    Features and Structure] (1) Energy conservation Since the motor unit uses the highly efficient IPM motor drive system that DAIKIN originally developed, the Super Unit provides extremely high energy efficiency. The Super Unit uses the autonomously-switching dual pump system that enables autonomous control of combination mode/single mode switching according to load pressure by using the dual fixed-capacity pumps (small-capacity and large-capacity pumps) and the switching valve.

    This hydraulic unit incorporates a check valve. If an additional inline check valve is mounted to the discharge port, resonance occurs, which may have bad influence on the master machine. Therefore, do not use an inline check valve. DAIKIN INDUSTRIES, LTD.

  • Page 13: Precautions For Operation, Transportation And Installation]

    Avoid transporting the hydraulic unit with hydraulic oil contained in the tank. (This may cause oil leak, or malfunction due to air intrusion.) During transportation, hold the hydraulic unit securely so that it will not be moved by vibration or external force. DAIKIN INDUSTRIES, LTD.

  • Page 14: Precautions For Installation

    If the hydraulic unit is continuously used at a high temperature, the hydraulic equipment (pump, valves, etc.) will have defects or shortened service life, as well as the electric components described above. Using the hydraulic unit at a high temperature accelerates deterioration of the hydraulic oil, resulting in shortened service life. DAIKIN INDUSTRIES, LTD.
