Cautions for units utilizing refrigerant R410A
CAUTIONS RELATED TO NEW REFRIGERANT
Use new refrigerant pipes.
Store the piping indoors, and 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) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is syphon type.
·
Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

Cautions for refrigerant piping work
New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same
as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working
pressure of R410A is 1.6 times higher than that of R22, their sizes of flared sections and flare nuts are different.
1Thickness of pipes
Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness
shown below. (Never use pipes of 0.7 mm or below.)
2Dimensions of flare cutting and flare nut
The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that,
R410A is a refrigerant, which has higher risk of leakage because its working pressure is higher than that of other refrig-
erants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A has been
specified separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A
also has partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe
flaring dimensions for R410A below. For 1/2 and 5/8 inch, the dimension B changes.
Use torque wrench corresponding to each dimension.

4-1. COOLING AND HEATING CAPACITY AND CHARACTERISTICS
4-1-1. Method for obtaining system cooling and heating capacity:
To obtain the system cooling and heating capacity and the electrical characteristics of the outdoor unit, first add up the ratings
of all the indoor units connected to the outdoor unit (see table below), and then use this total to find the standard capacity with
the help of the tables on 4-2. STANDARD CAPACITY DIAGRAM.

Model Capacity 6 8 12 15 18 24 27 30 36 48 54 72
4-1-2. Method for obtaining the heating and cooling capacity of an indoor unit:
(1) The capacity of each indoor unit (Btu/h) = the capacity A(or B) o
(2) Sample calculation (using the system described above in 4-1-1. (2) ):
model capacity
total model capacity of all indoor units
During cooling: During heating:
• The total model capacity of the indoor unit is:
8000 o2 + 18000 o3 = 70000Btu/h
Therefore, the capacity of PKFY-P08NAMU-E and
PLFY-P18NBMU-E will be calculated as follows by
using the formula in 4-1-2. (1):
Model 08= 62,000 o= 7,090 Btu/h
Model 18= 62,000 o= 15,940 Btu/h
• The total model capacity of indoor unit is:
9000 o2 + 20000 o3 = 78000 Btu/h
Therefore, the capacity of PKFY-P08NAMU-E and
PLFY-P18NBMU-E will be calculated as follows by
using the formula in 4-1-2. (1):
Model 08= 68,000 o= 7,850 Btu/h
Model 18= 68,000 o= 17,440 Btu/h
8000
70000
(2) Sample calculation

the outdoor unit)
• Outdoor unit PUMY-P60NKMU
• Indoor unit PKFY-P08NAMU-E o2 , PLFY-P18NBMU-E o3
2According to the conditions in 1, the total capacity of the indoor unit will be: 8 o2 + 18 o3 = 70

4-4. CORRECTING COOLING AND HEATING CAPACITY
4-4-1. Correcting changes in air conditions
(1) The performance curve charts (Figure 1, 2) show the ratio by the temperature condition change when the rated capacity (total
capacity) and the rated input are presumed 1, under standard length (7.6 m [25 ft]) and standard temperature condition.
• Standard conditions:
• Use the rated capacity and rated input given in “4-2.”.
• The input is the single value on the side of the outdoor unit; the input on the sides of each indoor unit must be added to
obtain the total input.
(2) The capacity of each indoor unit may be obtained by multiplying the total capacity obtained in (1) by the ratio between the
individual capacity at the rated time and the total capacity at the rated time.

4-4-2. Correcting capacity for changes in the length of refrigerant piping
(1) During cooling, obtain the ratio (and the equivalent piping length) of the outdoor units rated capacity and the total in-use
indoor capacity, and find the capacity ratio corresponding to the standard piping length from Figure 3. Then multiply by
the cooling capacity from Figure 1 to obtain the actual capacity.
(2) During heating, find the equivalent piping length, and find the capacity ratio corresponding to standard piping length from
Figure 3. Then multiply by the heating capacity from Figure 2 to obtain the actual capacity.

SV1 are turned during cooling
operation.
Cautions when servicing
!
• WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2
minutes (input voltage: 230 V). When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then
wait for at least 1 minute.
• Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual.
Do not replace the outdoor board without checking.
