In case of multiple outdoor systems, only 1 label must be adhered,
mentioning the total factory refrigerant charge of all outdoor units
connected on the refrigerant system.
[DESIGN PRESSURE]
• As the design pressure for local connection piping (suction·HP/LP
gas pipe, gas pipe, and liquid pipe) is at least 3.3 MPa, it is possi-
ble to use existing piping (design pressure of at least 3.3 MPa) but
refer to "6. REFRIGERANT PIPING" and check that existing pip-
ing (including branch piping) is compatible with this unit in terms
of materials and thickness and that it does not appear to be cor-
roded.
Air tight test (3.3 MPa 24/h) to check the strength of existing piping
and that it has no gas leaks.
If it is not possible to perform a pressure test, place existing piping
with piping rated at least 3.3 MPa.
• Check that there has been no compressor malfunction, gas sup-
ply exhaustion, or similar issues that could be attributable to pipe
problems in the past. If there have been any such problems,
check that appropriate repairs were made, and if not, implement
such repairs.
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.

INTRODUCTION
• VRV
III
-Q series are designed for outdoor installation and used for
cooling and heat pump applications. Outdoor units come in three
standard sizes, and with a single system through a multi system
combining up to three outdoor units (Heat Pump series), and up
to four outdoor units (Heat Recovery series). Rated capacity is
below.
RQ(C)YQ: Cooling 14.0~54.0 kW, Heating 16.0~60.0 kW
RQCEQ: Cooling 28.0~84.8 kW, Heating 32.0~89.6 kW
• The BS units that combined with RQCEQ system for changing the
refrigerant flow to indoor units are A type (BSQ-AV1, BS1Q-
A7V1B, BS-Q14AV1) and P type (BSVQ-P, BSV-Q100P) only.
Combination with A type and P type cause malfunction.
• The VRV units can be combined with Daikin VRV series indoor
units for air conditioning purposes. Always use appropriate indoor
units compatible with R410A. To learn which models of indoor
units are compatible with R410A, refer to the product catalogs.
Combination with other indoor refrigerant units will cause malfunc-
tion.

Note
• Be sure to connect an R410A indoor unit.
See the catalog for indoor unit models which can be connected.
• Above is the total capacity and total number of units of the indoor
units when configured in a standard combination. See the techni-
cal reference for details on total capacity and total number of
indoor units when using a configuration other than the standard
combination. The standard combinations are as follows.

Note
• Combinations other than those above are prohibited.
• If the total capacity of the connected indoor units exceeds the
capacity of the outdoor unit, cooling and heating performance
may drop when running the indoor units. See the capacity table in
the Engineering Data Book for details.
• There are restrictions on the refrigerant pipe connecting order
between outdoor unit in the case of the multi system.
Install so that the following restrictions are satisfied.
<Restrictions>
