INFORMATION FOR THE AIR CONDITIONER WITH R-407C REFRIGERANT
This room air conditioner adopts HFC refrigerant (R407C) which will never destroy the ozone layer. Pay attention to following points.
1Take sufficient care not to allow water and other contaminations to enter the R407C refrigerant during storage and installation, since it is more susceptible to contaminations than HCFC (R22) refrigerant.
2 Clean refrigerant pipings should be used.
3Composition change may occur in R407C since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change.
4Be especially careful when managing the tools.
If dust, dirt, or water mixes in the refrigerant cycle, it may cause decrease of performance.

1.Tools dedicated for the air conditioner with R407C refrigerant
The following tools are required for R407C refrigerant. Some R22 tools can be substituted for R407C tools. Do not use tools that are used with R22 refrigerant in order to avoid mixing oils.

2.Refrigerant piping
Do not use copper pipes which are broken, deformed or discoloured.
In addition, be sure that the inner surfaces of the pipes are clean, free of hazardous sulfur and oxides, or have no dust/ dirt, shaving particles, oil, moisture or any other contamination.
•If there is a large amount of residual oil inside the piping and joints, deterioration of the refrigerant oil will result.
3.Refrigerant oil
Apply the specific refrigeration oil (accessories) to the flare and the union seat surfaces.
4.Air purge
Use the vacuum pump for air purge to protect environments, and to avoid changing the composition of refrigerant.
5.Additional charge
For additional charging, charge the refrigerant with liquid phase slowly using a gas cylinder. If the refrigerant is charged with gas phase, the composition of refrigerant will change. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible.
If liquid refrigerant is rapidly charged at once, the compressor may be locked.
NOTE: 1. The R407C is mixed refrigerant which consist of three different kinds of evaporative temperature. As a result, the R407C occurs the change of composition.
2.Additional refrigerant charge has been changed by change of refrigerant.(R22 R407C) R22 : <MU-type> 15g/m R407C : <MU-C18/C24TV> 20g/m

The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions. Since 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.
(1)GUARANTEED VOLTAGE
Rated voltage : 207 ~ 253V,50Hz
(2)AIR FLOW
Air flow should be set at MAX.

Indoor air wet/dry-bulb temperature difference on the left side of the chart on next 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 intake 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 dry-bulb thermometers to the outdoor air intake. Cover the thermometers to prevent direct rays of the sun.
3.Check that the air filter is cleaned.
4.Open windows and doors of room.
5.Press the EMERGENCY OPERATION switch once to start the EMERGENCY COOL 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.
