*If a machine con®guration other than 2-pass, 150 psig (1034 kPa), NIH waterbox con®guration is used, refer to Tables 3 and 4 to obtain the additional dry and water weights that must be added to the values shown in this table.

²Cooler and condenser weights shown are based upon 2-pass, nozzle-in-head (NIH) waterboxes with 150 psig (1034 kPa) covers. Includes components attached to cooler, but does not include suction/discharge, elbow, or other interconnecting piping.

**Dry weight includes all components attached to economizer: Covers, ¯oat valves, brackets, control center (31 lb [14 kg]), and power panel (20 lb [9 kg]). Dry weight does not include compressor weight, motor weight, or pumpout condensing unit weight. The pumpout condensing unit weight is 210 lb (95 kg). For compressor and motor weights, refer to Tables 6, 7, 8, 10A, and 10B.

²²Operating weight includes the sum of the dry weight, refrigerant weight, and water weight.
