•

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 pos-
sible.

•

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 mal-
functions, 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 flamma-
bles 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]
VRV

III

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.Tightly sealed

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. Therefore,
sealing tightness is particularly important in installation. Care-
fully read the chapter “REFRIGERANT PIPING” and strictly
observe the correct procedures.

•

Since design pressure is 4.0 MPa or 40 bar (for R407C units: 3.3
MPa or 33 bar), the thickness of pipes must be greater than pre-
viously. Since R410A is a mixed refrigerant, the required addi-
tional refrigerant must be charged in its liquid state. (If the system
is charged with refrigerant in its gaseous state, due to composi-
tion change, the system will not function normally). The indoor
unit is designed for R410A use. See the catalogue for indoor unit
models that can be connected. (Normal operation is not possible
when connecting units that are originally designed for other refrig-
erants.)

Total maximum refrigerant charge limits

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 onsite 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, 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.

INTRODUCTION

•

“VRV

III

-Q” 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 two outdoor units, rated cooling capacity
from 22.4 kW to 118 kW and rated heating capacity from 25.0 kW
to 132 kW can be achieved.

•

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 lean which models of indoor
units are compatible with R410A, refer to the product catalogs.
To combine with other refrigerant indoor unit will cause malfunction.
