•
The indoor and BS unit should be installed as far away from fluo-
rescent lighting as possible.
Remote controller (wireless kit) transmitting distance can result
shorter than expected in rooms with electronic fluorescent lamps
(inverter or rapid start types).
•
Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an oil spray or vapor is produced,
for example in a kitchen.
Plastic parts may deteriorate and fall off or result in water leakage.
(b) where corrosive gas, such as sulfurous acid gas, is produced.
Corroding copper pipes or soldered parts may result in refrig-
erant leakage.
(c) near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the con-
trol system and result in a malfunction of the unit.
(d) where flammable gas may leak, where there are carbon fiber
or ignitable dust suspensions in the air, or where volatile flam-
mables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
(e) Locations where small animals might build nests inside the unit.
If small animals enter and come in contact with electrical parts,
this can cause malfunctions, smoke, and fire.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible
to the general public”.
[EMC CHARACTERISTICS]
VRV
III
System is a class A product. In a domestic environment this
product may cause radio interference in which case the user may be
required to take adequate measures.
[REFRIGERANT]
VRV
III
System use R410A refrigerant.
•
The refrigerant R410A requires strict cautions for keeping the sys-
tem clean, dry and tight.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
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 refrig-
erant 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.
Limit by the total maximum refrigerant charge
The total maximum refrigerant charge of a VRV
III
system must be
below 100kg, this to be in accordance with CE requirement
(EN60335-2-40 standard).
This means that in case the total maximum refrigerant charge of the
system (factory and additional charge) is equal to or more than
100kg you must divide your multiple outdoor system into smaller
independent systems, each containing less than 100kg refrigerant
charge.
For factory charge, refer to the unit name plate.
Important information regarding the refrigerant used
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do not vent gases into the atmosphere.
Refrigerant type : R410A
GWP
(1)
value : 1975

GWP = global warming potential
Please fill in with indelible ink,
Q
the factory refrigerant charge of the product,
Q
the additional refrigerant amount charged in the field and
Q
+
the total refrigerant charge on the refrigerant charge label
supplied with the product.
The filled out label must be adhered in the proximity of the product
charging port (e.g. onto the inside of the service cover).
(2)
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]
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, oil and eventual
other parts, should be done in accordance with the relevant local and
national regulations.

INTRODUCTION
•
REYQ-P series are designed for outdoor installation and used for
cooling and heating aplications. The REYQ8-16P system is exclu-
sive unit for single outdoor unit system. The unit can not use for
independent unit of multi outdoor unit system.
With this system, rated cooling capacity from 22.4kW to 45.0kW
and rated heating capacity from 25.0kW to 50.0kW can be
achieved.
•
The BS units that combined with REYQ-P system for changing
the refrigerant flow to indoor units are BSVQ100, 160, 250P type
only. To combine with other type BS unit will cause malfunction.
•
The indoor units that combined with REYQ-P system for air con-
ditioning 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.
2-1 Combination
•
The indoor units can be installed in the following range.
〈
Outdoor unit
〉
〈
Total capacity of indoor units
〉
REYQ8PY1 .........................................100
~ 260
REYQ10PY1 .......................................125

REYQ14PY1 .......................................175
~ 455
REYQ16PY1 .......................................200
~ 520
•
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.
