footing in four corners
only.
2, 3.
Make sure to install on the base that faces four corners
and centers of the unit.

Note
•
There are restrictions on the refrigerant pipe connecting order
between outdoor unit in the case of the multi system.
See the Note in “2-1 Combination” for detail.
•
When installing on a roof, make sure the roof floor is strong
enough and be sure to water-proof all work.
•
Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
Drain water is sometimes discharged from the outdoor unit when
it is running.
