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.

. (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.

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

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.

5-3-1. 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.

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.

Check ground wire, transmission cable, remote controller cable, and power supply cable for secure connection. Make sure that all switch settings of address or adjustments for special specification systems are correctly settled.

(2) Safety check :

With the insulation tester of 500V, inspect the insulation resistance. Do not touch the transmission cable and remote controller cable with the tester. The resistance should be over 1.0 M". Do not proceed inspection if the resistance is under 1.0 M". Inspect between the outdoor unit power supply terminal block and ground first, metallic parts like refrigerant pipes or the electrical box next, then inspect all electrical wiring of outdoor unit, indoor unit, and all linked equipment .

(3) Before operation :

a) Turn the power supply switch of the outdoor unit to on for compressor protection. For a test run, wait at least 12 hours

from this point.

b) Register control systems into remote controller(s). Never touch the on/ off switch of the remote controller(s). Refer

to “ 9-1-2. Special Function Operation and Settings (for M-NET Remote Controller)” as for settings. In MA remote controller(s), this registration is unnecessary.

(4) More than 12 hours later from power supply to the outdoor unit, turn all power switch to on for test run. Perform test run

according to the “Operation procedure” table of the bottom of this page. While test running, make test run reports .

(5) When you deliver the unit after test run, instruct the end user for proper usage of the system using owners’ manual and

the test run report you made to certificate normal operation. If abnormalities are detected during test run, refer to “ 9-1-3 Countermeasures for Error During Test Run”. As for DIP switch setting of outdoor unit, refer to” 9-5. INTERNAL SWITCH FUNCTION TABLE”.

10-1. OVERVIEW OF POWER WIRING

10-2. WIRE DIAMETER AND MAIN POWER SWITCH CAPACITY

10-2-1. Wiring diagram for main power supply

10-2-2. Power supply wire diameter and capacity

This chapter provides an introduction to electrical wiring for the CITY MULTI-S series, together with notes concerning power wiring, wiring for control (transmission wires and remote controller wires), and the frequency converter.

Power supply single phase 50Hz 220-230-240V

(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 60245 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.

10-4. SYSTEM SWITCH SETTING

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.

(3) Method of obtaining system power factor

Use the following formula and the total power and current obtained in parts 1 and 2 on the above tables to calculate the system power factor.

System power factor =

(Total system power consumption)

(Total system current x voltage)

o 100%

10-6-2. Applying to an electric power company for power and total current

Calculations should be performed separately for heating and cooling employing the same methods; use the largest resulting value in your application to the electric power company.

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.

10-6-1. Obtaining the electrical characteristics of a CITY MULTI-S series system

• If the total extended piping length exceeds 50m, calculate the required additional refrigerant charge using the procedure shown on the right.

• If the calculated additional refrigerant charge is a negative amount, do not charge with any refrigerant.

<Example> Outdoor model : 125 Indoor 1 : 63 A : W9.52 10m a : W9.52 15m

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.

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

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

at ex-factory plus additional charged amount at field installation.

(2) Calculate room volumes (m

) 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

(3) Use the results of calculations (1) and (2) to cal-

culate the refrigerant concentration:

If the calculation results do not exceed the maximum concen tration, perform the same calculations for the larger second and third room, etc., until it has been determined that nowhere the maximum concentration will be exceed.

Indoor unit

All refrigerant of this system will leak out to this room if there is leakage at this indoor unit.

Maximum concentration Maximum refrigerant concentration of R410A of a room is 0.3 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)

(KHK installation guidelines S0010)

Maximum concentration of R410A: 0.3O/K
