3. SELECTION OF LOCATION
Select a location for installation that meets the following conditions
and get the customer's permission.
1.
Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb anyone.
2.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
3.
The piping length between the outdoor unit and the indoor unit may
not exceed the allowable piping length.
(Refer to "6. REFRIGERANT PIPING")
4.
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.
5.
The space around the unit is adequate for servicing and the
minimum 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 reference
for cooling operation when the outdoor temperature is 95°F.
If the design outdoor temperature exceeds 95°F 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
pattern 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 59 in.
• Wall height on the suction side – no higher than 19-5/8 in.
• 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.

DANGER
• Do not install unit in an area where flammable materials are
present due to risk of explosion resulting in serious injury
or death.
• Refrigerant gas in heavier air and replaces oxygen. A massive
leak could lead to oxygen depletion, especially in basements,
and an asphyxiation hazard could occur leading to serious
injury or death.
Refer to the chapter "CAUTION FOR REFRIGERANT LEAKS".

NOTE
1.
An inverter air conditioner may cause electronic noise generated
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 10 ft for indoor remote controllers, place power
wiring and transmission wiring in conduits, and ground the
conduits.

5. Personal computer or radio
2.
When installing in 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
accumulating on the fins.
4. 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, pass the forklift arms through the large
openings on the bottom of the unit. (Refer to figure 4)
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 5.
• Use a sling sufficiently strong to hold the mass of the unit.
• Use 2 belts of at least 27 ft 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 (yellow)
attached to the large openings. (Refer to figure 4)

2. Forklift
(Refer to figure 5)
1. Belt sling
2. Wear plate
5. PLACING THE UNIT
• Make sure the unit is installed level on a sufficiently strong base to
prevent vibration and noise. (Refer to figure 6)
• The base should support the unit with the extent larger than
hatched area in figure 7.
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 5-7/8 in. from the floor.
• Secure the unit to its base using foundation bolts. (Use four
commercially available M12-type foundation bolts, nuts, and
washers.)
• The foundation bolts should be inserted 13/16 in..
