    Liebert BU067A: compressor unloader valve???

    I'm having problems with a Liebert BU067A-AAE13411 system (5 ton scroll). Does it have a compressor unloader valve? If so, is it located right before the hot gas bypass valve? And how does it work or what is the sequence of operation?

    This unit will only have a solenoid valve before the HGBP valve which is energized whenever the unit is in cooling. During dehumidification, this valve is closed.
