SAFETY PRECAUTION
CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Use new refrigerant pipes.
Do not use refrigerant other than R410A.
Avoid using thin pipes.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
Make sure that the inside and outside of refrigerant piping are clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shredded particles, etc.
In addition, use pipes with specified thickness.
Use a vacuum pump with a reverse flow check
valve.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
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.
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.)
Gauge manifold
Charge hose
Gas leak detector
Torque wrench
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Tools for R410A
Flare tool
Size adjustment gauge
Vacuum pump adaptor
Electronic refrigerant
charging scale
Keep the tools with care.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
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.
Do not use a charging cylinder.
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.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

[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 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 refrigerants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A have been specified 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 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 5-2.STANDARD CAPACITY DIAGRAM.

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):
• 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):

5-3. CORRECTING COOLING AND HEATING CAPACITY
5-3-1. Correcting Capacity for 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:
Indoor D.B. 27°C / W.B. 19°C
Rated cooling capacity
Outdoor D.B. 35°C
Indoor D.B. 20°C
Rated heating capacity
Outdoor D.B. 7°C / W.B. 6°C
• Use the rated capacity and rated input given in “5-2.”.
• The input is the single value of the outdoor unit; the input 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 under stated conditions = total capacity under the stated conditions o
individual capacity at the rated time
total 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 from Figure 3,
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
from Figure 3, and 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.

2 The state that data cannot to be output to
the transmission line by noise for 8 to 10
minutes consecutively.
Note) Address/Attribute displayed on the

Causes
1) The transmission processor cannot
be transmitted since a short cycle
voltage of the noise etc. mixes on
the transmission line consecutively.
Check points
1 Check whether the transmission line
of the indoor unit, fresh master,
lossnay and remote controller is
connected to the outdoor unit terminal
board (TB7) for centralized controller
or not.
2) The transmission volume increases
and cannot be transmitted since the
wiring method is mistaken and the
routing technique to the terminal
board (TB3) for the transmission
line of the outdoor unit and the
terminal board (TB7) for centralized
control cannot be transmitted.
2 Check whether the transmission line
with the other refrigerant system of the
indoor unit and lossnay is connected to
the outdoor unit terminal board (TB3)
for transmission or not.
3) The share becomes high since the
data exists together to other
transmitted data by a defective
repeater (function which connects
and intercepts the transmission of
controlling system and centralized
control system), and it causes
abnormal detection.
3 Check whether the outdoor unit
terminal board for transmission line

ELECTRICAL WIRING
This chapter provides an introduction to electrical wiring for the CITY MULTI-S series, including notes concerning power wiring,
wiring for control (transmission wires and remote controller wires), and the frequency converter.
10-1. OVERVIEW OF POWER WIRING
(1) Use a separate power supply for the outdoor unit and indoor unit.
(2) Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water,etc.) when proceeding with the wiring and connections.
(3) The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops.
Make sure the power-supply voltage does not drop more than 10 %.
(4) Specific wiring requirements should adhere to the wiring regulations of the region.
(5) Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57).
For example, use wiring such as YZW.
(6) Install an earth longer than other cables.
Warning:
· Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly,
it may cause heating or fire.
· Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct
current.
Caution:
· Some installation site may require attachment of an earth leakage breaker. If no earth leakage breaker is installed, it may cause an electric
shock.
· Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too large capacity may cause a
malfunction of unit or fire.

In order to identify the destinations of signals to the outdoor units, indoor units, and remote controller of the MULTI-S
series, each microprocessor must be assigned an identification number (address). The addresses of outdoor units, indoor
units, and remote controller must be set using their settings switches. Please consult the installation manual that comes with
each unit for detailed information on setting procedures.

10-6. METHOD FOR OBTAINING ELECTRICAL CHARACTERISTICS WHEN A CAPACITY
AGREEMENT IS TO BE SIGNED WITH AN ELECTRIC POWER COMPANY
The electrical characteristics of connected indoor unit system for air conditioning systems, including the MULTI-S
series, will depend on the arrangement of the indoor and outdoor units.
First read the data on the selected indoor and outdoor units and then use the following formulas to calculate the electrical
characteristics before applying for a capacity agreement with the local electric power company.

11-2. PRECAUTIONS AGAINST REFRIGERANT LEAKAGE
11-2-1. Introduction
R410A refrigerant of this air conditioner is non-toxic and
non-flammable but leaking of large amount from an indoor
unit into the room where the unit is installed may be deleterious.
To prevent possible injury, the rooms should be large
enough to keep the R410A concentration specified by KHK :
(a high pressure gas safety association) installation guidelines S0010 as follows.
(2) Calculate room volumes (K) and find the room
with the smallest volume
The part with
represents the room with the smallest
volume.
(a) Situation in which there are no partitions
Outdoor unit
✻ Maximum concentration
Maximum refrigerant concentration of R410A of a room
is 0.30 kg/K accordance with the installation guidelines.
To facilitate calculation, the maximum concentration is
expressed in units of O/K ( kg of R410A per K)
Indoor unit
Maximum concentration of R410A: 0.3O/K
(KHK installation guidelines S0010)
(b) There are partitions, but there are openings that allow
the effective mixing of air.
Outdoor unit

All refrigerant of this system will leak out to this
room if there is leakage at this indoor unit.
11-2-2. Confirming procedure of R410A concentration
Follow (1) to (3) to confirm the R410A concentration and
take appropriate treatment, if necessary.
(1) Calculate total refrigerant amount by each refrigerant system.
Total refrigerant amount is precharged refrigerant
amount at ex-factory plus additional charged
amount at field installation.
(Situation in which there
are no door openings or
in which there are openings above and blow
doors that occupy at
least 0.15% of the floor
area)
(c) If the smallest room has mechanical ventilation apparatus that is linked to a household gas detection and
alarm device, the calculations should be performed for
the second smallest room.
Outdoor unit
Ventilation apparatus
Indoor unit
Note:
When single refrigeration system is consists of several
independent refrigeration circuit, figure out the total refrigerant amount by each independent refrigerant circuit.
The smallest
room
The second
smallest room
(3) Use the results of calculations (1)and (2) to calculate the refrigerant concentration:
Total refrigerant in the refrigerating unit (O)
[ maximum concentration(O/K)
The smallest room in which an indoor
unit has been installed (K)
Maximum concentration of R410A:0.3O/K
If the calculation results do not exceed the maximum concentration, perform the same calculations for the larger second
and third room, etc., until it has been determined that nowhere
will the maximum concentration be exceeded.
