2 SAFETY PRECAUTION
Cautions for using with the outdoor unit which adopts R407C refrigerant.
· Do not use the existing refrigerant piping.
-The old refrigerant and refrigerant oil in the existing piping contains a large amount of chlorine which may cause the refriger-
ant oil of the new unit to deteriorate.
· Do not use copper pipes which are broken, deformed or discolour .
In addition, be sure that the inner surfaces of the pipes are clean, free of hazardous sulphur and oxides, or have no dust /
dirt, shaving particles, oils, moisture or any other contamination.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the refrigerant oil will
result.
· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use ester oil, ether oil or alkyl benzene (small amount) as the refrigerant oil to coat flares and flange connections.
-The refrigerant oil will degrade if it is mixed with a large amount of mineral oil.
Use liquid refrigerant to fill the system.
-If gas refrigerant is used to fill the system, the composition of the refrigerant in the cylinder will change and performance
may drop.
· Do not use a refrigerant other than R407C.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerant oil to deteriorate.
· Use a vacuum pump with a service port.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerant oil to deteriorate.
· Do not use the following tools that are used with conventional refrigerant.
(Gauge manifold , charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge,
refrigerant recovery equipment)
-If the conventional refrigerant and refrigerant oil are mixed in the R407C, the refrigerant may deteriorated.
-If water is mixed in the R407C, the refrigerant oil may deteriorate.
-Since R407C does not contain any chlorine, gas leak detectors for conventional refrigerant will not react to it.
· Do not use a charging cylinder.
-Using a charging cylinder may cause the refrigerant to deteriorate.
· Be especially careful when managing the tools.
-if dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
· Do not use the drier which is sold in the field.
-The drier for R407C refrigerant is pre-attached to outdoor unit refrigerant circuit.
-Some drier in the field are not in conformity with R407C refrigerant.

[3] Refrigerant recharging
(1) Refrigerant recharging process
1Direct charging from the cylinder.
·R407C cylinder are available on the market has a syphon pipe.
·Leave the syphon pipe cylinder standing and recharge it.
(By liquid refrigerant)
(2) Recharge in refrigerant leakage case
·After recovering the all refrigerant in the unit, proceed to working.
·Do not release the refrigerant in the air.
·After completing the repair service, recharge the cycle with the specified amount of
liquid refrigerant.

5-1. COOLING AND HEATING CAPACITY AND CHARACTERISTICS
5-1-1. 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 page 11 to 14.

5-1-2. 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-P25VAM-A and
PLFY-P50VLMD-A will be calculated as follows by
using the formula in 4-1-2. (1):
Model 25=14.6 o= 2.43kW
Model 50=14.6 o= 4.87kW
• The total model capacity of indoor unit is:
3.2 o2 + 6.3 o2=19.0
Therefore, the capacity of PKFY-P25VAM-A and PLFY-
P50VLMD-A will be calculated as follows by using the
formula in 4-1-2. (1):
Model 25=16.33 o= 2.75kW
Model 50=16.33 o= 5.41kW

5-3. CORRECTING COOLING AND HEATING CAPACITY
5-3-1. Correcting Changes in Air Conditions
(1)The performance curve charts (Figure 1, 2) show the rated capacity (total capacity) under the stated conditions when standard
length for piping (5m) is used. The rated power is derived from the capacity ratio and power ratio obtained for the indoor and
outdoor intake temperatures at time 1.
• Standard conditions:
• Use the rated capacity and rated power values given in the characteristics table for each indoor unit.
• The capacity is the single value on the side of the outdoor unit; the capacity on the sides of each indoor unit must be
added to obtain the total capacity.
(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

5-3-2. Correcting Capacity for Changes in the Length of Refrigerant Piping
(1) During cooling, to obtain the ratio (and the equivalent piping length) of the outdoor units rated capacity and the total
in-use indoor capacity, first find the capacity ratio corresponding to the standard piping length (5m) from Figures 3
at first, and then multiply by the cooling capacity from Figure 1 to obtain the actual capacity.
(2) During heating, to find the equivalent piping length, first find the capacity ratio corresponding to standard piping length (5m)
from Figure 4, and then multiply by the heating capacity from Figure 2 to obtain the actual capacity.

5-3-3. Correction of Heating Capacity for Frost and Defrosting
If heating capacity has been reduced due to frost formation or defrosting, multiply the capacity by the appropriate correction
factor from the following table to obtain the actual heating capacity.
