*These weights are for reference only. To determine frame size, see Fig. 1.
NOTE: For Design I chillers, the 150 psig (1034 kPa) standard waterbox cover weights (NIH, 2-pass
cover) have been included in the heat exchanger weights shown in Table 12. Design II chillers are
equipped with a linear float, and chiller weight is based on a 300 psig (2066 kPa) waterbox with 1-pass
arrangement.
