INFORMATION FOR THE AIR CONDITIONER WITH R407C REFRIGERANT
This room air conditioner adopts HFC refrigerant (R407C) which 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.
2Clean refrigerant piping 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.
New Specification Previous Specification
The incompatible lubricant easily separates from refrigerant
and makes the layer in the upper inside the suction muffler.
The higher position of the returning oil hole enables to return
the lubricant of the upper layer to the compressor.
Since refrigerant and lubricant are compatible each other,
lubricant returns to the compressor through the lower
position returning oil hole.

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 : <MCF-type> 15g/m ➔R407C : <MCF-C13UV> 15g/m, <MCF-C18/C24UV> 20g/m
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.
R407C tools Can R22 tools be used?
Gas leak detector
A gauge manifold with a sight glass is recommended for charging the
liquid refregerant.
Hose material have been changed to improve the pressure
resistance.
Dedicated for HFC refrigerant.

Provided to prevent the back flow of oil. This adapter enables you to use
existing vacuum pumps.

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.
