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 enter into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.

Do not use a charging cylinder.

New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410Ais 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 of its working pressure 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”, the dimension B changes.

Use torque wrench corresponding to each dimension.

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 define 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.

Individual capacity under stated conditions = total capacity under the stated conditions o

Corrected pipe length

(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 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

from Figure 3, and then multiply by the heating capacity from Figure 2 to obtain the actual capacity.

(1) Capacity CORRECTION CURVE

(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.

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, 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.

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) 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.

(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.

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 guide-

✻ 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)

Maximum concentration of R410A: 0.3O/K

(KHK installation guidelines S0010)

(2) Calculate room volumes (K) and find the room

with the smallest volume

The part with represents the room with the smallest volume.

Follow (1) to (3) to confirm the R410A concentration and take appropriate treatment, if necessary.

(1) Calculate total refrigerant amount by each refrig-

erant system. Total refrigerant amount is precharged refrigerant amount at ex-factory plus additional charged amount at field installation.

Note: When single refrigeration system is consists of several independent refrigeration circuit, figure out the total refrigerant amount by each independent refrigerant circuit.
