2 SAFETY PRECAUTION

Cautions for units utilizing refrigerant R410A

2-1. CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

Make sure that the inside and outside of refrige­rant piping is clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shaving particles, etc.
In addition, use pipes with specified thickness.

Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)

Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.

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 refrige­rant 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.

Keep the tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com­pressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigera­nt will change and the efficiency will be lowered.

Tools for R410A

Contamination inside refrigerant piping can cause deterio­ration of refrigerant oil etc.

If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com­pressor.

If large amount of mineral oil enters, that can cause deterio­ration of refrigerant oil etc.

Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

No. Tool name Specifications
1 Gauge manifold ·Only for R410A

·Use the existing fitting

specifications

. (UNF1/2)

·Use high-tension side pressure of 5.3MPa·G or over.
2 Charge hose ·Only for R410A

·Use pressure performance of 5.09MPa·G or over.
3 Electronic scale
4 Gas leak detector ·Use the detector for R134a, R407C or R410A.
5 Adaptor for reverse flow check ·Attach on vacuum pump.
6 Refrigerant charge base
7 Refrigerant cylinder ·Only for R410A ·Top of cylinder (Pink)

·Cylinder with syphon
8 Refrigerant recovery equipment

[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.)

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 uint 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 time 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 0.7mm 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 refriger­ ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been speci­ fied separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also
have 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.

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 rati ngs
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 5-2.STANDARD CAPACITY DIAGRAM.

(1) Capacity of indoor unit

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 5-1-1. (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 o 2 + 5.6 o 2=16.8kW
Therefore, the capacity of PKFY-P25VAM-E and
PLFY-P50VLMD-E will be calculated as follows by
using the formula in 5-1-2. (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 o 2 + 6.3 o 2=19.0
Therefore, the capacity of PKFY-P25VAM-E and PLFY­P50VLMD-E will be calculated as follows by using the
formula in 5-1-2. (1):

Model 25=16.33 o = 2.75kW

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 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 (5m) as “1.0”.

• Standard conditions:

• Use the rated capacity and rated input given in “5-2.”.

• 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.

5-3-2. 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.

(2) Method for Obtaining the Equivalent Piping Length

Equivalent length for type P100·125·140 = (length of piping to farthest indoor unit) + (0.3 o number of bends in the piping) (m)

Length of piping to farthest indoor unit: type P100~P140.....80m

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.

During normal operation
The LED indicates the drive state of the controller in the outdoor unit.

When fault requiring inspection has occurred,
the LED alternately indicates the inspection code and the location of the unit in which the fault has occurred.

NOTES:

1. Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.
Self-diagnosis function
The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch
(SW1), LED1 and LED2 (LED indication) found on the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.

Cautions when Servicing

!

WARNING: When the main supply is turned off, the voltage [540 V] in the main capacitor will drop to 20 V in approx. 5 minutes (input voltage: 380 V).
When servicing, make sure that LED1 and LED2 on the outdoor circuit board goes out, and then wait for at least 5 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.
