1 SAFETY PRECAUTION

1-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuit must be disconnected.

1-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

Use new refrigerant pipes.

Make sure that the inside and outside of refrigerant piping is clean and it has no contaminants such as sulfur, oxides, dirt, shaving particles, etc, which are hazard to refrigerant cycle. 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.

The refrigerant oil applied to flare and flange connections must be ester oil, ether oil or alkylbenzene oil in a small amount.

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

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.

Tools for R410A Gauge manifold Charge hose

Gas leak detector

Torque wrench

Flare tool Size adjustment gauge Vacuum pump adaptor

Electronic refrigerant charging scale

Handle tools with care.

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

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 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.

[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.)

1-3. 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 times higher than that of R22, their sizes of flared sections and flare nuts are different.

1 Thickness 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 0.7 mm [7/256 inch] or below.)

2 Dimensions 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 has been specified separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also has 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.

4-2-1. Correcting Changes in Air Conditions

(1)The performance curve charts (Figure 1-1, 1-2, 2-1, 2-2) 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:

Rated cooling capacity

Rated heating capacity

• Use the rated capacity and rated power values given in the characteristics table for each indoor unit.

• The capacity is the single value on the side of the outdoor unit; The capacity on the sides of each indoor unit must be added to obtain the total capacity. (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.

8-2. CHECK POINTS FOR TEST RUN

8-2-1. Before test run

Turn on the main power switch more than 12 hours before starting operation. Starting operation just after turning on the

power switch can severely damage the internal parts. Keep the main power switch turned on during the operation season.

After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, loose-

ness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply. Use a 500-volt M-ohm tester to check that the resistance between the power supply terminals and ground is at least 1 M". Do not carry out this test on the control wiring (low voltage circuit) terminals.

Warning: Do not use the air conditioner if the insulation resistance is less than 1 MΩ.

Insulation resistance

After installation or after the power source to the unit has been cut for an extended period, the insulation resistance will drop below 1 M" due to refrigerant accumulating in the compressor. This is not a malfunction. Perform the following procedures.

1. Remove the wires from the compressor and measure the insulation resistance of the compressor.

2. If the insulation resistance is below 1 M", the compressor is faulty or the resistance dropped due to the accumulation of refrigerant in the compressor.

3. After connecting the wires to the compressor, the compressor will start to warm up after power is supplied. After supplying power for the times indicated below, measure the insulation resistance again.

• The insulation resistance drops due to accumulation of refrigerant in the compressor. The resistance will rise above 1M" after the compressor is warmed up for 4 hours. (The time necessary to warm up the compressor varies according to atmospheric conditions and refrigerant accumulation.)

• To operate the compressor with refrigerant accumulated in the compressor, the compressor must be warmed up at least 12 hours to prevent breakdown.

4. If the insulation resistance rises above 1 M", the compressor is not faulty.

Caution:

• The compressor will not operate unless the power supply phase connection is correct.

• Turn on the power at least 12 hours before starting operation.

Staring operation immediately after turning on the main power switch can result in severe damage to internal parts.

Keep the power switch turned on during the operational season.

The followings must be checked as well.

• The outdoor unit is not faulty. LED on the control board of the outdoor unit flashes when the outdoor unit is faulty.

• Both the gas and liquid stop valves are completely open.

8-2-2. Test run (1) Using remote controller

Refer to the indoor unit installation manual.

• Be sure to perform the test run individually for each indoor unit. Make sure each indoor unit operates properly following the installation manual attached to the unit. If you perform the test run for indoor units connected all at once, faulty connections of the refrigerant pipes and cables cannot be detected.

* The compressor operation is not available for 3 minutes at least after the power is supplied.

• The compressor can emit noise just after turn on the power supply or in case of low outside air temperature.

About the restart protective mechanism

Once the compressor stops, the restart preventive device operates so the compressor will not operate for 3 minutes to protect the air conditioner.

Page 41

(2) Using SW4 in outdoor unit

In case of the test run from outdoor unit, all indoor units operate. Therefore, you cannot detect any erroneous connection of refrigerant pipes and the connecting wires. If it aims at detection of any erroneous connection, be sure to carry out the test run from remote controller with reference to "(1) Using remote controller."

SW4-1 SW4-2 SW4-1 SW4-2

+ After performing the test run, set SW4-1 to OFF.

• A few seconds after the compressor starts, a clanging noise may be heard from the inside of the outdoor unit. The noise is coming from the check valve due to the small difference in pressure in the pipes. The unit is not faulty.

The test run operation mode cannot be changed by DIP switch SW4-2 during the test run. To change the test run operation mode during the test run, stop the test run by DIP switch SW4-1. After changing the test run operation mode, resume the test run by switch SW4-1.

