The compressors were delivered at the time specified by the supplier, they are functional. Unfortunately, they only have a two-core supply cable, and since this device has a metal body, they are in Class I electrical equipment and a protective conductor must be connected to the compressor frame. Thus, it is necessary to disassemble the compressor, replace the supply cable, cut a thread in the body and solder the wires to the coils. Without this modification, it is not possible (at least in the Czech Republic) to operate this device.
Product arrived in good state, matches description, was sent quickly and arrived within a week. Great price also.
