    a. The chiller equipment requirements do not apply for chillers used in low-temperature applications where the design leaving fluid temperature is
    b Section 11 contains a complete specification of the referenced test procedure, including the referenced year version of the test procedure
    c. Compliance with this standard can be obtained by meeting the minimum requirements of Path A or Path B. However both the full load and IPLV must be met to fulfill the requirements of Path A and Path B
    d. Path B is intended for applications with significant operating time at part load. All Path B machines shall be equipped with demand limiting capable controls
    e. NA means that this requirement is not applicable and can not be used for compliance
    f. NR means that for this category there are no minimum requirements
    g. Only allowed to be used in heat recovery applications
    h. Packages that are not designed for operation at ARI Standard 550/590 test conditions (and, thus, cannot be tested to meet the requirements of Table C-3) of 44°F leaving chilledwater temperature and 85°F entering condenser-water temperature with 3 gpm/ton condenser-water flow shall have maximum full-load kW/ton and NPLV ratings adjusted using the following equation:
    Adjusted maximum full load kW/ton rating = (full load kW/ton from Table C-3) / Kadj
    Adjusted maximum NPLV rating = (IPLV from Table C-3) / Kadj
