Cautions for units utilizing refrigerant R410A
1-1. 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 a syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)
Although "-BS" model has been designed to be resistant to salt damage, observe the following precautions to maintain the
performance of the unit.
1. Avoid installing the unit in a location where it will be exposed directly to seawater or sea breeze.
2. If the cover panel may become covered with salt, be sure to install the unit in a location where the salt will be washed away by
rainwater. (If a sunshade is installed, rainwater may not clean the panel.)
3. To ensure that water does not collect in the base of the outdoor unit, make sure that the base is level, not at angle. Water
collecting in the base of the outdoor unit could cause rust.
4. If the unit is installed in a coastal area, clean the unit with water regularly to remove any salt build-up.
5. If the unit is damaged during installation or maintenance, be sure to repair it.
6. Be sure to check the condition of the unit regularly.
7. Be sure to install the unit in a location with good drainage.

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 strength, 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 strength as shown below. Set copper pipe correctly referring to copper pipe
flaring dimensions for R410A below. For 1/2 and 5/8 inch pipes, 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 "4-3. STANDARD CAPACITY DIAGRAM".
(1) Capacity of indoor unit
4-1-2. Method for obtaining the heating and cooling capacity of an indoor unit:
(1) The capacity of each indoor unit (kW) = 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:
2.8 o2 + 5.6 o2=16.8kW
Therefore,thecapacityofPKFY-P25VBM-Eand
PLFY-P50VLMD-Ewillbecalculatedasfollows
by using the formula in 4-1-2. (1):
Model 25=14.6 o= 2.43 kW
Model 50=14.6 o= 4.87 kW
•Thetotalmodelcapacityofindoorunitis:
3.2 o2 + 6.3 o2=19.0
Therefore,thecapacityofPKFY-P25VBM-Eand
PLFY-P50VLMD-Ewillbecalculatedasfollowsby
using the formula in 4-1-2. (1):
Model 25=16.33 o= 2.75 kW
Model 50=16.33 o= 5.41 kW

the outdoor unit)

 •IndoorunitPKFY-P25VBM-Eo2,PLFY-P50VLMD-Eo2
2 According to the conditions in 1, the total capacity of the indoor unit will be: 2.8 o2 + 5.6 o2 = 16.8
3 The following figures are obtained from the 16.8 total capacity of indoor units, referring the standard capacity diagram in

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 change ratio of capacity and input (power consumption) according to the
indoor and outdoor temperature condition when defining the rated capacity (total capacity) and rated input under the standard
condition in standard piping length (5 m) as “1.0”.
•Standardconditions:
•Usetheratedcapacityandratedinputgivenin“4-3.STANDARDCAPACITYDIAGRAM”.
•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. individual capacity at the rated time
Individual capacity under stated conditions = total capacity under the stated conditions ototal capacity at the rated time
