INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT

This room air conditioner adopts an HFC refrigerant (R410A) which never destroys the ozone layer.

Pay particular attention to the following points, though the basic installation procedure is same as that for R22 conditioners. 1 As R410A has working pressure approximate 1.6 times as high as that of R22, some special tools and piping parts/

materials are required. Refer to the table below.

2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and installation, since it is more susceptible to contaminations than R22.

3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R410A. (Refer to 2. Refrigerant piping.)

4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change.

1. Tools dedicated for the air conditioner with R410A refrigerant

The following tools are required for R410A refrigerant. Some R22 tools can be substituted for R410A tools.

The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being charged into the unit. Cap size has been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads.

3. Refrigerant oil

Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces.

4.Air purge

Do not discharge the refrigerant into the atmosphere.

Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit.

Use the vacuum pump for air purging for the purpose of environmental protection.

5.Additional charge

For additional charging, charge the refrigerant from liquid phase of the gas cylinder.

If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

Indoor air wet/dry-bulb temperature difference on the side of the chart on page shows the difference between the indoor intake air wet/dry-bulb temperature and the indoor outlet air wet/dry-bulb temperature for your reference at service.

How to measure the indoor air wet-bulb/dry-bulb temperature difference

1.Attach at least 2 sets of wet-and-dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of wet-and-dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high.

2.Attach at least 2 sets of wet-and-dry-bulb thermometers to the outdoor air inlet. Cover the thermometers to prevent direct rays of the sun.

3.Check that the air filter is cleaned.

4.Open windows and doors of the room.

5.Press the EMERGENCY OPERATION switch once to start the COOL(HEAT) MODE.

6.When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.

7.10 minutes later, measure temperature again and check that the temperature does not change.

<How to operate fixed-frequency operation (Test run operation)>

1.Press the EMERGENCY OPERATION switch to COOL or HEAT mode.

2.Test run operation starts and continue to operate for 30 minutes.

3.Compressor starts at rated frequency in COOL mode or 58Hz in HEAT mode.

4.Indoor fan operates at High speed.

5.After 30 minutes, test run operation finishes and EMERGENCY OPERATION starts.

6.To cancel test run operation (EMERGENCY OPERATION), press the EMERGENCY OPERATION switch or any button on remote controller.

NOTE : The unit of pressure has been changed to MPa on the international system of units (SI unit system). The conversion factor is: 1(MPa [Gauge]) =10.2(kgf/f [Gauge])

The standard data contained in these specifications apply only to the operation of the air conditioner under normal condition. Operating conditions vary according to the areas where these units are installed. The following information has been provided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

Indoor air wet/dry-bulb temperature difference on the side of the chart on page shows the difference between the

indoor intake air wet/dry-bulb temperature and the indoor outlet air wet/dry-bulb temperature for your reference at service.

How to measure the indoor air wet-bulb/dry-bulb temperature difference

1.Attach at least 2 sets of wet-and-dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of wet-and-dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high.

2.Attach at least 2 sets of wet-and-dry-bulb thermometers to the outdoor air inlet. Cover the thermometers to prevent direct rays of the sun.

3.Check that the air filter is cleaned.

4.Open windows and doors of the room.

5.Press the TEST button twice to start the COOL(HEAT) MODE.

6.When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.

7.10 minutes later, measure temperature again and check that the temperature does not change.

<How to operate fixed-frequency operation (Test run operation)>

1.Press the TEST button to COOL or HEAT mode.

2.Test run operation starts and continue to operate for 30 minutes.

3.Compressor starts at rated frequency in COOL mode or 58Hz in HEAT mode.

4.Indoor fan operates at High speed.

5.After 30 minutes, test run operation finishes and EMERGENCY OPERATION starts.

6.To cancel test run operation (EMERGENCY OPERATION), press the ON/OFF button on remote controller.

NOTE : The unit of pressure has been changed to MPa on the international system of units (SI unit system). The conversion factor is: 1(MPa [Gauge]) =10.2(kgf/f [Gauge])
