Page 2: Technical Changes
TECHNICAL CHANGES The following are in common details. 1. Refrigerant type has changed from R-22(HCFC) to R-407C(HFC). 2. Rated voltage has changed from 220-240V to 220-230V. 3. Compressor has changed from one for R-22 to one for R-407C. 4. Jumper wire JPE for defrosting temperature change in deicer P.C.board is cut at factory shipping. 5. - Page 3 INFORMATION FOR THE AIR CONDITIONER WITH R-407C REFRIGERANT This room air conditioner adopts HFC refrigerant (R-407C) which is never destroy the ozone layer. Pay attention following points. 1 Take sufficient care not to allow water and other contaminations to enter the R-407C refrigerant during storage and installation, since it is more susceptible to contaminations than HCFC refrigerant.
- Page 4 1.Tools dedicated for the air conditioner with R-407C refrigerant The following tools are required for R-407C refrigerant. Some R-22 tools can be substituted for R-407C tools. Do not use tools that are used with R-22 refrigerant in order to avoid mixing oils. Description R-407C tools Can R-22 tools be used?
