A. Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or
moisture) should be prevented from getting mixed into the system.
B. Tight
Take care to keep the system tight when installing.
R410A does not contain any chlorine, does not destroy the ozone
layer, and does not reduce the earth’s protection against harmful
ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is
released.
•
Since R410A is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state. If the refrigerant is charged in a state
of gas, its composition changes and the system will not work properly.
[DESIGN PRESSURE]
Since design pressure is 478 psi, 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, oil and eventual
other parts, should be done in accordance with the relevant local and
national regulations.

INTRODUCTION
•
RXYQ-P series are designed for outdoor installation and used for
cooling and heating applications.
•
The indoor units that combined with RXYQ-P system for air condi-
tioning are Daikin VRV series indoor units that compatible with
R410A. To learn which indoor units are compatible with R410A, refer
to the product catalogs. To combine with other refrigerant indoor unit
will cause malfunction.

•
For installing the 2 units multi system, Outside unit multi connection
piping kit "BHFP22P100U" are required.
•
If the total capacity of the connected indoor units exceeds the capac-
ity of the outside unit, cooling and heating performance may drop
when running the indoor units. See the capacity table in the Engi-
neering Data Book for details.
2-2 Standard supplied accessories
Confirm the following accessories are included. The storage location of
the accessories is shown in figure 1.
NOTE
Do not throw away any of the accessories until installation is complete.
They are needed for installation work.

2-3 Option accessory
To install the outside units, the following optional parts are also required.
To select an optimum kit, refer to “
6. REFRIGERANT PIPING
”.
•
Outside unit multi connection piping kit
•
Refrigerant branching kit
Make sure that any separately purchased accessories are designed for
use with R410A.
2-4 Technical and Electrical specifications
Refer to the Engineering Data Book for the complete list of specifications.
2-5 Main components
For main components and function of the main components, refer to the
Engineering Data Book.
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 dis-
charged 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 outside 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 gener-
ally 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 mini-
mum space for air inlet and air outlet is available.
(See the
“Installation Space Examples”
for the minimum space
requirements.)
