Caution
•
While following the instructions in this installation manual,
install drain piping to ensure proper drainage and insulate pip-
ing to prevent condensation.
Improper drain piping may result in indoor water leakage and
property damage.
•
Install the indoor, outdoor and function units, power cord and con-
necting 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 possible.
•
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 leak-
age 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.
•
The air conditioner is not intended for use in a potentially explo-
sive atmosphere.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible
to the general public”.
[EMC CHARACTERISTICS]
This 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]
This 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
Take care to keep the system tight when installing.
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.
•
Since R410A is a mixed refrigerant, the required additional refrig-
erant must be charged in its liquid state. (If the system is charged
with refrigerant in its gaseous state, due to composition change,
the system will not function normally.)
Limit by the total maximum refrigerant charge
The total maximum refrigerant charge of a VRV 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,
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
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
Note
•
This manual provides information on the installation of the out-
door unit and function unit. Follow the instructions provided in the
manual and install both the outdoor unit and function unit.
•
For the installation of the indoor unit, refer to the installation man-
ual provided with the indoor unit.
•
Option accessories (sold separately) are required for the installa-
tion of the products. Refer to “
2-6 Option accessory
” for details.
2-1 About product
•
RTSYQ-P series are designed for outdoor installation and used for
cooling and heating aplications. The outdoor system consists of the
RTSQ8-16P outdoor unit and BTSQ20P function unit in combina-
tion.
Only the outdoor unit or function unit cannot be used independently.
Refer to “
2-4 Combination
” for concrete system configurations.
With this system, rated cooling capacity from 28.0kW to 55.9kW
and rated heating capacity from 31.5kW to 62.5kW can be
achieved.
