20 Installation
•
Do not use a charging cylinder.
Using a charging cylinder may cause the refrigerant to
deteriorate.
•
Systems using R-410A must be kept clean, dry, and
tightly installed.
A.Clean and dry:
Foreign materials (including mineral oils such as
SUNISO oil or moisture) should be prevented from get-
ting mixed into the system.
B.Tight:
R-410A can contribute slightly to the greenhouse effect
if it is released. Therefore we should take special atten-
tion to check the tightness of the installation.
•
Since R-410A is a mixed refrigerant, the required ad-
ditional refrigerant must be charged in its liquid state.
If the refrigerant is charged in a state of gas, its com-
position changes and the system will not work prop-
erly.
The indoor unit requires R-410A. See the catalog for
indoor unit models that can be connected.
Normal operation is not possible when connected to other
units. that do not use R410-A.
•
In a domestic environment this product may cause radio
interferences that require the user to take precautions.
•
Use precautions to prevent the outdoor unit from be-
ing used as a shelter by small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke, or fire. Please instruct the
customer to keep the area around the unit clean.
Ask your dealer or qualified personnel to carry out instal-
lation work. Do not try to install the unit alone.
Improper installation may result in water leakage, electric
shocks, or fire.
•
Perform installation work in accordance with this in-
stallation manual.
Improper installation may result in water leakage, electric
shocks, or fire.
•
Be sure to use only the specified accessories and
parts for installation work.
Failure to use the specified parts may result in water leak-
age, electric shocks, fire, or the unit falling.
•
Install the unit on a foundation strong enough to with-
stand the weight of the unit.
A foundation of insufficient strength may result in the
equipment falling and causing injuries.
•
Carry out the specified installation work after taking
account of strong winds, typhoons or earthquakes.
Improper installation work may result in the equipment
falling and causing accidents.
•
Make sure that a separate power supply circuit is pro-
vided for this unit and that all electrical work is car-
ried out by qualified personnel according to local
laws and regulations and this installation manual.
An insufficient power supply capacity or improper electri-
cal construction may lead to electric shocks, or fire.
•
Make sure that all wiring is secured, the specified wires are
used, and no external forces act on the terminal connec-
tions or wires.
Improper connections or installation may result in fire.
•
When wiring the power supply and connecting the re-
mote controller wiring and transmission wiring, posi-
tion the wires so that the electric parts box lid can be
securely fastened.
Improper positioning of the electric parts box lid may
result in electric shocks, fire, or the terminals overheat-
ing.
NOTE
•
Install the indoor and outdoor units, power supply
wires and transmission wires at least 3.5 ft. away
from televisions or radios in order to prevent image
interference or noise.
Depending on the radio waves, a distance of 3.5 ft. may
not be enough to eliminate noise.
•
Dismantling of the unit, and treatment of the refriger-
ant, oil, and other parts, should be done in accor-
dance with the relevant local and national
regulations.
•
Do not use the following tools that are used with con-
ventional refrigerants:. Gauge manifold, charge hose,
gas leak detector, reverse flow check valve, refriger-
ant charge base, vacuum gauge, refrigerant recovery
equipment.
If conventional refrigerant and refrigerator oils are mixed
in the R-410A, the refrigerant may deteriorate.
•
Never perform piping connection work for the out-
door unit when it is raining.

INTRODUCTION
This installation manual covers VRV inverters of the Daikin
RXYQ-M series. These units are designed for outdoor instal-
lation and used for cooling and heatpump applications.
The RXYQ-M outdoor units can be combined with Daikin VRV
series indoor units for.
This installation manual describes unpacking, installing, and
connecting RXYQ-M outdoor units. Installation of the indoor
units is not described in this manual. Always refer to the instal-
lation manual supplied with specific units for their installation.
