When the compressor is running, please check white floating ball inside as oil
level indicator and it’s recommended to maintain oil level between High and Middle; if the
level is higher than High, oil must be drained to keep the level below the bottom of gears; if
the level is between Middle and Low, oil return must be done or oil charge must be
replenished; else if the level is lower than Low, the compressor must be stopped
emergently to prevent dry wear of oil pump and bearing failure.
