Cautions for units utilizing refrigerant R410A
1-1. CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
Store the piping indoors, and keep both ends of
the piping sealed until just before brazing.
(Leave elbow joints, etc. in their packaging.)
Avoid using thin pipes.
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
Do not use refrigerant other than R410A.
If other refrigerant (R22, etc.) is used, chlorine in refrige-
rant can cause deterioration of refrigerant oil, etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil, etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Handle tools with care.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigera-
nt will change and the efficiency will be lowered.

Tools for R410A
Contamination inside refrigerant piping can cause deterio-
ration of refrigerant oil, etc.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
If large amount of mineral oil enters, that can cause deterio-
ration of refrigerant oil, etc.
Make sure that the inside and outside of refrige-
rant piping is clean and it has no contaminants
such as sulfur, oxides, dirt, shaving particles, etc,
which are hazard to refrigerant cycle.
In addition, use pipes with specified thickness.
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
Use the specified refrigerant only.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.

[3] Service tools
Use the below service tools as exclusive tools for R410A refrigerant.
[1] Cautions for service
(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) If moisture or foreign matter might have entered the refrigerant piping during service, ensure to remove them.
[2] Additional refrigerant charge
When charging directly from cylinder
(1)CheckthatcylinderforR410Aonthemarketisasyphontype.
(2)Chargingshouldbeperformedwiththecylinderofsyphonstoodvertically.(Refrigerantischargedfromliquidphase.)

Cautions for refrigerant piping work
NewrefrigerantR410Aisadoptedforreplacement inverterseries.Althoughtherefrigerant piping workforR410Aissame
as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working
pressureofR410Ais1.6timeshigherthanthatofR22,theirsizesofflaredsectionsandflarenutsaredifferent.
1Thicknessofpipes
Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness
shownbelow.(Neverusepipesof0.7mmorbelow.)
2Dimensions of flare cutting and flare nut
The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that,
R410Aisarefrigerant,whichhashigherriskofleakagebecauseitsworkingpressureishigherthanthatofotherrefrig-
erants. Therefore, to enhance airtightness and strength, flare cutting dimension of copper pipe for R410A has been
specifiedseparatelyfromthedimensionsforotherrefrigerantsasshownbelow.ThedimensionBofflarenutforR410A
alsohas partly been changed to increase strength as shown below.Set copper pipe correctly referring to copper pipe
flaringdimensionsforR410Abelow.For1/2and5/8inchpipes,thedimensionBchanges.

Total Indoor Units Capacity (CTi)
CTo = Outdoor Rating × Outdoor Design Temperature Correction × Piping Length Correction
= 12.5 × 0.88 × 0.88
= 9.7 kW
(6) Determination of Maximum System Capacity
Comparison of Capacity between Total Indoor Units Capacity (CTi) and Total Outdoor Unit Capacity (CTo)
CTi = 9.9 > CTo = 9.7, thus, select CTo.
CTx = CTo = 9.7 kW
(7) Comparison with Essential Load
Against the essential load 9.0kW, the maximum system capacity is 9.7 kW: Proper outdoor units have been selected.
(8) Calculation of Maximum Indoor Unit Capacity of Each Room
CTx = CTo, thus, calculate by the calculation below
Room1
Maximum Capacity × Room1 Capacity after the Temperature Correction/(Room1,2 Total Capacity after the Temperature Correction
= 9.7 × (4.5 × 1.03)/(4.5 × 1.03 + 5.6 × 0.94)
= 4.5 kW OK: fulfills the load 4.0 kW
Room2
Maximum Capacity × Room2 Capacity after the Temperature Correction/(Room1,2 Total Capacity after the Temperature Correction)
= 9.7 × (5.6 × 0.94)/(4.5 × 1.03 + 5.6 × 0.94)
= 5.1 kW OK: fulfills the load 4.5 kW
Go on to the heating trial calculation since the selected units fulfill the cooling loads of Room 1, 2.
Note: If CTx = CTi, please refer to the <Heating> section to calculate the Maximum Indoor Unit Capacity of Each Room.