ON OFF ON ON

Cooling operation

Heating operation

When a test run is started by “Using SW4 in outdoor unit”, even if it carries out stop instructions by remote controller, outdoor unit does not stop. A test run is not ended. In this case, please set SW4 in outdoor unit to off.

• After power is supplied or after an operation stops for a while, a small clicking noise may be heard from the inside of the branch box. The electronic expansion valve is opening and closing. The unit is not faulty.

NOTE: Be sure to wait at least 3 minutes after turning on the power supply before setting SW4-1 and SW4-2. If the DIP switches are set before 3 minutes has elapsed, the test run may not start.

8-2-3. Test run by outdoor unit SW4

The setting of test run (ON/OFF) and its operation mode (cooling/heating) can be set by SW4 on the controller board of outdoor unit.

1 Set operation mode (cooling or heating) by SW4-2. 2 Start test run by setting SW4-1 to ON ( 3 Finish test run by setting SW4-1 to OFF ( ).

• Operation mode cannot be changed by SW4-2 during test run. Stop test run to change operation mode by SW4-1, and restart test run by SW4-1 after the mode is changed.

• Test run automatically stops 2 hours later by 2-hour OFF timer function.

• Test run can be performed by the remote controller.

• The remote controller display of test run by outdoor unit is the same as that of test run by remote controller.

• If test run is set with the outdoor unit, the test run is performed for all indoor units.

• The remote controller operation becomes unavailable once the test run is set with the outdoor unit.

(3) How to attach and detach the coil of linear expansion valve

<Composition> Linear expansion valve is separable into the main body and the coil as shown in the diagram below.

Coil

Lead wire

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and detach the coil by pulling it upward. Be sure to detach the coil holding main body firmly. Otherwise pipes can bend due to pressure.

Stopper

Main body

Hold the lower part of the main body (shown as A) firmly so that the main body does not move and attach the coil by inserting it downward into the main body. Then securely attach the coil stopper to pipe B. (At this time, be careful that stress is not added to lead wire and main body is not wound by lead wire.) If the stopper is not firmly attached to pipe B, coil may be detached from the main body and that can cause defective operation of linear expansion valve. To prevent piping stress, be sure to attach the coil holding the main body of linear expansion valve firmly. Otherwise pipe may break.

Be sure to attach the stopper to pipe B.

Troubleshooting

Problem

Locked expansion valve

Short circuit or broken circuit in expansion valve motor coil

Valve does not close completely.

Incorrect connection or connection failure

Check point

If the linear expansion valve becomes locked and the motor is still operating, the motor will emit a clicking noise and will not function. This clicking noise indicates an abnormality.

Use an all-purpose electrical meter to measure the resistance between the different coils (red-white, red-orange, brown-yellow, brown-blue). Normal resistance is within a range of 46Ω ± 4%.

In order to check the linear expansion valve, operate 1 indoor unit in the fan mode and another in the cooling mode. Then, use the outdoor multi controller board to operate the monitor and check the pipe temperature of the indoor unit. The linear expansion valve should be fully closed when the fan is operating. The temperature measured by the temperature sensor will drop if there is any leakage. If the measured temperature is significantly lower than that on the remote controller, this indicates that the valve is not closed. It is not necessary to replace the linear expansion valve if the leak of refrigerant is small and does not cause a malfunction.

 Check improperly connected connector terminals and the wire colors.  Remove the connector on the controller board side and check electrical

conductance.

Corrective measure

Replace the linear expansion valve.

Replace the linear expansion valve if there is a major leak of refrigerant.

9 PRECAUTIONS AGAINST REFRIGERANT LEAKAGE

The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following standards may be applicable if local regulations are not available.

9-1. 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.

* 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[0.019lbs/ft³]

(KHK installation guidelines S0010)

Outdoor unit

Direction of refrigerant flow

Indoor unit

All refrigerant of this system will leak out to this

room if there is leakage at this indoor unit.

9-2. 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.

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

(2) Calculate room volumes (K[ft³]) 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

Indoor unit

Page 80

(b) There are partitions, but there are openings that allow the effective mixing of air.

Outdoor unit

Indoor unit

Opening

Wall

(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.

Ventilation apparatus

The smallest room

The second smallest room

(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)

Outdoor unit

Indoor unit

(3) Use the results of calculations (1) and (2) to calculate the refrigerant concentration:

Total refrigerant in the refrigerating unit (O[lbs]) [ maximum concentration The smallest room in which an indoor (O/K[lbs/ft³]) unit has been installed (K[ft³]) Maximum concentration of

R410A: 0.3O/K[0.019 lbs/ft³]

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.
