Selection Of Location - Daikin RXYN10AY1 Installation Manual

• The sleeve flare processing of pipes with a diameter of 15.9 mm
is difficult. Use the following socket as an optional accessory to
connect pipes.
Socket BHFN5A10S Connection with 15.9 dia. in size
Note
Be sure to use piping materials withstanding a pressure of
12.3 MPa.
• Use a different elbow sold as an optional accessory if the bending
radius needs to be reduced. This is particularly important for the
bending portions of pipes with a diameter of 15.9 mm.

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 the following figure is
a reference 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 the following figure.
• During installation, install the units using the most appropriate of
the patterns shown in the following figure for the location in ques-
tion, taking into consideration human traffic and wind.
• If the number of units installed is more than that shown in the pat-
tern in the following figure, 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 the following figure do not apply, contact
your dealer or Daikin directly.

• 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.

1.
An inverter air conditioner may cause electronic noise generated
from AM broadcasting. Examine where to install the main air con-
ditioner 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.
If condensate may drip on downstairs (or walkway) depending on
the floor condition, take a measure such as the installation of cen-
tral drain pan kit (sold separately).
