*The 150 psig (1034 kPa) waterbox cover weights are included in the dry weight shown in Table 15. ²Two different waterbox covers are present on 2-pass chillers. The weight shown in this table represents the

weight of the waterbox cover that contains the nozzles. A blank waterbox cover is also present on 2-pass units. The weight of the blank waterbox cover is identical to the weight of the same size marine waterbox cover. Refer to Table 21.
