C Doing so will cause malfunction of the unit For the above vacuum pump 1 2 and vacuum pump adapter 3 those for R22 type units can be used for R410A type However they must be used exclusively for R410A and never alternately with R22 and 407 To prevent other refrigerants R22 R407C from being mistakenly charged to this unit sizes of the service ports and flare nuts of the narrow tube service valve and wide tube service valve have been altered 12 4 Tubing Installation Procedures When the tubes are connected always apply HAB oil on the flare portions to improve the sealing of tubing The following is the HAB oil generally used Esso ZERICE 532 For details on tubing installation procedures refer to the installation manuals attached to the indoor unit and outdoor unit 55 12 5 In Case of Compressor Malfunction CAUTION e Should the compressor malfunction be sure to make the switch to a replacement compressor as quickly as possible e Use only the tools indicated exclusively for R410A See 12 3 Tools Specifically for RA10A 12 5 1 Procedure for Replacing Compressor 1 Recovering refrigerant e Anyremaining refrigerant inside the unit should not be released to the atmosphere but recovered using the refrigerant recovery unit for R410A Do not reuse the recovered refrigerant since it will contain impurities 2 Replacing Compressor Soon after removing seals of both disch
