  • Page 5: General Safety Guidelines

    General safety guidelines Important: Read before proceeding. This equipment is a relatively complicated apparatus. During rigging, installation, operation, maintenance, or service, individuals may be exposed to certain components or conditions including, but not limited to: heavy objects, refrigerants, materials under pressure, rotating components, and both high and low voltage.

  • Page 6: Wiring Warning

    All wiring must be in accordance with Johnson Controls’ published specifications and must be performed only by a qualified electrician. Johnson Controls will not be responsible for damage or problems resulting from incorrect connections to the controls or application of incorrect control signals.

  • Page 126: Hyp Compressor Drive Operation

    HYP compressor drive operation The new YVAM HYP Compressor Drive is specifically designed for the application of driving a permanent magnet high-speed motor with magnetic bearings used on the YORK Model YVAM Centrifugal Air-Cooled Chiller. This type of design allows the chiller to be designed as a complete system, and take full advantage of the strengths of each major component within the system.
  • Page 127 The drive components on YVAM1150, YVAM1500, and YVAM1650 (Mod B) are cooled by an ethylene glycol solution. The ethylene glycol solution in turn rejects heat through a brazed plate heat exchanger to liquid refrigerant from the condenser. The drive can now be configured for many different input voltage levels. Lower input voltages may de-rate the input current rating of the drive, but the drive produces the same output voltage and uses the same motor.

  • Page 128: Smart Sensor System

    As with drive systems used on the YCIV and YVAA chillers, this drive has a NEMA 4 outdoor enclosure rating. The drive also contains an internal heater to ensure components are not damaged due to sub-freezing conditions. A panel heater is installed inside the drive, and it is manually adjusted to 32˚F (0˚C).

  • Page 129: Low Ambient Operation

    Figure 48: Red flip dot WARNING A tripped circuit breaker is an indication of a serious fault condition. Do not reset a tripped circuit breaker without an inspection of the drive by a certified technician. Low ambient operation When power is removed, the ambient temperature in the drive may become very low. This low temperature may inhibit the chiller from starting.
  • Page 130 frequency switching of the rectifier. The load inductor provides the inductance for boosting the bus voltage above the peak of the line voltage. The higher bus voltage is required for harmonic current correction at the input of the drive, and to provide the correct output voltage for high speed operation of the compressor motor.
  • Page 131 Harmonic filter general information The harmonic filter is no longer an option with the HYP model drive. The function of the harmonic filter is now integrated into the input of the drive. The input rectifier has fast switching transistors instead of SCRs and diodes. The drive can now control the input current waveform to a near sine wave shape by controlling how the rectifiers are turned on and off.

  • Page 148 When the vacuum indicator registers this temperature or pressure, it is a positive sign that the system is dehydrated to the recommended limit. If this level cannot be reached, it indicates that there is a leak somewhere in the system. Any leaks must be corrected before you can evacuate the system to 35°F (1.6°C) or 5,000 μm (5,000 micron).

  • Page 149: Refrigerant Charging

    Operate the vacuum pump to evacuate the system to the best attainable vacuum. The vacuum must be less than 500 μm (500 micron), but if that cannot be attained, a vacuum at 1,000 μm (1,000 micron) or lower is acceptable. To start the 8 h vacuum hold test, close the system charging valve connection to the vacuum pump.

  • Page 152 WARNING To avoid liquid freezing in the chiller tubes when removing refrigerant from a charged system, run the chilled water pumps. Maintain chilled liquid flow for the entire refrigerant recovery process. If water flow cannot be maintained, completely drain the chilled liquid from the chiller and the waterbox vents. Open all drains before beginning this process.

  • Page 153: Compressor And Motor Maintenance

    When all liquid refrigerant has been recovered, begin the vapor recovery process by connecting to any of the chiller vapor service connections so that the refrigerant vapor can be recovered and condensed into the refrigerant container. The chilled liquid pumps must remain operational for this process because the vapor pressures can drop significantly below the values that would cause water or brine to freeze.
