Hello!
Has anyone had any experience of retrofitting a water chiller with Hitachi 6002SC-H screw compressor running with R22? We have a leak on the system and it seems pointless to recharge with R22R post repair. According to some websites Hitachi ship the compressors with POE so oil return can't be a problem with R22. We will change the oil during the retrofit but again not sure what grade/make is best. By the Hitachi UK say they have no experience using retrofits with this compressor so any help would be greatly appreciated!
