English

•

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.

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

(1)

GWP = global warming potential

Please fill in with indelible ink,

■

the factory refrigerant charge of the product,

■

the additional refrigerant amount charged in the field and

■

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 REYQ18-48P system is
multi outdoor unit system, which are only composed of REMQ8-
16P outdoor units. With a multi system combining up to three out-
door units, rated cooling capacity from 50.4kW to 135kW and
rated heating capacity from 56.5kW to 150 kW 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.
