1SAFETY PRECAUTION
1-1. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R410A
Use new refrigerant pipes.
Avoid using thin 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.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Store the piping to be used indoors during
installation and both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
If large amount of mineral oil enters, that can cause deterioration of refrigerant oil etc.
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.
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.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
2
[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.)

1-2. PRECAUTIONS FOR SALT PROOF TYPE "-BS" MODEL
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 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.

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.

4-2-1. PUMY-P100VHMB PUMY-P100VHMB-BS
*Before calculating the sum of total capacity of indoor units, please convert the value into the kW model capacity
(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:
Rated cooling capacity
Rated heating capacity
• 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.
Individual capacity under stated conditions = total capacity under the stated conditions o
4-3-2. 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
4-3-3. 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.

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: 240 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.
NOTES:
• 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) and LED1, LED2 (LED indication) found on
the multi-controller of the outdoor unit.
LED indication : Set all contacts of SW1 to OFF.
• During normal operation
The LED indicates the drive state of the controller in the outdoor unit.
Bit
Indication
• 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.
