5.
The space around the unit is adequate for servicing and the mini-
mum 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 outside 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 inju-
ry 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 condi-
tioner and electric wires, keeping proper distances away from stereo
equipment, personal computers, etc.
Particularly for locations with weak reception, ensure there is a dis-
tance of at least 10 ft for indoor remote controllers, place power wir-
ing and transmission wiring in conduits, and ground the conduits.

2.
When installing in locations where there is heavy snowfall, imple-
ment 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.

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 open-
ings 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 pro-
cedure 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 brackets (yellow)
attached to the large openings. (Refer to figure 4)

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 commer-
cially available M12-type foundation bolts, nuts, and washers.)
• The foundation bolts should be inserted 13/16 in..

NOTE
• There are restrictions on the refrigerant pipe connecting order
between outside unit in the case of the multi system.
See "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 outside unit when it is
running.
• For anti-corrosion type, use nuts with resin washers. If the paint on
nut connections comes off, the anti-corrosion effect may decrease.
