English 1
• Install the indoor and outdoor units, power cord and connecting
wires at least 1 meter away from televisions or radios to prevent
picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter
may not be sufficient to eliminate noise.)
• Remote controller (wireless kit) transmitting distance can be
shorter than expected in rooms with electronic fluorescent lamps
(inverter or rapid start types).
Install the indoor unit as far away from fluorescent lamps as possible.
• Make sure to provide for adequate measures in order to prevent
that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the
area around the unit clean.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is pro-
duced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where flammable gas may leak, where there is carbon fibre or
ignitable dust suspensions in the air, or where volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible
to the general public”.
[REFRIGERANT]
VRVIII System use R410A refrigerant.
• The refrigerant R410A requires that strict precautions be
observed for keeping the system clean, dry and tightly sealed.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A.Clean and dry
Strict measures must be taken to keep impurities (including
SUNISO oil and other mineral oils as well as moisture) out of
the system.
B.Tight sealed
Take care to keep the system tight when installing.
R410A contains no chlorine, does not destroy the ozone layer
and so does not reduce the earth’s protection against harmful
ultraviolet radiation.
R410A will contribute only slightly to the greenhouse effect if
released into the atmosphere.
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. (If the system is charged
with refrigerant in its gaseous state, due to composition change,
the system will not function normally.)
[DESIGN PRESSURE]
Since design pressure is 4.0MPa or 40bar (for R407C units: 3.3MPa
or 33bar),the wall thickness of pipes should be more carefully
selected in accordance with the relevant local and national regulations.
1-3 Disposal requirements
Dismantling of the unit, treatment of the refrigerant, of oil and of other
parts must be done in accordance with relevant local and national
legislation.
2. INTRODUCTION
• RXYQ-P series are designed for outdoor installation and used for
cooling and heatpump applications. Outdoor units come in three
standard sizes, and with a single system through a multi system
combining up to three outdoor units, rated cooling capacity from
17.7 kW to 81.6 kW and rated heating capacity from 25.0 kW to
112.5 kW can be achieved.
• The RXYQ-P units can be combined with Daikin VRV series
indoor units for air conditioning purposes. Always use appropriate
indoor units compatible with R410A. To lean which models of
indoor units are compatible with R410A, refer to the product catalogs.

“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 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 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 pattern 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.

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.

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 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 accumulating 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.
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 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. (Refer to figure 6)

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 commercially available M12-type foundation bolts, nuts, and washers.)
•
The foundation bolts should be inserted 20 mm.
(Refer to figure 7)
1. The product cannot be supported
only with four corners.
2. Make sure to use the center supports.

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.
• For anti-corrosion type use nuts with resin washers. If the paint on
nut connections comes off, the anti-corrosion effect may
decrease.

6. REFRIGERANT PIPING
Note
• All field piping must be installed by a licensed refrigeration tech-
nician and must comply with relevant local and national regulations.
• After piping work is complete, do not under any circumstances
open the shutoff valve until “7. FIELD WIRING” and “10. CHECKING OF DEVICE AND INSTALLATION CONDITIONS” are complete.
•
Do not use flux when brazing the refrigerant piping. Use the phosphor copper brazing filler metal
710/795: ISO 3677)
(Flux has extremely harmful influence on refrigerant piping systems. For instance, if the chlorine based flux is used, it will
cause pipe corrosion or, in particular, if the flux contains fluorine, it will damage the refrigerant oil.)
which does not require flux.
6-1 Selection of piping material and Refrigerant
branching kit
• Use only pipes which are clean inside and outside and which do
not accumulate harmful sulfur, oxidants, dirt, cutting oils, moisture, or other contamination. (Foreign materials inside pipes
including oils for fabrication must be 30mg/10m or less.)
• Use the following items for the refrigerant piping.
Material: Jointless phosphor-deoxidized copper pipe
Size: See “6-5 Example of connection” to determine the cor-
rect size.
Thickness: Select a thickness for the refrigerant piping which
complies with national and local laws.
For R410A, the design pressure is 4.0 MPa (40-bar).
The minimum thickness of piping according to Japan’s HighPressure Gas Safety Law (as of January 2003) is shown
below.
Temper grade (O type, 1/2H type) in the table indicate the
material types specified in JIS H 3300.

• For piping work, follow the maximum tolerated length, difference
in height, and length after a branch indicated in the “6-5 Example
of connection”.
• A refrigerant branching kit (sold separately) is needed for piping
branches and connection of piping between outdoor unit (in case
of multi system).
Use only separately sold items selected specifically according to
the refrigerant branch kit selection in the “6-5 Example of con-
nection”.
